Revision history for Perl extension Imager.
0.01 Thu May 6 15:25:03 1999
- original version; created by h2xs 1.18
0.02 Mon May 10 20:20:20 1999
- Added PPM writer, and a new return type to
be used to return undef() from a function returning
(int)0.
0.03 Thu May 20 23:23:23 1999
- Added Pseudo image handling thingies, now
you can use your own get and put pixel routines.
0.04 Mon May 24 22:14:55 1999
- Rewrote parts of jpeg support.
0.05 Tue May 25 23:40:01 1999
- Added png support with libpng
fixed error reporting and return types from
some format routines.
0.06 Wed May 26 19:05:39 1999
- Fixed Data::Dumper being used when it shouldn't have
added feature checking to see at run time if
certain formats are avaliable.
removed some ancient C++ style comments that hadn't
been properly removed, some out of bounds errors in ppm.c
fixed tests so missing features are skipped.
0.07 Thu May 27 03:15:00 1999
- Fixed the typemap for i_img and i_color so that you can pass
a null pointer to them without getting a warning when warnings
are enabled. Maybe this is counter perl but it greatly increases
the usability of the functions.
0.08 Fri May 28 14:13:21 1999
- Added support for gif via, giflib or libungif.
gif is so ridden with patent issues but the user
can decide which library to use since they have the same
include files and calling interface.
0.09 Mon May 31 17:52:32 1999
- Added image scaling per axis - faster than doing both
axes at the same time. The current method uses lancoz
kernel and filtering. But more types should be added -
including: nearest neighbor, linear, and bicubic.
0.10 Mon Jun 7 03:25:54 1999
- Added T1 postscript font handling. It's very primitive
at the moment but creative people can do nice stuff
with it. Currently it is not possible to have it
generate an image of the correct size for a given string
but that is on the way.
0.11 Mon Jun 7 14:43:35 1999
- Added T1 features for direct to image rendering in
a single color. fixed some debug messages going to
stderr instead of a log file.
0.12 Tue Jun 8 02:58:43 1999
- Fixed bugs in jpeg.c when loading images. Also specified
prototype behaviour to on in the Imager.xs file. The
Makefile.PL step doesn't complain anymore so that is
hopefully fixed.
0.13 Wed Jun 9 06:55:58 1999
- Fixed Imager.xs for init_log call. Minor fixes here
and there.
0.14 Thu Jun 10 14:11:22 1999
- Rewrote most of the logging stuff so that it is now
possible to remove all logging from the XS part of the
module. Also some primitive check of memory usage was
added. Claes Jacobsson sent in some filters, inverter,
contrast and a noise filter.
0.15 Mon Jun 14 08:13:29 1999
- Wrote minor enhancement on the calling syntax list.
Started on the object interface - added better support
for quering avaliable filetypes. Fixed memory leaks in
most loaders. New filters from Claes in this version
are bumpmap, postlevels and mosaic.
0.16 Wed Jun 16 20:54:33 1999
- Added fixes to the BEGIN and END parts, added writer
function for the OO interface. Also added basic IPTC
reading support for jpegs. Also a few filters have been
added to the OO interface.
0.17 Thu Jun 24 11:09:15 1999
- Added dynamic loading stuff - It's still missing a nice
global symbol table. This will be fixed in next release.
also calling the plugins is not all to easy at the moment.
0.18 Mon Jun 28 12:31:33 1999
- Added global symbol table - plugins now need a symbol
table pointer in them. When the module is loaded it is
set to point at the global symbol table. Also some barebones
Makefile.PL has been made in the dynfilt directory - it works
on my system - I hope it does on yours.
0.19 Fri Jul 1 15:00:03 1999
- Added a way new scaling method for creating easy previews.
It only uses nearest neighbor, so it's doesn't look very nice
but it may be better for applications like remote sensing.
0.20 Mon Jul 5 10:15:37 1999
- Added and rewrote documentation.
0.21 Mon Jul 6 19:15:37 1999
- Fixed a bug in the scaling routine - it wasn't
handling 0< cases.
0.22 Sat Oct 9 07:04:14 1999
- Added a new method to write gif images - now
it is possible to have a part of a palette fixed.
this is very usefull if one needs to make sure that
some color like white is in the pallete. This method
also allows some ditherding and gives better colormap
than the mediancut from the gif libraries. It does
need much more cpu power though. Hopefully later versions
will be faster.
0.23 **************** Internal release only
- Fixed the %instances bug - caused ALL memory to be leaked.
Added real noise function - need feedback on how it should
be used. Also box(), and polyline are now in place. Polygon
is missing but antialiased line drawing with integer endpoints are
done but should be replaced with a version that can have
floating point endvalues. Two noise filters addded.
0.24 **************** Internal release only
- Converted i_color into an object from a reference, so now it's
giving an object instead of a void ptr or an integer or something.
0.25 **************** Internal release only
- Added basic Truetype functionality - still needs a rewrite
to be decent. Currently it's a port of a demo program that
uses an awful amount of global variables and there is much IO since
no caching of glyphs is done.
0.26 Tue Nov 23 03:57:00 1999 > Development release <
- Added transformations so that an image can be wrapped.
To achive decent speed a C based stackmachine is included. As a result
transformations need to be specified in rpn (postfix) notation. It
also can use the Affix::Infix2Postfix class to do the conversion for it.
0.27 Tue Dec 28 03:57:00 1999 > CPAN release <
- This is a bugfix version mostly, thanks to claes for pointing
out the problems - fixed palette saving wasn't working correctly after
version 0.24 - rather surprised this didn't crash everything.
Also fixed that for t1 fonts the bounding box wasn't being reported
unless the font had been used before. This is either a bug in t1lib
or a mistake in it's documentation. Another lingering bug since 0.24
what that $img->box() wasn't creating it's default color properly.
Added i_tt_text() method and more debuging to the truetype routines.
truetype testcase fixed and old debug rubish removed.
0.28 Tue Jan 4 05:25:58 2000 > CPAN release <
- Only fixes to truetype test and transformation tests.
Thanks to schinder of cpan testers for testing and reporting.
0.29 Tue Jan 4 21:49:57 2000 > CPAN release <
- fixes to get rid of warnings under pre 5.005,
Fixed broken preproccessor directives to work on non gnu
compilers. Fixed DSO test on HPUX - both code errors and
HPUX creates .sl instead of .so so the tests were failing.
0.30 Sun Jan 7 05:00:06 2000 > Bunch of Alpha releases <
- An attempt to automate installation.
0.31 Sat Jan 15 03:58:29 2000 > Fixes fixes fixes <
- Fixed a bug pointed out by Leolo where loading gifs
skips the first line of the imageload() has been
by read() - for now load is an alias for read. It will
be removed in the future. Also, fixes dynamic loading on
systems that prepend an underscore to symbols. At the present
the only system that I know of that needs this is OpenBSD.
BUT YOU MUST RECOMPILE ALL OF YOUR OLD MODULES AGAINST THIS BUILD.
Added getchannels() method ( How did I manage to delay this
untill now ). Some document changes but nothing substantial.
Also fixed the png read/write routines to handle all colorspaces
and images with alpha information. Also now it's possible to
have Imager guess the format of the files to load or save
when passing files to read or save from the filename.
Also all of the tests except dynamic loading now pass on OS/2.
0.32 Tue Feb 29 17:26:00 2000 CPAN RELEASE
- Added the getcolorcount method. Fixed interlace handling
on png images. Fixed the missing channel count in crop()
method. Rewrote most of t1lib database stuff - created color
and font classes. T1 stuff is mostly done - TT things were
rewritten too and now include most of what is needed for
pixmap caching. Added documentation for fonts. Comments have
been added to some of the relevant c-routines. Added a copy()
function in Imager.xs and a corresponding method name.
Changed the underlying data type for the raw XS images from
pointers to objects - this will hopefully catch the most
basic errors and keep the segfaulting down. This means that
all of the underlying XS calls for readjpeg, readgif, readpng
and readraw do not take the first parameter any more.
Made fixes to keep it not spewing warning on 5.004 perl.
**** If you had any code that didn't use the OO interface ****
**** It will probably not work any longer ****
0.33 Beta -- No final
- Fixed the end message from Imager 0.32. Destroy called
on an empty image. Did some work on the polygon method.
Some clean up in the Makefile.PL script. Fixed a buffer
overrun in the t_transform in Imager.XS. Fixed the
error handling in the jpeg loader. It now correctly
returns undef if a load on an image fails. It also
sends the error messages to the log file. Added errstr()
method to the image object. Added a new way to read()
objects from scalars. So far this is only implemented for
jpeg, png and gif. ppm and raw soon - as always if someone
wants to do an overhaul on the ppm stuff feel free. It seems
like such a basic format that interfacing with a library is more
work than implementing all of the needed routines instead.
0.34 Beta -- No final
- Bunch of documentation fixes, backed out ppm code.
Put in TonyC's giant transform2 patch. Fixed the patch
to make it ansi compliant. Fixed a bunch of bugs in the
Freetype code with regard to vertical and horizontal
positioning and bounding boxes. Cleaned up a lot of the
code so it runs under -Wall. Code that is still in
development such as the polygon converter do not compile
cleanly. Fixed the non antialiased versions of truetype
dump to image routines. Also removed the FIXME for the
hardcoding of antialias in the Imager string method.
Fixed sign error and a missing cache of the bounding box
calculation for the rasterize function. Removed some
debugging code I forgot to remove. Added iolayer.h
and iolayer.c but they don't do anything for now.
0.35 pre2 -- No time yet
- Fixed some compile warnings for various files under -Wall.
Added functionality for jpeg reading of seekable files, it's not
really working yet. This version is pretty much *not* working.
Do not install unless you intend to do a lot of development.
Repeat - it doesn't even pass tests (but it compiles). Ok now reading
jpegs works from scalars, my guess is that it also works from non
seeking sources such as sockets or pipes.
0.35 pre3 - No time yet
- Added the *right* patch from Tony which combines
the common code from i_readgif and i_readgif_scalar into
i_readgif_low. Added tiff reading support through iolayer.
0.35 pre4 - No time yet
- Added tiff writing (no options) support through
iolayer. Also made some small fixes for the iolayer reading
(was always doing two reads when one was needed). Patched the
Imager::read() call so that it now uses a mixture of old and new
functions.
0.35 pre5 - No time yet
- Fixed various gnu'isms in the c code (some bugs in the link list
implmentation). Fixed missing #skip codes when gif format is not
present in any form. Added fixes for 5.004_04 in the transform2 function.
Made sure it compiles cleanly with sun's cc. Switched from a .jpeg
for transform2 check to a .ppm file so it runs when jpeg is not
present. Added a test for tiff files in t10formats.t.
0.35 pre6 - No time yet
- Fixes to Makefile.PL. Should find freetype includes on more
distributions now. Ran tests on Solaris and Hpux, minor fixes.
Compiles with some warnings on with both hpux and solaris' cc.
Made some minor changes to the documentation. Fixes to tiff.c log
code.
0.35 pre7 - No time yet
- Fixes 64 bit bug on freebsd. While libtiff mirrors the effects of
lseek it's toff_t is a uint32, while lseek uses off_t which can be a 64
bit quantity. Added the IM_LFLAGS environment variable to help
people with broken libgifs (that want to link with X).
0.35 Sun Jan 28 19:42:59 EST 2001
- More makefile fixes, fixed a few signedness warnings.
Checked to see if it compiled cleanly on Solaris and HPUX.
Fixed a 5.004_04 warning and added more ENV flags for makefile.
0.36 Mon Jan 29 09:36:11 EST 2001
- String as 0 or "" caused an error in $img->string(). Fixed a
documentation error invoving string() method syntax. Merged a patch
for non antialised truetype fonts. Fixed an error in the Makefile.PL
which caused a makefile to be generated that bombed with sgi's make.
0.37 Mon Tue 30 09:36:11 EST 2001
- Several documentation fixes. Pod documentation for almost every
function in image.c. Added sys/types.h include in iolayer which was
causing problems on various linux systems.
0.38 pre1 - No time yet
- Fixed a braindamaged fix on the Makefile.PL file. Moved the
code for Imager::Color into lib/Imager/Color.pm. Wrote some pod
about how it works. Made the names of Imager::Color XS routines
all begin with ICL_ and used the prefix rules of XS to get nice names
in perl. Found a bug (not fixed) in how XS handles
returning an object to an object it had as a parameter (double
free).
0.38 pre2 - No time yet
- Fixes lots of for documentation, patch for freetype bounding
box handling. Split put code for Imager::Font into Font.pm and added
more documentation for Font.pm. Added string local ascender and
descender for tt fonts. Note that this needs to be added to t1 fonts
before 0.38 final.
0.38 pre3 - No time yet
- Fixed an in consistency in the bounding box functions for t1
fonts. Now both versions get the 6 argument bounding_box method
described in Imager::Font. Started converting the comments in
font.c so that they are viewable by doco.perl. Added two examples
of filters. Need to make them more usefull and then add more
notes than are in compile.txt.
0.38 pre4 - No time yet
- Completed adding pod comments to font.c, tiff.c and iolayer.c.
Those along with image.c should now have every single function
described in pod format.
0.38 pre5 - No time yet
- Replaced ppm.c with pnm.c which adds support for pbm/pgm/ppm
files ascii and binary formats. Added patches for the gif routines.
Patched some of the color quantizing routines (Leolo and TonyC).
There is one bomb and one warning in this test, and frankly I don't
see why they are suddenly there.
0.38 pre6 - No time yet
- Patch from Tony that fixes infix when Parse::RecDescent is present.
Checked some cases where malloc/free were used instead of mymalloc/myfree.
Added bufchain iolayer code. You can now write to a chain of buffers and
later slurp it all into a single perl scalar. Found some oddity of t/t10
test not giving the right return value when malloc debugging was enabled.
Fixed some of the logging code and the malloc debugging options. Added
more tests for tiffs.
0.38 pre7 - No time yet
- Added i_gradgen code and put it into the filters hash. Think a
seperate pod for filters would be a good idea. Also removed some of the
debugging code from the iolayer. Added pod comments to filters.c and
looked over the code.
0.38 pre8 - No time yet
- limited Win32 support, Imager installs and builds using VC++,
but there's no image/font format support yet.
0.38 pre9 - No time yet
- Added lots of color quantization code from Tony with benchmarks.
Also fixes ugly stack overrun in old version. Added fixes for the lmfixed
problem. Four of them, let's see which is fastest. This version adds
some voronoi partitioning - it's dog slow but it's a reference implementation
to check if faster algorithms are doing the right thing [tm]. Added a check
for giflib 3.
- Win32 support for libpng
- fixed set_internal creating 2 refs to one object
- Win32 support for jpeg
- Win32 support for tiff
- base level error reporting code added, I still need to modify
older code to use it
- fix translate=>'giflib' handling of single-colour images.
Previously a single colour image would cause an error in
MakeMapObject().
- fix t/t10formats.t tests against giflib3
- added test for transparent gifs
- minor doc fixes for transparent gifs
- make it less error-prone to write transparent gifs
- documented the options for reading raw images
- Changes switched to use spaces for formatting
- switch gif.c to new error reporting with related changes to
Imager.xs, Imager.pm
- each of the image formats now have their own test file,
extracted from t10formats.t, usually with som extra tests
- Added flip() and docs to Imager.pm and i_flipxy to image.c.
Added testcases too.
- Fixed an overflow bug in png.c
- added the colors parameter to Imager::read() which receives
the arrayref of colours that i_readgif(_scalar) returns
- fixed a problem in makemap_addi in quant.c where only the first
image was compared against the palette when the palette was being
refined. I screwed up on this originally (TC). This is the other
half of a fix for Leolo's lmfixed problem <sigh>.
- makemap_addi() now only puts colours into the palette that it
found while optimizing the palette (so we don't get 256 colour
palettes for 2 colour images :)
- initial implementation of a row-based interface to low-level
images (for performance)
- changed Imager::read() for GIF so that the arrayref pointed to
by the ref supplied in colors contains Imager::Color objects
instead of more arrayrefs, keep this interface stable until we
can make an informed choice about i_readgif()
- incorporated Micksa's faxable tiff support, treating as a type
of tiff rather than a separate format
- t/t70newgif.t now checks for gif support
- added the convert() method
- Added support for transparent to alpha conversion during loading
of png files. Note that libpng 1.0.1 is broken in handling this,
we know that 1.0.5 works.
- support for writing PGM (portable gray map) files
- Fix for i_gifread_low() for images with only a local and no global
colormap and an abort if no colormap is present (which is legal
in gif).
- several fixes to i_readgif_low()
- Fixed crop() method so that it is consistent with documentation.
- make clean now removes the testout directory
- added tests for the OO interface for tiff, added an option to
choose the resolution for fax tiffs, removed some unused code,
fixed minor problems with Imager::write() handling of image types
- changed README note on libgif bug to refer to t105gif.t instead
of t10formats.t
0.39 pre1
- split Imager::Font into a base, *::Type1 and *::Truetype

- tests for rubthru
- rubthru can now rub a 2 channel image over a 1 or 3 channel
image

- added gaussian to the filters list
- documented the individual filters
- fixed the right-hand side of bounding boxes for TT fonts
where the last character overlaps the advance width (eg.
italic fonts)
- added rotation by exact amounts in degrees or radians,
implemented using the matrix idea from Addi. The procedural
matrix transformer is exposed, but still needs testing (as XS)
and needs an OO interface, hopefully with some helper tools,
like the preset interface with ->convert().
- MY::postamble() in Makefile.PL included a broken rule
(Makefile.PL 1.13.2.5)
- support for GDI fonts under Win32
- made that work for cygwin too (needs the w32api package)
- freetype1 support under Win32
- t1lib support under Win32
- fixed a minor bug in font.c (invalid font files caused a SEGV)
- checked cygwin for both t1lib and freetype1
- freetype 2 support
- exposed the matrix_transform() function to the OO interface

- support for setting the resolution when writing to PNG
- retrieve physical resolution to tags when reading from PNG
- found an XS bug in the interface to i_tags_add()
- fixed handling of writing text to a channel with freetype2
(sometimes the edge of a character would damage the edge of the
previous character)
- some utf8 support for freetype2
- some vertical layout support for freetype2
- named parameters for specifying colors, with quite a few options.
- glyph size issues for freetyp2
- minor problem in handling of canon option

- implement i_flood_cfill() based on i_flood_fill, and
add general fills to the flood_fill() method
- generalize the combine parameter to get different ways of
combining the fill with the target
- the tt driver (freetype 1) didn't handle the first character
hanging off the left of the character cell
- the tt driver produces some artifacts when characters
overlapped
- error handling for writing jpeg images
- writing paletted images to GIF now uses the image palette
if it's small enough
- $img->arc() now calls i_circle_aa() if a complete circle is
being drawn in a plain color
- image based fills
- unsharp mask
- make i_conv() clamp the bottom end of the samples range too
(makes it useful for sharpening)
- adjust ascender/descender values for FT1.x to avoid losing
descenders (specifically the bottom of "g" in ImUgly.ttf or
arial.ttf at 14pixels)
- added tga.c to read targa images
- added i_bumpmap_complex to do more accurate bumpmapping
- added an image type with doubles as samples
- change i_copy() and i_sametype() to handle double/sample images
- added basic POD to trans2.c
- transform2 now uses the error interface
- myrealloc() is implemented for malloc debug mode
- now buffer chains are freed when destructor for Imager::IO
is called
- adjusted the Lanczos window width for the scaling code and
added code to normalize the filter generated to preserve
intensity scaling.
- constant edge extension for scaling operations
- better error checking of automatic fill conversions

- tiff reading now uses the error stack
- use the error stack value from reading bmp files
- fix an error message in bmp.c
- added has_chars() method to Imager::Font::FreeType2
- freetype 2 bounding box function didn't know UTF8 (doh!)
- write paletted images as paletted to tiff
- initialize counter for packing 4 bit data
- don't allocate hashboxes as locals since it overflows the
stack by default in Darwin
- applied T1 afm patch from Claes Jacobsson
- split IM_INCPATH and IM_LIBPATH with $Config{path_sep}, so they
work on Windows
- Added memory pools for easy cleanup of temp buffers

- modify the Freetype2 font code to pick it's own encoding
rather than using whatever strange translation FT2 happens to
pick
- modify the FT1 font code to use the first encoding as a default
if we don't find a unicode encoding
- use the glyph bbox to calculate the glyph bitmaps for rendering
with FT1 rather than the global ascender/descender. This helps
with fonts that have broken metrics.
- fix calculation of descender for FT2, it was calculating the
minimum decent rather than the maximum for the characters in
the string
- didn't set default for bounding_box() utf8 parameter (caused a
warning when calling bounding_box() on a FT2 font with no utf8
parameter)
- Added lib/Imager/Draw.pod documentation of primitives.

- we now log which memory block is being freed before giving
an error on it being re-freed
- fixed stupid bug in deleting tags
- fixed minor pod errors involving >
0.40pre2
- make t1log optional, defaulting to off. You can enable the log
with Imager::init(t1log=>1) (Ticket #369)
- quote a few hash key strings to prevent warnings on 5.004
- modify quantization code to handle 1 channel images
correctly (Ticket #365)
- make channel pointer to i_gsamp() const int * so we can pass
const arrays
- handle the presence of the default broken giflib better,
by giving them some more prose about the problem, and skipping
all but the first test that fails with the broken giflib
- i_box_cfill() went into an infinite loop on fountain fills
or fills on images with more than 8-bits/sample
- hide more of our Darwin dlload emulation to prevent runtime
symbol conflicts
- use INT2PTR() and PTR2IV() macros instead of direct casts to
prevent pointer vs int size warnings on 64-bit builds of perl.
- add our own INT2PTR and PTR2IV definitions when perl doesn't
supply them
- difference() method
- hide (with static) or rename many symbols that could possibly
cause conflicts with other libraries or perl
- Fix runaway cache problem for freetype1 font cache.
- Added version logging when log is started.
0.40
- difference() wasn't setting an alpha channel when the input
image didn't have one
- improve crop() documentation, see
http://perlmonks.org/index.pl?lastnode_id=155767&node_id=155428
- handle the first "buggy giflib" test more portably. Previously
it used fork() which caused problems on systems that didn't have
a real fork().
0.41
- skip() in testtools should be skipn() and it should use the
loop variable for the test number
0.42
- quote the 'min' parameter to scale in Imager::Transformations
and at least mention it in the docs beyond the examples
- document the values for the read() and write() method type
parameter
- support UTF8 text with Freetype 1.x
- second parameter to SvPV() must be of type STRLEN
- Doc pathces from cogent.
- Fixed out of bounds access on bitmap for flood fills.
- some char * vs unsigned char * casts missing on OSF1 v4.0
- some enums had , on the last item in datatypes.h, which OSF1
didn't like
- Compaq C 6.4 (OSF1) claims to be C99 but doesn't provide
stdint.h, don't try to use it under OSF

specific to Imager::Font::Type1
- mc_web_map was storing colors with an alpha of 0
- update the URLs for libpng and zlib
- Fixed empty string handling for tt font driver.
- Fixed tiff handling of images all contained in a
single strip (rowsperstrip = -1) and added a hack
for images missing the rowsperstrip tag.
- Fixed default parameters for crop()
- Added Preliminary specialized scaling code.
- Added image type detection.
- added smoke test for win32 font bounding_box() method, and
fixed the problem reported in ticket #1748.
- update t37w32font.t to use i_line() instead of i_draw()
- replaced non-portable call to rint() with (int)(dy+0.5) (so we
can build on Win32)
- the default tifflib warning handler was crashing on Win32
under ActivePerl, when an unrecognized tag was read from the
file. For now we'll just drop the warnings in the bit bucket.
(Ticket #1513)
- the code to read multiple tiffs didn't handle files with more
than five images correctly, causing a memory overrun.
- fix some minor test code hiccups
- implemented i_t1_has_chars(), tests for same
- added ExistenceTest.{pfb,afm,ttf} for testing $font->has_chars
- tests for Imager::Font::Type1::has_chars();
- tests for Imager::Font::Truetype::has_chars();
- internal and external bounding box calculations now use
the same hint flags as text output for Freetype 2.x
- made the i_foo_bbox() interface more expandable by using
symbolic constants for the sizes and array offsets
- added a / character to the ExistenceTest.foo fonts that
overlaps the right side of the character cell, to test the
advance width reporting.
- added advance width to the i_foo_bbox() interface, and
implemented it for FT2, FT1 and Type 1
- Imager::Font::bounding_box() now returns an Imager::Font::BBox
object in scalar context.
- implemented $font->align() text output method, for simple output
of aligned text
- created Imager::Font::Wrap::wrap_text to perform simple text
wrapping
- FT1, FT2 and T1 fonts now support the face_name method
- FT1, FT2 and T1 now support the glyph_names() method
- Debian woody supplied FT2.0.9, which didn't support
FT_Has_PS_Names(), so we use the FT_HAS_GLYPH_NAMES() macro
instead.
- some older FT1 don't define TT_MS_LANGID_ENGLISH_GENERAL,
which we use, define it if freetype doesn't.
- Added extra options to rubthrough() so only a subpart of
source image is used.
- the image fills didn't handle filling with source images of
less than four channels correctly
- added comment support the postfix transform2() expression
parser
- transform2() can now produce images with other than 3 channels.
- added a correct T_AVREF input mapping to the typemap to
simplify parameter lists
- shut off one of the align subtests in the ft2 test. The triggering
is likely an ft2 bug.
- removed some half written scaling optimization code.
- added /sw/lib and /sw/include to the Makefile.PL code for osX.
- removed all references to the www.eecs.umich.edu page and changed
them to imager.perl.org ones.
0.43
- added log() and exp() functions to transform2()
- change the getpN() functions in transform2() to set a
reasonable alpha if the input image has no alpha
- document the constants that transform2() defines
- skip the right number of tests when FT2 isn't available
- This version pushed to CPAN because of skip problem in FT2 test.
0.43_01 Fri 8 Oct 2004
- only call FT_Get_Postscript_Name() on FT 2.0.6 and later
- put the IM_LIBPATH and IM_INCPATH values first in the search
path so the builder gets their local versions if desired rather
than the system versions they might be trying to avoid
- document the exp() and log() transform2() functions
- document the constants normally set by transform2().
- refer the user to appropriate documents in the example in
Imager.pm
- change the list of documents in Imager.pm to move the document
names out of the =item lines so we can make them into links
- the scale() method now produces a warning when called in
void context.
- font.c now only uses the defined T1Lib error codes
- update ppport.h and remove the duplicate definitions from
Imager.xs. Had to mangle ppport.h to prevent duplicate global
function definitions.
- newer versions of tifflib require that all of the function
pointers passed to TIFFClientOpen be non-NULL, the mmap() and
munmap() pointers were always NULL and the sizeproc was
sometimes NULL.
- there would be a link or load time error on m_init_log() if
Imager was built with IM_NOLOG, fixed by renamed init_log()
to m_init_log() in log.c (thanks to Takumi Yamani)
- moved some variable definitions to the right place
- the Win32 font driver bounding box function now returns the
right number of values (both thanks to Takumi Yamani)
- the Win32 font driver now uses DEFAULT_CHARSET rather than
ANSI_CHARSET are the lfCharSet value for the LOGFONT,
as suggested by Takumi Yamani.
- fontfiles/ExistenceTest.{pfb,ttf} weren't marked as
binary in the CVS repository (caused test failures if you
built from CVS on Win32)
- Makefile.PL should now handle INCLUDE or LIB with spaces in them
correctly on Win32.
- the pnm reader read maxval for ppm/pgm files and then ignored it,
it's now validated (0 < maxval < 65536) and used to scale
samples. Note that binary ppm/pgm files (P6/P5) with maxval >
255 result in an error, since I didn't want to add new features
just yet, just get the code that's there working correctly.
Thanks to Elthek on rhizo for reporting this and help in
tracking it down.
Resolves https://rt.cpan.org/Ticket/Display.html?id=7465
- added a bunch of tests for reading pnm files.
- previously, if you supplied to_paletted and empty color map
and set make_colors to 'none', quant_translate() would segfault.
This was because it was making the reasonable assumption that
you'd have colors to map to. quant_translate() now checks there
is at least one color and return NULL if there isn't.
- i_img_to_pal() now does error checking of the value returned by
quant_translate().
- Imager::to_paletted() now checks for success/failure of
i_img_to_pal() correctly and does appropriate error handling.
- i_writegif_low() did no error checking on the result of
quant_translate(), it now does
- we now test that trying to write a GIF image with no palette
allowable by the quant options is a failure.
- Imager::write() was doing nothing with the result of the call
to i_writegif_gen(), in particular it wasn't returning () on
failure.
- added tests for paletted image handling and the methods
specific to those images
- the XS for i_setcolors() was missing the OUTPUT clause for
RETVAL, and hence wasn't returning failure on failure.
- supplying a sufficiently small scaling value could make the
scale() method return an image with zero height or width.
Several of the above together resolve
https://rt.cpan.org/Ticket/Display.html?id=7467
- the void context warning for scale() now includes the callers
filename/line (instead of the default of Imager.pm line 15xx)
- Imager->new will now return undef if the dimensions or number of
channels specified for an image are out of range. An error
message can be retrieved with Imager->errstr.
- added the C<builtin> color specifier and the
Imager::Color::Table class which defines those colors.
Resolves https://rt.cpan.org/Ticket/Display.html?id=2593
- added the equals() method to Imager::Color.
Resolves https://rt.cpan.org/Ticket/Display.html?id=2238
- prevent a test warning introduced by the above
- the rotate() and matrix_transform() methods now accept a 'back'
parameter specifying a background color. This is only used
where there is no source data (think of the corners around an
image rotated 45 degrees) and it not combined with transparent
pixels from the source image.
Resolves https://rt.cpan.org/Ticket/Display.html?id=6140
- removed a warning generated by the new matrix_transform() test
- added a method index to Imager.pm
- corrected "flood fill" to "flood_fill" in Imager/Draw.pod
- removed compose() method from Imager/Transformations.pod since
it isn't implemented yet
- the image resulting from a crop is now the same type as the
source image (paletted vs direct, bits/sample)
Resolves https://rt.cpan.org/Ticket/Display.html?id=7578
- the parameters to crop() weren't handled correctly in most
cases other than supplying left,top,right,bottom.
- clarified the documentation for crop() providing more detail
and more examples
- the edges of the cropped area are now cropped against the
edges of the source image
- cropping to zero width/height is treated as an error (no
image is returned and $src->errstr has a message)

- built 0.43_01 for testing
0.43_02 Mon 26 Oct 2004
- the changes to scale() had some problems with integer vs floating point
calculations (only caught in tests under perl 5.8.5 <sigh>)
- the FT2 glyph_names() method didn't do correct error handling
when the string parameter wasn't supplied
- i_ft2_glyph_name() accepted only an unsigned char as the
character code to get the name for, which meant it
didn't work for unicode characters \x{100} or above
- the XS for i_ft2_glyph_name() had a similar problem
- added NameTest.ttf to be used in checking unicode glyph
names
- added reliable_only optional parameter to the glyph_names()
method so you can ignore theresult of FT_Has_PS_Glyph_Names()
- handle errors given by i_ft2_glyph_name() a bit more
correctly
- the FT1 glyph_names() method didn't do correct error handling
when the string parameter wasn't supplied
- some memory allocated when creating a callback IO object (io_new_cb)
wasn't being released (detected with valgrind)
- the testtools.pl match[nx]() functions escapes the test string on
test failure a bit better
- the XS code for i_tt_glyph_name() used unsigned char to store a
unicode character when it should have used unsigned long.
- the XS code for i_t1_glyph_name() used unsigned char to store a
unicode character when it should have used unsigned long.
- resolves https://rt.cpan.org/Ticket/Display.html?id=7949
- the type 1 glyph_names() method didn't do correct error handling
when the string parameter wasn't supplied
- renamed io.h to imio.h to prevent problems building under cygwin.
resolve https://rt.cpan.org/Ticket/Display.html?id=7948
- i_writegif_low() wasn't setting the returned global palette, which
meant a rubbish palette was returned to the user (detected with valgrind)
- built 0.43_02 for testing
0.43_03 Wed 8 Dec 2004
- change the "double-include" protection macro that imio.h uses.
- updated download locations for the various libraries that Imager
depends on. Added some advice for cygwin.
- more information on gif library versions in README and Makefile.PL
- creating an image where the size of the allocated image buffer would
overflow an integer would cause too small a buffer to be allocated.
This could potentially be a security hole.
partly resolves https://rt.cpan.org/Ticket/Display.html?id=8213
- set i_format to jpeg for jpeg files and test for it
- set i_format to png when reading png files and test for it
- i_yres was being set to the xres when reading a png file
- added many bad BMP files to test various code paths in bmp.c, and
made many minor fixes to bmp.c to make them work:
- it was possible for various types of read failures to SEGV, both
as NULL pointer dereferences and buffer overflows
- some errors, like palettes being too large for the number of bits
per pixel, were not being caught
- failing to read all of a packed data structure would not cause
a read failure
- invalid compression types were not always caught
- error messages are more consistent (still not always great messages,
but one step at a time)
- added bmp_compression_name, bmp_used_colors, bmp_filesize, bmp_bit_count
tags on reading a BMP file
- added tools/imager to the distribution. This is still very
experimental and untested. Patches welcome, if you write tests to go
with them.
- the BMP reader now validates the bfOffBits value from the BMP header
and skips to that offset before reading image data. Previously this
value was read but otherwise ignored.
- added --palette action to tools/imager
- i_img_pal_new() now releases the image object memory if creation
fails.
- set i_format to gif when reading gif files and test for it
- set i_format to pnm when reading pnm files and test for it
- set i_format to tga when reading tga files and test for it
- handle image creation failures when reading tga files
- set i_format to tiff when reading tiff images and test for it
- handle image creation failures when reading tiff files
- test t/t35ttfont.t no longer requires TTFONTTEST to be set (and
hasn't for a long time,) removed that requirement from README
- updated home page URLs throughout the .pods
- added information on reporting bugs to the SUPPORT section of Imager.pm
- regops.perl now sorts the dumped data structure to produce minimal diffs
- quant.c now checks for integer overflow allocating its image data
- i_readraw_wiol() now checks for image creation failure
- i_readrgb_wiol() now checks for image creation failure
- i_writergb_wiol() was an empty stub, it now pushes an error message
and explicitly returns failure.
- i_readrgb_wiol() now sets i_format to rgb.
- set i_format to raw when reading tga files and test for it
- document i_format tag
- some tests were using $Config{ivsize} when they should have been
using $Config{intsize}
Resolves: https://rt.cpan.org/Ticket/Display.html?id=8645
- tools/imager has been removed from the MANIFEST, it's way too late
to test/debug for 0.44.
- image.h had no prototype for i_ft2_bbox_r() and it was being called
from Imager.xs
- giflib 4.1.3 still doesn't have all the bugs fixed, update the notes
in README and in the buggy_giflib.txt file that t105gif.t produces
- make the inclusion of NO_META dependent on the version of EU::MM.
I was going to include a META.yml but EU::MM's generation is too
simplistic (and misses the leading document header too). For now
I'll leave it out.
- built 0.43_03 for testing
0.44 Wed 15 Dec 2004
- modify the default include directories list to include the location
FreeBSD keeps freetype1 headers after the freetype2 locations.
This ensures that the -I options are generated with freetype2
locations first, so that those directories are searched before
the freetype1 directories. This prevents problems compiling
font.c on FreeBSD.
Resolves: http://rt-cpan.fsck.com/Ticket/Display.html?id=1723
- finish off a sentence in the "Producing an image from a CGI script"
example in Imager::Files
- method index didn't include errstr()
- document that you don't want the FT2 freetype.h in the include path
0.44_01 Tue 24 May 2005
- the plugins Makefile has long produced an error after all tests were
complete on Win32, finally tracked down why
- Makefile.PL now checks the directories specified by $Config{locincpth}
and $Config{loclibpth} for includes and libraries respectively.
Resolves: https://rt.cpan.org/Ticket/Display.html?id=2942
- we were undefing the wrong macro (used as an include guard) when
building the error code translation function for freetype 2. This
meant most errors came out as numbers.
- add a note to the README on how to get font suitcases and dfont files
working on OS X.
- add dfont to the list of extensions supported by ft2
- document Imager::Font->new()'s index parameter
- added concept index to Imager.pm's POD
- the gradgen filter now does the same color value conversion that
Imager's drawing functions do.
- added trivial multiple master support via the FT2 driver
- added .pcf and .pcf.gz to the list of extensions supported by ft2
- the tiff reader now puts warning messages produced during reading into
the i_warning tag.
Resolves: https://rt.cpan.org/Ticket/Display.html?id=8722
- the i_xres and i_yres tags are now stored in a resolution similar
to their source.
Resolves: https://rt.cpan.org/Ticket/Display.html?id=8520
- added tiff_resolutionunit_name tag when reading tiff files
- Makefile.PL now attempts to use freetype-config to configure freetype 2
and pkg-config to configure libpng.
- avoid complaining about include/lib directories we pull from
perl's config or we have built-in
- Makefile.PL now builds imconfig.h with #defines for libraries
present (and for the GIF library version) rather than putting them
into CFLAGS
- scanning for required include files is now down by directory rather
than by file, using -e to check for the existence for a file rather than
doing an eq against every filename in the directory.
- previously we only checked a candidate include directory for freetype.h
to consider it a valid FT1.x include directory. We now check if it
