    commit ddb433c
    Author: Tony Cook <tony@develop-help.com>
    Date:   Sat Sep 17 13:16:00 2011 +1000
    
        improve i_io_peekn() / i_io_read_fill() interaction
    
        a peekn() for a small amount no longer limits a following peekn() for
        a larger amount
    
        it also handles partly consumed input buffers

    Date:   Sat Sep 10 15:07:00 2011 +1000
    
        remove buffering from the PNM reader
    
    commit 8c2fe37
    Author: Tony Cook <tony@develop-help.com>
    Date:   Sat Sep 10 14:00:10 2011 +1000
    
        remove buffering from the callback IO object implementation
    
           - the callback IO object did its own buffering, controlled by the
             maxbuffer parameter supplied to the read() and write() methods.
             This buffering has been removed, to avoid redundancy with the
             common io_glue buffering.
    
           - the callback IO object new tests the result of calling the close
             callback, which should return true for success.

    commit dce56aa
    Author: Tony Cook <tony@develop-help.com>
    Date:   Sat Sep 10 00:01:23 2011 +1000
    
        buffering working
    
        Todo:
    
        - some file handlers don't check the result of i_io_close(), test that
          (with a close callback handler), fix that
    
        - remove other buffering implementations where possible, the callback
          code (Imager.xs) and pnm.c in particular
    
        - allow _get_writer() to produce unbuffered writers
    
        - add coverage tests for the buffering code

        eliminate the final remnants of io_glue_commit_types()
    
        it's not part of the API and has been a no-op for years

    Also, use double instead of float where the value is used in

  1. Various changes:

    Tony Cook authored
     - fix drawing text on 2/4 channel images for FT2
     - reading ASCII PBMs was broken, it assumed there was whitespace 
       between samples but there doesn't need to be
     - add makemap type of mono/monochrome for producing monochrome images
     - roughly tripled speed of reading any sort of PNM
     - reading a pnm can now return a partial image if you set allow_partial
     - reading a bmp can now return a partial image if you set allow_partial
     - we can now read 16-bit/sample binary PGM/PPM images
     - we can now write 16-bit/sample binary PGM/PPM files if explicitly 
       requested (since GIMP can't read them)
     - reading a tiff will now only return an incomplete image if you set 
       allow_partial
     - some documentation reformatting
Commits on Jan 10, 2006
  1. - start of external Imager API access:

    Tony Cook authored
      - rename headers to avoid conflicts:
        - image.h to imager.h
        - imagei.h to imageri.h
        - datatypes.h to imdatatypes.h
        - config.h to imconfig.h (created by Makefile.PL)
      - moved all public types defined in imager.h to imdatatypes.h
      - supply the PM parameter to WriteMakefile(), to install headers 
        under Imager/include, and the Imager typemap in Imager/typemap.
        We scan the MANIFEST for files to add to PM.
      - add "i_" prefix on some functions useful as public at the C level.
      - moved the typedefs that support the typemap from Imager.xs to 
        imperl.h
      - set the global callbacks hook in the Imager.xs BOOT section
      - API cleanup:
        - define i_tags_set(), i_tags_setn() - we might not allow multiple 
          values for a tag in the future
        - i_copy() now returns a new image instead of doing horrible inplace
          things to an existing image
        - provide actual functions for all of the macros we define in imager.h
          so we can put them in the global callbacks structure
      - define global functions structure (imexttypes.h)
        and initialize it (imext.c)
      - add API include header with macros to setup the define and
        initialize the local callbacks pointer, and macros to call the API
        functions.
      - build Imager::APIRef from C sources, including updating the sources
        to include documentation for each API function.
      - convert dyntest and mandelbrot dynfilts into XS modules (too easy)
      - simple Imager::CountColor example
    - support Inline::C :
      - typemap changes to accept Imager or Imager::ImgRaw objects as 
        image parameters
      - define Imager output type for trivial cases of returning an i_img as
        a full Imager object
      - Inline WITH hook to filter Imager XS types into types Inline::C can
        accept, supply appropriate headers and initialization.
      - test script t/t82inline.t
    - try to use XSLoader instead of DynaLoader (but fallback if necessary)
    - paste() can now paste a subset of the source image.
    - paste() now has better tests
    - paste() should now be faster for larger pastes

  1. - convert t/t107bmp.t to Test::More

    - convert t/t108tga.t to Test::More
    - error messages generated reading JPEG or PNG images are now
      available via errstr()
    - implement/test/document set_file_limits()/get_file_limits() methods,
      which allow limits on the size of image files read.

  1. - the pnm reader read maxval for ppm/pgm files and then ignored it,

    Tony Cook authored
              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.
            - added a bunch of tests for reading pnm files.
