  1. switch to using size_t and i_img_dim strictly

    authored
    Also, use double instead of float where the value is used in
    calculating a co-ordinate, since float may not be able to represent an
    image ordinate with sufficient precision

  1. - constify the Imager API

    Tony Cook authored
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

    - double per sample images were ignoring the channel mask.

  1. - creating an image where the size of the allocated image buffer would

    Tony Cook authored
      overflow an integer would cause too small a buffer to be allocated.
      This could potentially be a security hole.

  1. - previously, if you supplied to_paletted and empty color map

    Tony Cook authored
              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.
            - 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.
