Imager

Changes for version 0.47_01

set the locale to "C" properly when testing ft1.x error messages
don't destroy image before creating it in error handling in bmp.c
extra concept index entries
Imager::Draw - align_string()'s valign parameter was invalid in the synopsis
start of external Imager API access:
- 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
added sample files missing from MANIFEST
added t/t92samples.t to check samples/README against MANIFEST
added inline_replace_color.pl to samples
constify the Imager API
document Imager::Filter::Mandelbrot
convert dynfilt/flines.c to Imager::Filter::Flines
minor changes for older perl/ExtUtils::MM
deal with freetype-config --cflags returning the directories in the wrong order (Freetype 2.1.4 and earlier) Thanks to David Wheeler for his help in tracking this down.
reword and provide an example for non-proportionally scaling an image. Wording from Simon Cozens.
error messages when writing TIFF images were always 'Could not write to buffer', more useful messages are now reported.
error messages when writing PNM images were always 'unable to write pnm image', more useful messages are now reported.
convert t/t103raw.t to Test::More
reading a raw image no longer exits on a short read or read error, and returns an appropriate error message in $im->errstr
write failures when writing a raw image now return a useful message in $im->errstr
added typemap type names to types in Imager::API.
make skip when Inline::C not available less verbose
convert t/t07iolayer.t to Test::More
handle the possibility of strerror() returning NULL.
supply C<imager> parameter to filters so we can register filters implemented in perl.
document register_filter() and add test for it
add example to SYNOPSIS of samples/inline_replace_color.pl
minor POD fix in Imager::Color::Table
eliminate many -Wall warnings
update README to match unbuggy giflib
document index parameter of Imager::Font->new()
change faxable output to use a more fax natural PHOTOMETRIC_MINISWHITE, since T.4 normally works that way, and MINISBLACK confuses some readers.
clean up scale() method for readability
make scale() fail if an invalid type is supplied (previously documented as undefined behaviour)
add error handling tests for scale()
smarter warning removal
handle effects of byte ordering when testing tiff error messages
scale() can now expect an Image::Math::Constrain object as a scaling constraint via the constrain parameter.
added tests for the various ways we can specify scaling size
documented scale()'s scalefactor parameter
sick of $opts{scalefactor} in scale(), give it a scalar to call it's own.
check $Config{ldflags} and $Config{ccflags} for places to search for headers and libraries. This deals with the way the fink build of perl puts -L/sw/lib in ldflags rather than using loclibpth
eliminate some of the duplication of -I and -L options in LIBS and INC
Makefile.PL now uses strict.
the search for freetype1.x headers is now smarter
add tests for scaleX()/scaleY()
expand documentation of scaleX()/scaleY()
rotate()s back parameter now accepts color names like other methods
convert t/t69rubthru.t to Test::More
minor clean up of rubthrough() method
error handling tests for rubthrough()
expand Imager::Transformations:
- document parameters more explicitly
- document return values
- add examples
- add AUTHOR, SEE ALSO, REVISION
eliminate sign warning from image.c
make TIFF detection stricter
more memory allocation integer overflow auditing
IM_DEBUG_MALLOC wasn't interacting well with the API
make win32.c const happy
make raw.c C89 compliant
added version/level to the API function table structure
fix/simplify META.yml generation - we now generate META.yml at Makefile.PL time, since trying to work with EU::MM to generate a custom META.yml was a waste.
bump to 0.47_01
