- 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.

- 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.

- Makefile.PL step doesn't complain anymore so that is
- hopefully fixed.

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

- - 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.

- - 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.

- - 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.

- 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 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.
+ - 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.

+ 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.

+0.40 TODO list
+ iolayer:
+ - Add scalar/mmap to iolayer
+ - Add close() code to iolayer
+ - Merge callback interface into iolayer
+ - Add interface for writing to all formats but tiff
+ - Add interface for reading for png (started),
+ gif (merge with cb patch), ppm and raw
+ - Add make new tests once all formats support io_layer
+ - Implment the maxread threshold (Indicates how far
+ a library can read before it indicates that it's done).
+
+ MultiImage & metadata support:
+ - Figure what interface should be between C and perl?
+ - How to store data in the C interface for tags/metadata?
+
+ Good stuff:
+ - matrix based colour transformations, for RGB to grayscale
+ and simple linear other conversions, see design/colmatrix.txt
+ - image colour transformations based on input images, see
+ design/cmyktorgb.txt for Addi's description
+ - eventually support tiff's madness
+
+ Old sins:
+ - Make sure everything is doable with the OO interface
+ - Split the other classes into seperate files
+ - Compile with memory debugging enabled and fix leaks
+ - dynaload.c is strongly tied to perl
+
+ - should i_readgif returned colormap be an arrayref of
+ Imager::Color objects? Note that this will break
+ compatibility with previous releases.
+
+ - should Imager::Font be split into a base class whose
+ new chooses a base class (ttf, t1 or win32?) to
+ instantiate. Currently Imager::Font uses if() statements to
+ select between each type of font. It should.
+
+ - should we overload <=> or cmp for Imager::Color objects?
+ too many worms, leave it out
+
+ - if gif_delays is a number instead of an arrayref, use that
+ number for each frame
+
+ - support writing pgm files
+ Documentation:
+ - Add to the documentation
+ - Write a tutorial?
+ - Write a guide to installing the helper libraries
+ - Go through the entire project and add comments in pod
+ so doco.perl can be used to read them.
