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 NO TIME YET ** Now in beta10 **
- 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 ****
