17==============
18
19Development release as a sanity check for the types re-work.
8d14daab
TC
20
21Massive types re-work:
22
23 - the type used internally for pixel co-ordinates and image sizes is
24 now 64-bit on 64-bit platforms (at least sane ones).
25
26 - size_t is now used consistently for memory block sizes.
27
28 - since this changes the binary interface, the Imager API version has
29 been incremented. Any module that uses the API will need to be
30 rebuilt. In most cases that will be enough, but calls to any APIs
31 that take a pointer to image sizes may need source changes.
32
33 - you should be able to create very large images on 64-bit systems,
34 if you have enough memory. Successfully created a 32768 x 49192 x
35 3 channel image, filled with a tiled image and scaled it. The
36 unscaled image was also successfully saved to a JPEG.
37
38 - check the image size before attempting to write BMP, GIF, JPEG,
39 PNG, SGI, TGA, TIFF images.
40
41 - correctly handle reading TGA images over 32767 pixels wide or tall.
42
43Incidental changes:
44
45 - the gif_left and gif_top tags are now clamped to non-negative
46 values when writing a GIF image.
47
48 - removed dead callback read/write code
49
50The default maximum memory size when reading files is now 1G.

55 - Imager no longer inherits from Exporter (unless you're running an
56 old, old perl.
57

TC
58 - Imager can now write progressive JPEGs (it could always read them).

77 - convert colors to grayscale if the supplied (or generated) palette
78 contains only grays when performing error diffusion color
79 translation.
80 https://rt.cpan.org/Ticket/Display.html?id=68508
81
59c150a4
TC
82 - writing a paletted image to GIF wouldn't always use the colors
83 supplied (or generated, eg. via make_colors => "mono"), which was
84 confusing at best.
85 https://rt.cpan.org/Ticket/Display.html?id=67912
86

87 - replace (imager|tony)@imager.perl.org in the doc, since I don't

104
105Bug fixes:

TC
111 - compose() with the target, source or mask position off the top or
112 left of the target image didn't clip the source image correctly.
113 https://rt.cpan.org/Ticket/Display.html?id=67220
114
115 - compose() now returns a useful error message on a non-positive
116 opacity.
117
118 - compose.im now at 100% test coverage. (As opposed to, umm, much,
119 much less.)

TC
122===========
123
124Bug fixes:
125
126 - eliminate calls to i_has_format() from the test suite, since it's
127 no longer a useful way to check for file format support. Eliminate
128 i_has_format() from the functions exposed via XS.
129 https://rt.cpan.org/Ticket/Display.html?id=65863
130
7540f84a
TC
131 - eliminate calls to note(), which isn't in the (very old) version of
132 Test::More we have as a pre-requisite. note() is modern enough
133 that I don't feel a need to require a Test::More upgrade for it.
134 https://rt.cpan.org/Ticket/Display.html?id=65864
135
81984f30

c901f27d
TC
145 - increase the version of Imager::Font::Type1 so that upgrades don't
146 downgrade the version in this file.
147 https://rt.cpan.org/Ticket/Display.html?id=66250
148
149 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
150 that option for the directories that would normally go in
151 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

229 channels are either 0, sourced from a single input channel or 1.
230 This significantly speeds up presets like "addalpha", "green".
231 https://rt.cpan.org/Ticket/Display.html?id=51254

173c91ba 317 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
318 used for color translation on Unix-like systems, and the fix
319 improves performance of supplying colors by name by about 80 times.
320 Test code that managed 3400 10x10 pixel boxes/second sped up to
321 25700 boxes/second.

374 - added the ability to read multiple-image PNM files.
375 Note that unlike the pbm/pgm/ppm specification this accepts mixed

495 - the conv filter now enforces that the sum of the coefficients is
496 non-zero. Also, rather than skipping pixels off the edge off the
497 edge of the image, the closest edge pixel is used. Previously
498 dividing by the zero sum of coefficients could cause invalid
499 results or runtime exceptions.

686This release primarily contains changes to improve ease of use -
687rather than you having to convert images to the appropriate number of

695 - moved the imtoc.perl code into Imager::Preprocess

697 - paste() and rubthrough() now adapt the source image data to the
698 destination, so you can now safely paste/rubthrough from greyscale
699 images to color images or back, or from alpha channel images to
700 noalpha channels or back.
701 https://rt.cpan.org/Ticket/Display.html?id=30908
702
703 - rubthrough() now falls back to pasting when the source doesn't have
704 an alpha channel. This effectively treats the source as having a
705 max alpha channel, the right thing to do.
706 http://rt.cpan.org/Ticket/Display.html?id=29944
707
708 - re-worked most of the area filling code to use a common set of
709 functions when filling.
710 Corrected normal combine mode.
711 Rewrote most of the combine modes to match the way the SVG draft
712 defines them with respect to a translucent source and destination.

754 - handling of the left-over bit for 16-bit/pixel TGA images has been
755 changed to match the behaviour of the GIMP. Previously the bit
756 being set was treated as an opaque pixel, but one user reported a
757 problem with loading such an image. I haven't been able to find any
758 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
759 I'll match it's behaviour. See issue 114913 in the GIMP's

917 - the mask for ICO/CUR images is now applied as an alpha channel to
918 the returned image. For the old behaviour, supply ico_masked => 0
919 to read() or read_multi(). This should be less confusing when
920 using Imager as a general image processor.

923Bug fixes:
924
925 - in some cases it's possible for giflib/libungif to return color
926 indexes outside the range of colors defined by the image's palette.
927 We now expand the palette to match the indexes used.
928 Thanks to Gabriel Vasseur for reporting this.

933 - to avoid confusion, channels not present in the image are returned as
934 zero by getscanline(). This has no effect on the C level i_glin()
935 and i_glinf() API functions which continue to not set the unused
936 channels.

1078Imager 0.55 - 16 Dec 2006
1079===========
1080
1081This is primarily a bug fix release.
1082
1083Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1084
1085There is one new feature:
1086
1087 - the Win32 font driver now supports UTF8 (RT 22166)
1088 http://www.cpanforum.com/threads/3276
1089 http://rt.cpan.org/Ticket/Display.html?id=22166
1090
1091Several bugs were fixed:
1092
1093 - the string() method would not output the string "0"
1094 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1095
1096 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1097 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1098
1099 - the gif_disposal and gif_user_input tags weren't being read from
1100 the file correctly
1101 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1102
1103 - gif.c was failing to build under MSVC
1104 http://rt.cpan.org/Ticket/Display.html?id=23922
1105
1106 - in some cases strings passed to the string() method were treated as
1107 terminated by NUL (chr 0)
1108 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1109
1110 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1111 that's the default build name for zlib on Win32.
1112 http://rt.cpan.org/Ticket/Display.html?id=23064
1113
1114 - search $Config{incpath} for headers too, which we should have been
1115 doing all along.
1116
1117Win32 font driver fixes:
1118
1119 - the global descent value from bounding box was the wrong sign
1120 http://www.cpanforum.com/threads/3276
1121
1122 - if the first or last glyph overflowed the left or right side of the
1123 advance width they would be clipped
1124
1125
1126Imager 0.54 - 14 Sep 2006
1127===========
1128
1129This is primarily a feature release:
1130
1131 - a new qtype value 'mixing' has been added to the scale()
1132 method. This is faster than 'normal', slower than 'preview'. This
1133 is based on the method used by pnmscale, and seems to produce less
1134 blurry results than normal.
1135 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1136
1137 - the rubthrough() method can now render onto images with an alpha
1138 channel.
1139 http://rt.cpan.org/Ticket/Display.html?id=20678
1140
1141 - the read_multi() method now falls back to calling doing a single
1142 image read via the read() method and write_multi() will now fall
1143 back to calling write() if a single image is supplied. This means
1144 you can simply call the read_multi() or write_multi() functions
1145 without having to check if the type is formatted by that method.
1146 http://rt.cpan.org/Ticket/Display.html?id=19457
1147 http://rt.cpan.org/Ticket/Display.html?id=19458
1148
1149 - the GIF loop extension can now be written. If you don't have
1150 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1151 should upgrade.
1152 http://rt.cpan.org/Ticket/Display.html?id=21185
1153
1154 - getscanline() and setscanline() can now read/write palette index
1155 based data from/to the image for paletted images, by setting type to
1156 'index'.
1157 http://rt.cpan.org/Ticket/Display.html?id=20338
1158
1159 - we no longer hassle you to disable GIF support
1160 http://rt.cpan.org/Ticket/Display.html?id=20687
1161
1162 - minor documentation fixes
1163
1164
1165Imager 0.53 - 26 Jul 2006
1166===========
1167
1168This is a bugfix release.
1169
1170Some test code was left in a code path not covered by the test
1171suite. A test was added to cover this code path and the test code was
1172removed.
1173http://rt.cpan.org/Public/Bug/Display.html?id=20705
1174
1175
1176Imager 0.52 - 25 Jul 2006
1177===========
1178
1179This is primarily a feature release, but contains a fair few bug
1180fixes, new features:
1181
1182 - ability to read and write MS Windows ICO and CUR files
1183
1184 - you can now add file format plugins to support new file formats
1185
1186 - add POD coverage tests
1187
1188 - setcolors() and addcolors() now accept color names and so on
1189 instead of requiring Imager::Color objects.
1190 http://rt.cpan.org/Ticket/Display.html?id=20056
1191
1192 - flood_fill() can now fill to a specified border color instead of
1193 just to the area the same color as the seed.
1194 http://rt.cpan.org/Ticket/Display.html?id=19618
1195
1196
1197Bug fixes:
1198
1199 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1200 calculating the advance width.
1201 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1202
1203 - bounding_box for the T1 driver wasn't including leading and
1204 trailing spaces in the bounding box as the other drivers did, it also
1205 produced strange results for empty strings or strings containing only
1206 spaces
1207
1208 - when reading CMYK jpeg images they were being transferred to the
1209 image object as is, producing a four channel image. It only looked ok
1210 due to an old still unfixed Photoshop bug. We now convert from the
1211 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1212 http://rt.cpan.org/Ticket/Display.html?id=20416
1213
1214 - reading a CYMK TIFF would result in a 4 channel image, reading any
1215 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1216 result in an error.
1217 http://rt.cpan.org/Ticket/Display.html?id=20415
1218
1219 - added /usr/local/include to the default include search path, since
1220 we were already searching /usr/local/lib for libraries.
1221
1222And various minor fixes and documentation updates.
1223
1224
1225Imager 0.51 - 23 Apr 2006
1226===========

1229 a crash
1230 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1231
1232 - fix mis-processing of the src_maxx and src_maxy parameters of the

1242===========
1243

1245 or 4 channel image to jpeg or a 2 channel image to tga where the
1246 output is an in-memeory buffer.

1248
1249 - fixes an incorrect pointer parameter in the PNG code
1250 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1251
