6Bug fixes:
7
8 - the image file limits set by set_file_limits() weren't being
9 checked when reading TIFF files.

11
5970bd39
TC
12 - Provide more information about file format module load errors on a
13 failed image file read() or write().
14 https://rt.cpan.org/Ticket/Display.html?id=69194
15
4ce3551c
TC
16 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
17 through TIFF images, since it checks for IFD loops.
18 https://rt.cpan.org/Ticket/Display.html?id=69914
19
a16bca6d
TC
20 - don't leak memory when out of range palette indexes are supplied to
21 setscanline().
22 https://rt.cpan.org/Ticket/Display.html?id=69242
23
24 - require a later version of CPAN::Meta to ensure JSON::PP and
25 CPAN::Meta::YAML are available.
26 https://rt.cpan.org/Ticket/Display.html?id=69008
27
ac575c5f
TC
28 - hoist the per-line calculations for the flines implementations, and
29 modernize the tests a bit.
30 https://rt.cpan.org/Ticket/Display.html?id=70126
31
86c8d19a
TC
32 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
33 them when available.
34 https://rt.cpan.org/Ticket/Display.html?id=69147
35
a3fd7df7
TC
36 - if t1lib failed to reinitialize it would be left as marked
37 initialized.

43Imager 0.84_01 - 8 Aug 2011
44==============
45
46Development release as a sanity check for the types re-work.
8d14daab
TC
47
48Massive types re-work:
49
50 - the type used internally for pixel co-ordinates and image sizes is
51 now 64-bit on 64-bit platforms (at least sane ones).
52
53 - size_t is now used consistently for memory block sizes.
54
55 - since this changes the binary interface, the Imager API version has
56 been incremented. Any module that uses the API will need to be
57 rebuilt. In most cases that will be enough, but calls to any APIs
58 that take a pointer to image sizes may need source changes.
59
60 - you should be able to create very large images on 64-bit systems,
61 if you have enough memory. Successfully created a 32768 x 49192 x
62 3 channel image, filled with a tiled image and scaled it. The
63 unscaled image was also successfully saved to a JPEG.
64
65 - check the image size before attempting to write BMP, GIF, JPEG,
66 PNG, SGI, TGA, TIFF images.
67
68 - correctly handle reading TGA images over 32767 pixels wide or tall.
69
70Incidental changes:
71
72 - the gif_left and gif_top tags are now clamped to non-negative
73 values when writing a GIF image.
74
75 - removed dead callback read/write code
76
77The default maximum memory size when reading files is now 1G.
78

b1e66a82
TC
80===========
81
82 - Imager no longer inherits from Exporter (unless you're running an
83 old, old perl.
84
92e9df65
TC
85 - Imager can now write progressive JPEGs (it could always read them).

TC
88Bug fixes:
89

102 https://rt.cpan.org/Ticket/Display.html?id=65228
103
6d068d36
TC
104 - convert colors to grayscale if the supplied (or generated) palette
105 contains only grays when performing error diffusion color
106 translation.
107 https://rt.cpan.org/Ticket/Display.html?id=68508
108
59c150a4
TC
109 - writing a paletted image to GIF wouldn't always use the colors
110 supplied (or generated, eg. via make_colors => "mono"), which was
111 confusing at best.
112 https://rt.cpan.org/Ticket/Display.html?id=67912
113
5b480b14
TC
114 - replace (imager|tony)@imager.perl.org in the doc, since I don't
115 plan to continue receiving mail at that address.

130Dev release, in case the compose tests are too sensitive.
deb1a916
TC
131
132Bug fixes:
133
134 - Imager::Font::T1 incorrectly checked for absolute filename under
135 Win32. Thanks to kmx for the report and fix.
136 https://rt.cpan.org/Ticket/Display.html?id=67963
137
618a3282
TC
138 - compose() with the target, source or mask position off the top or
139 left of the target image didn't clip the source image correctly.
140 https://rt.cpan.org/Ticket/Display.html?id=67220
141
142 - compose() now returns a useful error message on a non-positive
143 opacity.
144
145 - compose.im now at 100% test coverage. (As opposed to, umm, much,
146 much less.)

2368cfec
TC
149===========
150
151Bug fixes:
152
153 - eliminate calls to i_has_format() from the test suite, since it's
154 no longer a useful way to check for file format support. Eliminate
155 i_has_format() from the functions exposed via XS.
156 https://rt.cpan.org/Ticket/Display.html?id=65863
157
7540f84a
TC
158 - eliminate calls to note(), which isn't in the (very old) version of
159 Test::More we have as a pre-requisite. note() is modern enough
160 that I don't feel a need to require a Test::More upgrade for it.
161 https://rt.cpan.org/Ticket/Display.html?id=65864
162
81984f30
TC
163 - skip the threads tests on Test::More 2.00_*

170 https://rt.cpan.org/Ticket/Display.html?id=9675
171
c901f27d
TC
172 - increase the version of Imager::Font::Type1 so that upgrades don't
173 downgrade the version in this file.
174 https://rt.cpan.org/Ticket/Display.html?id=66250
175
176 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
177 that option for the directories that would normally go in
178 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

254
2a2c791f
TC
255 - the convert() method now optimizes the case where all output
256 channels are either 0, sourced from a single input channel or 1.
257 This significantly speeds up presets like "addalpha", "green".
258 https://rt.cpan.org/Ticket/Display.html?id=51254

173c91ba 344 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
345 used for color translation on Unix-like systems, and the fix
346 improves performance of supplying colors by name by about 80 times.
347 Test code that managed 3400 10x10 pixel boxes/second sped up to
348 25700 boxes/second.

a596d4f6
TC
401 - added the ability to read multiple-image PNM files.
402 Note that unlike the pbm/pgm/ppm specification this accepts mixed

404 Thanks to Philip Gwyn (Leolo) for this patch.
405
1d7e3124
TC
406 - moved the PNG file handling code into a sub-module in preparation

727 noalpha channels or back.
728 https://rt.cpan.org/Ticket/Display.html?id=30908
729
730 - rubthrough() now falls back to pasting when the source doesn't have
731 an alpha channel. This effectively treats the source as having a
732 max alpha channel, the right thing to do.
733 http://rt.cpan.org/Ticket/Display.html?id=29944
734
735 - re-worked most of the area filling code to use a common set of

739 defines them with respect to a translucent source and destination.

784 problem with loading such an image. I haven't been able to find any
785 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
786 I'll match it's behaviour. See issue 114913 in the GIMP's

944 - the mask for ICO/CUR images is now applied as an alpha channel to
945 the returned image. For the old behaviour, supply ico_masked => 0

1105Imager 0.55 - 16 Dec 2006
1106===========
1107
1108This is primarily a bug fix release.
1109
1110Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1111
1112There is one new feature:
1113
1114 - the Win32 font driver now supports UTF8 (RT 22166)
1115 http://www.cpanforum.com/threads/3276
1116 http://rt.cpan.org/Ticket/Display.html?id=22166
1117
1118Several bugs were fixed:
1119
1120 - the string() method would not output the string "0"
1121 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1122
1123 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1124 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1125
1126 - the gif_disposal and gif_user_input tags weren't being read from
1127 the file correctly
1128 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1129
1130 - gif.c was failing to build under MSVC
1131 http://rt.cpan.org/Ticket/Display.html?id=23922
1132
1133 - in some cases strings passed to the string() method were treated as
1134 terminated by NUL (chr 0)
1135 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1136
1137 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1138 that's the default build name for zlib on Win32.
1139 http://rt.cpan.org/Ticket/Display.html?id=23064
1140
1141 - search $Config{incpath} for headers too, which we should have been
1142 doing all along.
1143
1144Win32 font driver fixes:
1145
1146 - the global descent value from bounding box was the wrong sign
1147 http://www.cpanforum.com/threads/3276
1148
1149 - if the first or last glyph overflowed the left or right side of the
1150 advance width they would be clipped
1151
1152
1153Imager 0.54 - 14 Sep 2006
1154===========
1155
1156This is primarily a feature release:
1157
1158 - a new qtype value 'mixing' has been added to the scale()
1159 method. This is faster than 'normal', slower than 'preview'. This
1160 is based on the method used by pnmscale, and seems to produce less
1161 blurry results than normal.
1162 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1163
1164 - the rubthrough() method can now render onto images with an alpha
1165 channel.
1166 http://rt.cpan.org/Ticket/Display.html?id=20678
1167
1168 - the read_multi() method now falls back to calling doing a single
1169 image read via the read() method and write_multi() will now fall
1170 back to calling write() if a single image is supplied. This means
1171 you can simply call the read_multi() or write_multi() functions
1172 without having to check if the type is formatted by that method.
1173 http://rt.cpan.org/Ticket/Display.html?id=19457
1174 http://rt.cpan.org/Ticket/Display.html?id=19458
1175
1176 - the GIF loop extension can now be written. If you don't have
1177 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1178 should upgrade.
1179 http://rt.cpan.org/Ticket/Display.html?id=21185
1180
1181 - getscanline() and setscanline() can now read/write palette index
1182 based data from/to the image for paletted images, by setting type to
1183 'index'.
1184 http://rt.cpan.org/Ticket/Display.html?id=20338
1185
1186 - we no longer hassle you to disable GIF support
1187 http://rt.cpan.org/Ticket/Display.html?id=20687
1188
1189 - minor documentation fixes
1190
1191
1192Imager 0.53 - 26 Jul 2006
1193===========
1194
1195This is a bugfix release.
1196
1197Some test code was left in a code path not covered by the test
1198suite. A test was added to cover this code path and the test code was
1199removed.

1202
1203Imager 0.52 - 25 Jul 2006
1204===========
1205
1206This is primarily a feature release, but contains a fair few bug
1207fixes, new features:
1208
1209 - ability to read and write MS Windows ICO and CUR files
1210
1211 - you can now add file format plugins to support new file formats
1212
1213 - add POD coverage tests
1214
1215 - setcolors() and addcolors() now accept color names and so on
1216 instead of requiring Imager::Color objects.
1217 http://rt.cpan.org/Ticket/Display.html?id=20056
1218
1219 - flood_fill() can now fill to a specified border color instead of
1220 just to the area the same color as the seed.
1221 http://rt.cpan.org/Ticket/Display.html?id=19618
1222
1223
1224Bug fixes:
1225
1226 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1227 calculating the advance width.
1228 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1229
1230 - bounding_box for the T1 driver wasn't including leading and
1231 trailing spaces in the bounding box as the other drivers did, it also
1232 produced strange results for empty strings or strings containing only
1233 spaces
1234
1235 - when reading CMYK jpeg images they were being transferred to the
1236 image object as is, producing a four channel image. It only looked ok
1237 due to an old still unfixed Photoshop bug. We now convert from the
1238 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1239 http://rt.cpan.org/Ticket/Display.html?id=20416
1240
1241 - reading a CYMK TIFF would result in a 4 channel image, reading any
1242 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1243 result in an error.
1244 http://rt.cpan.org/Ticket/Display.html?id=20415
1245
1246 - added /usr/local/include to the default include search path, since
1247 we were already searching /usr/local/lib for libraries.
1248
1249And various minor fixes and documentation updates.
1250
1251
1252Imager 0.51 - 23 Apr 2006
