2 | ||
bcff4dd9 TC |
3 | Imager 0.60 |
4 | =========== | |
5 | ||
6 | Bug fixes: | |
7 | ||
8 | - in some cases it's possible for giflib/libungif to return color | |
9 | indexes outside the range of colors defined by the image's palette. | |
10 | We now expand the palette to match the indexes used. | |
11 | Thanks to Gabriel Vasseur for reporting this. | |
12 | ||
02576e8d TC |
13 | - fixed various memory leaks that could occur when failing to read png, |
14 | jpeg, bmp or tga files. | |
15 | ||
b3aa972f TC |
16 | - to avoid confusion, channels not present in the image are returned as |
17 | zero by getscanline(). This has no effect on the C level i_glin() | |
18 | and i_glinf() API functions which continue to not set the unused | |
19 | channels. | |

9fc9d0ca TC |
29 | - cropping outside the image would return an Imager object with |
30 | no low-level image object, instead of returning false. | |
31 | Fixed by: Philip Gwyn (Leolo) | |

68 | - reworked library probing, we can now set more than one probe |
69 | function for a library. Disabled the default (non-freetype-config) | |
70 | library probe and added an extra probe function that searches for | |
71 | both ft2build.h and whatever it includes, and adds -I as needed. | |
72 | Hopefully this will fix build problems like | |

96 | - improved performance of reading PBM/PGM/PPM images | |
97 | ||
98 | - added support for writing PBM images if the image is paletted and | |
99 | contains only black and white | |
100 | ||
101 | - added a new make_colors value - "mono" | |
102 | ||
103 | - switched from the svn log Changes to a manual Changes to reduce | |
104 | noise | |
105 | ||
1225d272 TC |
106 | - new sample code - samples/flasher.pl |
107 | ||
7623d340 TC |
108 | Bug fixes: |
109 | ||
110 | - CRITICAL: the "Imager" typemap entry (not used by Imager itself) | |
111 | was returning an image object with an extra reference, this | |
112 | resulted in a memory leak. | |
113 | http://rt.cpan.org/Ticket/Display.html?id=24992 | |
114 | ||
115 | - fix rendering on alpha channel images for the FreeType 2.x driver | |
116 | http://rt.cpan.org/Ticket/Display.html?id=11972 | |
117 | ||
118 | - reading bmp files now consitently handles short reads. You can now | |
119 | supply a parameter to treat a short read as successful and set | |
120 | i_incomplete | |
121 | http://rt.cpan.org/Ticket/Display.html?id=8426 | |
122 | ||
123 | - previously, reading ASCII PBM files required spaces between samples, | |
124 | even though the format doesn't require that | |
125 | ||
1225d272 TC |
126 | - improved documentation of the unsharpmask filter (I hope) |
127 | http://rt.cpan.org/Ticket/Display.html?id=25531 | |
128 | ||
129 | - force flushing of the output from i_tt_dump_names() and test output | |
130 | in t/t35ttfont.t to prevent output from being mixed up. | |
131 | https://rt.cpan.org/Ticket/Display.html?id=24859 | |
132 | ||
133 | - rewrite a conditional expression as an if() to hopefully work around | |
134 | a bug in the pre-4.0 GCC Apple shipped with OS X 10.4. | |
135 | https://rt.cpan.org/Ticket/Display.html?id=25561 | |
136 | ||
137 | - avoid Data::Dumper in regops.perl to support older releases of perl | |

140 | Imager 0.55 - 16 Dec 2006 |
141 | =========== | |
142 | ||
143 | This is primarily a bug fix release. | |
144 | ||
145 | Note: Test::More is now a pre-requisite for Imager and is no longer bundled. | |
146 | ||
147 | There is one new feature: | |
148 | ||
149 | - the Win32 font driver now supports UTF8 (RT 22166) | |
150 | http://www.cpanforum.com/threads/3276 | |
151 | http://rt.cpan.org/Ticket/Display.html?id=22166 | |
152 | ||
153 | Several bugs were fixed: | |
154 | ||
155 | - the string() method would not output the string "0" | |
156 | http://rt.cpan.org/Public/Bug/Display.html?id=21770 | |
157 | ||
158 | - fills.c was failing to compile on Solaris 10 (compiler unknown) | |
159 | http://rt.cpan.org/Public/Bug/Display.html?id=21944 | |
160 | ||
161 | - the gif_disposal and gif_user_input tags weren't being read from | |
162 | the file correctly | |
163 | http://rt.cpan.org/Public/Bug/Display.html?id=22192 | |
164 | ||
165 | - gif.c was failing to build under MSVC | |
166 | http://rt.cpan.org/Ticket/Display.html?id=23922 | |
167 | ||
168 | - in some cases strings passed to the string() method were treated as | |
169 | terminated by NUL (chr 0) | |
170 | http://rt.cpan.org/Public/Bug/Display.html?id=21770 | |
171 | ||
172 | - on "MSWin32" perl builds we now link to -lzlib instead of -lz since | |
173 | that's the default build name for zlib on Win32. | |
174 | http://rt.cpan.org/Ticket/Display.html?id=23064 | |
175 | ||
176 | - search $Config{incpath} for headers too, which we should have been | |
177 | doing all along. | |
178 | ||
179 | Win32 font driver fixes: | |
180 | ||
181 | - the global descent value from bounding box was the wrong sign | |
182 | http://www.cpanforum.com/threads/3276 | |
183 | ||
184 | - if the first or last glyph overflowed the left or right side of the | |
185 | advance width they would be clipped | |
186 | ||
187 | ||
188 | Imager 0.54 - 14 Sep 2006 | |
189 | =========== | |
190 | ||
191 | This is primarily a feature release: | |
192 | ||
193 | - a new qtype value 'mixing' has been added to the scale() | |
194 | method. This is faster than 'normal', slower than 'preview'. This | |
195 | is based on the method used by pnmscale, and seems to produce less | |
196 | blurry results than normal. | |
197 | http://rt.cpan.org/Public/Bug/Display.html?id=20677 | |
198 | ||
199 | - the rubthrough() method can now render onto images with an alpha | |
200 | channel. | |
201 | http://rt.cpan.org/Ticket/Display.html?id=20678 | |
202 | ||
203 | - the read_multi() method now falls back to calling doing a single | |
204 | image read via the read() method and write_multi() will now fall | |
205 | back to calling write() if a single image is supplied. This means | |
206 | you can simply call the read_multi() or write_multi() functions | |
207 | without having to check if the type is formatted by that method. | |
208 | http://rt.cpan.org/Ticket/Display.html?id=19457 | |
209 | http://rt.cpan.org/Ticket/Display.html?id=19458 | |
210 | ||
211 | - the GIF loop extension can now be written. If you don't have | |
212 | libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you | |
213 | should upgrade. | |
214 | http://rt.cpan.org/Ticket/Display.html?id=21185 | |
215 | ||
216 | - getscanline() and setscanline() can now read/write palette index | |
217 | based data from/to the image for paletted images, by setting type to | |
218 | 'index'. | |
219 | http://rt.cpan.org/Ticket/Display.html?id=20338 | |
220 | ||
221 | - we no longer hassle you to disable GIF support | |
222 | http://rt.cpan.org/Ticket/Display.html?id=20687 | |
223 | ||
224 | - minor documentation fixes | |
225 | ||
226 | ||
227 | Imager 0.53 - 26 Jul 2006 | |
228 | =========== | |
229 | ||
230 | This is a bugfix release. | |
231 | ||
232 | Some test code was left in a code path not covered by the test | |
233 | suite. A test was added to cover this code path and the test code was | |
234 | removed. | |
235 | http://rt.cpan.org/Public/Bug/Display.html?id=20705 | |
236 | ||
237 | ||
238 | Imager 0.52 - 25 Jul 2006 | |
239 | =========== | |
240 | ||
241 | This is primarily a feature release, but contains a fair few bug | |
242 | fixes, new features: | |
243 | ||
244 | - ability to read and write MS Windows ICO and CUR files | |
245 | ||
246 | - you can now add file format plugins to support new file formats | |
247 | ||
248 | - add POD coverage tests | |
249 | ||
250 | - setcolors() and addcolors() now accept color names and so on | |
251 | instead of requiring Imager::Color objects. | |
252 | http://rt.cpan.org/Ticket/Display.html?id=20056 | |
253 | ||
254 | - flood_fill() can now fill to a specified border color instead of | |
255 | just to the area the same color as the seed. | |
256 | http://rt.cpan.org/Ticket/Display.html?id=19618 | |
257 | ||
258 | ||
259 | Bug fixes: | |
260 | ||
261 | - bounding_box for the T1 driver wasn't converting UTF8 to ascii when | |
262 | calculating the advance width. | |
263 | http://rt.cpan.org/Public/Bug/Display.html?id=20554 | |
264 | ||
265 | - bounding_box for the T1 driver wasn't including leading and | |
266 | trailing spaces in the bounding box as the other drivers did, it also | |
267 | produced strange results for empty strings or strings containing only | |
268 | spaces | |
269 | ||
270 | - when reading CMYK jpeg images they were being transferred to the | |
271 | image object as is, producing a four channel image. It only looked ok | |
272 | due to an old still unfixed Photoshop bug. We now convert from the | |
273 | inverted CMYK that photoshop (and Corel for example) produce into RGB. | |
274 | http://rt.cpan.org/Ticket/Display.html?id=20416 | |
275 | ||
276 | - reading a CYMK TIFF would result in a 4 channel image, reading any | |
277 | image with more than 4 channels (eg. RGB with 2 alpha channels) would | |
278 | result in an error. | |
279 | http://rt.cpan.org/Ticket/Display.html?id=20415 | |
280 | ||
281 | - added /usr/local/include to the default include search path, since | |
282 | we were already searching /usr/local/lib for libraries. | |
283 | ||
284 | And various minor fixes and documentation updates. | |
285 | ||
286 | ||
287 | Imager 0.51 - 23 Apr 2006 | |
288 | =========== | |
289 | ||
290 | - fix a validation bug when processing JPEG EXIF data that can cause | |
291 | a crash | |
292 | http://rt.cpan.org/Public/Bug/Display.html?id=18496 | |
293 | ||
294 | - fix mis-processing of the src_maxx and src_maxy parameters of the | |
295 | paste() method | |
296 | http://rt.cpan.org/Public/Bug/Display.html?id=18712 | |
297 | ||
298 | - fix a problem in Imager's "smart" handling of the color parameter | |
299 | to various methods. | |
300 | http://rt.cpan.org/Public/Bug/Display.html?id=18561 | |
301 | ||
302 | ||
303 | Imager 0.50 - 29 Mar 2006 | |
304 | =========== | |
305 | ||
306 | - CRITICAL: fixes a segmentation fault from attempting to write a 2 | |
307 | or 4 channel image to jpeg or a 2 channel image to tga where the | |
308 | output is an in-memeory buffer. | |
309 | http://rt.cpan.org/Public/Bug/Display.html?id=18397 | |
310 | ||
311 | - fixes an incorrect pointer parameter in the PNG code | |
312 | http://rt.cpan.org/Public/Bug/Display.html?id=18051 | |
313 | ||
314 | - skip Inline::C tests when building in a directory with spaces | |
315 | http://rt.cpan.org/Public/Bug/Display.html?id=18049 |
