28 version 1.4.0 [January 3, 2010] |
42 Changes since the last public release (1.2.39): |
29 |
43 |
30 Enabled iTXt support (changes png_struct, thus requires so-number change). |
44 version 1.2.40 [September 10, 2009] |
31 Cleaned up PNG_ASSEMBLER_CODE_SUPPORTED vs PNG_MMX_CODE_SUPPORTED |
45 |
32 Eliminated PNG_1_0_X and PNG_1_2_X macros. |
46 Removed an extra png_debug() recently added to png_write_find_filter(). |
33 Removed deprecated functions png_read_init, png_write_init, png_info_init, |
47 Fixed incorrect #ifdef in pngset.c regarding unknown chunk support. |
34 png_permit_empty_plte, png_set_gray_1_2_4_to_8, and removed the |

|
43 writing an embedded PNG without the 8-byte signature. |
|
44 Updated scripts/pngos2.def, pngw32.def, and projects/wince/png32ce.def |
|
45 Added PNG_NO_GET_INT_32 and PNG_NO_SAVE_INT_32 macros. |
|
46 Scripts/libpng.pc.in contained "configure" style version info and would |
|
47 not work with makefiles. |
|
48 Increased sprintf buffer from 50 to 52 chars in pngrutil.c to avoid |
|
49 buffer overflow. |
|
50 Fixed bug in example.c (png_set_palette_rgb -> png_set_palette_to_rgb)) |
|
51 Changed sonum from 0 to 1. |
|
52 Removed unused prototype for png_check_sig() from png.h |
|
53 Prepended "#! /bin/sh" to ltmail.sh and contrib/pngminus/*.sh (Cosmin). |
|
54 Avoided potential buffer overflow and optimized buffer in |
|
55 png_write_sCAL(), png_write_sCAL_s() (Cosmin). |

|
65 Added png_set_benign_errors(), png_benign_error(), png_chunk_benign_error(). |
|
66 Revised INSTALL and autogen.sh |
|
67 Fixed typo in several makefiles (-W1 should be -Wl) |
|
68 Added typedef for png_int_32 and png_uint_32 on 64-bit systems. |
|
69 Added one zero element to png_gamma_shift[] array in pngrtran.c to avoid |

|
72 public sTER chunk and a private vpAg chunk. |
|

|
83 operation (Cosmin). |
|
84 Implemented support for I/O states. Added png_ptr member io_state, and |
|
85 functions png_get_io_chunk_name() and png_get_io_state() in pngget.c |
|
86 (Cosmin). |

|
96 Removed PNG_TYPECAST_NULL and used standard NULL consistently (Cosmin). |
|
97 Disallowed the user to redefine png_size_t, and enforced a consistent use |
|
98 of png_size_t across libpng (Cosmin). |
|
99 Changed the type of png_ptr->rowbytes, PNG_ROWBYTES() and friends |
|
100 to png_size_t (Cosmin). |
|
101 Removed png_convert_size() and replaced png_sizeof with sizeof (Cosmin). |
|
102 Removed some unnecessary type casts (Cosmin). |
|
103 Changed prototype of png_get_compression_buffer_size() and |
|
104 png_set_compression_buffer_size() to work with png_size_t instead of |
|
105 png_uint_32 (Cosmin). |
|
106 Removed png_memcpy_check() and png_memset_check() (Cosmin). |
|
107 Fixed a typo (png_byte --> png_bytep) in libpng.3 and libpng.txt (Cosmin). |
|
108 Clarified that png_zalloc() does not clear the allocated memory, |
|
109 and png_zalloc() and png_zfree() cannot be PNGAPI (Cosmin). |
|
110 Renamed png_mem_size_t to png_alloc_size_t, fixed its definition in |
|
111 pngconf.h, and used it in all memory allocation functions (Cosmin). |
|
112 Renamed pngintrn.h to pngpriv.h, added a comment at the top of the file |
|
113 mentioning that the symbols declared in that file are private, and |
|
114 updated the scripts and the Visual C++ projects accordingly (Cosmin). |
|
115 Removing trailing '.' from the warning and error messages (Cosmin). |
|
116 Revised many of the makefiles to write their defines in pngdefs.h. |
|
117 Changed "logical" to "bitwise" in the documentation. |
|
118 Work around Intel-Mac compiler bug by setting PNG_NO_MMX_CODE in pngconf.h |
|
119 Add a typecast to stifle compiler warning in pngrutil.c |

|
127 Changed "new_key[79] = '\0';" to "(*new_key)[79] = '\0';" in pngwutil.c |
|

|
129 Added scripts/CMakeLists.txt |
|
130 Added "png_ptr->num_trans=0" before error return in png_handle_tRNS, |
|
131 to eliminate a vulnerability (CVE-2007-2554, CERT VU#684664) |
|
132 Added png_ptr->unknown_chunk to hold working unknown chunk data, so it |
|
133 can be free'ed in case of error. Revised unknown chunk handling in |
|
134 pngrutil.c and pngpread.c to use this structure. |
|
135 Prefer PNG_USE_PNGVCRD when _MSC_VER is defined in pngconf.h |
|
136 Revised pngvcrd.c for improved efficiency. |
|
137 Moved local array "chunkdata" from pngrutil.c to the png_struct, so |
|
138 it will be freed by png_read_destroy() in case of a read error (Kurt |
|
139 Christensen). |
|
140 Change "purpose" and "buffer" to png_ptr->chunkdata to avoid memory leaking. |
|
141 Change all "chunkdata" to "png_ptr->chunkdata" in png_decompress_chunk(), |
|
142 and remove "chunkdata" from parameter list. |

|
154 Added PNG_LITERAL_CHARACTER macros for #, [, and ]. |
|
155 Moved newline character from individual png_debug messages into the |
|
156 png_debug macros. |
|
157 Allow user to #define their own png_debug, png_debug1, and png_debug2. |
|
158 Added PNG_STRING_NEWLINE macro |
|
159 Added PNG_STRING_COPYRIGHT macro. |
|
160 Added non-ISO versions of png_debug macros. |

|
162 blocks around new png_flush() call. |
|
163 Revised PNG_NO_STDIO version of png_write_flush() |
|
164 Added png_get|set_chunk_cache_max() to limit the total number of sPLT, |
|
165 text, and unknown chunks that can be stored. |
|
166 Shortened tIME_string to 29 bytes in pngtest.c |
|
167 Revised makefile.darwin to fix shared library numbering. |
|
168 Change png_set_gray_1_2_4_to_8() to png_set_expand_gray_1_2_4_to_8() |
|
169 in example.c (debian bug report) |
|
170 Sync with tEXt vulnerability fix in libpng-1.2.33rc02. |
|
171 Added png_check_cHRM in png.c and moved checking from pngget.c, pngrutil.c, |
|
172 and pngwrite.c |
|
173 Added check for zero-area RGB cHRM triange in png_check_cHRM() and |
|
174 png_check_cHRM_fixed(). |
|
175 Revised png_warning() to write its message on standard output by default |
|
176 when warning_fn is NULL. |
|
177 Eliminated png_check_cHRM(). Instead, always use png_check_cHRM_fixed(). |
|
178 In png_check_cHRM_fixed(), ensure white_y is > 0, and removed redundant |
|
179 check for all-zero coordinates that is detected by the triangle check. |
|
180 Rearranged test expressions in png_check_cHRM_fixed() to avoid internal |
|
181 overflows. |
|
182 Added PNG_NO_CHECK_cHRM conditional. |
|
183 Fixed string vs pointer-to-string error in png_check_keyword(). |
|
184 Added PNG_NO_CHECK_cHRM conditional. |
|
185 Merge png_debug with version 1.2.34beta04. |
|
186 Removed redundant check for key==NULL before calling png_check_keyword() |
|
187 to ensure that new_key gets initialized and removed extra warning |
|
188 (Merge with version 1.2.34beta05 -- Arvan Pritchard). |
|
189 Added PNG_TRANSFORM_STRIP_FILLER_BEFORE and PNG_TRANSFORM_STRIP_FILLER_AFTER |
|
190 conditionals and deprecated PNG_TRANSFORM_STRIP_FILLER (Jim Barry). |
|
191 Turned off PNG_READ_DITHER_SUPPORTED by default. |
|
192 Combined several instances of png_malloc(); png_memset() into png_calloc(). |
|
193 Fixed order of #ifdef directives in the png_debug defines in png.h |
|
194 (bug introduced in libpng-1.2.34). |
|
195 Revised comments in png_set_read_fn() and png_set_write_fn(). |
|
196 Use png_calloc() instead of png_malloc() to allocate big_row_buf when |
|
197 reading an interlaced file, to avoid a possible UMR. |
|
198 Revised libpng*.txt and png.h documentation about use of png_write_flush() |
|
199 and png_set_write_fn(). |
|
200 Removed fflush() from pngtest.c. |

|
205 Fixed potential memory leak of "new_name" in png_write_iCCP() (Ralph Giles) |
|
206 Added "ifndef PNG_SKIP_SETJMP_CHECK" block in pngconf.h to allow |
|
207 application code writers to bypass the check for multiple inclusion |
|
208 of setjmp.h when they know that it is safe to ignore the situation. |
|
209 Eliminated internal use of setjmp() in pngread.c and pngwrite.c |
|
210 Eliminated deprecated png_read_init_3() and png_write_init_3() functions. |
|
211 Renamed "user_chunk_data" to "my_user_chunk_data" in pngtest.c to suppress |
|
212 "shadowed declaration" warning from gcc-4.3.3. |
|
213 Renamed "gamma" to "png_gamma" in pngset.c to avoid "shadowed declaration" |
|
214 warning about a global "gamma" variable in math.h on some platforms. |
|
215 Removed pngprefs.h and MMX from makefiles |
|
216 Rebuilt configure scripts with autoconf-2.63 instead of 2.62 |

|
218 Reformated sources in libpng style (3-space intentation, comment format) |
|
219 Fixed typo in libpng docs (PNG_FILTER_AVE should be PNG_FILTER_AVG) |
|
220 Added sections about the git repository and our coding style to the |
|
221 documentation |
|
222 Relocated misplaced #endif in pngwrite.c, sCAL chunk handler. |
|
223 Conditionally compile png_read_finish_row() which is not used by |
|
224 progressive readers. |
|
225 Added contrib/pngminim/preader to demonstrate building minimal progressive |
|
226 decoder, based on contrib/gregbook with embedded libpng and zlib. |
|
227 In contrib/pngminim/*, renamed "makefile.std" to "makefile", since there |
|
228 is only one makefile in those directories, and revised the README files |
|
229 accordingly. |
|
230 Added "#define PNG_NO_WRITE_SWAP" to contrib/pngminim/encoder/pngusr.h |
|
231 and "define PNG_NO_READ_SWAP" to decoder/pngusr.h and preader/pngusr.h |
|
232 Added a section in the documentation about using png_get_io_ptr() in |
|
233 configure scripts to detect the presence of libpng. |
|
234 Revised libpng*.txt and libpng.3 to mention calling png_set_IHDR() |
|
235 multiple times and to specify the sample order in the tRNS chunk, |
|
236 because the ISO PNG specification has a typo in the tRNS table. |
|
237 Changed several PNG_UNKNOWN_CHUNK_SUPPORTED to |
|
238 PNG_HANDLE_AS_UNKNOWN_SUPPORTED, to make the png_set_keep mechanism |
|
239 available for ignoring known chunks even when not saving unknown chunks. |
|
240 Adopted preference for consistent use of "#ifdef" and "#ifndef" versus |
|
241 "#if defined()" and "if !defined()" where possible. |

244 PNG_READ|WRITE_ANCILLARY_CHUNK_SUPPORTED blocks. |
|
245 Added a reference to the libpng license in each file. |
|

247 Added high-level API transform PNG_TRANSFORM_GRAY_TO_RGB. |
|
248 Added an "xcode" project to the projects directory (Alam Arias). |
|
249 Avoid some tests in filter selection in pngwutil.c |
|
250 Avoid a possible NULL dereference in debug build, in png_set_text_2(). |
|
251 (bug introduced in libpng-0.95, discovered by Evan Rouault) |
|
252 Rebuilt configure scripts with autoconf-2.65 |
|
253 Replaced *.tar.lzma with *.tar.xz in distribution. Get the xz codec |

254 from <http://tukaani.org/xz>. |
|
255 Reject attempt to write iCCP chunk with negative embedded profile length |
|
256 (JD Chen) |

258 Removed lpXYZ.tar.bz2 (with CRLF), KNOWNBUG, libpng-x.y.z-KNOWNBUG.txt, |
|
259 and the "noconfig" files from the distribution. |
|

262 Converted all PNG_NO_* tests to PNG_*_SUPPORTED everywhere except pngconf.h |
|
263 Eliminated PNG_NO_FREE_ME and PNG_FREE_ME_SUPPORTED macros. |
|
264 Use png_malloc plus a loop instead of png_calloc() to initialize |
|
265 row_pointers in png_read_png(). |
|
266 Eliminated PNG_GLOBAL_ARRAYS and PNG_LOCAL_ARRAYS; always use local arrays. |
|
267 Eliminated PNG_CALLOC_SUPPORTED macro and always provide png_calloc(). |
|
268 Removed scripts/libpng.icc |
|
269 Changed typecast of filler from png_byte to png_uint_16 in png_set_filler(). |
|
270 (Dennis Gustafsson) |

271 Eliminated unused PNG_FLAG_FREE_* defines from pngpriv.h |
|
272 Expanded TAB characters in pngrtran.c |
|
273 Removed PNG_CONST from all "PNG_CONST PNG_CHNK" declarations to avoid |
|
274 compiler complaints about doubly declaring things "const". |

275 Eliminated unused png_ptr->row_buf_size |
|
276 Changed all "#if [!]defined(X)" to "if[n]def X" where possible. |
|
277 Moved redundant IHDR checking into new png_check_IHDR() in png.c |

278 and report all errors found in the IHDR data. |
|
279 Eliminated useless call to png_check_cHRM() from pngset.c |
|
280 Eliminated a shadowed declaration of "pp" in png_handle_sPLT(). |
|
281 Patched ltmain.sh for wince support. |
|
282 Added PNG_CONVERT_tIME_SUPPORTED macro. |
|
283 Make inclusion of time.h in pngconf.h depend on PNG_CONVERT_tIME_SUPPORTED |

286 Copied projects/wince/png32ce.def to the scripts directory. |
|
287 Added scripts/makefile.cegcc |
|
288 Revised libpng*.txt to describe differences from 1.2.40 to 1.4.0 |
|
289 Added PNG_DEPSTRUCT, PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN, and |
|
290 PNG_ALLOCATED macros to detect deprecated direct access to the |
|
291 png_struct or info_struct members and other deprecated usage in |
|
292 applications (John Bowler). |
|
293 Updated scripts/makefile* to add "-DPNG_CONFIGURE_LIBPNG" to CFLAGS, |
|
294 to prevent warnings about direct access to png structs by libpng |
|
295 functions while building libpng. They need to be tested, especially |
|
296 those using compilers other than gcc. |
|
297 Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions. |
|
298 Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG". |
|
299 They should work but still need to be updated to remove |
|
300 references to pnggccrd.c or pngvcrd.c and ASM building. |
|
301 Added README.txt to the beos, cbuilder5, netware, and xcode projects warning |
|
302 that they need to be updated, to remove references to pnggccrd.c and |
|
303 pngvcrd.c and to depend on pngpriv.h |
|
304 Removed three direct references to read_info_ptr members in pngtest.c |
|
305 that were detected by the new PNG_DEPSTRUCT macro. |
|
306 Moved the png_debug macro definitions and the png_read_destroy(), |
|
307 png_write_destroy() and png_far_to_near() prototypes from png.h |
|
308 to pngpriv.h (John Bowler) |
|
309 Moved the synopsis lines for png_read_destroy(), png_write_destroy() |
|
310 png_debug(), png_debug1(), and png_debug2() from libpng.3 to libpngpf.3. |
|
311 Removed the obsolete, unused pnggccrd.c and pngvcrd.c files. |
|
312 Removed dependency of pngtest.o on pngpriv.h in the makefiles. |
|
313 Added -DPNG_CONFIGURE_LIBPNG to contrib/pngminm/*/makefile |
|
314 Changed png_check_sig() to !png_sig_cmp() in contrib programs. |
|
315 Corrected the png_get_IHDR() call in contrib/gregbook/readpng2.c |
|
316 Changed pngminim/*/gather.sh to stop trying to remove pnggccrd.c and pngvcrd.c |
|
317 Added dependency on pngpriv.h in contrib/pngminim/*/makefile |
|
318 Revised Makefile.am to use libpng.sys while building libpng.so |
|
319 so that only PNG_EXPORT functions are exported. |
|
320 Removed the deprecated png_check_sig() function/macro. |
|
321 Removed recently removed function names from scripts/*.def |
|
322 Added PNG_PRIVATE macro definition in pngconf.h for possible future use. |
|
323 Removed projects/beos and netware.txt; no one seems to be supporting them. |
|
324 Moved libpng-config.in and libpng.pc-configure.in out of the scripts |
|
325 directory, to libpng-config.in and libpng.pc.in, respectively, and |
|
326 modified Makefile.am and configure.ac accordingly. Now "configure" |
|
327 needs nothing from the "scripts" directory. |
|
328 Removed ASM builds from projects/visualc6 and projects/visualc71 |
|
329 Removed scripts/makefile.nommx and makefile.vcawin32 |
|
330 Revised CMakeLists.txt to account for new location of libpng-config.in |
|
331 and libpng.pc.in |
|
332 Updated INSTALL to reflect removal and relocation of files. |
|
333 Moved descriptions of makefiles and other scripts out of INSTALL into |
|
334 scripts/README.txt |
|
335 Updated the copyright year in scripts/pngwin.rc from 2006 to 2009. |
|
336 Removed obsolete comments about ASM from projects/visualc71/README_zlib.txt |
|
337 Align row_buf on 16-byte boundary in memory. |
|
338 Make the 'png_jmpbuf' macro expand to a call that records the correct |
|
339 longjmp function as well as returning a pointer to the setjmp |
|
340 jmp_buf buffer, and marked direct access to jmpbuf 'deprecated'. |
|
341 (John Bowler) |
|
342 Changed "/255" to "/255.0" in background calculations to make it clear |
|
343 that the 255 is used as a double. |
|
344 Added "#define PNG_NO_PEDANTIC_WARNINGS" in the libpng source files. |
|
345 Revised scripts/makefile.netbsd, makefile.openbsd, and makefile.sco |
|
346 to put png.h and pngconf.h in $prefix/include, like the other scripts, |
|
347 instead of in $prefix/include/libpng. Also revised makefile.sco |
|
348 to put them in $prefix/include/libpng14 instead of in |
|
349 $prefix/include/libpng/libpng14. |
|
350 Added "bit_depth" parameter to the private png_build_gamma_table() function. |
|
351 Use png_calloc() instead of png_malloc(); png_memset() in pngrutil.c |

|
353 in pngtest.c |
