Added new + method icc->read_tag_any() which will return a + icmSigUnknownType if the tag type is unknown. + + 2.14 + Fix potential array bounds violation in icc/icc.c for malformed + cLUT profiles with zero input channels. + + 2.10 + + Added protection against crafted file integer overflows. + + Many minor additions to support ArgyllCMS. + + Further add V4 compatibility, with changes to PCS encoding. + + 2.06 + + Added MD5 checksum code for profile ID support. + + 2.05 + Version in Argyll V0.51 release. + + Started adding support for ICC V4. Not enabled yet. + + Expanded internal/effective colorspace/ranges support + to be uniform between all the lookup types. + + 2.04 + + Fixed minor casting nits picked up by some compilers + (thanks to Keith Trummel). + + Make intent selection for Matrix profiles and Gamut tables + more forgiving if not ICM_STRICT. + + 2.03 + Added simple extention when dumping binary data tag to + dump ASCII as well if verb >= 4. + + Added Makefile support for compiling under MAC OSX. + + Added access to primitive read and write functions, so custom tag + data can be marshalled using standard encodings. + + Expanded ICM_STRICT to encompass bad DateTime information in the header, + and also disable required tag checking on reading or lookups. + Changed default intent for Output profiles to perceptual from + colorimetric, since this would usually be expected. + + Added workaround for faulty Kodak RGB matrix profiles, that + have their primary XYZ coordinates scaled to 100.0 rather than + 1.0. This is enabled if ICM_STRICT is not defined. + + Replaced Lab<->XYZ functions with simpler versions. + + Expand icmFile implimentation to handle icmAlloc + + Do check for header Magic number first. + + Add convenience function that creates an RGB to XYZ transform + matrix from the device primaries and the white point. + + Separated stdio versions of file and alloc to allow + compile without these. + + Non-standard (ie. Apple) 5,6,7 & 8 channel color signatures + weren't being handled properly thruout the library. + + 2.02 + Merged rename of [u]int64 to icm[Ui][I]nt64 (to work around + AIX 5.1L portability bug) from Raph Levien. + + Fixed stray , in icmLookupOrder structure definition (from Dan Coby) + + 2.01 + Change TextDescription code to not barf if #undef ICM_STRICT and + Apple scriptcode not padded to 67 bytes. + + Add get_ranges() method to all Lu types, not just LuLut. + Fix bug in PCS override logic that was causing + reverse conversions to apply the wrong conversion. + + Added Delta E convenience functions icmLabDE() and + icmCIE94() etc. + + Merged Raph Levien's cleanups, to quiet gcc warnings. + + Merged another couple of warning cleanups from Jouk Jansen. + + 2.00 + Change absolute conversion to be white point only, and use + Bradford transform by default. (ie. we are now ignoring the + comment in section 6.4.22 of the 1998 spec. about the + media black point being used for absolute colorimetry, + ignoring the recommendation on page 118 in section E.5, + and are taking up the recommendation on page 124 in section + E.16 that a more sophisticated chromatic adaptation model be used.) + + This is for better compatibility with other CMM's, and to + improve the results when using simple links between + profiles with non-D50 white points. Standard profiles + like sRGB will also be more accurate when interpreted + with absolute colorimetric intent. + This will cause some slight incompatibilty with previous + versions of icclib. + + Added ColorSync 2.5 specific VideoCardGamma tag support + (from Neil Okamoto) + + 1.31 + Added file I/O class to allow substitution of alternative ICC profile + file access. Provide standard file class instance, and memory image + instance of file I/O class as default and example. + Added an optional new_icc_a() object creator, that takes a memory + allocator class instance. This allows an alternate memory heap to + be used with the icc class. + Renamed object free() methods to del() for more consistency with new(). + + 1.30 + Added workaround for reading some Adobe profiles with confused header DateTime. + Enhanced tag allocate() methods so that they can resize allocations. + Enhanced icmLut_set_tables() to access grid points in a cache friendly order. + Fixed bug in check_icc_legal() that caused bogus errors, removed + uneccessary static declarations in icc.h, and fixed a bug in + icmTable_lookup_bwd() that effected both accuracy and speed. (Thanks to Andrei Frolov) + Removed icmAbsoluteColorimetricXYZ intent, and replaced it with + a PCS override capability. This adds a new parameter to get_luobj() + Added Lab translations of some XYZ "dump" strings. + Fix memory leak after failed tag read + rename_tag function + + shared library support changes. (Thanks to Carles Llopis). + Changed all the public 2str utility routines to a single function + that can be used to interpret an enumeration or tag in a human + readable form. + + 1.23 + Fixed important bug in Lut read/write. The matrix values had their + rows and columns switched. Not many profiles exercise this code. + Thanks to David Gillman for discovering this problem. + Fixup compiler complains about illegal enum values for icmCurveStyle, + and icmDataStyle. Malloc memory icmLut_lookup_clut_nl for gw[], so that + it is more friendly to systems with a limited stack. (Thanks to Dave White) + + 1.22 99/11/11 Snapshot of current code. + Added more hooks to support inherited implementation of + color conversion, used in Argyll to support reversing + multi-dimentional table lookups. + Cleaned up color conversion code to make it easier to follow. + Adding simplex interpolation for non-Lab style input space interpolation. + Fix Sun misalignment and realloc problems (Thanks to Allan N. Hessenflow) + Fixed endian problem with Unicode on read and write. + Expanded icmTextDescription_dump() to do hex dump of Unicode and ScriptCode. + Changed over to ICC.1:1998-09 .h file. + Started implementing ICC.1:1998-09, but not complete yet! + + 1.21 99/2/14 + After re-reading Michael Bourgoin's 1998 SIGGRAPH notes, + I have consolidated the Lut input index, and table value encodings. + The default set_tables() scaling has been adjusted appropriately + for this correction of Lab encoding. + Trying to create an 8 bit XYZ Lut will now fail if icclib helper + functions are used to create it. + + 1.20 99/2/7 + Added profile color lookup functon. + Added set_tables() support. + Various bug fixes and enhancements. |
