9713 828 d 0 h dunkaist /programs/develop/libraries/libs-dev/ libimg: Implement more bit depth conversion routines  
9640 853 d 12 h leency / add KMatrix into Appearance app  
9273 914 d 3 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: Avoid SSE pinsrw instruction in blend_mmx.asm

pinsrw can act on MMX registers, but it is still an SSE instruction.		  
8497 1234 d 19 h dunkaist /programs/ kiv and libimg.asm: Follow asm style guide, no semantic changes.  
8463 1243 d 11 h IgorA /programs/develop/libraries/libs-dev/ libimg: can save 32 bit png  
8449 1246 d 3 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: Improve support of transparent PNG images.

* Support grayscale images with alpha channel.
* Support rgb images with transparent color.
* Process 'tRNS' chunk (simple transparency).

Transparent png images were already supported for color type 6, which
is RGBA. Now indexed images (color type 3) can also have transparency
via 'tRNS' chunk data.		  
8408 1250 d 8 h IgorA /programs/ tinygl: add some double functions, add bcc32 example
libimg: small optimize		  
8399 1251 d 3 h dunkaist /programs/develop/libraries/libs-dev/libimg/png/ libimg: fix transparency in indexed png images.  
8395 1251 d 7 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: export img.resize_data  
8394 1251 d 7 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: transparency fixes.

img.convert doesn't make opaque pixels transparent.
gif decoder considers palette pixels opaque.		  
8363 1253 d 22 h leency /programs/ libimg: img.decode now checks that length is not null
WebView: img tag: proceed data-src= if src= is empty, fix crash		  
8341 1256 d 7 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: Add and export img.blend function  
7735 1532 d 12 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: tiff: Don't rely on EOI tag at the end of the strip.

Reference implementation (libtiff) has a workaround: precalculate data
size of the strip and don't rely on EOI tag of specific bit length.

This allow to read some invalid TIFF LZW images by my old scanner.		  
7523 2022 d 7 h dunkaist /programs/develop/libraries/libs-dev/libimg/bmp/ Libimg: Fix bug with 16-bit BMP padding.  
7279 2194 d 8 h IgorA /programs/develop/libraries/libs-dev/libimg/png/ libimg: fix save small png images  
7105 2390 d 3 h dunkaist /programs/develop/libraries/libs-dev/libimg/ libimg: add img.from_file, refactor img.convert.

Add new function, img.from_file: gets file name and returns decoded Image.
Make img.convert code less spaghetti: use jump table, not a chain of jmp's.		  
6891 2575 d 16 h IgorA / update docs sys function 54.1  
6888 2586 d 15 h IgorA /programs/ add filter 'paeth', fix in 'build_bl_tree'  
6883 2598 d 18 h IgorA /programs/ fix continue crc calculation in 'archiver.obj'  
6881 2604 d 6 h IgorA /programs/ small fixes
