BLPConverter - Converts blp files to png files and vice versa.
8.5
- Included with updated version:
- libpng
- zlib
- Applied change from libpng
- Created readme and license file
8.4
- Added support for BLP_RBGAs.
- Expanded return codes. Instead of always -1 on error, now a variety of negative numbers are possible.
8.3
- Added support for reading BLPs of type "Type 1 Encoding 2 AlphaDepth 4 AlphaEncoding 1 (DXT3 four bits alpha)". Note that the program treats them exactly the same as AlphaDepth 8 since there is only one type of DXT3 compression (that I know of).
8.2
- Fixed output filename bug when using wildcards.
8.1
- Added support for BLP_PAL_A4 format.
8.0
- Incorporated David Holland's (david.w.holland@gmail.com) changes no allow for Linux-compatible builds.
- Using squish instead of the ATIlib for DXT compression, as it is cross platform.
7.0
- Textures that have 256 or fewer unique colors now use exactly those colors when palettized.
- Made -r option default. -s turns it off.
6.0
- Support for decoding DXT5 BLPs.
- Improved the way mip level are created for images with alpha.
- Fixed bug which could cause palettized BLPs with alpha to not have their alpha converted correctly. (Occured when the first transparent pixel uses palette entry zero.)
5.0
- Fixed bug which was causing -g value to be applied twice when using -r and converting a RGBA PNG to a BLP.
- -g will now work when when converting a Palettized PNG that has no alpha.
- Added -h, which forces cHaracter format BLPs. (palettized, no alpha).
4.0
- Added -e and -n options.
- -g option now works when doing a rgb png -> p8 blp.
- -g option will automatically create an alpha channel for RGB source PNGs.
- Removed palettization spam.
- -m option now supports wildcards, ie. *.blp.
3.0
- Removed dependency on DirectX.
- Added -m, -i, and -c options.
2.0
- Fixed bug preventing files from being processed if there was a '.' in their path.
- Now setting device format to current display format, in hopes of fixing an error that people are reporting when the program tries to call CreateDevice().
1.0
- Initial release
This program requires quite a few things in order to compile correctly:
- Windows 2000 and up. I'm unsure about the various libraries but at the very least this file calls win32 functions to handle input wildcards.
- palbmp: A pallete library (C) Charles Bloom. http://www.cbloom.co/m I'm opting to comply with section 0 of the Bloom Public License: I'm distributing this program using the GPL. I've also made some very small changes to it: I commented out the stderr spam.
- crblib: Another library (C) Charles Bloom, which is a dependency of palbmp.
- libpng: The offical PNG reference library. http://www.libpng.org/
- squish: A DXT compression library. http://www.sjbrown.co.uk/?code=squish
- Saving pal/alpha to PNG w/ alpha mask doesn't work right. The moved palette colors don't get updated in the image array properly. Noticible when making Mip test image.
- Dropping more than one file it won't convert correctly.
