bw2aconv.exe is a simple alpha-layer mask creation tool.
How To Use
Please place a number of BMP files, designated *_b.bmp,*_w.bmp into a directory, and then set bw2aconv to use that directory. A subdirectory called "out" will be created within that directory, and within it the alpha masks for the bmps will be generated.
About The Conversion
Creating alpha masks for BMP files is known to be a laborious process, and this tool is designed to speed that process up somewhat. Here is an example of how it works, and what it requires. Let us say that we have a graphic file to make an alpha mask for, "alice.bmp".
