Hi,

There's a folder in the zip file called "NoAlpha" which has versions of all the tileset layouts without alpha blending, just fully opaque or fully transparent pixels. You can use these to make a bitmask by filling in the transparent pixels with your 0 value colour and all the solid pixels with your 1 value colour (or the other way round, depending on how you're doing things).

The shadows that are designed to be drawn with transparency have the RGB value #664d8b (102,77,139), so if you're doing alpha blending through bitmasking you can fill all these pixels with whatever value of greyscale you want depending on how transparent you want the shadows to be (I used 0.37 in the tileset).

Hope this helps.
