I have a BMP file with fake alpha (similar to rgb32fakealpha.bmp from the bmp suite). That is, it has 32 bits per pixel, but doesn't have bitfields set, but uses the extra bits in each pixel as alpha anyways. And I'm using the twelvemonkeys library with the imageio-bmp plugin to read the BMP.
If I just do ImageIO.read(inputFile)
, then it doesn't preserve the transparency. Is there some way I can configure imageio, to use the alpha channel for this image?
