Reads a .bmp file from the given filename
Reads a bitmap out of an in-memory array of data. For example, that returned from std.file.read.
Reads using a delegate to read instead of assuming a direct file
Writes the img out to filename, in .bmp format. Writes TrueColorImage out as a 24 bmp and IndexedImage out as an 8 bit bmp. Drops transparency information.
Basic .bmp file format implementation for arsd.color.MemoryImage. Compare with arsd.png basic functionality.
