For 4 bit BMP images the palctrl file sould contain 16 rows, one for each palette index, defining control bits for each color. Two different 4 bit BMP formats are supported, 4 bit Windows BMP and 4 bit OS/2 BMP.
For 24 bit Windows BMP images the palctrl should contain one row only, on the form: f [colorcode] where colorcode is a color in the image that is to be made transparent. It is optional to use a color for transparency.Some examples of palctrl entries are shown below:
f FF0A21
p 0xff 0xff 0xff fullcolor solid normal
i 0 fullcolor solid normal
color_proc options: fullcolor | halfcolor | nocolor
op_type options: solid | halftransparent | transparent |lptransparent
lum_proc options: normal | dark
