I want to change an image depth of bitmap for testing purposes. Right now I am trying to get a 2 bit palette image, and a 4444 Hicolor image.
I have a true color bitmap. I used the below command line
convert -depth 2 /media/bitmap/rule.bmp lut2bpp.bmp
then when I used identify I got this
Image: lut2bpp.bmp Format: BMP (Microsoft Windows bitmap image) Class: PseudoClass Geometry: 720x480 Type: Palette Endianess: Undefined Colorspace: RGB Channel depth: Red: 8-bits Green: 8-bits Blue: 8-bits
It changed it to a palette which is great, how do I get to change channel depth?
How about changing that true color 24 bit image to hi color 4444 image?
