RGB Array -> 8-bit Bitmap

[Kezmondo]

I need to create one large bitmap from a number of smaller bitmaps.

I have taken a number of separate 24-bit bitmaps and pieced the RGB values together as required into one big byte array. Using this array to create one big 24-bit bitmap is not a problem.

But, can I take the array and somehow save the bitmap as an 8-bit or even 4-bit bitmap?

Cheers...

Color conversion is quite tricky, especially when going from a real color format to a palettized format. Better to leave that to the image editiong apps.

Of course, if you really want to do it, try searching google for "color conversion algorithms"

VB can only save bitmaps in 24 bit color. If you wish to save the picture in less, you must first convert it then write your own code to save it. VB doesn't care if you only use 2 colors in your bitmap, it still saves it as a 24 bit bitmap. Although this doesn't matter as a matter of display, saving it as less will save a lot of disk space.
