Why is it that when i read a bitmap and display it with display_image() =
it does not come out in the right color ? Like when the color must be =
blue it comes out yellow .
Here is my code :
include image.e
include graphics.e
object mode,bitmap
mode =3D graphics_mode(18) -- I tried all the other modes
bitmap =3D read_bitmap("test.bmp") -- The bitmaps name is test.bmp but =
it can be
-- any other name .
display_image ( { 0,0 } , bitmap [2] )
I have an ATI Rage IIC 8 MB .
thanks

you need to set the palette:
all_palette(bitmap[1]/4)
also, mode 18 only has 16 colors, so unless you have a bitmap with 16 colors,
you'll need to use a different mode
