In the manual it says I have to create a 128x48 bmp image with 1-bit per pixel, but when i upload it to the phone, it merely displays a full black image.
I've tried:
- creating the image with gimp, saving it as a 1-bit indexed bmp.
convert input.bmp -colors 2 -type Bilevel -depth 1 output.bmp
the latter produces the following output when calling identify output.bmp
:
output.bmp BMP 128x48 128x48+0+0 1-bit sRGB 2c 914B 0.000u 0:00.000
Which looks completely up to specs to me.
Can someone tell what i'm doing wrong, or give me pointers to debug the problem.
