bmp2array4bit.py creates C (or C++) code that contains two arrays for adding images to four-bit sprites. See Sprite_image_4bit for an example.
|
|
|
|
It is loosely based on Spark Fun's bmp2array script.
|
|
|
|
You'll need python 3.6 (the original use Python 2.7)
|
|
|
|
usage: python bmp2array4bit.py [-v] star.bmp [-o myfile.c]
|
|
|
|
Create the bmp file in Gimp from any image by:
|
|
|
|
. Remove the alpha channel (if it has one)
|
|
Layer -> Transparency -> Remove Alpha Channel
|
|
. Set the mode to indexed.
|
|
Image -> Mode -> Indexed...
|
|
. Select Generate optimum palette with 16 colors (max)
|
|
. Export the file with a .bmp extension. Do NOT select options:
|
|
. Run-Length Encoded
|
|
. Compatibility Options: "Do not write color space information"
|
|
. There are no Advanced Options available with these settings
|

I don't have photoshop so cannot help you with that.
|
|
|
|
The first array produced is the palette for the image.
|
|
The second is the image itself. |
