3. Extending the framework

It’s simple enough to extend the framework. You can extend the font creator with new:

• Color functions
• Effect functions
• Blend functions
• Texture Render function
• Texture save function
• Font info save function

3.2. Good to know

3.2.1. Font Info File

• The colors are usually specified as 3-tuples of integers
• The colors are in the range [0, 255]
• Internally, the colors are converted to floats in the range [0.0, 1.0]

3.2.2. Image

For simplicity’s sake, each function that handle images, expect a numpy array with certain criteria:

• Colors values are in the range [0.0, 1.0]
• image[x, y] will give you the pixel value of (x,y)
• Origin is at the top left corner of the image
• Most images are 4-channel, except for the glyphimage
