[ft-devel] [ Doubt ] Editing Bitmaps

[k kushal]

I've written code 

1. To generate bitmaps of a font face for desired size and rendering mode.

2. Store 32 bit and 128 bit hashes ( using MurMurHash3 ) for all the characters in a font face.

Now to generate faulty glyphs for testing, I am planning to do these

1. Displacement of image on bitmap

2. Change the grayness of random pixels or a particular stem

3. Add / remove random pixels 

4. Any combination of above

 

Any other kinds of errors in faulty glyphs?
