Font Breaker
This app glitches bitmaps from sfnt inside .dfont, which is a container format for ttf, sfnt and NFNT. This file extension was used in MaxOS X (2000-2013). Today, it can still be rendered by MacOS Tahoe, but not installed.
This app is an MVP prototype to glitch the bitmap strikes from sfnt:
The user uploads a .dfont. The program determines the byte range for sfnt resources.
The user determines glitching parameters: probability of corruption for each byte, and maximum byte offset (which is selected randomly). Each bitmap strike inside the sfnt is glitched after the starting signature. The user can switch between these strikes.
The result can be downloaded or re-glitched.
The UI was inspired by SteamAMP — a skin for Winamp from 2004. There are two windows displaying glyphs: a free-type area where the spacing glitches are rendered with bitmap glitches, and a glyph demo area where all the glyphs are normalized to see the corruption of bitmaps only.
