print/py-collidoscope 0.5.2_2 DragonFly

collidoscope reports on situations where paths overlap in a shaped piece of text.

This software tries every combination of glyphs within a specified Unicode range and up to a specified length of string and outputs a report of all situations where the glyphs collide. It has a number of collision tests:

• Paths in non-adjacent glyphs are never allowed to collide.
• If the cursive test is turned on, then paths with a cursive attachment anchor are allowed to overlap with paths in an adjacent glyph which also contain a cursive attachment anchor, but are not allowed to overlap with a path without a cursive attachment anchor.
• If the area test is turned on, then paths in adjacent glyphs may collide so long as the area of overlap does not exceed a given percentage of the smallest path's area. i.e. if the area percentage is set to 25%25, then two strokes may connect, because the overlap is likely to be quite small compared to the size of the paths involved. But if a stroke significantly overlaps a nukta, it will be reported as a collision. (Of course, this will not detect strokes which merely graze a nukta.)
