9 kinds of vision

This is an extension for Inkscape which simulates 9 different types of vision. Again it's a color effect and therefore it can be found over at Effects->Color->Color Blindness after installation.

Supported modes:

• normal trichromatic color vision
• protanopia red-green blindness (no red cones)
• deutanopia red-green blindness (no green cones)
• tritanopia blue-yellow blindness (no blue cones)
• typical achromatopsia (no cones; rod monochromat)
• protanomaly (anomalous red cones)
• deutanomaly (anomalous green cones)
• tritanomaly (anomalous blue cones)

Motivation

A few weeks ago someone complained about screencasts being (ab)used as replacement for documentation. I think I saw it somewhere over at reddit or dzone. Well, that rant wasn't all that interesting, really. However, it did point out two real issues: they are useless to the deaf and you lose the advantages of text (searchable, quick scanning etc.). I can't agree more with those bits - it's something that bothered me for ages.

The former can be addressed with subtitles. The latter, however, is more complicated than that. Solving that problem would also solve the issue that screencasts don't really reveal much of their content to search engines. If you put countless hours of work into your screencasts it would be pretty sad if your audience is unable to find them.

Interestingly subtitles are also the solution to this problem. Once they are written (or copy/pasted from the script) you have a complete transcript together with the timing information. With those two pieces (text and time) you can create a transcript where each line can be clicked to seek over to that position.
