vertical blindfold request

[colourphilosophy]

hi mark,

I am a type designer from China. In Chinese hanzi, Japanese Kanji & Korean Hangul design, left and right blindfold test is crucial for legibility. I would love to have an added vertical blindfold function. What's more, if the horizontal blindfold could be set manually, it will be perfect for East Asian glyphs design.

It would be useful if you provided sketches of how it should look like.

Since Hanzi/Kanji/Hangul can be written and printed vertically and horizontally, we need to test the legibility of it in both directions. Therefore, the core visual recognition belt which is same like x-height for Hanzi/Kanji/Hangul is in both dimensions. I suggest that the blindfold on left/right & top/bottom sides be colored while the inside bilndfold could be black.
