Re: [Pharo-dev] Athens and StrikeFont ( again )
I am not quite convinced we should solve it, actually. We survived for a long time without TT fonts. Now that we finally have them, I think we can manage to survive without Bitmap fonts, too :) Cheers, Doru On Tue, Jul 1, 2014 at 10:05 PM, Nicolai Hess nicolaih...@web.de wrote: 2014-07-01 3:16 GMT+02:00 Igor Stasenko siguc...@gmail.com: On 30 June 2014 21:36, Nicolai Hess nicolaih...@web.de wrote: The real question was: Why can't we draw a text with StrikeFont and with Athens.

I choose the first one, horrible slow or not scaleable is better than a drawing error :) If someday all rendering is done through Athens, how do we solve this problem with the StrikeFont? You would have to implement a special rendering path for StrikeFonts utilizing essentially the same method used for rendering bitmaps. In theory, if cairo bitmap perf is about the same as traditional bitmap perf, that'd be about as slow as FT-rendering is in non-cairo images, if there's no scaling involved. Scaled, it would probably look horrible, take a screenshot of this mail, zoom to 400% in Paint or something, that's what to expect. (Though, one *could* do some tricks translating point size /scale factor to another font with point size closer to the final result (if one exists) and get slightly less horrible results) another solution in: 13458 https://pharo.fogbugz.com/default.asp?13458 Rendering text with Athens and StrikeFonts Here I use Athens/Cairos simple text api. Maybe not a good solution, but it is better than the drawing error, I think. Cheers, Henry
