Re: [Pharo-project] Pharo on retina display

by Tudor Girba

Hi Igor, The only reason we were thinking of the bitmap font support was that there was no ready-made vm to get people to use the new canvas. But, if you are getting the vms ready ... this is fantastic. I would say that as soon as they are ready Moose will likely move to Athens.

Sorry, there was no comments on it, because i sent screens to Stef without any explanation, and he decided to forward them to Pharo list. So, some details: there are two screenshots, one rendered by Athens (cairo.png), another is rendered by balloon (what we have right now). As you may noticed, the font quality is lower in cairo.png. this is because i cannot force cairo to use subpixel AA for some reason, so it renders using grayscale AA. It also misses text in text panel (simply because text rendering is not integrated yet with morphic), as for the rest, you see that screenshots is quite similar. Obviously, not all morphs has code for rendering on athens canvas, but i gradually adding drawing methods for more and more. > --Hannes > -- Best regards, Igor Stasenko.

Trust me, even with the nicest formatting, it's not something that you want to read, or to write... Here the formatting is bad because this code is generated by the SpecLayout object.

ahem.. do not confuse: the given screenshot is an image rendered 100% by athens. it is not a screenshot, just for showing that there is some classes in Athens for "font support" :) -- Best regards, Igor Stasenko.

It looks nice! Everything on the screen is rendered by Athens?

I currently working on Morphic rendering (see screenshot) and getting VMs for all 3 platforms Athens-ready. As i said previously, don't expect Athens to support raster fonts. It doesn't makes any sense. With athens, you can always render number of glyphs into bitmaps and draw them as bitmaps later, if you want it, but i wouldn't call it 'font support', it is bitmap support. :) For Cairo backend i did integration with freetype (which already in pharo as you know), which means that you can render any scalable fonts. And if you may know, freetype package supports embedded fonts (i.e. font data loaded from memory), which means you don't even need to have a separate font file along the image, you can keep font in image itself. As for amount of memory, needed to hold truetype font in image: we did a small experiment with Camillo few days ago , we took single font (Deja Vu sans mono), and edited it to have only ascii character set (0..127). The resulting font file size is just 30Kb! Now compare it with following: (StrikeFont allInstances collect: [:each | each glyphs bits sizeInMemory ]) sum 1504444 1.5 Mb of bitmap data for only single raster font with couple fixed sizes. For same size, you could have 1500/30 = 50 various vector fonts (if only ascii character range of course). > Cheers, > Doru > -- Best regards, Igor Stasenko.
