Subpixel rendering vm build?

by Stephan Eggermont

Is there a specific reason to not have a pharo vm build with subpixel rendering for non-US use? Stephan

I think I know which I'd end up writing every single time. Same reason I think a lot of the specialized collect:/select:'s out there is pure bloat in a base image, and better left defined to users who prefer it. Cheers, Henry

It is because there are different ways how textemphasis is handled. In a text teditor for example, we use the full Text object. And in a list view it is only the first character/text that defines the emphasis for the whole text line.

Athens/Cairo uses a different way for rending (cairo uses freetype too, but the "normal" pharo freetypeplugin and cairo are using freetype differently ).

Sorry it felt under radar... yes, this does work! however I managed to encounter two more bugs along the way Pharo space: everything is underlined/bold as expected Bloc space: no styling (this is same behavior both before and after loading Free Type) ââ And second thing (that may not be so obvious from the screenshot) is jaggedness of the font in Bloc (that's why I was messing with fonts in the first place). I suspected that Font Hinting (Settings > Appearance > Use Free Type ... > Advanced Features > Hinting) was incorrectly configured, however when I tried to change it it had no effect. So my conclusion that fonts are not yet fully implemented or something else is missing? Or is my system/configuration wrong? (The image is Bloc build #609 from pharo-contribution). I actually have the very same problem in text rendered in Roassal (Athens canvas), so I blame Athens. Is there a solution for this?

Re: [Pharo-dev] Event handling insanity

by Craig Latta

I've had good results debugging GUI subsystems by using the GUI of a remote system for interacting with exceptions. Something goes wrong in system A, but the exception notifier is displayed on system B, etc. It's also helpful to be able to revert methods and classes from afar, as well. For simple use cases, I've used the simulator, too. -C -- Craig Latta netjam.org +31 6 2757 7177 (SMS ok) + 1 415 287 3547 (no SMS)

Re: [Pharo-dev] How to get better fonts?

by Tudor Girba

Do you by any chance have a retina MacBook? If yes, the fuzziness of fonts is due to that.

But considering there is not much developing now for TxText (is it already finished?), we don't even have someone maintaining the bugreport/fixes for the TxText repository.... How will that work? What is the state of TxText, is it ready, what are the next steps and who is maintaining it ? People now working on RubText, changed / fixed / cleanup the SHRBTextStyler. I am afraid we waste yet again resources we don't have. Doesn't Rubric has a different text model ? How will it work with TxText? TxText has its own styler again, again another one. Whats the plan. We have TxTextStyler and 3 different other stylers, which one to use? And there are many classes in TxText (and Athens-Text) for which I don't know 1. Are they supposed to be used or 2. only test classes 3. Are they finished ? 4. Work in progress ? 5. proof of concept ? Or, maybe there is some work going on out of public - do I miss something? nicolai
