Hi, the jenkins server was down due to an internal problem : the JVM does not support too many open files. I hope this problem will not re-appear. I restarted the server this morning and it's now back on line. Regards, Christophe.

If it is not expensive, I think the support for StrikeFonts would still make sense for helping us transition the application from the old canvas to the Athens one without requiring a Cairo-enabled VM. Like that, once we have migrated the code to the new API, we can simply switch to the Cairo/Pango backend. Or do you have another proposal? On another note, how do I make "AthensTextRenderTest test1." work? I mean how should I initialize the default font (or how do I pass it to the AthensTextScanner)? > I am currently working on bundling cairo library with VM > i thought it will take less time, but ... this stuff is terrible to > compose & build unless you are on linux. > I should finish Mac build in a few days (actually i always think that > it will be this day, but then yet another idiosyncrasy prevents me > from finishing it :) This would be so cool.

Hi, Tudor. Yes, i did not implemented support for Strike fonts. Because strike fonts are not scalable, and because no way they can be correctly rendered by Athens: fonts holding a pre-rendered glyph with subpixel accuracy... which working well as long as you don't rotate/scale the bitmap.. and if you do, then output is even worse than gray-scale) So it is useless, and that's why i didn't added support for them in a first place. But if you need it, i can add it. It should be easy to do. Tell me if you need it. I am currently working on bundling cairo library with VM i thought it will take less time, but ... this stuff is terrible to compose & build unless you are on linux. I should finish Mac build in a few days (actually i always think that it will be this day, but then yet another idiosyncrasy prevents me from finishing it :) -- Best regards, Igor Stasenko.

I know what Athens is :). I meant to say that the client code needs to me migrated (EyeSee, Roassal) to the new Canvas. Once this is ready we will be prepared to use Cairo which technically right now requires extra things: install Cairo, use another VM. >> In the process of testing it, I noticed that the text examples do not >> work with StrikeFont.

Ok, but until the text will work with Balloon Athens we cannot do much because both EyeSee and Mondrian need that API.

Again Athens provides an API and Morphs should be migrated to use this API. so as a transition period each morph should get its drawOn: method rewritten as a drawOnAthens: Then you as a Morph user you do not have to change anything. > In the process of testing it, I noticed that the text examples do not > work with StrikeFont.

working with athens balloon

by Tudor Girba

Hi, I would like to get Athens for Balloon loaded by default in a Moose image. The idea would be to make it easy for people to migrate to this interface, to make the code ready for Cairo. In the process of testing it, I noticed that the text examples do not work with StrikeFont. Please note that we are using Pharo 1.4. I tried it by doing the followings: Gofer new squeaksource: 'Athens'; package: 'ConfigurationOfAthens'; load. ((Smalltalk at: #ConfigurationOfAthens) project version: #development) load: 'Athens-Morphic'. And then: AthensTextRenderTest test1. The problem seems to be caused by a missing method: StrikeFont>>getPreciseAscent @Igor: Is this a missing method, or is it something else? Would it be difficult to fix this?

https://ci.lille.inria.fr/pharo/ gives a 502 error. Also is Pharo 1.4-14438 the latest Pharo 1.4? Thanks
