hi, I wanted to let people know about the status of my native java2d work. this is visual work and a picture tells at least 1024 words:
http://people.redhat.com/graydon/native-java2d-aug28-2003.png that is not using any sun code, it's all free software. now some qualifications: - most of the rendering there is being done in GDK and cairo, a C library (http://www.cairographics.org), and not in java. subsequently the structure of the work so far is not as open to tinkering on the java-side of the JNI as the java2d APIs might imply. - the text API of cairo is not complete, so there is no text rendering support yet. the dark gray box in that screenshot is the bounding box for some glyph-converted text (via pango), but I cannot render it. when rendering is available it will be through xft (or other low level backends, such as win32 GDI, as needed) - several of the java2d drawing functions are a bit ambiguous in specification, so the way they work might not be what you expect. feel free to correct. - several drawing functions are incomplete, either in my code or in cairo or both. many overloads in the Graphics2D object are missing, and a few cairo APIs are unfinished or missing. both are free software though, and can be fleshed out. - the draw cycle supports conventional AWT offscreen Image-based double buffering, but sometimes this appears to play less than perfectly with the GDK event queue, and gets slightly jerky in its response to update requests. I don't know exactly how this is happening yet. in total there's about 140k of code in 9 new files, plus a handful of little patches around and about. I can post it to the list, or break it up into lots of separate little patches, or post it to a URL for reading.. whatever is preferred. comments? -graydon _______________________________________________ Classpath mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/classpath
