But the text rendering would be missing, in the OpenGLCanvas part of ROME, and would have to be taken from another library? When i wanted to add text rendering over OpenGL for Lumiere, i saw a couple of external libraries for freetype2 rendering. Just by curiosity, did you have something in mind regarding this?

Re: [Pharo-project] [Moose-dev] rome

Stef, Thanks, that helps. Where does post script fit into it? I am getting a few steps ahead of myself here, but some day it would be important to be able to print on Linux. Sooner than that, it would be nice to do something similar to passing a Windows HDC into a function in a DLL to speed up loops over lots of numbers. If nothing else, the primitives should serve as examples for anything I find missing. One small frustration/irony has been that I now end up using code to turn what should be double arrays into ordinary collections of objects then into text to shove into gnuplot. There are some hints that I might be able to do better, but for now, the graphics from gnuplot are worth looking the other way :) Bill -----Original Message----- From: pharo-project-bounces(a)lists.gforge.inria.fr [mailto:pharo-project-bounces@lists.gforge.inria.fr] On Behalf Of StÃ©phane Ducasse Sent: Tuesday, May 18, 2010 4:22 PM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] [Moose-dev] rome rome is a new api for rendering image and text. the idea is to offer a common api and several backends one would balloon another would be cairo/pango a third one could be morphic30 primitives the idea is to get rome working with the vm primitives and/or balloon then to get it working with cairo via the ROME plugin then we could start to migrate the system to use this api.

[Pharo-project] [BUG] in VM perform primitive

by Igor Stasenko

Hello, i just discovered a serious bug, which prevents from performing a methods which having many args (but not too many for compiler and run normally). The problem is, that VM tries to using the currently active context to push all of the arguments on it, and then just do normal send. But a sender context may be not big enough (small frame) to accomodate all pushed values. In the attachment you can find that running any of PerformTest new doPerformXX leads to primitive failure. I think that we could fix that at the image side, by telling the compiler to always use a big stack frame for following method: Object>>perform: selector withArguments: argArray "Send the selector, aSymbol, to the receiver with arguments in argArray. Fail if the number of arguments expected by the selector does not match the size of argArray. Primitive. Optional. See Object documentation whatIsAPrimitive." <primitive: 84> ^ self perform: selector withArguments: argArray inSuperclass: self class so, when prim 84 fails, it will activate this method and then, there should be enough space to push all method's arguments. -- Best regards, Igor Stasenko AKA sig.

Re: [Pharo-project] [Moose-dev] rome

rome is a new api for rendering image and text. the idea is to offer a common api and several backends one would balloon another would be cairo/pango a third one could be morphic30 primitives the idea is to get rome working with the vm primitives and/or balloon then to get it working with cairo via the ROME plugin then we could start to migrate the system to use this api.
