Hi!
It took me some time. I have included your PNG exporter in Roassal.
Cheers, Alexandre

Thanks, however, in my exporter is exactly same problem as in yours, just where your stops creating files, my creates just white background. Interesting thing is that sometimes when it is unable to export, I save and quit Pharo, reopen and it exports fine. I would say something about memory related something, but when I opened 500 windows, it did not stop working because of that. Plus my exporting via morph seems to have another limitation, which is 10000 px on width and height, anything beyond it gets cropped. Anyway, here it is, just updated with scaling down when too large, few fixes (like exporting canvas which is not open anywhere): http://www.mediafire.com/view/7bl4eg9qn3csici/DCTRCanvasExporter.st

Jan, I went through your exporter, and it seems to do an interesting job. I will be happy to include it in Roassal for others to have a look at it.

Well, it seems mine is unable to export large pictures too, just for different reason: memory. Exported BMP for 7500*7500 px image has over 160 MB and Pharo's Windows VM memory limit is only 500 MB

no no no :-(
It does not work for large pictures. Consider the following:
| b | b := RTMondrianViewBuilder new. b shape rectangle withBorder; width: [ :cls | cls numberOfVariables * 5]; height: #numberOfMethods; linearFillColor: #numberOfLinesOfCode within: RTObject withAllSubclasses. b nodes: (Object withAllSubclasses copyFrom: 1 to: 3000). b edgesFrom: #superclass. b treeLayout. b build. ^ b view
Nothing gets on the disk when you save :-(
Jan B. sent me a morphic based exporter.
