The tools/cstester is doing something similar. Please note that there I don't use the QWidgets to render the things into QPixmap but render it directly to QPixmaps. However the usage of QPixmaps sometimes puts a hight load on the xserver as all the pixmaps are transfered to the graphics memory. I plan to change that to generate the images using QImage instead which should solve this problem. Please not that for spreadsheers I only paint the the first page into a pixmap. > Once the project is finished, I'd like to merge it back to calligra but > that depends on you, not sure what is the policy on using private api. I see no problem it it is e.g. added to the tools directory in case you will continue to maintain it.
