hi, all I'm zhang li from China. My main focus is performance(loading, saving, asynchronous loading, etc).
I have one fix need for review. It is about odt saving. Please check the below for details, thanks! https://issues.apache.org/ooo/show_bug.cgi?id=120030 root cause: Do profiling on a sample file, SfxObjectShell::GenerateAndStoreThumbnail is to be found occypy too much time, and it will call SwFlyFrm::Paint several times, but it's unnecessary to paint thumbnail so many times when saving. solution: When thumbnail is generated and stored, in SwFlyFrm::Paint, current visible rectangle will be compared with fly frame rectangle, if the two rectangles don't intersect, SwFlyFrm::Paint will return, need no repaint.
