gramps/gui/utilscairo.py: new file, currently holds just the warpPath() function, taken from /usr/share/doc/python-cairo/examples/warpedtext.py, with explanatory docs added. gramps/gui/widgets/fanchart.py, class FanChartBaseWidget: draw_text() method: previous logic using cairo toy text API didn't support CTL text. It has been removed, and replaced with a call to a new method, draw_arc_text(). Flagged a subtle Unicode issue in the remaining old code, for radial-oriented text, with a FIXME, I'll probably fix it later as a separate issue. create_map_rect_to_sector() static method: create a transform to use with gui.utilscairo.warpPath(), currently used in draw_arc_text(). Following Benny's code review I have annotated the algorithm and made it hopefully clear, but I guess it could be reworked into a better form if re-expressed with stacked transforms / complex numbers / matrices for easier later maintenance. Meanwhile I have used the same approach as the older code in the file, good enough for a patch under this feature request. The only issue remaining from the code review is whether the create_map_rect_to_sector() function should be moved to gui.utilscairo; see the bug thread. svn: r22548 |
