------- Additional comments from [EMAIL PROTECTED] Mon Sep 3 16:45:43 +0000 2007 ------- The problem is caused by rounding errors: In ViewContactOfSdrObj::ShouldPaintObject() the redraw area (the area that has to be repainted) is compared to the paint rectangle of the line. If both have a non-empty intersection then the line is painted. The redraw area is created by invalidating the paint rectangle of the line, and therefore, both rectangles should be identical. However, the redraw area is converted from logical to pixel coordinates and back again. With a zoom factor lower than 100% this leads to a loss of precision and results in general in redraw areas with slightly modified coordinates. In the case of horizontal and vertical lines with a zero height or width this leads to empty intersections between paint rectangles before and after the temporary transition to the pixel coordinate system. Possible fix is to enlarge the redraw area by the logical equivalent of one pixel. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
