Description Charles Werner 2006-05-05 06:59:48 UTC 
1. When adding arrows to arcs, the direction of the arrowhead is incorrect.

2. When dragging the arc with the arrowhead, it leaves a trail of black pixels on   the screen.

3. When attempting to resize the arc, the program hung

Could you attach/link to a screenshot of issue?
Comment 2 Hans Breuer 2006-05-13 22:07:40 UTC 
Sorry cant reproduce anything beside 2) - a known issue mentioned elsewhere.
For 1) I was thinking about being related to bug 331372.

If you (or anyone reading this) can reproduce the issue it may be possible
to get some info from the "console dump" running "dia > dia-bug.log"
Comment 3 Lars Clausen 2006-05-26 19:38:20 UTC 
For 1), do you mean that the angle of the arrow is off compared to the end of the line?
Comment 4 Charles Werner 2006-05-29 06:22:53 UTC 
Exactly, The angle of the arrow is off compared to the end of the line. Originally I thought it was pointing the wrong way.

As for 2, The trail of black pixels when dragging an arc with the arrow is still
an issue that may be related.
Comment 5 Steffen Macke 2007-08-06 20:05:50 UTC 
I don't know if the arrowhead direction is still a problem, but
I can reproduce the "trail of black pixels" when moving the end of the arc
using today's SVN head on Linux.

For the angle that is off: could you attach some sample screenshots to illustrate the problem?

Comment 7 Hans Breuer 2007-10-06 20:10:27 UTC 
there are issues left with degenerated arcs but otherwise this is handled:

2007-10-06  Hans Breuer  <hans@breuer.org>

	* lib/arrows.c : major restructuring - getting calculate and draw by
	function pointer. A lot of arrows are converted to the new style thus
	arrow_bbox() can give the correct bounding box.
	* objects/standard/arc.c : bug #340705 and bug #477569
	  objects/standard/bezier.c : bug #300055 
	  objects/standard/line.c objects/standard/polyline.c 
	  objects/standard/zigzagline.c : not using *BBExtra to adjust the 
	bounding box for arrows but instead a combination of arrow_bbox()
	and calculate_arrow_point() 
	* lib/bounding_box.c : just a comment for now
	* samples/arrows.dia : more coverage

In version 0.96.1 it is still not resolved.

Yes, I know. Please look at the filed "Target Milestone".
