Annotation Arrow sizing.

Post by TRVRSE » Tue Jul 22, 2014 9:03 pm

For annotation arros, is there any way to programmatically set the arrows head and line thickness to be different?

I'd like the line thickness to be 1.0f, and the head to be 4.0f.

If not, do you suggest any workarounds to change how the arrow draws?

You can only set the line thickness and make some minor adjustments to the relative size of the target point (ArrowEndAspectRatio property).

You could create an EventMarker object and and set its location to annotation's line end. However, you would have to calculate the angle of the event marker yourself and that requires some extra coding.

Vote up! I would also like to be able to change arrow head size independently from line width.
