Improve draw speed

Hi,


when i have many arrows to one box in the tree layout (50-100 arrows) then the drawing speed is very slow.
The Overview i must disable but when i scroll down or up in the chart he has a delay bevore the new pic comes from 1 second.

What can i do? I use GDI+ and won't fall back to no GDI+.
I use VB6 and the newes fc.dll.
my Arrange options are:
tl.Root.visible = False
tl.Type = tltCentralized
tl.Direction = tldLeftToRight
tl.ArrowStyle = tlaDontChangeStyle
tl.KeepGroupLayout = False
tl.reversedArrows = False
tl.KeepRootPos = False
fc.ArrowsSplittable = False
fc.ArrangeDiagram tl

thx
Henry

Hi,

Check if disabling the antialias mode improves this. If you are using arrow crossings arcs, you could also try if the other ArrowCrossings values improve the speed.

Hi,

ok Antialaising brings much more speed.
I changed 2 the Options of the Overview, and for very big charts i fall back to no gdi+.


greeting
