Link antialias problem

Hi,

we are using your components to draw an organization chart.

We are experiencing some issues related to antialias of links that sometimes at certain zoom levels completely disappear. The behaviour is not consistent, since the same links may reappear at a lower or higher zoom level with respect to the one at which they disappear. Moreover, links which have the same thickness appear as they are different.

The link thickness is set to .7 since they are just too big for an A4 page size. But the same issue sometimes happens even with a tickness of 1

We've tried the SnapToDevicePixel setting with no success.

Con you point us to the right direction to fix the issue?


Bye Agus.

Nevermind,

I've tried to set the SnapToDevicePixel to false and the behavior and the appearance of links seems correct now.

Probably the default of SnapToDevicePixel is set to true for links and I had tried with true.

Bye, Agus.

Hi,

If you are seeing this effect after upgrading from older version of the control, it happens because we changed the DiagramItem base from UIElement to FrameworkElement in the v2.4 release. SnapsToDevicePixels default value is false for UIElement and true for FrameworkElement.

I hope that helps,
Stoyan
