lines be curved after a successful call of ExportAsImage

[yhnmj6666]

this is part of image:

and this is part of graph in zoom control

i can't get correct image by calling "ExportAsImage". what's more, after the call, the graph in the control will be twisted like the image as well

Hi, image export is a total pain in WPF. I'll try to reproduce it.
