Ink canvas performance issue #37

Closed philllies closed 9 years ago

philllies commented 9 years ago

Global ink and ink nodes seem to impact the rendering performance considerably when moving, panning and zooming. Consider converting the InkCanvas to a flat bitmap and when in non-edit mode.

Also, performance declines significantly when zoomed in on ink.

Leave this for now, we first need to get #66 done.

Rendering a normal Canvas on a bitmap works perfectly fine with the following code: await renderTargetBitmap.RenderAsync(canvas, 300,300); img.Source = renderTargetBitmap;

not with an InkCanvas, though.
