Filling shape with color is slow.

[topDev15]

I'm using this framework to show SVG file and changing color of Shape. Btw filling color is slow. It takes 1 second for changing color of shape. shape.fill = Color.white

How can I speed up?

Hi, @AndreasB115, did you make time investigation which functions/parts of Framework actually slow?

[topDev15]

@amarunko Yes, It takes about 1 second when I'm trying to change color.

hi @amarunko

I found following in SVGKFastImageView.h:

• Apple's implementation of UIScrollView is badly broken for zooming. To workaround this, you MUST disable the auto-redraw on this class BEFORE zooming a UIScrollView. You can re-enable it after the zoom has finished. You MUST ALSO make a manual call to "fix" the transform of the view each time Apple sends you the "didFinishZooming:atScale" method. There is an example of this in the demo project (currently named "iOS-Demo.xcodeproj") showing exactly how to do this. It only requires 2 lines of code, but Apple's documentation makes it clear that this is the only way to work in harmony with UIScrollView's internal hacks.

Where can I find this project: iOS-Demo.xcodeproj?

Bad case, I will try out the reason. About scroll view - I didn't know, but I think using UIGestures with macaw is a better approach because Macaw uses custom rendering. This example related to libraries which we didn't use.

Actually, for zooming in macaw, you can use special classes - MacawZoom
