Hi Peter,
Manual adjustment of contentScaleFactor
doesn't look correct. There is MacawView.zoom
property which you can use for zooming. If you want some custom scaling then you probably need to change place
of the root element instead of image scaling (which will be pixelated).
If you'll be able to built a simple sample of what you're trying to achieve then I can help you fixing your code.
Hello @ystrot ,
when I use the MacawView.zoom property, the image still gets pixelated when I pinch. Do you know how can I solve the issue?
Thanks
Could you create a sample project demonstrating your issue?
I only enabled the zoom. Maybe it's a problem with the SVG file? Thanks macawMap.zip
We put together a SwiftUI proof-of-concept using Macaw 0.9.6 in XCode11 using a UIScrollView with a UIViewRepresentable wrapper and a MacawView as the only subview in the scrollview. We're now using XCode12 Beta which will not build with Macaw 0.9.6.
I integrated our PoC work into the project and noticed that there was a significant degradation in the quality of the rendered image. Previously we had adjusted that (for different zoom levels) by altering MacawView.contentScaleFactor. With Macaw 0.9.7 this value no longer has any effect on the rendering process leaving the image heavily pixelated even at low zoom levels.
I put together a test involving porting our project back to XCode 11, running the app on an emulator with 0.9.6 and then updating to 0.9.7 without any code changes (other than to the podfile) and running on a second emulator. The difference in quality is significant and can be seen in the attached image.
