Hi,Man~ I want to consult how to cut out the drawn path image information and output it to the new content through the drawing of the path

I've tried some ways, but I don't know what's better to do with my business scenarios. Because there are complex custom paths, such as star and diamond, to process the selected path image

I tried this examples rotated-image.go ,Solved my problem

The main code is

dc.??Preserve()
dc.Clip()
dc.DrawImageAnchored(im, ...)
