Circular Cutting
Blog
4th December 2020
Today I need to figure out how to slice an image into a circle, and slap it neatly inside the testcard.
-=-=- This shouldn't be "too" hard. There are some lovely functions within Javascript for doing overlays and masks and the like. Unfortunately, last time I tested it, it didn't quite work out when drawing to a canvas. Of course, that was a few years ago, when I'd just started work on Shoebox, and in all that time, I'm fairly sure the basic Javascript capabilities would have improved significantly.. .. but there's a nagging feeling that I'm going to end up having to do it all myself. Instead, then, I'll probably copy the requested image to a resized area, and then run it through a per-pixel function that can strip out pixels beyond a certain radius. That oughta work, right!? Hmm. Not sure how fast it'll be, though. We'll see. Views 126, Upvotes 27
