I'm trying to rotate a square 360 degrees, and I currently have the following code attached to a slider:
on change val do r.rotate[(pi/4)*val] end
But when it rotates 90 degrees, it looks slightly off compared to 180 and 270:
How would I go about fixing this? ^^;
Hmm. I can tinker with the internals of image.rotate[] to try to make it better behaved. When you need exact 90 degree rotation increments, image.transform[] is more efficient, and will always be precise. Here's a routine you could use as a workaround for now:
on rotated img steps do # modify 'img' in-place based on 45 degree steps: if steps~0 # do nothing elseif steps~2 img.transform["right"] elseif steps~4 img.transform["right"].transform["right"] elseif steps~6 img.transform["left"] else img.rotate[steps*pi/4] end img end
