I'm using svg_render to display an svg in a jsui object. I'd likt ot rotate the image, around the centre. Darwin Grosse's tutorial #28 quite a good guide on this to start with.
works fine to rotate and translate can be used to move results around a little, it's tricky to work out the coordinate aorund which the image is rotated and how to translate back exactly so this would be a desired coordinate, such as the centre. At the moment, it's somewhere left and above the top left corner.
Is there any better information on how rotate works with respect to svg images and coordinate systems? Any tips on this appreciated!
