Hi to all, I'm trying to write a (at that time) simple GIS-like application based on Cocoa. For each cartographic layer, I use a CALayer object, which is nice to control things like opacity in real-time.
However, I'm facing a challenge: when the user move the mouse, the drawing must move accordingly, feeling in white spaces that appear when updating the position property. However, to feel in those spaces, the app must be able to draw on it, thus the layer shall be resizable in every four direction, including left and below, while maintaining the existing drawing unchanged. I've tried to move the anchor point around and modify bounds or frame, but to no avail: or I get no extension, or I have a transitory motion corresponding to a bound property change (is there a way to disable the implied CASimpleAnimation?). So, put briefly, is there a way to extend a CALayer in whatever direction while keeping its content unmoving? Thanks!
