I'm using Photoshop/Illustrator to design the layout of my game's title screen. When I have finished, in addition to exporting each button/image for the programmer to implement, I also want to let the programmer know the exact coordinates of where to put each button.
As far as I have searched I cannot find an easy way to do this. Currently I use the ruler tool to measure and type in the measured number by myself. I am looking for a tool that after you dragged the ruler to measure, the guide is automatically put in the image.
