How to add more space to an image?

[GrandMasterK]

I've been drawing out a map on a texture image and I've run out of room. I need to add more space on all sides. I'm thinking the only way to do this is to duplicate the texture image and add it to all sides, effectively turning 1 square into 9 squares so I can continue on in any direction. I'm not sure if that's the best way to do it but either way I don't know how to do it?

Use the 'Crop' tool.

When selected you'll get the usual control handles...similar to the transform handles.....drag them OUTWARD to increase the canvas size.

You can also use all the regular 'constrain' keys to drag out uniformly from the center or an edge or whatever.

Regards.

Hello and welcome to PSG.

Are you needing to expand the canvas or the texture itself?
Do you have a screenshot of your texture map?
