That´s Xaxctly what i did ! Because I wanted them as Backgrounds....DUH ?
in windowblinds, stretching only works sometimes... my idea is that you have drawn an image you would love to see in the background of your windowblind, depending onthe image, you can do one of 3 things,
1. use the painting margins so the image dosent stretch
2. tile the image (this only works for certain patterns, not really images)
3. use the image as a 'glyph' and you dont have to worry about painting margins.
good luck and hope this helps.
actually, another thought just came to me, you could also turn the image into a texture and use it in the windowblind....depends on the look you wish to achieve.....
