map exporting

is it possible to to get blender to export a picture of the UV map with like a choosable resolution, normally i would just take a screenshot if i was making a texture, but i need a very high rez texture, along the lines of 4094x4094.

under the UV image editor, there is a function that allows you to do exactly that.

Click on the UV text button, then click on the script named “save UV face layout”
