Export graphics without borders

Share icon

For publication quality images I prefer to have an image with a simple scale-bar, no axis, no ticks, and no borders.
I can get rid of axis and ticks - but how can I export graphics without borders?
I end up having to do some trimming in Photoshop every time - a step I would prefer to avoid.
I would like to export an image that only includes the image data - no border of any type.
Any help is appreciated.
Here's an example for a regular graph using Igor on the Macintosh:
Make/O/N=(100, 100) theWave = p + q
NewImage theWave
ModifyGraph nticks=0,noLabel=2,axThick=0
ModifyGraph margin=-1
SavePICT/E=-5/B=72  // Saves as a .png file with no border
SavePICT/E=-2  // Saves as Quartz .pdf with no border

The key is to set the graph margins correctly. A value of -1 means no margin (a value of 0 means automatic margins, which is the default).
