On the Mac, at least, you can simply
- paste the graphic you want from another application
- select the graphics cell
- select the "Convert To InputForm" option from the Graph menu
- assign the Raster[] data in the generated cell to a variable (and/or
save the data to disk
The Raster[] object contains the pixel data you want and has just the
resolution of the pasted image.
