trneg
Description
Negates the raster graphic assigned to the currently selected frame. Negation of an image involves reversing the brightness level of each individual pixel so that the image appears as it would on a photograph negative.
* 
Performing a second trneg action on the same graphic will restore the original image.
Syntax
trmove
Additional Information
You should note that trneg actually changes the raster graphic itself; it is not just a frame attribute. The raster graphic will be affected in every location it is used in your document. If you do not want this to happen, copy the raster graphic using trmk or, if necessary, re-import the raster with a different tag name.
