- One of the display limitations I felt of Khoros was that the print
- pixel values function showed the display color and the display pixel
- intensities - not the true pixel intensities. A slight modification
- to run_pixels.c in src/xvroutines/editimage was all that is needed.
-
- The diff is shown below.
-
- In editimage, Print Pixel Values now prints the true pixel value but only
- when in grey mode.
