is the green value for an RGB image and is ignored for all other image types.
is the blue value for an RGB image and is ignored for all other image types.
Details |
SET_PIXEL acts on the currently selected image. It can be used with either a new image or an existing image. The colors for a CMAP and an RGB image must be between 0 and 255. If any value is out of range, an error is returned. For a GRAY image, SET_PIXEL returns either 0 or 1 for red.
Use this function carefully, or you can destroy your image data. SET_PIXEL overwrites the image data in memory and thus destroys the original image.

See the example for CREATE_IMAGE.
