The accessor external-image-color-table
gets and sets a vector containing RGB color specifications representing the color table as specified in external-image.
external-image must be a plain external-image. See 13.10 Working with images for details.
If the result is nil
, the external image is a 24-bit DIB, with the colors defined in each pixel instead of through a table.
When setting the color-table of an external image, the new color-table must be the same length as the external image's original color table.
