Combine RGB buffers to give grey-scale

Combine RGB buffers to give grey-scale

This option will combine the contents of three buffers, one containing each of the Red, Green and Blue components of an image, to produce a grey-scale image representing the equivalent intensity of the full colour image defined by the three buffers (this full colour image may be dithered to a single buffer using [C Combine to create full colour image]). The resulting image will be displayed using the monochrome output look up table (0).

Buffer storing red component ?

This entry specifies the source buffer containing the red component of the image.

Buffer storing green component ?

This entry specifies the source buffer containing the green component of the image.

Buffer storing blue component ?

This entry specifies the source buffer containing the blue component of the image.

Buffer for grey-scale image ?

This entry specifies the buffer into which the grey-scale image is placed. The image is produced by adding 0.3*Red + 0.59*Green + 0.11*Blue.
