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.
