Convert to Grayscale
The Convert to Grayscale command converts an
RGB image to an intensity-equivalent grayscale image having RGB
pixels. In the resulting image, each pixel value has R = G = B. The
conversion is done by applying a weight to each of the R, G, and B
channels, These weights can be the standard grayscale conversion
values or can be set as desired (see below). To convert an RGB
image to a 16-bit or 8-bit grayscale image having 1 channel per
pixel, use the
Convert to 8 bit Intensity or
Convert to 16 bit Intensity commands.

The Convert to Grayscale command opens
from the Image Window > Process
> RGB Images menu and button on the Main Toolbar. The "immediate" form, shown first,
opens when an image or image set is displayed in the top-most
window. The general form can be used to select source images from
folders, windows, or by matching templates.

This command allows you to specify the color
balancing factors for weighting each channel in the RGB image.
There is a standard formula for converting color data to equivalent
intensity as perceived by the human eye. You can recover these
standard settings by clicking the [Standard] button.
