-c .............. colors........ gradient coloration; any valid

PURPOSE: To create a gradient effect at a specific orientation angle.

DESCRIPTION: ANGLEGRADIENT creates a gradient effect at a specific orientation angle.

ARGUMENTS:

widthxheight ... WIDTHxHEIGHT are the dimensions of the gradient image.

-a angle ... ANGLE is the angle for the gradient coloration in degrees. Values must be greater than or equal to 0 and less than or equal to 360. Alternately, values of nw, ne, se, or sw may be specified to have the diagonal angle automatically, computed. For angle=0, the gradient will have the first color at the top and the second color at the bottom. As the gradient-angle is increased, the gradient rotates clockwise. The default=0.

-c colors ... COLORS is any valid hyphenated IM color pair including opaquecolor-opaquecolor, opaquecolor-none or none-opaquecolor for a transition from one opaque color to another or to transparency. If no color pair is specified, then the normal grayscale gradient will be generated. For angle=0, the first color will be at the top and the second color at the bottom of the gradient image.
