widthxheight ................... widthxheight of gradient image
-a .............. angle .........orientational angle for gradient;
................................ degrees rotation from a vertical in
................................ clockwise direction; default=0
-c .............. color(s) ..... gradient colororation; any valid
................................ single or hyphenated color including
................................ color-none

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 orientation angle for the gradient effect. It is specified as a -180<=float<=180 degrees. The default is 0, which will produce the standard vertically oriented gradient.

-c color(s) ... COLOR(S) is any valid single or hyphenated IM color including color-color or color-none for a transition from one color to another. If no color is specified, then the normal grayscale will be generated
