Pattern Keyword (UNIX only)

Used With Routines:   PLOTS,  POLYFILL, CONTOURFILL

Corresponding System Variable: None.

A rectangular array of pixels (3D for CONTOURFILL) giving the fill pattern.

If this keyword parameter is omitted, POLYFILL fills the area with a solid color. The pattern array may be of any size; if it is smaller than the filled area the pattern array is cyclically repeated.

Example

To fill the current plot window with a grid of dots:

; Define pattern array as 10-by-10.

Pattern = BYTARR(10, 10)

; Set center pixel to bright.

Pattern(5,5) = 255

; Fill rectangle defined by four corners of window with pattern.

POLYFILL, !X.Window([0, 1, 1, 0]), $

   !Y.Window([0, 0, 1, 1]), /Normal, Pattern = Pattern
