Raster

  • Raster[ , , ... , ... ] is a two-dimensional graphics primitive which represents a rectangular array of gray cells.
  • Raster[ array , ColorFunction -> f ] specifies that each cell should be rendered using the graphics directives obtained by applying the function f to the cell value .
  • Raster[ array , ColorFunction -> Hue] generates an array in which cell values are specified by hues.
  • If array has dimensions m , n , then Raster[ array ] is assumed to occupy the rectangle Rectangle[ 0, 0 , m , n ].
  • Raster[ array , xmin , ymin , xmax , ymax ] specifies that the raster should be taken instead to fill the rectangle Rectangle[ xmin , ymin , xmax , ymax ].
  • Scaled and Offset can be used to specify the coordinates for the rectangle.
  • Raster[ array , rect , zmin , zmax ] specifies that cell values should be scaled so that zmin corresponds to 0 and zmax corresponds to 1. Cell values outside this range are clipped.
  • See the Mathematica book: Section 2.9.2Section 2.9.2.
  • See also: RasterArray, DensityGraphics, GraphicsArray.

    Further Examples

    This uses an array of values as gray levels in a raster.

    Evaluate the cell to see the graphic.
