Raster

Usage

• Raster[{{, , ... }, ... }] is a two-dimensional graphics primitive which represents a rectangular array of gray cells.

Notes

• Raster[array, ColorFunction -> f] specifies that each cell should be colored using the graphics directives obtained by applying the function f to the value specified for that cell.

• Raster[array, ColorFunction -> Hue] generates an array in which cell values are specified by hues.

• With the option ColorFunctionScaling -> False the original cell values

, rather than scaled cell values, are fed to the color function.

• With the default setting ColorFunctionScaling -> True cell values in Raster[array] outside the range 0 to 1 are clipped.

• If array has dimensions {m, n}, then Raster[array] is assumed to occupy the rectangle Rectangle[{0, 0}, {m, n}].

• Raster[array, {{

}, {

}}] specifies that the raster should be taken instead to fill the rectangle Rectangle[{

}, {

}].

• Scaled and Offset can be used to specify the coordinates for the rectangle.

• Raster[array, rect, {

}] specifies that cell values should be scaled so that

corresponds to 0 and

corresponds to 1. Cell values outside this range are clipped to be 0 or 1.

• array can be a SparseArray object.
