Raster

Raster[{{a₁₁, a₁₂, ...}, ...}]
is a two-dimensional graphics primitive which represents a rectangular array of gray cells.

Raster[{{{r₁₁, g₁₁, b₁₁}, ...}, ...}]
represents an array of RGB color cells.

Raster[{{{r₁₁, g₁₁, b₁₁,

₁₁}, ...}, ...}]
represents an array of color cells with opacity

_ij.

Raster[{{{a₁₁,

₁₁}, ...}, ...}]
represents an array of gray cells with the specified opacities.

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.

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

Raster[array, {{x_min, y_min}, {x_max, y_max}}] specifies that the raster should be taken instead to fill the rectangle Rectangle[{x_min, y_min}, {x_max, y_max}]. »

Raster[array, rect, {a_min, a_max}] specifies that cell values should be scaled so that a_min corresponds to 0 and a_max corresponds to 1. Cell values outside this range are clipped to be 0 or 1.
