PatternFilling["name"]uses the specified pattern "name".PatternFilling[obj, size]specifies the size of the object obj.PatternFilling[obj, size, {dx, dy}]moves the object obj by the offset {dx, dy}.
Examples
Graphics[{PatternFilling["Checkerboard"], Rectangle[]}]Graphics[{PatternFilling[Graphics[Circle[]], 20], Polygon[{{0, 0}, {1, 0}, {0.5, 1}}]}]Please visit the official Wolfram Language Reference for more details.
