CustomScanlineRotation

Returns a pixmap with each row of pixels rotated an amount that depends on its position.

Syntax

• CustomScanlineRotation(pm, i, f, [, d])

  • pm is a pixmap

  • i is a symbol

  • f is a function

  • d is either "h" or "v"

Description

CustomScanlineRotation(pm, i, f, d) returns pm with each row (if d = "h") or column (if d = "v") of pixels rotated f(i) pixels, where i is the position of the row or column.

Examples

CustomScanlineRotation(ExampleData("Sally"), y, round(100⋅sin(y/100)))

CustomScanlineRotation(ExampleData("Sally"), y, round(100⋅cos(sin(y/20)⋅y^2/300^2)))
