Note: This function is only available if PHP is compiled with the bundled version of the GD library.
Parameters
- source_image - The source image link
- angle - Rotation angle, in degrees.
- bgd_color - Specifies the color of the uncovered zone after the rotation
- ignore_transparent - If set and non-zero, transparent colors are ignored (otherwise kept).
