Imagick::shearImage
(PECL imagick 2, PECL imagick 3)
Imagick::shearImage — Creating a parallelogram
Description
Slides one edge of an image along the X or Y axis, creating a parallelogram. An X direction shear slides an edge along the X axis, while a Y direction shear slides an edge along the Y axis. The amount of the shear is controlled by a shear angle. For X direction shears, x_shear is measured relative to the Y axis, and similarly, for Y direction shears y_shear is measured relative to the X axis. Empty triangles left over from shearing the image are filled with the background color.
Parameters
-
background -
The background color
-
x_shear -
The number of degrees to shear on the x axis
-
y_shear -
The number of degrees to shear on the y axis
Return Values
Returns true on success.
