    Imagick::colorMatrixImage — Apply color transformation to an image

    Description

    publicImagick::colorMatrixImage(array$color_matrix = Imagick::CHANNEL_DEFAULT): bool

    Apply color transformation to an image. The method permits saturation changes, hue rotation, luminance to alpha, and various other effects. Although variable-sized transformation matrices can be used, typically one uses a 5x5 matrix for an RGBA image and a 6x6 for CMYKA (or RGBA with offsets). The matrix is similar to those used by Adobe Flash except offsets are in column 6 rather than 5 (in support of CMYKA images) and offsets are normalized (divide Flash offset by 255)

    Parameters

    color_matrix

    Return Values

    Returns true on success.
