SWF::FilterMatrix(3) SWF FilterMatrix class

SYNOPSIS


use SWF::FilterMatrix;
$valueref = [ 0.5, 0.4, 0.3, 0, 0,
0.5, 0.4, 0.3, 0, 0,
0.5, 0.4, 0.3, 0, 0,
0, 0, 0, 1, 0 ];
$filtermatrix = new SWF::FilterMatrix( 5, 4, $valueref );
$filter = SWF::Filter::newColorMatrixFilter( $filtermatrix );

DESCRIPTION

SWF::FilterMatrix is a helper class useful for construction of some SWF::Filter objects: ColorMatrix filter and Convolution filter.

METHODS

new SWF::FilterMatrix($cols, $rows, $valueref)
The only method is a constructor for creation of a FilterMatrix object. The object is controlled by the matrix data dimensions (cols * rows) and the data values: a reference to an array of float values. Note: constructing ColorMatrixFilter needs a 5*4 matrix.
