NAME

6       SWF::FilterMatrix - SWF FilterMatrix  class
7

SYNOPSIS

9               use SWF::FilterMatrix;
10               $valueref     = [ 0.5, 0.4, 0.3, 0, 0,
11                                 0.5, 0.4, 0.3, 0, 0,
12                                 0.5, 0.4, 0.3, 0, 0,
13                                 0, 0, 0, 1, 0 ];
14               $filtermatrix = new SWF::FilterMatrix( 5, 4, $valueref );
15               $filter    = SWF::Filter::newColorMatrixFilter( $filtermatrix );

DESCRIPTION

18       SWF::FilterMatrix is a helper class useful for construction of some
19       SWF::Filter objects: ColorMatrix filter and Convolution filter.
20

METHODS

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