&reftitle.description;
arrayimageaffinematrixconcat
arraym1
arraym2
Returns the concatenation of two affine transformation matrices,
what is useful if multiple transformations should be applied to the same
image in one go.
&reftitle.parameters;
m1
An affine transformation matrix (an array with keys
0 to 5 and float values).
m2
An affine transformation matrix (an array with keys
0 to 5 and float values).
&reftitle.returnvalues;
An affine transformation matrix (an array with keys
0 to 5 and float values)
