From WMTS TileMatrixSet to World File

I am using OWSLib to retreive a single WMTS tile, and want to add a worldfile to that tile so I can present it in a more "simple tool". When opening both the calculated world file in Qgis the image was not positioned at the some point, which made me write everything down. Below can be used to solve the problem.

My input:

wmts.tilematrixsets['EPSG:28992'].tilematrix['00'].topleftcorner
(-285401.92, 903401.92)

wmts.tilematrixsets['EPSG:28992'].tilematrix['00'].scaledenominator
12288000.0

wmts.tilematrixsets['EPSG:28992'].tilematrix['00'].tileheight
256

wmts.tilematrixsets['EPSG:28992'].tilematrix['00'].tilewidth
256

wmts.tilematrixsets['EPSG:28992'].tilematrix['00'].matrixheight
1

wmts.tilematrixsets['EPSG:28992'].tilematrix['00'].matrixwidth
1

A = scaledenominator * 0.00028
D = 0
B = 0
E = scaledenominator * -0.00028
C = topleftcorner[0] + ((column * tilewidth + 0.5) * A)
F = topleftcorner[1] + ((row * tileheight + 0.5) * E)
