; Name...........: _GDIPlus_TextureCreate
; Description ...: Creates a TextureBrush object based on an image and a wrap mode
; Syntax.........: _GDIPlus_TextureCreate($hImage[, $iWrapMode = 0])
; Parameters ....: $hImage - Pointer to an Image object
; $iWrapMode - Wrap mode that specifies how repeated copies of an image are used to tile an area when it is
; +painted with the texture brush:
; |0 - Tiling without flipping
; |1 - Tiles are flipped horizontally as you move from one tile to the next in a row
; |2 - Tiles are flipped vertically as you move from one tile to the next in a column
; |3 - Tiles are flipped horizontally as you move along a row and flipped vertically as you move along a column
; |4 - No tiling takes place
; Return values .: Success - Pointer to a new TextureBrush object
; Failure - 0 and either:
; |@error and @extended are set if DllCall failed
; |$GDIP_STATUS contains a non zero value specifying the error code
; Remarks .......: The size of the brush defaults to the size of the image, so the entire image is used by the brush
; After you are done with the object, call _GDIPlus_BrushDispose to release the object resources

Müsste genau das machen was du gesagt hast. 
Wofür ist das ganze? Vielleicht geht es auch einfacher.
