Hexagon filled with a texture

[Petr5CB8]

I need to draw pictures - see attachment. The hexagon should be filled with a texture read from a disk file. In addition - the edges of the hexagon must not be smoothed. The resulting image is used in a program that automatically makes the magenta color transparent, but only pixels RGB (255,0,255). Is it possible to create such an image in the program?

You can draw out a Hexgon using the Pologon Tool, put your texture in a layer above using File>Place then go to Layer>Create Clipping Mask.
