A found low resolution image (60×96 pixels) of a rug, enlarged factor 6 with my self-invented diagonal enlarger algorithm, then enlarged 4 times with a regular nearest neighbour enlarger.

A found GIF image (50×50 pixels) of a panda, enlarged factor 100 (5000×5000 pixels) with a self-invented diagonal enlarger algorithm.

I wondered, when enlarging low resolution bitmap images, if it were possible to come up with an alternative to square rectangular pixels. Why not extrapolate the connections between enlarged pixels diagonally? This resulted in new textures, while remaining perhaps more truthful to the original structure and composition.

These images were calculated in 2009 and minted in 2022.
