jdPixelUpscaler upscales images by simply replacing one pixel with several of the same color.
For example, if you set the scaling factor to 2, one pixel becomes 2×2 pixels of the same color. No attention is paid to the surrounding pixels or to transitions. For certain graphics (mainly pixel art or similar in very low resolution), this may give better results than other methods.
Command line arguments and a D-Bus interface are provided for automation.
