C++ library for creating PNG images

The PNGwriter library, which requires libpng, allows you to plot to a 48-bit PNG file, saving it directly to disk. Plotting is as easy as specifying the red, green, and blue values and the x, y coordinates of the pixel. It includes functions for plotting simple geometric shapes circle, rect, line, reading the colour of a pixel, reading in a whole PNG file great for image analysis, plotting and reading in HSV colourspace, and many others that might come in handy.
