Developer’s Corner: GeoServer Stunning image quality + max compression rate = New PNG8 quantizer is served!
Hi everybody,in this blog we want to introduce the new GeoServer PNG8 quantizer.PNG8 is a shorthand for PNG 8bit, that is, a PNG image that uses a fixed palette of 256 (or less) colors and can thus encode each pixel with just one byte.The interest in the format comes from its smaller size, often between 2 and 3 times smaller than the equivalent 24bit PNG image. Smaller size means:proportional size cut in tile cache storage, which normally means cutting away several GB if not TB (depending on the amount of seending and the size of the cached geographic area)shorter transfer...More
