Pgmhisteq software enhances contrast in portable graymaps.
One of the most impressive features of pgmhisteq is its ability to ensure that after processing, for each x between 0 and 100, x percent of the image will have a brightness of at most x percent. This functionality makes it very easy to achieve precisely the effect you want to see in your images.
Lastly, it's worth noting that pgmhisteq needs the pbmplus libraries to function correctly. However, once you have these libraries installed, you can enjoy all the exciting features and benefits of this powerful image processing software.
