| NetPBM (formerly PBMplus) is a package of myriad programs that convert from one graphics format to another and do simple editing and analysis of images. There are no interactive tools in this package, and nothing that displays graphics of any kind. Over 50 graphics formats are handled, including JPEG, PNG, GIF, TIFF, BMP, XWD, XBM, and G3 fax. Over 40 editing functions include scaling, cropping, quantization and dithering, colorizing and uncolorizing, blurring, and dimming. It also includes a C function library which helps you write programs to process graphics at a lower level than the Netpbm utilities. |
