说明
netpbm is a toolkit of over 350 separate programs for manipulation of graphic images, including conversion between about 100 graphics formats. The programs use PNM (Portable Any Map) and PAM as intermediate formats for pipeline-based image processing. The tools are designed for command-line use and pipeline composition. A typical workflow converts an input format to PNM, applies transformations, then converts to an output format. Each tool does one thing, and they are most powerful when combined in shell pipelines.
