BMP Tools

Three utilities to process BMP files - cropping, splitting and joining them. Unlike many other tools like that, they require almost no memory, being useful to process large data files, such as digital maps.
Further, the bmpjoin tool automatically detects digits in image names and determines how to join them - names such as abc01_23.bmp, def45.bmp are accepted.
