BMP is an image file format unrelated to hardware devices and is widely used. It uses a bit ing storage format. In addition to image depth options, it does not use any compression. Therefore, bblp files occupy a large amount of space. The image

There is no bmp image generation function in the GD library, so I wrote one myself. there is still a compression algorithm not written, but it is enough. For more information, see. Intimagebmp (resourceimage [, stringfilename [, int $ bit [,
