The BMP bitmap is displayed in a common way, which occupies a large memory and is slow.

We all know that the PHP GD library can easily create a new image from the URL, GD has Imagecreatefromjpeg (), Imagecreatefrompng () .... And so on function can sometimes read from the URL of the cut BMP images and hateful is GD2 imagecreatefrombmp () Although there are imagecreatefromwbmp () but still the difference is still very far! Use the following function to facilitate the solution Copy Code code as follows: function Imagecreatefro
