Allows php to process images in a simple way. for example, download the image processing class based on the gb library.

Let php process images easily. For more information, see. The design idea of this class draws on jQuery and uses the concatenation method to operate images, such:

The code is as follows:

$ Image = new UsaImage (array ('filepath' => 'image1.jpg '));
// The Image overwrites an image. parameters 2 and 3 are the x and y positions to be placed.
$ Image-> Overlap ("image99.gif", 10, 10)
// Overwrite the image at a relative position. the last parameter is the scaling ratio. the default value is 1.
-> Overlap2('image00.gif ', array ('right' => 23, 'bottom' => 50), 0.5)
// Scale the image, set the maximum width and height, and scale the image proportionally.
-> Scale3 (1, 300,300)
// Output to the screen. The program header is automatically added, and the type is jpg. IMAGETYPE_JPEG is the constant of the php gb library.
-> Write (IMAGETYPE_JPEG );
