Image.class is a PHP class that can be used to generate images with graphic primitives defined programmatically. It can create an empty image with a given size or load an existing image from a JPEG, PNG, or GIF image. The class can render graphic primitives in the image like drawing a text string with optional border, copying parts of the image to another position, drawing ellipses, rectangles, and lines, and scaling the image to a given size. The generated image can be saved also in JPEG, PNG, or GIF formats.
