Pimage
processing
The Pimage function draws a Pimage (see Pdecode) on a PGraphic object.
The img parameter specifies the image to display and by default the a and b parameters define the location of its upper-left corner. The image is displayed at its original size unless the c and d parameters specify a different size. The PimageMode function can be used to change the way these parameters draw the image.
The color of an image may be modified with the Ptint function. This function will maintain transparency for GIF and PNG images.
