Method imageImpl

core/src/processing/core/PGraphics.java:3992–4042

Expects x1, y1, x2, y2 coordinates where (x2 >= x1) and (y2 >= y1). If tint() has been called, the image will be colored. The default implementation draws an image as a textured quad. The (u, v) coordinates are in image space (they're ints, after all..)

                           float x1, float y1, float x2, float y2,
                           int u1, int v1, int u2, int v2)
