Dear all ranchers,
I read this in the Java SE 1.4.1 API doc:
======================================================
Rectangle(int x, int y, int width, int height)
Constructs a new Rectangle whose top-left corner is specified as (x, y) and whose width and height are specified by the arguments of the same name.
======================================================
But I found the first two args really represent the "bottom-left" corner of the rectangle. What's the coordinate convention in Java library? Do I mistake something?
Regards,
Pin Ting

You might be confused because in Java, as in most computer graphics environments, (0, 0) is the upper left corner of the screen, not the lower left, and increasing the Y coordinate moves downward -- the oppposite of a "normal" Cartesian coordinate system.
