Screen DC vs. Printer DC
I have observed (after writing a function to print a stinkin' graphic to a printer) that the printer DC is in quadrant I, however, a screen DC is quadrant I relfected through the X-axis.
The logic of this escapes me. Can anyone explain why MS did the screen this way and why isn't the printer the same way?
Well screen coordinates always have 0,0 in the upper left-hand corner. Screen coordinates follow the path of the electron gun of a CRT monitor, which goes row by row, left to right top to bottom (same way as English text).
Why not the printer then? In theory, the printer starts at the top of the page (0, 0) and works its way down row by row too.
EDIT: Wait, wait. . . I'm all confused. . . the printer and screen have the same coordinates. . . I'm just goofy today.
EDIT EDIT: No, I'm not confused, well, I am, however, the printer appears to start at (max-y, 0) and goes through (0, max-x).
