sizing of quartz and x11 windows
quartz(w=3,h=3) gives me a 2 6/32" square window (not including the banner, but including the resizing square). the measured discrepency between x11 and quartz seems to scale linearly with the size of the windows (an x11 window being 1/64, 6/64 and 12/64" bigger in the 1, 3 and 6" cases), but for both x11 and quartz the resizing square is within the measured square region, so i am not sure the resizing square is the source of the discrepency. i am more wondering why 3" in the function call turns into 2 6/32" displayed. is this a standard error for everyone, or is it just my monitor/card-combo that creates it? and if it's standard, why have a function that purports to deliver a measurement?

The general answer is that your pixels are not squares but they are vertical rectangles, so what you expect is not what you see. As for the small difference in quartz vs x11 I think is because of the resizing square at the bottom-right of the quartz window. So you should measure up to that square and you should get the same height. You should notice this effect by creating 3x3 window and look that indeed it appears as a rectangle. hope this helps stefano On Dec 5, 2005, at 5:28 AM, Parlamis Franklin wrote:
whenever i open an x11 or quartz window, the dimensions of the window are roughly 74% and 72%, respectively, of what i call for. for example: quartz(width=3, height=4) leads to a window that is roughly 2.15 inches by 2.9 inches, and x11(width=3, height=4) leads to a window that is roughly 2.21 inches by 3 inches i am using dual apple cinema 23" displays set at the 1920x1200 resolution. can anyone point me in the direction of understanding why this is happening?
