Abstract: Xqvss R4 server (cc & gcc) returns incorrect display size
in millimeters.
The following code (from the xpostit function CreateNewNote)
returns an incorrect display width and height in millimeters
when run against a Xqvss R4 server.
---
hpixel = DisplayHeight(display, DefaultScreen(display));
wpixel = DisplayWidth(display, DefaultScreen(display));
hmm = DisplayHeightMM(display, DefaultScreen(display));
wmm = DisplayWidthMM(display, DefaultScreen(display));
/*hmm = 280;
wmm = 320;*/
hpi = (int) ((25.4 * hpixel) / (float) hmm + 0.5);
wpi = (int) ((25.4 * wpixel) / (float) wmm + 0.5);
printf("hpixel %d wpixel %d hmm %d wmm %d hpi %d wpi %d\n",
hpixel,wpixel,hmm,wmm,hpi,wpi);
-----
The result when a new note is opened is the following:
hpixel 864 wpixel 1024 hmm 10972 wmm 13004 hpi 2 wpi 2
^^^^^^^^^ ^^^^^^^^^
My display does not even come close to 10 by 20 meters?:-) :-(
Any suggestions? Where do I look in the server?
The code works correctly against the R3 server.

The function mfbScreenInit is called from the function qvssScreenInit. This particular code happens to be surrounded by some #ifdefs, which if not properly defined may be causing the problem. I suggest that you look closely at qvss_io.c around line 360 to determine if you are compiling with the necessary configuration parameters. ========================================================================== Marc Evans - WB1GRH - evans@decvax.DEC.COM | Synergytics (603)893-8481 Unix/X-window Software Contractor | 3 Koper Ln, Pelham, NH 03076 ==========================================================================
