[M3devel] screen shots of pixmap problem

[Daniel Alejandro Benavides D.]

Dear Randy:
Could you try to check (with cm3ide)
http://localhost:3800/public/vbtkit/src/lego/Image.i3/Raw#_DECL_ (or just on cm3/m3-ui/vbtkit/src/lego/Image.i3 )
see that line 43 has 
xres, yres: REAL := 75.0; (* in pixels per inch *) 
which is set from the sourcecode (not from the runtime variables).
you can calulate with 1920x1200 screen resolution pixels per inch
first, you apply pythogorean theorem with both catets 
Dp=sqrt(Wp^2+Wh^2)
Then PPI(or Pixels Per inch)=Dp/Di
where Di is the diagonal size in inches (the screen size), as Wikipedia says:
http://en.wikipedia.org/wiki/Pixels_per_inch
 In my case a SyncMaster 753DFX the PPI=96.42351792840054493 (Iguess the monitor you have should have more, rigth?). So you should fixed if needed the PPI rate in the source code or maybe use another variable that has the correct value.

I hope this helps, let me know
Thanks

I managed to get the customer to grab a few screen images that illustrate the pixmap problem we are having.  These screen shots supplied by the customer don't show the full extent of the pixmap problem, but I do think they show the basic issues.  Quality of the bitmaps isn't great, but I think it illustrates the problem.  
 
I think my whole application is fairly sophisticated in its use of Trestle/FormsVBT.  After the delivery, I'll try to provide the community with a portfolio of pictures we can add to the web site to show the capability of Trestle/FormsVBT.
 
The attached ZIP file contains the following files:
1.  splash_1440.bmp = the startup splash screen bitmap viewed at 1440x900 resolution.
 
2.  splash_1920.bmp = same bitmap as #1, but viewed at 1920x1200 resolution.  It is huge compared to #1.  Normally, when you increase resolution on the same screen, the images get smaller, but this time they get larger.
 
3.  aoi_1440.bmp = one of the windows viewed at 1440x900 resolution.
 
4.  aoi_1920.bmp = same window viewed at 1920x1200 resolution.  Notice that the black triangles in front of Polygon and Minutes are huge.  The text seems to be scaling fine, but the bitmaps are scaling much larger to be out of proportion with the text.  Also notice that the choice radio buttons in the Coordinates block are enlarged out of proportion.  If you look at the numeric in the lower right corner you will notice that the numeric text is elevated in the pixmap background rather than centered.  This is because the pixmap has been enlarged.  
 
Hope these screen shots help illustrate the types of problems I am having.  I have another window that has a number of Boolean choice boxes on it.  When you go to 1920x1200 these boolean pixmaps get enlarged so much that the window won't fit vertically on the screen anymore.  The OK, Close, Cancel buttons actually show off the screen, so the user can't even complete the interaction.  This same window at 1440x900 or lower looks fine and fits on the screen with no issue.
 
Any insight folks can supply on how to resolve this issue would be appreciated.
 
Regards,
Randy
