"Expert" experts - Scaling issues
Posted on 1997-05-07
I want my Delphi 1 application to scale from VGA to SVGA so everything fills the screen and looks the same, but it is not as simple as I thought. Some components need different scaling approaches for the 4 combinations of 800x , 1Kx, large & small fonts, I only use the system font and even that isn't consistent; it becomes a real 'can of worms'. Alternatives seem to be :-
- Write a version for each display mode. It's a huge application and has lots of line draw etc so there will be heaps of work to do this 'simple' task.
- Use a product like 'AnyView' but I believe it won't work on some display cards, especially on notebooks.
- Have the application change and restore the display mode.
This was easy under DOS but can it be done without restarting Windows and will it allow switching between applications. I'm fairly sure it won't.
- It will run mainly under Windows 95 which still seems not to be able to change resolution without restarting.
For 50 points I would like an 'expert' opinion on this issue, not some simplistic reply that says nothing. The concept of scaling seems to be a major fault with the Windows environment, is there a workable solution?
Something that actually works is worth much more than 50 points of course.
