Title: Scaling
Post by: johnno56 on April 09, 2022, 10:23:33 pm
I happened to be resurrecting some 'old' QB programs, mainly dealing with particles, and noticed an annoying recurrence. Most of them use a screen size of around 320x200+...  On my screen, 1920x1080, it seems to be no bigger than a business card in comparison...

My question is; Does QB64 have an inbuilt function to scale the size of the image so that the 320x240 display can 'stretched' to fit a larger screen? It is not an issue or a big deal. I am just curious to know.

Quick demo: 
Code: QB64: [Select]
  3. Print "Hello SCALING World!"
  5.     _Limit 30
  8.  

Compile.  Run.  Grab corner of screen with mouse and drag to desired size so you can see what's on the screen.
