Hi All,

I'm having a bit of trouble determining the size of a bitmap. In the following code snippet, the bitmap I'm loading is 32x32 pixels but when I run the code, the reported size is 640x480 (screen size set up previously. Obviously I'm not quite understanding what is going on. Can anyone explain please?

Thanks for that. I looked in the help file and couldn't find the IMAGE WIDTH/HEIGHT commands.

@WindowsKiller - the IMAGE WIDTH/HEIGHT commands aren't documented but they do work as you suggested. Interestingly, the IDE doesn't highlight them either as though they are not recognised as valid commands. Are these two commands relatively new?

@pcRaider - I tried your code snippet and it works fine except that I couldn't see the image I'd loaded. That set me off experimenting a bit and I think I may be starting to understand. Correct me if I'm wrong but the help file says you can load a bitmap with a number from 0-32. I'm assuming bitmap 0 is the screen you can actually see and so the other 32 bitmaps are like 'virtual' screens which you can swop into view with SET CURREENT BITMAP 0

@Orac,

The command are there but as you found out they don,t turn blue and no help file, but I think there something on them in the file update in the bug forum, in 5.5 to 6.0, take a look.

Yes, that right.
BitMap 0 is a special value, and it is screen itself.
SET CURRENT BITMAP 0
When I let a screen display it, I use this.
It may be complicated to understand.


A BitMap command is an outdated old command.
