The application uses JEWL 1.4 and it is to display 'bugs', the insect kind, on the screen. The problem is to do with the aspect ratio of graphics. A textual description of the bugs is found in a file and read into the system and drawn. The problem will be that when the bug is rotated from say north to say west it will be drawn out of shape. I know how to fix this in general, simply ask for the aspect ratio and multiply by it to get the correct display size. The problem is i don't know how to do it for JEWL. Is there a good estimate for most displays? Can i work it out? I plan to have a square grid with each bug occupying 1 square pointing in one of the 4 main compass directions.

I could divide the x resolution by y resolution or something like that. That'd work, right? ^ permalink raw reply [flat|nested] 5+ messages in thread

Remember most screens are not square. As I recall, 4x3 is standard, so 640x480 gives you square pixels. ^ permalink raw reply [flat|nested] 5+ messages in thread

Assuming your pixels are the same width as their height, of course. ----------------------------------------------------------------- John English | mailto:je@brighton.ac.uk Senior Lecturer | http://www.it.bton.ac.uk/staff/je Dept. of Computing | ** NON-PROFIT CD FOR CS STUDENTS ** University of Brighton | -- see http://burks.bton.ac.uk ----------------------------------------------------------------- ^ permalink raw reply [flat|nested] 5+ messages in thread
