Graphics and JEWL

Graphics and JEWL

[chris.danx]

I'm having a little trouble with a graphics application i'm writing.  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.


Thanks,
Chris Campbell

Oh bugger, i just thought of something.  I could divide the x resolution by
y resolution or something like that.  That'd work, right?

  Remember most screens are not square.  As I recall, 4x3 is standard,
so 640x480 gives you square pixels.

Pretty much. Assuming your pixels are the same width as their height,
of course.
