Perfect Circles ( replies )

Recently I posted the following questions:


------------------- posting dated 28 April 1994 --------------------

On my monitor these pictures appear as perfect circles. 
Both the vertical and horizontal diameters physically measure 9 cm 
on screen.  


How do they look on your monitor ?  

Perfectly circlular ?
Vertically oval ?
Horizontally oval ?

This is your code on the VAX       This is your code on the SGI



My monitor is a 1985 Commodore monochrome with 80 columns x 26 rows.
The effective screen width is 22.5 cm x 17 cm, allowing the 1 cm 
at the left margin before column 1 appears on screen. 


What are the reasons for variations in aspect between different 
hardware ?

In response I got the following answers:

1> The circles appear as perfect circles.

2> I get Vertical ovals.

3> The circles appear as horizontal ovals on my monitor.
   I'm using a dumb terminal on a unix system.

Bye,

I think that the reason you see the circles as 'squished' is that 35l-80c is
NOT standard......I think the standard layout is 24/25 lines - 80 colomns.
Then again, I could be wrong!.... :)
