Pixels to MM2
Hi there
I use a vision application to identify different objects, and their size is measured in Pixels. I have a number of circular finds that I need to convert from pixels to MM squared. They are 9, 40, 55, 71, 107 and 191 pixels (area). Now, it also works out that in the future, I am going to have to find objects with area's from 3 pixels to 400 pixels. Is there a way that I can convert these figures from Pixels into MM squared? I have measured, and a straight line distance of about 45mm is 200 pixels. I know its a long shot, but consider it a challenge!! Thanks in advance Jon |

I'm sure if you google on this you'll stumble into a conversion chart or two...<g -- Garry Free usenet access at http://www.eternal-september.org Classic VB Users Regroup! comp.lang.basic.visual.misc microsoft.public.vb.general.discussion |
