Does anyone know if there is a website that shows a ruler or a to-scale measurement (which will obviously be limited to the size of my screen)? For example, if I wanted to see 3", I would like a line of that length, showing the relevant subdivisions, or something similar.
I’ve tried googling without success.
Why do you need a website as opposed to a program, of which there are many?
Because it never occurred to me that there would be such a thing; but thank you for the link (and your pre-edited comment. :))
Without having any idea what the application is, it’s hard to know if this will work, but Photoshop has an integrated ruler as well, which leads me to believe that it’s free competitor GIMP probably has one also.
I’m not sure this could work automatically. Your computer only sends out rows of pixels; it doesn’t know how big your display device’s pixels are. For instance, you might be looking at the same image on a 14" laptop screen and on a five foot screen from a projector.
Thisis exactly what I was looking for.
Wow. It’s been a long time since I saw a program who’s requirements simply said “Windows.”
Well it would appear that some of us are going to need to upgrade hard drives, what with that newfangled 600 KB of hard drive space required… 
Of course you have to calibrate it - once. Then you can move the ruler around, rotate it, etc.
Yeah, but once you get one of those 20MB hard drives, your storage requirements will be met forever. Imagine it, dude!
Twenty! Mega! Bytes!
Yeah, but imagine the box of floppies you’ll need to back it up. It’s too big,man.
Good point. Sheesh, these dag-blasted things sure are complicated.
Hey, anybody know how to troubleshoot a Hercules graphics card?
