I don't understand why you're having such problems with this. An 8X10 image @ 300 dpi is a 2400 X 3000 pixel image. Resize this image to whatever pixel dimensions you want for display purposes. You're confusing yourself with the 72dpi. That's irrelevant. Don't worry about it.
For a 5X7 @ 300 dpi, you'd have to resample your image to 1500 * 2100 pixels. For a 4X6 @ 300 dpi, you have 1200 * 1800 pixels. ----- Original Message ----- From: Rick Faircloth <[EMAIL PROTECTED]> Date: Thursday, September 11, 2003 11:12 am Subject: RE: Image manipulation > It was the resampling that was complicating the discussion...my bad... > > But that brings me back to my original question about the CF image > manipulation tags.
