PixelCalc

PixelCalc is a very convenient tool for anyone working with digital images, whether from a Camera, scanner or other input device. It is especially useful for graphic designers who work with both Web and Print media. Either of these two areas of media frequently require conversions from Pixels to Inches and Inches to Pixels along with a desired Resolution (i.e. hi-res, medium-res or low-res).
Now includes a Proportional Calculator and three useful Reference Charts.
