In the FAQ, I found the answer to this question--the image does not have dpi, only the device on which the image is displayed has this property. Still, the following comment was asked but never responded to: Re: In other words, resolution (DPI) is a property of input... Christian Beer, Nov 12, 2001 But you have the opportunity to store that information in some file-formats like JPG, TIFF, etc. How can one get that information? Is it possible to ascertain that information? If Jpegs can be saved with a specified DPI, is it possible to set the DPI with, say, the setPixel() command in the ImageConsumer Interface? Please help. Thanks! Tim    More>>
