There are lots of time when you need to make these calculations - due usually to information or interfaces provided by other software (often defined primarily for print) - in my case I need to pass inches to the shell and therefore convert to inches from the rect in Rev,
So the question is exactly what is involved in moving from lets say 640 x 480 image rect to a value in inches that you must supply to a piece of print orientated software? At one time I thought it was just 72 dpi = an inche - but then I never got straight the use of points and pixels and "dots" per inch. I know what dpi are in print world - I know (I think) what pixels are in the "screen" world. That is i think I do :) - Pixels are little glowing spots on your screen - Dots are little non-glowing spots of colour (usually on paper) - the rect and loc etc in Rev refer to pixels of glowing colour - inches and other conventional measure refer to fixed distances in space (relativity not withstanding) - to get from pixels or dots to some real physical measure you need to know the number of pixels or dots per unit of space on the output device concerned (paper or screen) - dpi is this factor and the dpi of monitor screens used to be 72dpi I think all though tis should really be pdi for pixels per inch or gdpi for glowing dots per inch. 96 is another number entirely. Can someone help me here - I think I am in the wrong tree - how do I know the dpi factor to use in a conversion? _______________________________________________ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
