Basicaly people inside the medical school will be able to choose images to use. Many times these images will be used to create print media. A 96dpi image which is fine for the web pixelates when you expand it to fit a given size. Most of these print publications will be generated on a high quality printer which also uses DPI. Only the original negative and direct prints from that have no DPI just film grain which usually isn't a prob unless you are using really low quality film.
The people browsing the catalog online will need to know if the image they are downloading is of web or print quality. As for use of TIFF files, they are still used with some print publishers. I know more have gone over to JPEGs because of the lower file size, but unfortuately I am replaceing an application that is very old and limited, but I therefor have to provide atleast all the functionality of the old application which included TIFF images for download as well as JPEG. I want to extract the DPI from the image because there is a lot of additional information about the image that will be inserted into a database. Thus to save on dataentry I want to be able to get the system to pre-populate the dataentry screen as much as possible based on the image. IOW the process is like this TIFF emailed with info to dataentry. dataentry uploads the tiff image through a web interface application gathers data and produces smaller versions for on screen display dataentry screen presented with filename, height, width, format, filesize already filled in the person adds the rest of the info from the textual part of the email that has things like dates and photographers image becomes available to end users online Claude Schneegans wrote: > >>Thanks, I did have an older version as it turns out.
