note 75618 rejected from function.imagejpeg by tularis

Note Submitter: tina at damborg-graphic dot dk ---- Do anyone know wether it is possible or not to change image resolution (dpi) via the GDlib image functions, or do I have to use IMagick? I know 72 dpi is the standard for on-screen content, but what if I have to have php make images suitable for printing? The user uploads digital camera images, the image is resized by GDlib, the user modifies the image via a flash application, and flash sends information to the script, adding the changes to a copy of the image. Finally the script saves the image for printing, but when printed the image does not fit the 10x15cm media because of the 72 dpi resolution.
