note 75618 added to function.imagejpeg

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. ---- Server IP: 195.184.96.15 Probable Submitter: 80.161.59.178 ---- Manual Page -- http://www.php.net/manual/en/function.imagejpeg.php Edit -- https://master.php.net/note/edit/75618 Del: integrated -- https://master.php.net/note/delete/75618/integrated Del: useless -- https://master.php.net/note/delete/75618/useless Del: bad code -- https://master.php.net/note/delete/75618/bad+code Del: spam -- https://master.php.net/note/delete/75618/spam Del: non-english -- https://master.php.net/note/delete/75618/non-english Del: in docs -- https://master.php.net/note/delete/75618/in+docs Del: other reasons-- https://master.php.net/note/delete/75618 Reject -- https://master.php.net/note/reject/75618 Search -- https://master.php.net/manage/user-notes.php
