note 105479 added to function.imagejpeg

Problem: The URL of the current page is displaying in the browser window as an image file. At the same time your manipulated image saves to a file. Solution: Start with removal of the header() function if you plan to output to a file. The browser is expecting image information; therefore, if you are outputting to a file, you don't need a header() function at all. If you are outputting to the browser check your imagejpeg() for parameter 2. Set it to 'null' if it has a file name. Many of the examples programmers illustrate on the web output to the browser and do not save anything to the file system, therefore, the header() function seems essential to image manipulation for the first-time user of the GD library. This page actually clearly shows the difference between "outputting" to a browser and "saving" to a file, but the code comments don't clearly state what the difference is. Search for the page on the "header()" function on this website for more details. Example: Let's say that you are outputting to a jpeg using imagejpeg(). Note the use of the header() function when outputting to the browser. <?php /* more code to make it work */ // These just illustrate the different outputs. // outputting to the browser // header() needed for browser header('Content-Type: image/jpeg') imagejpeg($im); // saving to a file // you do not need a header() function to save to a file imagejpeg($im, "../images/image001.jpg"); // outputting to the browser including quality parameter. // skipping parameter2 to output to browser header('Content-Type: image/jpeg'); imagejpeg($im, null, 90); // saving to a file including quality parameter. // all parameters used for saving to a file with quality adjustment imagejpeg($im, "../images/image001.jpg, 90); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 76.20.11.210 ---- Manual Page -- http://www.php.net/manual/en/function.imagejpeg.php Edit -- https://master.php.net/note/edit/105479 Del: integrated -- https://master.php.net/note/delete/105479/integrated Del: useless -- https://master.php.net/note/delete/105479/useless Del: bad code -- https://master.php.net/note/delete/105479/bad+code Del: spam -- https://master.php.net/note/delete/105479/spam Del: non-english -- https://master.php.net/note/delete/105479/non-english Del: in docs -- https://master.php.net/note/delete/105479/in+docs Del: other reasons-- https://master.php.net/note/delete/105479 Reject -- https://master.php.net/note/reject/105479 Search -- https://master.php.net/manage/user-notes.php
