michaelham Posted August 10, 2009 Share Posted August 10, 2009 I know this is a newb question but I have been trying to figure it out for days and can't figure out whats wrong. I am using this function to resize images . All is get is scrambled crap. I realize it's the raw code for the image but I can't get it to display. I have tried header('Content-Type: image/jpeg'); at the top of my script but it doesn't help. If i just output the image without resizing using standard html it shows up so I know the location is correct. Any ideas? $photo = imagecreatefromjpeg($photoLoc); $resizedImage = resizeImage($photo,200,150); imagejpeg($resizedImage); function resizeImage($image,$new_width,$new_height=0) { $old_width = imagesx($image); $old_height= imagesy($image); if($new_height==0) // if the height is not specified //....calculate the relative height $new_height= $new_width * $old_height / $old_width ; $new_image= imagecreatetruecolor($new_width, $new_height); imagecopyresampled($new_image, $image, 0, 0, 0, 0, $new_width, $new_height, $old_width, $old_height); return $new_image; } Link to comment https://forums.phpfreaks.com/topic/169676-gd-image-resize-on-the-fly/ Share on other sites More sharing options...
oni-kun Posted August 10, 2009 Share Posted August 10, 2009 I'm not sure your code is right... 'But I tested this code and it works flawlessly, try to create your function again out of this code.. <?php // File and new size $filename = 'test.jpg'; $percent = 0.5; // Content type header('Content-type: image/jpeg'); // Get new sizes list($width, $height) = getimagesize($filename); $newwidth = $width * $percent; $newheight = $height * $percent; // Load $thumb = imagecreatetruecolor($newwidth, $newheight); $source = imagecreatefromjpeg($filename); // Resize imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height); // Output imagejpeg($thumb); ?> Link to comment https://forums.phpfreaks.com/topic/169676-gd-image-resize-on-the-fly/#findComment-895195 Share on other sites More sharing options...
michaelham Posted August 11, 2009 Author Share Posted August 11, 2009 When I use your script I get the same results. My script needs to display in a table, about 10 pictures along with text information that corresponds to each one. If I comment out the header() line in your script I get jumbled junk. If I don't comment it out I get the Internall Server Error 500 because I am trying to modify the header information after things have already been written to the browser. If I move the header() function all the way to the top of my script I get the same jumbled junk but no formatting, table, etc. Just plain jumbled text on a white screen.
