ID: 21712 Updated by: iliaa@php.net Reported By: gkopp@ideastar.com -Status: Open +Status: Feedback Bug Type: GD related Operating System: RedHat 6.1 PHP Version: 4.3.0 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Using the latest snapshot with identical font, source image and test script I've created an image that is not jagged. For reference I am including a URL to the image created using 4.3.1-dev + bundled GD library. http://bb.prohost.org/img.jpg Previous Comments: ------------------------------------------------------------------------ [2003-01-17 14:33:59] gkopp@ideastar.com Not sure about which libttf version. I know I have freetype-2.0.9 installed on the machine with the link below. Not sure if that helps. http://tpol.ideastar.com/test.php The code that produces bad results: <?php $text = "Jagged Text"; Header("Content-type: image/png"); $source_file = "bluebox.jpg"; $target_id = ImageCreateFromJPEG ($source_file); $fontsize = 36; $xpos = 20; $ypos = 40; $font_color = ImageColorAllocate ($target_id, 255, 255, 255); $font = "/usr/local/www/archer/FRAMDCN.TTF"; ImageTTFText ($target_id, $fontsize, 0, $xpos, $ypos, $font_color, $font, $text); ImageJpeg($target_id); ImageDestroy($target_id); ?> The code that produces good results (trial and error figured this one out): <? $text = "Clear Text"; header("Content-type: image/png"); $source_file = "bluebox.jpg"; $source_size = getimagesize($source_file); $source_w = $source_size[0]; $source_h = $source_size[1]; $source_id = ImageCreateFromJPEG($source_file); $target_id = ImageCreate ($source_w, $source_h); ImageCopyResampled($target_id, $source_id, 0, 0, 0, 0, $source_w, $source_h, $source_w, $source_h); $fontsize = 36; $xpos = 20; $ypos = 40; $font_color = ImageColorAllocate ($target_id, 255, 255, 255); $font = "/usr/local/www/archer/FRAMDCN.TTF"; ImageTTFText ($target_id, $fontsize, 0, $xpos, $ypos, $font_color, $font, $text); ImagePNG ($target_id); ImageDestroy ($target_id); ?> ------------------------------------------------------------------------ [2003-01-17 14:09:01] iliaa@php.net I've tried to duplicate the problem you've described using PHP 4.3.0 using bundled GD and PHP 4.2.3 using standard GD. Both produce absolutely identical images with the TTF (arial) font that I've used. What version of freetype library are you using and if possible can you put the 'good' & 'bad' image online for comparison reasons. ------------------------------------------------------------------------ [2003-01-17 12:59:10] gkopp@ideastar.com They are equal. Basically, this code takes a template image, and places some dynamic text on top of it. It's used to make custom header graphics for a site, without the need to create new images in Photoshop, etc. ------------------------------------------------------------------------ [2003-01-17 12:39:27] iliaa@php.net Are the dimentions of the 'source' image greater, less then or equal to the size of the 'destination' image? ------------------------------------------------------------------------ [2003-01-17 09:18:20] gkopp@ideastar.com I assume the bundled library. Although the unbundled library did exist on this machine before I compiled the new PHP. And it was version 2.0.1. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
