Req #72912 [NEW]: GD and rtl languages

From: hirad dot daneshvar at gmail dot com Operating system: PHP version: 5.6.25 Package: GD related Bug Type: Feature/Change Request Bug description:GD and rtl languages Description: ------------ --- From manual page: http://www.php.net/function.imagettftext --- I can add text watermarks to my image, however the text must be a Left To Right language. How can I use RTL languages such as Persian to add a watermark? For example a text like سلام will be added like م ا ل س. I have searched A LOT, and all I found was custom functions to do so. However persian letters unlike Latin letters should be connected. For example in the word 'Hello' there is a space in between 'H' and 'e', in the same word in persian, which is 'سلام', the first letter 'س' is connected to 'ل'. To do this we have to replace the letters with the correct connected symbol to do the trick. Using this approach when applying different fonts to our word, the letters that we replaced with their connected symbol are written in an ugly font. I was wondering if there was an extension or library to install and handle this using GD. Test script: --------------- <?php // Set the content-type header('Content-Type: image/png'); // Create the image $im = imagecreatetruecolor(400, 30); // Create some colors $white = imagecolorallocate($im, 255, 255, 255); $grey = imagecolorallocate($im, 128, 128, 128); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, 399, 29, $white); // The text to draw $text = 'سلام'; $font = 'yekan.ttf'; // Add some shadow to the text imagettftext($im, 20, 0, 11, 21, $grey, $font, $text); // Add the text imagettftext($im, 20, 0, 10, 20, $black, $font, $text); imagepng($im); imagedestroy($im); ?> Expected result: ---------------- When I run the code I expect to see سلام in an image Actual result: -------------- When I run the code I get م ا ل س in an image -- Edit bug report at https://bugs.php.net/bug.php?id=72912&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72912&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72912&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72912&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72912&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72912&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72912&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72912&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72912&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72912&r=support Expected behavior: https://bugs.php.net/fix.php?id=72912&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72912&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72912&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72912&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72912&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72912&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72912&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72912&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72912&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72912&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72912&r=mysqlcfg
