Bug #50194 [Asn->Ana]: imagettftext broken on transparent background w/o alphablending

Edit report at https://bugs.php.net/bug.php?id=50194&edit=1 ID: 50194 Updated by: cmb@php.net Reported by: stanislav at ww9 dot ru -Summary: With some fonts, letters are overlapped with imagettftext +Summary: imagettftext broken on transparent background w/o alphablending -Status: Assigned +Status: Analyzed Type: Bug Package: GD related Operating System: Windows PHP Version: 5.2.11 Assigned To: cmb Block user comment: N Private report: N New Comment: The problem is that the background of the character glyphs must not be drawn, and actually, this issue has already been fixed as of GD 2.0.26[1], but that fix never made it to PHP's bundled libgd. I'm going to port the fix.

Unfortunately, most of the links to results, fonts, etc. in this report and in #50958 are unavailable in the meantime. I can reproduce overlapping (respectively insufficient horizontal letter distance) as reported by alvaro with PHP 5.3.2, but this has been fixed as of PHP 5.4.0, if not earlier. However, the original supplied test script gives indeed completely broken results due to imagealphablending($im, false); even on recent versions (PHP 5.6.11 and 7.0.0beta1) and apparently not related to the font. See <http://imgur.com/UPowpes>. I'll try to investigate. ------------------------------------------------------------------------ [2010-09-21 21:10:29] brunofgaspar at live dot com dot pt Sorry for double post, but i forgot to include examples Linux: http://img836.imageshack.us/i/linuxr.png/ Windows: http://img829.imageshack.us/i/windowsy.png/ ------------------------------------------------------------------------ [2010-09-21 21:06:52] brunofgaspar at live dot com dot pt Hi, This is happening on PHP 5.3.3 on Linux ( CentOS 5 ) Some letters are overlapped... ------------------------------------------------------------------------ [2010-04-29 12:46:48] rezny at pharmdata dot cz There is already a solution for this problem in svn for both 5.2 and 5.3 branches (submited by tabe more than 5 weeks ago) - look for the file gdft.c . I suppose that this bug can be closed now. ------------------------------------------------------------------------ [2010-04-23 10:21:05] rezny at pharmdata dot cz Seems that imagefttext is affected too, resulting image looks exactly the same. Does it use the same library? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
