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.

Um, not sure what's the actual issue reported in this ticket.
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.

Hi,
This is happening on PHP 5.3.3 on Linux ( CentOS 5 )
Some letters are overlapped...

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.
