Description:

With the same code, imagefilledrectangle() works.

See the result:
http://haricow.org/gd/rectangle.png

Reproduce code:
---------------
<?php
$image = imagecreatetruecolor(10, 10);

$white = imagecolorallocate($image, 255, 255, 255);

imagerectangle($image, 2, 4, 8, 4, $white);

imagecolordeallocate($image, $white);

header('Content-Type: image/png');
imagepng($image);
?>

Expected result:
----------------
A rectangle.

Actual result:
--------------
A strange shape.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Even if you think it is not a bug, we often know better than you,
please consult the support channels first before even considering
to reopen this report.

Thank you for your interest in PHP.

Seems like you use an external GD.

Please try using the bundled gd (configure --with-gd, not with-gd=/path/to/ext/gd).

Here is my ./configure line :

./configure --enable-debug --with-apxs=/usr/local/apache/bin/apxs --with-xml --with-jpeg-dir --with-png-dir --with-gd --enable-gd-native-ttf --with-freetype-dir --with-zlib-dir --with-openssl --enable-sysvsem --enable-sysvshm --with-xsl --with-mysql --with-pgsql --enable-memory-limit

I use the bundled GD.

Are you sure you do not have any gd-devel package installed?

If yes, remove/move them before running configure and make.

Recompiling PHP with:
make clean
./configure --with-apxs=/usr/local/apache/bin/apxs --with-jpeg-dir --with-png-dir --with-gd --enable-gd-native-ttf --with-freetype-dir --with-zlib-dir
make
make install

I removed all GD libraries:
[root@localhost php5-STABLE-200502101130]# rpm -qa | grep gd
libgdk-pixbuf2-0.22.0-5mdk
ifplugd-0.25-1mdk
sysklogd-1.4.1-6mdk
gdk-pixbuf-loaders-0.22.0-5mdk
gdb-6.2-2mdk
libgdk_pixbuf2.0_0-2.4.9-9mdk
libgdk-pixbuf-gnomecanvas1-0.22.0-5mdk
libgdbm2-1.8.0-25mdk


The problem is still here...
 [2005-02-28 12:14 UTC] pajoye@php.net 
Please try using "Latest CVS (5.1.x-dev)" snapshot

Works as expected with 5.1.x dev.


merci :)
