libPNG or not in phpinfo()

[Acoon]

So, I got a weird problem with my .png images in GD.

Some look all screwed up and wrong sizes etc. But only the ones that is transparent. Regular png images with no blending works fine. I have this problem on my server.

 

However, on my workstation i have easyPHP with PHP, apache, mysql etc for developing. There it works. They both has png support as shown in phpinfo():

PNG Support 	enabled 

 

And they are both GD version 2.0.34 compatible. The only real difference i can see is that on my workstation i have an extra line in GD in phpinfo().

 

libPNG Version 	1.2.44 

 

So my question is, what does this mean in regards to functionality?

You probably don't have libPNG installed on your server. GD should support PNG out of the box, but the support is pretty meh from what I've read. libPNG is probably the solution.

Thanks for your reply.

 

It seems libpng is already installed on the server. Any idea on how to 'enable' it in php?

[root@vps1 ~]# yum install libpng.x86_64
Package 2:libpng-1.2.10-7.1.el5_5.3.x86_64 already installed and latest version
Nothing to do

Check your Configure Command in PHP info.

 

Also check print_r( gd_info() );

 

Or try compiling with --with-png-dir=/usr/local

Same on both computers...

There could be an error loading libPNG. It's obviously there, but PHP might not know where it is. I've heard about issues using relative paths.

 

Not sure how I can help beyond making sure you've compiled with --with-png-dir=/dir/to/libPNG
