png32:- works, png:- doesn't

I've installed IM 6.7.9-0 from source on CentOS6.
One thing which stands out is that I have made sure I have libpng15 installed in the /usr/lib64 dir but during execution of the configuration script it shows:
Code: Select all
checking for LIBPNG15 support ... no
..which forces it to use the already present libpng12.
Then whenever i use png:- as output format a no encode delegate error is thrown. The error is only occured when executing the command without a shell environment. Also the png32:- output format works ok even without shell.
Any idea why the plain png:- output won't work for me when no shell environment is present?

That's odd. Have you verified that the output is actually in PNG32 format?

glennrp, I'm not completely sure that's the case. You can see the output here:
The resulting image has transparency and is returned with a Content-type: image/png so i think the browser interprets it like such.
I remember seeing somewhere that the png32:- delegate uses a different library than the png:- format. Maybe something causes the libpng library to break with no shell evironment.
Here is the base64 encoded output of the image:

I examined it with "identify -verbose"
- IHDR chunk data:
Width=221, height=18
Bit depth =8
Color type=6
Interlace =0
Properties:
png:IHDR.bit_depth : 8
png:IHDR.color_type : 6 (RGBA)
The Color type (6) and Bit depth (8) are those of a PNG32.

Yes, that's the working png32:- delegate. When i use just png:- it throws the no encode delegate error. Here is the php code i call the convert program with:
Code: Select all
$format = 'jpg:-';
switch($options['format']) {
case 'png' :
$format = 'png32:-';
break;
default:
$format = 'jpg:-';
break;
}
$IMCommand = BIN_PATH.'convert ';
$IMCommand .= ' -size '.$options['X'].'x'.$options['Y'].' ';
$IMCommand .= ' -background transparent ';
$IMCommand .= ' -fill white ';
$IMCommand .= ' -stroke none ';
$IMCommand .= ' -gravity center ';
$IMCommand .= ' -trim ';
$IMCommand .= ' -font '.FONTS_PATH.DIRECTORY_SEPARATOR.escapeshellarg($options['font']).' ';
$IMCommand .= ' label:"'.escapeshellarg($options['text']).'" ';
$IMCommand .= ' '.$format.' ';
$descriptorspec = array();
switch($pipenum) {
case 1 :
$descriptorspec = array(
1 => array("pipe", "w")
);
break;
case 3 :
$descriptorspec = array(
0 => array("pipe", "r"),
1 => array("pipe", "w"),
2 => array("pipe", "w")
);
break;
default :
$descriptorspec = array(
1 => array("pipe", "w"),
2 => array("pipe", "w")
);
break;
}
$process = proc_open($IMCommand, $descriptorspec, $pipes);
$add = '';
$error = '';
if (is_resource($process)) {
if($pipenum > 2) {
fwrite($pipes[0], $input);
fclose($pipes[0]);
}
while (!feof($pipes[1])) {
$add .= fgets($pipes[1]);
}
fclose($pipes[1]);
if($pipenum > 1) {
while (!feof($pipes[2])) {
$error .= fgets($pipes[2]);
}
fclose($pipes[2]);
}
$return_value = proc_close($process);
}

I don't see anything inside coders/png.c (RegisterPNGImage(()) that would explain why
PNG32 works and PNG doesn't.
Does "convert -list delegate" give any hint?

Just a clarification - I tried running procopen() on a shell script using png:- for output instead of just the command to simulate a shell environment. It worked! Below are the delegates.xml and configure.xml contents as run from proc_open on imagemagick's convert. It'd be really nice if i can get aound using a shell script but running IM commands directly through proc_open.

In utter dismay I report the problem having vanished all of a sudden! That's the strangest issue i've ever had to deal with. i just replaced png32:- with png:- and now it's working like a charm. Just like that. I have a feeling the problem will be back though. I'll continue the thread when i start getting that error again.
Here's the latest output using the plain png:- output:

Might you have accidentally type a long or short hyphen with png:-? That might account for it.

My first thought was that my syntax is wrong. That's why i made the php output the command to the browser instead of the image. Then copy/pasted from the browser into bash and it all worked there but not in proc_open. It's all working now. I'm using Komodo and i'm not sure if i can add a long dash with the kbd into it. Thanks for your involvement in the problem though.
