Hello all.
I'm pretty new to Imagick. I'm merely attempting the examples on the
PHP site (http://php.net/manual/en/imagick.examples-1.php), but I'm
having some issues. I'm attempting the reflection of an image
example and when I attempt to:
$canvas->setImageFormat("png");
I get an error that reads:
Fatal error: Uncaught exception 'ImagickException' in /home/www/pc4/
image.php:67 Stack trace: #0 /home/www/pc4/image.php(67): Imagick-
>setimageformat('png') #1 {main} thrown in /home/www/pc4/image.php
on line 67
Note that I CAN do this: $canvas->setImageFormat("gif");
I'm running Fedora Core 8. My first thought was that my machine
doesn't support PNG. So I checked for libpng, and it's there and up
to date. I've looked at my http error logs and I've google'd to no
avail. Do you have any thoughts on why I can't use the "png" format?
Thanks in advance,

Ok, I figured it out. Along with that error message I was receiving
"identify: no decode delegate for this image format" when I attempted
to open up a PNG image. Well, after some searching, I discovered that
that basically means you don't have the libraries to support that
image type. The weird part is, I did have libpng. However, I think I
may have installed it after I built ImageMagick. So, I rebuilt
ImageMagick. This time I looked at the configuration and png support
was enabled. It works now! Yay!
This person was having a similar issue and it helped me figure out
what I need to know:

Also, directions for installing ImageMagick from source:
