I'm cropping animated GIFs and the result of some of them is incorrect. Everything I've found says that setting the Page should fix it but it doesn't.

Source Image:

Result Image: (Note the extra transparent area)

I've tried:
- setImagePage before coalesceImages
- setImagePage after deconstructImages
- using the setPage function
- Saving the image, loading it again and recropping it (does nothing)
- doing setImagePage(0, 0, 0, 0)
- doing setImagePage(null, null, null, null)

Notes:
- If I also resize the result smaller, things work fine.
- ImageMagick claims the resulting image is the right size.

ImageMagick Version: ImageMagick 6.7.5-3 2012-02-24 Q16 http://www.imagemagick.org
PHP Extension Version (Gentoo package): dev-php/pecl-imagick version 3.0.0-r1
OS: Gentoo

Edit://Oops.

I did some testing with the command line tools which I had never used before and was able to get a good image as well as duplicate the results that Imagick is creating.

This one works fine, creates the desired results:

Code: Select all

convert haters-owl.gif -coalesce -crop 100x100+25+25\!  console_test.gif

This one creates an animated gif with extra transparent area on the right and bottom sides:

Code: Select all

convert haters-owl.gif -coalesce -crop 100x100+25+25\! -layers OptimizePlus  console_test.gif

I used the same file in the example in the last post.

this sounds similar to the problem reported at viewtopic.php?f=1&t=20227&p=80411&hilit ... ize#p80392. See the whole set of replies, esp, from Anthony. You may need to upgrade your IM version.

Try setimagepage().

Relevent code:

Code: Select all

$image = new Imagick($_SESSION[path]);

##################
if ( $_GET[action] == "Crop" ) 
   {  
    foreach ($image as $frame)
    { $frame->cropimage( $w, $h, $ul_x, $ul_y); }
   }
##################
# Reset geometry
foreach ($image as $frame)
 { $frame->setimagepage( $w, $h, 0, 0); }

I use setImagePage, and have tried it everywhere. As I have it now, it does do what its supposed to MOST of the time.
