[maplab-users] Error in msSaveImage(): GIF Output is not available

[Paul Spencer]

Vincenzo,

I am a little confused about where the red Xs are ... I think you mean 
that GIF is not supported by MapScript (but PNG is for example?).  For 
PHP, are no image types supported?  Or just not GIF?

On windows, PHP does not support GIF by default and I think you'd have 
to compile your own php_gd.dll to get it.  On Linux, you probably build 
your own GD then it's up to you if GIF is included.   But this will 
likely affect both PHP and MapScript so if it's available in one it 
should be in the other unless you are using two different GDs for PHP 
and MapScript.  In either case, you should be able to work with PNG 
images.

see my post just now about how the preview.php file may need to be 
changed.  The default mapfile doesn't include an image type and so 
defaults to GIF.  You should explicitly change it to PNG in the map 
object.  Also, I think you need to put the image type in the 
configuration files to PNG.

Cheers,

Paul
