[Mapserver-users] mapscript::msSaveImage error

[Pedro Salazar]

Greetings,

I'm trying to return a image map in my perl mapscript. However, when I
use the procedure msSaveImage, I got an error on my map script log and
no image return on my perl script.

This is my code:
"
my $ref_img = $map->drawReferenceMap();
mapscript::msSaveImage($ref_img,undef,$mapscript::MS_PNG,
       $map->{transparent},$map->{interlace},undef);
"

This is my error output:
"
Tue May 20 14:29:57 2003 - msSearchDiskTree(): Unable to access file. 
Tue May 20 14:29:57 2003 - msSearchDiskTree(): Unable to access file. 
Tue May 20 14:29:57 2003 - msDrawReferenceMap(): Unable to access file.
((null))
"

I managed a workaround to solve my problem doing this but I would like
to avoid this approach:
"
my $tmp_file="/tmp/".rand().".png";
$img->saveImage($tmp_file,$mapscript::MS_PNG, $map->{transparent},
                $map->{interlace}, undef);
system("cat $tmp_file");
system("rm -f $tmp_file");
"

So, I'm interested to know why is that happening (error) and how can I
solve it.

Thanks for all your attention,
Pedro.
