Try this. In pdf_sp.inc add "-alpha deactivate" as in here:

$cmdline = "/usr/local/bin/convert \"$file\"\[0\] -alpha deactivate -colorspace RGB -thumbnail $width" . "x$height \"$file$file_suffix\"";

(two instances)

My version of Islandora is older. You should be able to search for "convert" string in all files of your Islandora directory tree.

spechial thanks to Serhiy,

finally i can solve the problem with this method:

you must go in this path and do this:

/sites/all/modules/islandora_solution_pack_pdf/includes

in islandora_pdf_create_jpg_derivative function add this:

$args['alpha'] = '-alpha remove ';

and change png to jpg in $command line, like this:

$command = escapeshellarg($source) . ' ' . implode(' ', $args) . ' ' . escapeshellarg("png:$dest");
