Hi everybody !
I've got a problem with my first perl script using imagemagick:
I've got a sequence of tiff frame and I want to get the bitdepth of each.
Extract of my script:
$image = Image::Magick->new;
$image->Read($complete_file_name);
$file_bitdepth = $image->Get('depth');
I get for some frames the correct bitdepth: 16 but also some frames a 9 !!
If I check with tiffinfo, here is the result:
The first frame getting a depth of 16 in IM
