TIF files permit a variety of different compression methods, and I believe that Image::Magick supports all (or at least most) of them.
Image::Magick also supports many other graphics formats.
So if you are happy with (lossy) JPEG compression, why not use a JPEG file, which supports only that type of compression? Or use a TIF file with JPEG compression? Why try to invent JPEG compression in a GIF file? Do you have some particular reason to need a GIF file for some purpose? If you must have GIF, you are stuck with its capabilities and limitations.
On approximately 2/25/2004 1:01 AM, came the following characters from the keyboard of John:
Unfortunately, Image::Magick doen't support gif compression.
Here is my script
use Image::Magick;
my $image;
$image = Image::Magick->new;
$image->Read('test.bmp'); $image->Resize(geometry=>'800x800'); $image->Write(filename=>'test.gif', compression => 'JPEG', quality=>1, monochrome =>True);
the 10MB bmp can be compressed to 100KB jpg (with 800x800 geometry)
Any more effective compression?

Sure, use Image::Magick

Has anyone compressed and convert a bmp image through the perl?
Thanks in advance.
