Hello. I am trying to crop images but not change the DPI.. Whgat I am seeing is an image is 200dpi and then after I perform the crop, the cropped output is 72 dpi.. My code looks like this...

my $imageCrop = $image->Clone();

$imageCrop->Crop( $pixelsWide . "x" . $pixelsHigh . "+" . abs($pixelsLeft) . "+" . abs($pixelsTop) );

$result = $imageCrop->Write("$TempDir$file");

This is having a huge impact for my process so any help would be appreicated.

Thanks, Scott.

I had this issue generating gif images. Any other format, jpeg, etc., should work fine.

Seems to work fine in command line mode, IM 6.7.7.3 Q16 Mac OSX Snow Leopard

identify -verbose logo_tmp.png

nothing you do is changing the DPI resolution of the images. Perhaps the image file format does not allow it?
