Hi folks, first post on here but am no stranger to programming so i hope you guys can help me out!

I am converting DICOM files to png format but I only get a gray image with a very faint outline of the original image.
(Btw DICOM images are the what comes off an MRI machine and other medical imagery machines)

So I am using PHP to run the scripts.

$image_details = `convert dicom_tests\IM3 dicom_tests\IM3_convert.png`;

but that gives me

which as you can tell - isn't like

which was converted in Photoshop.

Am I missing something really obvious or do I need to change a setting somewhere?!
If you need the header information, let me know as it's rather lengthy!

TiA for any advice and assistance,

Spike

A typing error as you do not have an original file extension ?

oooh, one sec and I will try that

Add -normalize to your command line. If that fails, post a URL to your image so we can download an reproduce the problem.

no difference I'm afraid.

Interestingly comparing the histograms for the 2 images there are some stark differences. Just as a snippet

FAN-BLUMMIN-TASTIC!
Thanks magick, what does -normalise do then? (I know I can RTFM but it is easier to just ask!)
