Re: DICOM incorrectly converts background color

ImageMagick's own display tool obviously has the same behaviour as the convert tool, since they use the same codec.

Try (X)MedCon instead. Sante DICOM Viewer and mDicom also display it correctly.

Re: DICOM incorrectly converts background color

Unfortunately, build 6.6.9-7 still produces the same incorrect result on the sample DICOM image (see the original post) :(

DICOM incorrectly converts background color

I have a number of DICOM files (see this one for an example) that I am converting to PNG format. These files have an alpha channel and a white background. The converted PNG files, on the other hand, have black backgrounds. Using ImageMagick 6.6.9-6 2011-04-14 Q16, I simply ran "convert 40267781...

DICOM codec crashes while reading

When reading certain DICOM files (of which this is an example) , the codec crashes in 2 places, both due to dereferencing a null pointer: The following is an excerpt from dcm.c from line 3253 : case 0x1050: { /* Visible pixel range: center. */ window_center=StringToLong((char *) data); break; } case...

Re: DICOM RLE bug causes 4 images in one

While I do not dispute the image being 808x632, I don't see how IM is processing it correctly. Clearly IM is duplicating the image, twice with bytes swapped (top row) and twice with bytes in correct order (bottom row), into parts that are 1/4 size of the original. That is, each new part is 404x316. ...

Re: DICOM RLE bug causes 4 images in one

Thanks for the quick response. Glad to help out with patches (if and when we find them). Our "problem" is that, in spite of the fact that LEADTOOLS writes "bad" files, we need to be able to read them as though they were correct. The patch we submitted goes part of the way towards...

DICOM RLE bug causes 4 images in one

First up, thank you very much for an absolutely fantastic product. We've been using ImageMagick successfully to convert dental X-Ray DICOM images into PNG for easier manipulation. So far so good. However, we have some 16-bit grayscale RLE compressed DICOM images (written by LEADTOOLS software) (e.g....
