We tried your command on our Intel 3ghz Redhat box with ImageMagick 6.2.5-4 and the command completed in 20.88 seconds. Not sure why its taking so long on your box. You might speed things up a bit if you use the Q8 version of ImageMagick. The default is usually Q16 (16 bits-per-pixel).

You can certainly implement RLE if you want and hopefully contribute the patches back to the ImageMagick distribution. However, you could also post a URL to one or two RLE-compressed DICOM images and we will look into supporting it. We have code for PACKBITs so it should be a simple patch.

Use the convert program with the -crop option to extract a region of an image and save it to another file. Use the -extract option if your input image is in a raw format (e.g. RGB).

Topic: dpi resize bug?
Replies: 4
Views: 30480

The problem is that Photoshop ignores the JPEG/JFIF standard and grabs the DPI not from the image header but from an EXIF profile. ImageMagick does the right thing and sets the JFIF/JPEG resolution in the header but does not modify the EXIF profile. Adobe has had a history of ignoring standards and ...

You are right, warnings should not generate a non-zero status. We will fix the problem in the next ImageMagick release.

ImageMagick has regressions tests which suggest blob support for PDF works. Can you post a code snippet we can try and reproduce the problem. It appears the PDF coders is being called repeatedly.

So far ImageMagick does not not do any color correction to the DNG image. We need to investigate the conversion process more. In the mean-time why not post a URL to your DNG image and the original raw format or in JPEG so we can investigate the problem.

The only other solution is to edit coders/bmp.c to force 8-bit output then recompile/reinstall ImageMagick.

You can force images of 16 colors or less to 8-bit by adding -compress RLE to your command line.
