bug when converting DPX files?

Post by aberkl »

I am running ImageMagick 6.5.4-6 2009-07-25 Q16 on Windows XP.

I noticed whenever I convert from a DPX file to another format (or to DPX again) i.e.

Code: Select all

convert chart.dpx chart_converted1.jpg
I get
a) random (?) black horizontal lines in the resulting image and
b) partly reduced (half) vertical resolution (see diagonal lines in sample images http://www.berkl.de/stuff/dpx2jpeg.jpg)

When running convert a second time

Code: Select all

convert chart.dpx chart_converted2.jpg
with the same DPX file as input the results for chart_converted1.jpg and chart_converted1.jpg are different.

I have uploaded the original DPX file and 8 JPEG-clones here: http://www.berkl.de/stuff/dpx2jpeg.zip

The bug is likely in Microsoft's implementation of OpenMP. In the next release we will turn off OpenMP in the DPX coder. Look for it in a few days and let us know if that fixes the problem.

Just noticed I should have mentioned it explicitly: Yes, it works perfect now! Thanks again.
