Legacy ImageMagick Discussions Archive

I've encountered an issue with recently released version IM 7.0.7-17 Q16 x64 HDRI on Windows 10 64. If I run this command...
I get this error...
I can avoid the error by specifying the MIFF format when reading the data from the pipe if I modify the command like this...
But using "MIFF:-" to read the output of the pipe was not necessary in previous versions.

This works fine for me on IM 7.0.7.17 Q16 HDRI Mac OSX Sierra

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ https://www.imagemagick.org/download/beta/ by sometime tomorrow.
