Error reading from pipe with IM 7.0.7-17

[GeeMack]

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...

Code: Select all

magick logo: MIFF:- | magick - test.png

I get this error...

Code: Select all

magick: improper image header `-' @ error/miff.c/ReadMIFFImage/1092.

I can avoid the error by specifying the MIFF format when reading the data from the pipe if I modify the command like this...

Code: Select all

magick logo: MIFF:- | magick MIFF:- test.png

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

Code: Select all

magick logo: MIFF:- | magick - test.png
