Public bug reported: When using an Imagemagick compiled with HDRI=1 (e.g., ,libmagickwand-6.q16hdri-6) many color-related test cases in wand fail.
The root cause is that python-wand assumes that ImageMagick's QuantumType would be float for 16-bit HDRI. However, in that config QuantumType is derive from float_t, which on s390x today is defined as double. The upstream issue https://github.com/emcconville/wand/issues/504 has already been resolved. The fix will be included in the upcoming release 0.6.4. Please consider upgrading to the new release, once available. Upstream fix in PR https://github.com/emcconville/wand/pull/505 The issue can be reproduced by running the testsuite (pytest / pytest-3). ** Affects: wand (Ubuntu) Importance: Undecided Status: New ** Description changed: When using an Imagemagick compiled with HDRI=1 (e.g., ,libmagickwand-6.q16hdri-6) many color-related test cases in wand fail.
