I believe that darktable is correct according to “Testing Other OpenEXR Viewers” (https://www.openexr.com/documentation/OpenEXRViewers.pdf page 4): “The image should be cropped for files where the data window extends outside the display window, and padded with pixels of an appropriate background color for files where the display window extends outside the data window.”
(As a side note, GIMP’s handling of OpenEXR is broken in other ways, for example it doesn’t interpret alpha as premultiplied like it should.) The “Technical Introduction to OpenEXR” (https://www.openexr.com/documentation/TechnicalIntroduction.pdf) says on page 6 that “For most images, in particular finished frames that will be delivered to the customer, the data window is the same as the display window, but for some images that are used in producing the finished frames, the data window differs from the display window.” Could we then consider setting the display window to the data window? If, as you say, the data window already contains exactly the data that is supposed to be displayed, then I don’t really see a reason not to (correct me if I am wrong). It would make all the aforementioned software agree. -- You received this bug notification because you are a member of Hugin Developers, which is subscribed to Hugin. https://bugs.launchpad.net/bugs/1865333 Title: dataWindow and displayWindow look swapped in generated OpenEXR files Status in Hugin: Opinion Bug description: When exporting a high dynamic range image with a crop as an OpenEXR file, the cropped dimensions end up as the dataWindow and the canvas size as the displayWindow, which seems like it’s the wrong way around. When imported back into darktable, the image has a black border on the left and at the top. Export settings: https://i.imgur.com/TFmA6zP.png (also attached) exrheader output: dataWindow (type box2i): (51 78) - (5292 3991) displayWindow (type box2i): (0 0) - (5345 4070) This happens on intermediary remapped files too, not just the final merged output.
