Funnily (or not), the png is in fact 8-bits depth so you could infer it is grayscale, but matplotlib is right : your file uses a color palette. The 8-bits values refer to indices of the 256-length color palette. These indices are then converted back to the colorspace, so the shape is eventually (...,3). Unfortunately, the color palette is here the grayscale... -- Fabrice ------------------------------------------------------------------------------ BPM Camp - Free Virtual Workshop May 6th at 10am PDT/1PM EDT Develop your own process in accordance with the BPMN 2 standard Learn Process modeling best practices with Bonita BPM through live exercises http://www.bonitasoft.com/be-part-of-it/events/bpm-camp-virtual- event?utm_ source=Sourceforge_BPM_Camp_5_6_15&utm_medium=email&utm_campaign=VA_SF _______________________________________________ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
