Your OrthoViewLite code is fantastic!!! Many thanks!! So I tested many .tif images. Some open, some others not. When .tif images do not open, the terminal shows me this message:
Error:[ WARN:0] global /tmp/pip-req-build-h2062vqd/opencv/modules/imgcodecs/src/grfmt_tiff.cpp (457) readData OpenCV TIFF: TIFFRGBAImageOK: Sorry, can not handle images with 32-bit samples
no image!
