How to open/load image .tiff files > 2 GB ?

[hobbyist]

I tried opencv in order to open/load huge image .tiff files without success... Is there any other way?

Error:
WARN:0] OpenCV TIFF: TIFFRGBAImageOK: Sorry, can not handle images with 64-bit samples
Error!
imread_('/home/hobbyist/Desktop/code/IMAGES/UAV_image.tif'): can't read data: OpenCV(3.4.14) /tmp/pip-req-build-m7h7rfem/opencv/modules/imgcodecs/src/grfmt_tiff.cpp:483: error: (-215:Assertion failed) ((uint64_t)tile_width0 * tile_height0 * ncn * std::max(1, (int)(bpp / bitsPerByte)) < MAX_TILE_SIZE) && "TIFF tile size is too large: >= 1Gb" in function 'readData'

you could convert the image to a lower resolution by using an online sizer.
There are many available, google 'resize image online'

If you want to view the image on your system, you will have to add more memory.
