Imwrite 16bit

WebJun 16, 2024 · 3 If I create, say, a = np.random.randint (0, 65536, size= (48, 48, 3)).astype (np.uint16) and then run cv2.imwrite ('foo.png', a), I get a 16 bit RGB file. If instead I use a = np.random.randint (0, 65535, size= (48, 48)).astype (np.uint16), I get a 16 bit grayscale image. In other words, cv2.imwrite () works for me. Webimwrite(X,map,filename,fmt)writes the indexed image in Xand its associated colormap mapto filenamein the format specified by fmt. If Xis of class uint8or uint16, imwritewrites the actual values in the array to the file. If Xis of class double, the imwritefunction offsets the values in the array before writing, using uint8(X-1).
