Both imshow() and set() are failed. Here is my code:
>> im = imread('white_background.png');
>> imshow(im)
error: imshow: TrueColor image must be uint8, uint16, double, or single
error: called from
    imshow at line 114 column 7
>> img = image();
>> set(img, 'cdata', im)
>> warning: opengl_texture::create: invalid image data type, expected double,
single, uint8, or uint16
