Read entire image
imageData = read(tiffobj)
[Y,Cb,Cr] = read(tiffobj)
imageData = read(tiffobj) reads the image data from the current image file directory (IFD) in the TIFF file associated with the Tiff object, tiffobj.
[Y,Cb,Cr] = read(tiffobj) reads the YCbCr component data from the current directory in the TIFF file. Depending upon the values of the YCbCrSubSampling tag, the size of the Cb and Cr channels might differ from the Y channel.
Open a Tiff object and read data from the TIFF file:
t = Tiff('example.tif','r'); imageData = read(t); close(t)
