title: downscale large 1 bit tiff to 8 bit grayscale / 24 bit
body: <p>Let's say i have a 100000x100000 1 bit (K channel) tiff with a dpi of 2000 and i want to downscale this to a dpi of 200. My resulting image would be 10000x10000 image. Does this mean that every 10 bits in the 1 bit image correspond to 1 pixel in the new image? By the way, i am using libtiff and reading the 1 bit tiff with tiffreadscanline. Thanks!</p>
