BICUBIC DOWNSAMPLE PDF

_images has aliasing when downsampling and does not have gradients for bicubic mode. This implementation fixes those problems. To downsample color, grayscale, or monochrome images, choose an interpolation method—average downsampling, bicubic downsampling. Usually, I leave the compression as default which is ‘bicubic downsampling’ to – ppi which give me a MB file, then I decided to.
