    To recover an image saved as RAW, you have to set the color depth first (probably 24), then try widths through trial and error. As you approach the correct width to within a dozen pixels, or an even...

    There are two groups of formats, both called "raw", and have little in common.

    I find that the algorithm choice is mostly dictated by the image content and available CPU speed, not the monitor device. In general, photographs look good with Lanczos or Cubic, which have good...
