      The .PSD (Photoshop Document) format stores an image with support
      for most imaging options available in Adobe Photoshop program.
      These include layers with masks, color spaces,
      ICC profiles, transparency, text, alpha channels, etc.
    </par>
    <par>
      Loading and saving of indexed, grayscale, RGB(A), HDR (FP32), and CMYK
      (auto converted to RGB) images is supported. Non-HDR gray, RGB,
      and CMYK images can have 8bit or 16bit color channels.
      There is no support for loading mono images, duotone images are treated
      like grayscale images, and multichannel and CIE Lab images are loaded as
      RGB images but without actual conversion to RGB color space.
      Also no layer information is loaded.
