No docs for DIB. Parameters for reading ———————-

pilmodestr

  From the Pillow documentation:

  - ‘L’ (8-bit pixels, grayscale)

  - ‘P’ (8-bit pixels, mapped to any other mode using a color palette)

  - ‘RGB’ (3x8-bit pixels, true color)

  - ‘RGBA’ (4x8-bit pixels, true color with transparency mask)

  - ‘CMYK’ (4x8-bit pixels, color separation)

  - ‘YCbCr’ (3x8-bit pixels, color video format)

  - ‘I’ (32-bit signed integer pixels)

  - ‘F’ (32-bit floating point pixels)

  PIL also provides limited support for a few special modes, including ‘LA’ (‘L’ with alpha), ‘RGBX’ (true color with padding) and ‘RGBa’ (true color with premultiplied alpha).

  When translating a color image to grayscale (mode ‘L’, ‘I’ or ‘F’), the library uses the ITU-R 601-2 luma transform:

      L = R * 299/1000 + G * 587/1000 + B * 114/1000

as_graybool

  If True, the image is converted using mode ‘F’. When mode is not None and as_gray is True, the image is first converted according to mode, and the result is then “flattened” using mode ‘F’.
