FPX-PIL FlashPix

Extensions: .fpx

From the Pillow docs:

PIL reads Kodak FlashPix files. In the current version, only the highest resolution image is read from the file, and the viewing transform is not taken into account.


To enable full FlashPix support, you need to build and install the IJG JPEG library before building the Python Imaging Library. See the distribution README for details.

Parameters for reading

pilmode : str

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_gray : bool
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’.
