pyrecoil

pyrecoil provides Python bindings to RECOIL, the Retro Computer Image Library, allowing you to open over 500 image file formats from retro computers.

Installation

pip install pyrecoil

pyrecoil is most useful when installed in conjunction with Pillow, the active fork of the Python Image Library:

pip install Pillow

Usage

from recoil import RecoilImage

# load image from disk and decode it:
img = RecoilImage("foo.lbm")

# load image from an existing file handle:
# (filename must still be provided, as a hint to the decoder)
img = RecoilImage("foo.lbm", f)

# inspecting properties:
img.colors  # number of colors used in the image
> 16

img.frames  # number of alternating frames (used for 'interlace' / 'gigascreen' effects)
> 1

img.size  # return a tuple of (width, height)
> (320, 200)

img.original_size  # for images that have been resized to account for non-square pixels
> (320, 200)

img.platform
> 'Amiga'

# Retrieving pixel data -
# returns a bytearray consisting of three bytes (r, g, b) for each pixel,
# in left-to-right, top-to-bottom order
pixels = img.get_pixels()

# convert to a PIL / Pillow image object:
pil_image = img.to_pil()
pil_image.save('foo.png')

Build notes

The RECOIL library itself is implemented in the Fusion Programming Language. For ease of distribution, the generated C output (recoil.c and recoil.h) from the fut transpiler is included in the package - this, along with recoil_interface.c, forms the Python extension module.
