.. _WMF-PIL:
WMF-PIL Windows Metafile
========================
Extensions: ``.wmf``, ``.emf``
*From the Pillow docs:*
PIL can identify playable WMF files.
In PIL 1.1.4 and earlier, the WMF driver provides some limited rendering
support, but not enough to be useful for any real application.
In PIL 1.1.5 and later, the WMF driver is a stub driver. To add WMF read or
write support to your application, use
:py:func:`PIL.WmfImagePlugin.register_handler` to register a WMF handler.
::
from PIL import Image
from PIL import WmfImagePlugin
class WmfHandler:
def open(self, im):
...
def load(self, im):
...
return image
def save(self, im, fp, filename):
...
wmf_handler = WmfHandler()
WmfImagePlugin.register_handler(wmf_handler)
im = Image.open("sample.wmf")
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'.
