4 tR# )ag Read/Write images using FreeImage.
Backend Library: `FreeImage `_
.. note::
To use this plugin you have to install its backend::
imageio_download_bin freeimage
or you can download the backend using the function::
imageio.plugins.freeimage.download()
Each Freeimage format has the ``flags`` keyword argument. See the `Freeimage
documentation `_ for more information.
Parameters
----------
flags : int
A freeimage-specific option. In most cases we provide explicit
parameters for influencing image reading.

c D ] tR t^tRt ! R R]P 4 tRtR# )FreeimageBmpFormataz A BMP format based on the Freeimage library.
This format supports grayscale, RGB and RGBA images.
The freeimage plugin requires a `freeimage` binary. If this binary
not available on the system, it can be downloaded manually from
by either
- the command line script ``imageio_download_bin freeimage``
- the Python method ``imageio.plugins.freeimage.download()``
Parameters for saving
---------------------
compression : bool
Whether to compress the bitmap using RLE when saving. Default False.
It seems this does not always work, but who cares, you should use
PNG anyway.

Parameters for reading
----------------------
ignoregamma : bool
Avoid gamma correction. Default True.
Parameters for saving
---------------------
compression : {0, 1, 6, 9}
The compression factor. Higher factors result in more
compression at the cost of speed. Note that PNG compression is
always lossless. Default 9.
quantize : int
If specified, turn the given RGB or RGBA image in a paletted image
for more efficient storage. The value should be between 2 and 256.
If the value of 0 the image is not quantized.
interlaced : bool
Save using Adam7 interlacing. Default False.

a A JPEG format based on the Freeimage library.
This format supports grayscale and RGB images.
The freeimage plugin requires a `freeimage` binary. If this binary
not available on the system, it can be downloaded manually from
by either
- the command line script ``imageio_download_bin freeimage``
- the Python method ``imageio.plugins.freeimage.download()``
Parameters for reading
----------------------
exifrotate : bool
Automatically rotate the image according to the exif flag.
Default True. If 2 is given, do the rotation in Python instead
of freeimage.
quickread : bool
Read the image more quickly, at the expense of quality.
Default False.
Parameters for saving
---------------------
quality : scalar
The compression factor of the saved image (1..100), higher
numbers result in higher quality but larger file size. Default 75.
progressive : bool
Save as a progressive JPEG file (e.g. for images on the web).
Default False.
optimize : bool
On saving, compute optimal Huffman coding tables (can reduce a
few percent of file size). Default False.
baseline : bool
Save basic JPEG, without metadata or any markers. Default False.

a Use Orientation information from EXIF meta data to
orient the image correctly. Freeimage is also supposed to
support that, and I am pretty sure it once did, but now it
does not, so let's just do it in Python.
Edit: and now it works again, just leave in place as a fallback.
