"""Generate an image with the passed in settings
This is used by :func:`resize` and is run outside of the Flask context.
Args:
inpath (str):
Path to the image to generate a new image out of.
outpath (str):
Where the new image will end up.
width (Optional[:class:`int`]):
The width to use for the generated image.
height (Optional[:class:`str`]):
The height to use for the generated image.
format (str):
Format to convert into. Defaults to "JPEG".
fill (bool):
Fill the entire width and height that was specified if True,
otherwise keep the original image dimensions. Defaults to False.
upscale (bool):
Whether or not to allow the image to become bigger than the
original if the request width and/or height is bigger than its
dimensions. Defaults to True.
anchor (str):
Deprecated since Flask-Resize 0.6.
quality (int):
Quality of the output image, if the format is JPEG. Defaults to 80.
bgcolor (Optional[:class:`str`]):
If specified this color will be used as background.
progressive (bool):
Whether to use progressive encoding or not when JPEG is the
output format.
force_cache (bool):
Whether to force the function to always use the image cache. If
false, will reaise a :class:`exc.StopImageGeneration` if the
generated image would be the same as the original. Defaults to
False.
placeholder_reason (Optional[:class:`str`]):
A text to show the user if the image path could not be found.
placeholder_image_path (Optional[:class:`str`]):
The path to the image to use as the background of the placeholder.
Raises:
:class:`exc.ImageNotFoundError`:
If the source image cannot be found or is not a file.
:class:`exc.StopImageGeneration`:
If force_cache is False and if the image transformation would
result in the same image as the original.
