| Parameters: |
- fname : str or PathLike or file-like
A path or a file-like object to store the image in.
If format is not set, then the output format is inferred from the
extension of fname, if any, and from rcParams["savefig.format"] (default: 'png') otherwise.
If format is set, it determines the output format.
- arr : array-like
The image data. The shape can be one of
MxN (luminance), MxNx3 (RGB) or MxNx4 (RGBA).
- vmin, vmax : scalar, optional
vmin and vmax set the color scaling for the image by fixing the
values that map to the colormap color limits. If either vmin
or vmax is None, that limit is determined from the arr
min/max value.
- cmap : str or
Colormap, optional
A Colormap instance or registered colormap name. The colormap
maps scalar data to colors. It is ignored for RGB(A) data.
Defaults to rcParams["image.cmap"] (default: 'viridis') ('viridis').
- format : str, optional
The file format, e.g. 'png', 'pdf', 'svg', ... The behavior when this
is unset is documented under fname.
- origin : {'upper', 'lower'}, optional
Indicates whether the (0, 0) index of the array is in the upper
left or lower left corner of the axes. Defaults to rcParams["image.origin"] (default: 'upper')
('upper').
- dpi : int
The DPI to store in the metadata of the file. This does not affect the
resolution of the output image.
