|

|
Converts the multi-array to a CGImage.
|
||||||
|
The multi-array must have at least 2 dimensions for a grayscale image, or
|
||||||
|
at least 3 dimensions for a color image.
|
||||||
|
The default expected shape is (height, width) or (channels, height, width).
|
||||||
|
However, you can change this using the `axes` parameter. For example, if
|
||||||
|
the array shape is (1, height, width, channels), use `axes: (3, 1, 2)`.
|
||||||
|
If `channel` is not nil, only converts that channel to a grayscale image.
|
||||||
|
This lets you visualize individual channels from a multi-array with more
|
||||||
|
than 4 channels.
|
||||||
|
Otherwise, converts all channels. In this case, the number of channels in
|
||||||
|
the multi-array must be 1 for grayscale, 3 for RGB, or 4 for RGBA.
|
||||||
|
Use the `min` and `max` parameters to put the values from the array into
|
||||||
|
the range [0, 255], if not already:
|
||||||
|
- `min`: should be the smallest value in the data; this will be mapped to 0.
|
||||||
|
- `max`: should be the largest value in the data; will be mapped to 255.
|
||||||
|
For example, if the range of the data in the multi-array is [-1, 1], use
|
||||||
|
`min: -1, max: 1`. If the range is already [0, 255], then use the defaults.
