Can't provide just one keyword argument to save

[daveliepmann]

I get an IllegalArgumentException when I attempt to use imagez's save function with exactly one keyword argument.

Example

I require version 0.12.0 of the library with [mikera.image.core :as imgz] and have the image and file system path defined as img and path respectively.

Specifying no keyword arguments with (imgz/save img path) works fine.

Specifying both keyword arguments with (imgz/save img path :quality 0.5 :progressive false) or (imgz/save img path :quality 0.5 :progressive nil) also work fine.

However, (imgz/save img path :quality 0.5) causes:

Unhandled java.lang.IllegalArgumentException
No value supplied for key: [:quality 0.5]

and (imgz/save img path :progressive false) causes:

Unhandled java.lang.IllegalArgumentException
No value supplied for key: [:progressive false]
