| GetOriginalOptions |
Gets the options based on the original file settings.
This can be helpful to keep bit-depth and other parameters of the original image unchanged.
For example, if we load a black-white PNG image with 1 bit per pixel and then save it using the
Save(String) method, the output PNG image with 8-bit per pixel will be produced.
To avoid it and save PNG image with 1-bit per pixel, use this method to get corresponding saving options and pass them
to the Save(String, ImageOptionsBase) method as the second parameter.
