Public methodGetModifyDate
Gets the date and time the resource image was last modified.
Public methodGetOriginalOptions
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.
