Description

Code sample:

Map<String, Object> params = new HashMap<>();
params.put(PnmImageParser.PARAM_KEY_PNM_RAWBITS, PnmImageParser.PARAM_VALUE_PNM_RAWBITS_YES);
Imaging.writeImage(image, file, ImageFormats.PNM, params);

Error message is: "Unknown parameter: PNM_RAWBITS:

This happens because used parameters are cleared from the map after usage and any remaining parameters are determined to be unknown, but PnmImageParser.PARAM_KEY_PNM_RAWBITS is never cleared.

I will provide a patch on Github shortly.
