I notice that MagickGetImageCompressionQuality returns 0 after formatting a png file to jpg. Is this expected? Thanks.

A compression quality of 0 means undefined compression quality. If you read a JPEG image, the compression quality is set to whatever is returned by the JPEG image. PNG images do not have an associated compression quality.
