Re: [Lazarus] TFPWriterJPEG quality

Because It decrease quality but becuase JPEG is a lossy format its not much important setting this value but its good to have the best value as default. Regards, Ara -- http://www.fastmail.com - Faster than the air-speed velocity of an unladen european swallow --
