private void varyqualitylevel() { // bitmap. bitmap bmp1 = new bitmap(@"c:\testphoto.jpg"); imagecodecinfo jgpencoder = getencoder(imageformat.jpeg);  // create encoder object based on guid // quality parameter category. system.drawing.imaging.encoder myencoder =     system.drawing.imaging.encoder.quality;  // create encoderparameters object. // encoderparameters object has array of encoderparameter // objects. in case, there 1 // encoderparameter object in array. encoderparameters myencoderparameters = new encoderparameters(1);  encoderparameter myencoderparameter = new encoderparameter(myencoder,      50l); myencoderparameters.param[0] = myencoderparameter; bmp1.save(@"c:\testphotoqualityfifty.jpg", jgpencoder,      myencoderparameters);  myencoderparameter = new encoderparameter(myencoder, 100l); myencoderparameters.param[0] = myencoderparameter; bmp1.save(@"c:\testphotoqualityhundred.jpg", jgpencoder,      myencoderparameters);  // save bitmap jpg file 0 quality level compression. myencoderparameter = new encoderparameter(myencoder, 0l); myencoderparameters.param[0] = myencoderparameter; bmp1.save(@"c:\testphotoqualityzero.jpg", jgpencoder,      myencoderparameters);  }  ...  private imagecodecinfo getencoder(imageformat format) {      imagecodecinfo[] codecs = imagecodecinfo.getimagedecoders();      foreach (imagecodecinfo codec in codecs)     {         if (codec.formatid == format.guid)         {             return codec;         }     }     return null; }
