Internally + * we multiply these, so that the generated pdf will render at the + * same resolution as if it hadn't been scaled. By downscaling, you + * reduce the size of the images. + * + * For jpeg and jp2k, downscaling reduces pdf size by the square of + * the scale factor. + * * The jpeg quality can be specified from 1 (very poor) to 100 + * (best available, but still lossy); use 0 for the default (75). + * * The jp2k quality can be specified from 27 (very poor) to 45 (nearly + * lossless; use 0 for the default (34).
