From http://itextdocs.lowagie.com/tutorial/objects/images/index.php:
Note that the resolution of an image that is added without scaling will be 72dpi by default. If an image is placed with a scaling of 50% the the resolution will be 144. With lower scalings the resolution will increase because the pixels are the same but the size will be smaller. To put a picture with 300dpi use a scaling of 72/300=24%. For instance: if you have a 5X5 inch image that you scan at 300 dpi, the resultant image is 1500X1500 pixels (5X300 = 1500). When you place this image in the pdf with a scaling of 24% (72/300 = 0.24), the image in the pdf will be 5X5 inch with 1500X1500 pixel at 300 dpi. The image will always be 1500X1500 pixel whatever the size.
