If a picture contains a graphic of the RGB value of 0xF7f7f7, the graphics area is severely biased in the image and fax viewer. Put it in the drawing program to see it (you can see it without comparison, the contrast is just a license). There is a simple example XP's resource manager to select the viewing method as the details. At this time, the base color of the sequence is 0xf7f7f7, and the screenshot can verify that I said. At first I doubted that my monitor was not normal or my eyes were not normal. Later, open the drawing program and the picture viewer, it is believed to be the bug of XP.
