This tool allows you to adjust the Level-Window values of the image by using the mouse left button.
Click on the image and move your mouse upwards and downwards to decrease and increase the level value, or move your mouse left and right to decrease or increase the window value. The level-window tool allows you to modify the brightness and the contrast of the image without changing the actual pixel values, it alters only the way that the pixels are displayed on the screen.
The user can use the Level-Window Dialog Box command of the View menu that allows the user to insert precise values in the level-window fields.
The level-window tool does not work with palette images.
