Getting Information about the Pixels in an Image

Often, you need to get information about the pixels in an image, such as their location and value. The Image Tool provides several ways to get this information, including:

• Pixel Information tool -- Displays the location and value of the pixel under the cursor in the lower left corner of the Image Tool window. See Determining the Value of Individual Pixels for more information.
• Display Range tool -- Displays the display range of the image in the lower right corner of the Image Tool window. See Getting the Display Range of an Image for more information.
• Pixel Region tool -- Displays an extreme close-up view of the pixels in a specific region of an image. See Viewing Pixel Values with the Pixel Region Tool for more information.
