The Info palette can provide some useful insight into bitmap images. In the upper left, you will see three letters (R, G, and B) for the red, green, and blue colour components. In the upper right, you will see four letters (C, M, Y, and K) for the cyan, magenta, yellow, and black colour components. (RGB and CMYK colour will be discussed in detail in lesson 4.4.)
In the lower left corner of the palette, you will see a plus (+) sign with the letters X and Y. This area will display the X and Y coordinates of the pixel you happen to be over as you move your mouse pointer around the image. In fact, as you move your mouse pointer over the image, the RGB and CMYK colour values and the coordinates will update.
In this image, the mouse pointer was placed over the eagle’s beak. In the info palette you can see the RGB colour components, the CMYK colour components, and the x and y coordinates in pixels of the precise spot that the mouse pointer hovers over. If the mouse pointer is moved to a different spot on the image, the data in the info palette will update to show the colour values and coordinates for the new position.
This info palette is a great way to explore and understand bitmap images because it shows you directly which colour values are mapped to which coordinates in the bitmap image.
