Converting an image from Bitmap mode to Grayscale modeYou can convert a Bitmap-mode image to Grayscale mode so you can edit it. Keep in mind that a Bitmap-mode image edited in Grayscale mode may not look the same when converted back to Bitmap mode. For example, a pixel that is black in Bitmap mode and then edited to a shade of gray in Grayscale mode may have a gray value that is light enough that it will become white when converted back to Bitmap mode. To convert a Bitmap-mode image to grayscale:
The size ratio is the factor for scaling down the image. For example, to reduce a grayscale image by 50%, enter 2 for the size ratio. If you enter a number greater than 1, the program averages multiple pixels in the Bitmap-mode image to produce a single pixel in the grayscale image. This process lets you generate multiple shades of gray from an image scanned on a 1-bit scanner. |
