A greyscale image is a graphic image which is rendered completely in black and white and shades of grey, no other colors.
gray scale so that we can process our image
Gray scale slicing gives partially gray scale image that is nor pure white neither pure black.
It is factor to scaling down the image.
There is no relation between the image size (pixel count) and the number of color or gray levels supported. Therefore there is no answer to this question.If your question is how many levels of gray does a grayscale image allow, please post it like this.
A gray level image is an image that contains only shades of gray (if it is a RGB image, than all its pixels satisfy R=G=B)
Dorian Gray Actually, in the case of Dorian Gray it's not a mirror image but a portrait.
With a scale factor of 1, the image is exactly the same size as the original object.
Gray Scale: Using black and white and shades of gray, the scanner is able to translate the image into gray scales. Why would you use a gray scale scanner? If you plan to print on a black and white printer, it is most cost effective since color ink is so expensive. Text is best done on a grayscale scanner. Color: A color scanner scans images in red, blue, and green shades. This scanner is more expensive in terms of final print output . A color scanner usually costs more than a gray scale scanner. If you plan on doing presentation work, work with color photographs, or any sort of task that requires a color output, then use a color scanner. With this scanner you can also choose options of scanning such as line art (scanning the image only in black or white), grayscale (black, white, and shades of gray, or color (shades of red, blue, and green).

You need information about a pre-image AND and image to work out a scale factor.
Grey, of course.
on your printer settings before you print, you should set your options to what you want instead of gray scale
