Question

Your computer science teacher asks you to sample a black and white image that is 4" x 6". How would you sample the image to provide a good digital approximation using the pixelation widget? What sample size would you use? How would your decision affect the digital representation?

Answer 1

Answer:

The largest dimensions we can make of an image with the pixelation widget is 255*255.

When an image is resized, the number of pixels in the image may be reduced or increased, which causes the image to be resampled. Resampling changes the file size.

Explanation: This is all I could find. I hope its helps Sorry.

Answer 2

The sample size that would provide a good digital approx. will be  255 x 255

When resizing images using the pixelation widget, the pixels of the image will either reduce or increase and the reduction/increase in the pixels will have an effect ( blurry effect ) on the image when viewed by the user.  also

when an image is resized the size of original size is either larger or smaller than the resampled image.

Hence to provide a good digital approx. using the pixelation widget from an image 4" x 6" is by using a sample size of 255 x 255

Note : A picture showing the effect of pixelation is attached below
