neighborhood). The Bicubic method is more sophisticated and uses 16
neighboring pixels (from a 4 4 pixel neighborhood). This larger
neighborhood provides more information about how the color is
changing in that particular part of the image and therefore can
improve the colors in the made-up pixels.
When you use the Resize command to decrease the image dimensions,
the pixel colors are averaged together. Imagine that you want to
decrease an image from 100 100 pixels to 50 50 pixels. The result
contains 2,500 pixels, which is one-fourth of the pixels used to
represent the original image. The different resampling methods
determine how much weight is given to the original pixels when they
are averaged together.
Are there other ways to resize an image?
In addition to using the Resize command, you can also change the
image size by changing the canvas size, cropping the image, printing
at a different size, using the Copy Special command, or using the Save
for Office command.
Increasing the canvas size adds pixels at the edge of the image.
Decreasing the canvas size hides pixels at the edges of the image (full
layer information is kept). For more information, see “Resizing the
canvas” on page 283.
Cropping an image deletes the pixels outside the selected crop area.
For more information, see “Cropping images” on page 162.
You can resize an image that you add to the Print Layout workspace by
dragging its selection handles. Resizing the image in this way does not
change the image file, which is helpful if you want to print the image
at various sizes. For more information, see “To resize an image in print
layout” on page 773.
