Check Maintain aspect ratio then
enter values for Max Width and Max
Height to scale to maximum
intended dimensions while
preserving the image's original aspect
ratio.
With
Maintain aspect ratio
unchecked, enter values for absolute
Width and Height to make images of
a fixed size. As aspect ratio is not
maintained, images may be stretched
horizontally or vertically.
Change the units of measurement to
percent, then enter identical
percentage values to scale Width and
Height in proportion (maintain
aspect ratio); otherwise, different
values will stretch images
horizontally or vertically.
Enter a DPI value to alter the original
resolution of the images.
Pick a method from the drop-down
list. Use Nearest Pixel for hard-edge
images, Bilinear Interpolation when
shrinking photos, Bicubic
Interpolation when enlarging photos,
and Lanczos3 Window when best
quality results are expected. The list is
ordered according to processing
times (fastest to slowest).
