Scale Image
The Scale image
dialog is available via the Image -> Scale menu. Scale image is
used to actually resize the dementions of the image. There are three methods available
for resizing images. The first is by pixels; you can adjust the dementions
of the image down to the individual pixel. The second is percentage;
The image will be resized to the specified percentage of the original.
The third is to simply half or double the size of the image. The
Preserve aspect ratio option automatically adjusts the width or height of
the image to ensure the new images dementions are in the same proportion
as the original. Disabiling this option will allow the width and height
to be changed independently.
