Resizing Images
To change an image's size select Image | Resize... on the
Menu Bar.
There are four different methods of changing the height and width of an
image.
- Bicubic
- Bilinear
- Pixel Resize
- Smart Size
The Bicubic Method is for enlarging images. Through a
process called
interpolation, the Bicubic Method minimizes the raggedness normally
associated with enlarging an image by estimating how the 'missing'
pixels should appear, then filling them in with the appropriate
color to smooth out the rough spots. Use the Bicubic Method to
enlarge photographic type images and the Bilinear Method to
shrink them.
The same image enlarged using the Pixel Resize method shows
rough and jagged edges. This is due to the fact that this method
duplicates or removes pixels to achieve the desired results. Pixel
Resize
should be used with hard-edge images such as line drawings.
The Smart Size Method chooses the best algorithm based on
the current image characteristics.
