48 ULEAD PHOTOIMPACT USER GUIDE
Changing dimensions by resampling
When you open images, their size on screen is determined by your screen
resolution and the number of pixels the images contain. Image Size allows you to
adjust the number of pixels in an image. As resampling changes the image's
number of pixels, the file size is modified correspondingly.
Use Resample when:
• Changing the size of an image as it is displayed on screen.
• Making the file size of an image smaller so that it takes less time to import it
into another application and print it from there.
• Resizing or distorting an image.
To resample an image:
1. Select Adjust: Resize.
2. In Apply to, select which objects are being resampled. If the image contains
multiple objects, you can choose whether to resample only selected objects, or
all objects including the base image.
3. Specify the target dimensions for resampling in New image or Document
size. You can also change Resolution (usually for printing), and use Preview
to check the effect of the new settings with reference to size and target output.
4. Select Resample and method of resampling.
5. Click OK.
Tip: PhotoImpact uses a resample method (interpolation algorithm) to add new
pixels based on the existing pixels (color squares) in an image. Bicubic makes
a fine and softer image using the smallest file size. Bilinear makes a soft
image, while Nearest Neighbor makes a sharp image with the largest file size.
Using the clipboard
The clipboard acts as a temporary storage for different types of data, such as
images, text, or sound. However, it only holds data one at a time. Whenever new
information is placed in the clipboard, the previous data is automatically
overwritten, regardless of where the new data came from.
Performing cut and copy operations
The most common methods for placing data onto the clipboard are by clicking Cut
[Ctrl+X] and Copy [Ctrl+C] on the Standard Toolbar, or by selecting their
respective commands from the Edit menu.
