Novell LINUX ENTERPRISE DESKTOP 10 SP1 - KDE 14-05-2007, Руководство пользователя, Страница: 246 / 354

A small window opens with information about the starting point and the size of the se-
lected area. Adjust these values by clicking and dragging a corner of the crop box or
by adjusting the values in the window. From Selection adjusts the crop to fit the current
selection (selections are explained in
Section 18.5.2, “Selecting Parts of Images”
(page 235)). Auto Shrink makes the crop smaller based on color changes in the image.
Press Cancel to abort the crop. Press Crop to crop the image. The results of Resize are
identical to those of Change Canvas Size, described in
Section “Changing the Canvas
Size” (page 234).
Scaling an Image
Select Image > Scale Image to change the overall size of an image. Select the new size
by entering it in Width or Height. To change the proportions of the image when scaling
(this distorts the image), click the chain icon to the right of the fields to break the link
between them. When those fields are linked, all values are changed proportionately
when the value in one of the fields is changed. Adjust the resolution with X resolution
and Y resolution.
Interpolation is an expert option that controls the scale method. When finished adjusting
the size, press Scale to scale the image. Reset restores the original values. Cancel aborts
the procedure.
Changing the Canvas Size
Changing the canvas size is like putting a mat around an image. Even if the mat is
smaller, the rest of the image is there, but you can only see part of it. If the mat is larger,
you see the original image with extra space around it. To do this, select Image > Canvas
Size.
In the dialog that opens, enter the new size. By default, the width and height maintain
the same proportions as the current image. To change this, click the chain icon.
After adjusting the size, determine how the existing image should be positioned in
comparison to the new size. Use the offset values or drag the box inside the frame at
the bottom. When satisfied with the changes, click Resize to change the canvas size.
Click Reset to restore the original values or Cancel to cancel the canvas resize.
