Using the Crop command to change image size
You can adjust the overall size of an image using the Crop command.
When you enlarge an image, Canvas adds white pixels.
When you reduce an image, Canvas crops out pixels and
discards the image data.
1
Select a paint object (not in edit mode) and choose Image >
Area > Crop. A dialog box displays the current size, width, and
height.
2
Under New Size, enter the size you want the image to be. You
can use percent, pixel, inch, centimeter, point, or pica values.
3
To set the position of the resulting image, click a square in the
Placement grid. For example, to crop the image from the right side
and bottom, click the upper-left square in the Placement grid. To
expand the image on all sides, click the center square.
4
Click OK to resize the image. If you are reducing the image
area, Canvas warns you it will delete pixels; click OK to proceed.
Using the Trim command to remove borders
The Trim command lets you remove same-color pixels that are near
the edge of the image area. This feature is useful for removing
unwanted white space or other borders that are not part of the main
image. For example, you scan a photo that doesnt fill the entire scan-
ner area, and there is a white border around the photo. The Trim com-
mand identifies the edges of the image, determines which pixels
around the border match, and deletes the unwanted border.
Note: Canvas alerts you if the image cant be trimmed because a bor-
der cant be found.
To trim an image: Select one or more paint objects to trim, and
then choose Image > Area > Trim. Canvas removes the border.
Using the Crop tool to change image size
You can use the Crop tool to select a rectangular part of an image and
hide the rest. This is called a soft crop. When you edit a soft-
cropped image, the cropped area reappears while the image is in edit
mode. When you finish editing, Canvas re-crops the image. To
access soft crop edit mode, select the Crop tool and then press
Command (Mac) or right-click (Windows).
You can specify relative or
absolute measurements in the
Image Crop dialog box
