Changing resolution
You can change the resolution of paint objects in two ways:
If you do not want to change an objects size, you can resam-
ple the image. Resampling merges or divides pixels.
If you want to preserve all the data in an image, you can
change the objects resolution and allow its size to change.
Decreasing resolution (down sampling) decreases file size by dis-
carding data. This can result in lost detail. However, its common to
reduce resolution in some situations. For web pages and other appli-
cations where images are displayed on a monitor, 72 ppi is the stan-
dard resolution.
Rarely, an image is resampled to increase resolution. This should be
avoided because additional pixels are created by estimating their
color values, which does not improve an image.
The Resolution dialog box has compact and expanded states. In its
compact state, you can easily change the resolution of multiple paint
objects without needing to specify additional options.
Note: When more than one paint object is selected (unless the objects
are the same size and resolution), the button that displays additional
options in the Resolution dialog box is not available.
To change resolution by resampling
This procedure reduces resolution of paint objects for use on a web
page or in a presentation.
1
Select one or more paint objects. These objects can vary in size
and resolution.
2
Choose Image > Area > Resolution. The Image Resolution dia-
log box appears in its compact state.
3
To specify resolution, select pixels per inch or pixels per centi-
meter and enter the resolution value in the text box.
4
Click OK. Canvas changes the resolution of the selected objects,
which remain the same size.
To change resolution without resampling
Use this procedure to change the resolution of paint objects without
resampling. This changes the size of objects while preserving the
image data.
