Chapter 5: Painting And Image Editing
If you select Pixels in the Width and Height menus, you cannot change these values, because
the number of pixels cannot change when Preserve Data is selected.
Width and Height: Specify a size for the paint object by entering values in these text
boxes. Select measurement units in the adjacent menus.
The width and height boxes show the size a paint object will become if you change the
resolution when Preserve Data is selected.
Preserve Proportions: This option links the Width and Height values so that changing one
value changes the other and maintains the original proportions of the paint object. Selecting
Preserve Data also selects this option. If you want to stretch a paint object in only one
direction, deselect Preserve Proportions.
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 dialog box appears in its compact
state.
3. Select pixels per inch or pixels per centimeter 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.
If you reduce resolution, paint objects become larger because the individual pixels are larger. If you
increase resolution, paint objects become smaller because the individual pixels are smaller.
1. Select one or more paint objects and choose Image | Area | Resolution.
2. In the Image Resolution dialog box, select Preserve Data.
3. Enter the desired resolution in the text box and click OK. Canvas changes the resolution of
the selected paint objects.
