Working with objects

You can increase your image-editing capabilities using objects, which are independent image elements that float above the background. Objects are transparent layers that stack on top of one another. The background forms the bottom layer, and when you create new objects, they are added to the top of the stack. For example, when you open a photo, it becomes the background. You can then add shapes, brush strokes, sprayed images, and other objects on top of the photo.

Objects are like layers that you can stack on top of one another. This image consists of the background and two photo objects.

In this section you’ll learn about

the background

editable areas

You can create objects from scratch by applying brush strokes or creating shapes, or you can add brush strokes and shapes to an existing object. For more information about applying brush strokes and creating shapes, see “Painting” on page 429.

You can also create an object using an entire image background. The background cannot be edited or moved in the stacking order unless it is converted to an object.

Another way you can create an object is to define an editable area on an image background or another object. When you create an object from an editable area, you can include only the visible elements in that area. If an object is obscured by other objects, and you cannot see it, then it will not be included in the editable area. For information about defining editable areas, see “Masking” on page 413.

You can create an object using part of an image background. Here, an editable area is defined and then the selection is copied and moved.

All objects in an image have the same resolution and color mode. As you add objects to a file, the file size and memory requirements increase. To decrease file size, you can flatten an image by combining objects. For more information on combining objects, see “Grouping and combining objects” on page 450.

To retain objects when you save an image, you must save the image in the native Corel PHOTO-PAINT (CPT) file format. For more information on saving images, see “Saving and closing” on page 471.
