The Visibility tab contains four separate group sections:
- Visibility
- Opacity mask
- Background removal
- Pre-rendering (only visible if Pre-rendering is enabled under page Setup)
Visibility
In the visibility group you can set the opacity of the image on the Page design. This can be used to create ghosting images. For example, see the differences in the images shown below:
| No Opacity | Opacity 50% |
|---|---|
 |  |
Besides setting the opacity for the image, you can also select the visibility of the image as well the printability. Each drop down menu offers three selections:
- Visible
- Hidden
- Collapsed
Opacity Mask
With the Opacity mask you can do some great and advanced stuff. For example, we have created an opacity mask using the gradient tool and the background color orange.
Now take a look at the photo images below. On the left you have the original and on the right the photo with the opacity mask.
No Opacity | Using Opacity Mask |
|---|---|
|  |
But you can also load images or use solid colors.
Background Removal
Use the sliders to define the correct removal. You can also enter the values directly into the text boxes right from each color slider. For example, we removed the background based on the slider configuration below.
Now take a look at the photo images below. On the left you have the original and on the right the photo with the background removed.
| No Removal | Background Removed |
|---|---|
|
|
It is important to realize that the result of the background removal depends on the quality of the image and the used background. Always try to use real blue or green backgrounds when taking photos as this offers the best removal result.
Pre-rendering
When you have enabled pre-rendering of objects into the background image, you will see an aditional check-box to flag each object to be pre-rendered.
By default this is enabled for images and shapes, but not for text or Barcodes.
Aall objects that have been flagged for pre-rendering, together with the background image or brush of the layout page, will be rendered to a bitmap image and sent as such to the printer.
Pre-rendered objects will always show behind any other objects in the printed result, even if that is not the case on the preview.
