Create a transparent sprite
The transparency of a sprite is especially useful when you move or copy an object. For this operation, pure colors are normally used.
1. Right-click on the sprite and choose Properties.
2. Click on the Transparency tab.
3. If the box "Using a transparent color" is checked, the specified transparent color and tolerance will be used to create a transparent area in the sprite. If the box is not checked, the sprite is opaque.
4. In the Transparent color Group:
In the Red area, enter the red component of the 'transparent' color. Values from 0 to 255 can be specified. The "Using a transparent color" box must be checked to access this value.
In the Green area, enter the green component of the 'transparent' color. Values from 0 to 255 can be specified. The "Using a transparent color" box must be checked to access this value.
In the Blue area, enter the blue component of the 'transparent' color. Values from 0 to 255 can be specified. The "Using a transparent color" box must be checked to access this value.
In the Tolerance area, specify the tolerance of the 'transparent' color. The color tolerance setting determines how close the color of a pixel must be considered as the 'transparent' color. Values from 0 to 100 percent can be specified (20% is generally a good value). The "Using a transparent color" box must be checked to access this value.
In the Overall opacity area, specify the global object opacity.
Create Transparent sprite using directly click in the sprite preview
1. Right-click on the sprite and choose Properties.
2. Click on the Transparency tab.
3. Click in the sprite preview. This area permits you to specify a transparent color by clicking directly on the picture preview. The "Using a transparent color" box must be checked if you want to click in this area.
Create Transparent Sprite using drag and drop
1. Select a sprite in the librarian.
2. Drag and drop to the Screensaver Document window.
When you add sprites by using drag and drop from the librarian, the application automatically sets the sprite background to transparent. The upper left pixel color is used to determine the transparent color except the JPEG, JPG files (the background is opaque).
