Setting bitmap cast member properties

To view important information about cast members, change a cast member's name, choose alpha settings, or turn on highlighting and dithering, you use bitmap cast member properties.

To view or change bitmap cast member properties:

1 | Select a bitmap cast member, and click the Member tab of the Property Inspector using the Graphical view.
| The Member tab displays the following:
| Updateable fields to view or change the cast member's name, a Comments field to enter text that appears in the Comments column of the Cast List window, and an Unload field that lets you determine how to remove a cast member from memory.
| View-only fields that indicate when the cast member was created and modified, and the name of the person who modified the cast member.
2 | If the bitmap cast member is linked to an external file, the full pathname for the file appears in the Filename field. To choose a different file to link to the cast member, either type a new file name into the field, or click the Browse button and select the path to the new file name.
3 | Click the Bitmap tab using the Graphical view.
4 | To invert the current cast member when the user clicks it, select Highlight When Clicked.
| Use this option to create buttons. Even if Highlight When Clicked is selected, the cast member will not do anything unless it is controlled by a behavior or Lingo script.
5 | To make Director approximate an original color in the bitmap if there is a palette problem, select Dither. When a color is not available because of a palette conflict, Dither displays a pattern of pixels of similar colors. If this option is off, Director uses the color in the current palette closest to the original.
6 | If the imported bitmap has a white canvas that you want to remove, select Trim White Space. If you want to retain the white canvas, deselect Trim White Space.
7 | To make Director use the alpha channel (transparency) data in the cast member, choose Use Embedded Alpha.
| This option is on by default for all imported cast members with alpha channel data.
8 | To determine how a transparent area receives a mouse click, use the Alpha Click Threshold slider to specify a value.
| Any area with a greater degree of opacity than the specified threshold will be able to receive a mouse click.
9 | To assign a different palette to an 8-bit cast member while maintaining the cast member's original palette references, choose a new palette from the Palette pop-up menu.
