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. |
