If you import a bitmap cast member with a color depth or color palette that is different from that of the Stage (the current movie), Director lets you select the images color depth and color palette. You can choose to import the bitmap at its original color depth or at the Stage color depth. (The Stage color depth is the same as the system color depth.) You can also choose to import the images color palette or remap the images colors to a palette in the movie.
In many cases, its easiest to change the images color depth to the depth of the movie and remap the image to the color palette that is used in the rest of the movie. For more information about controlling color in Director, see Color, Tempo, and Transitions.
If you change 16-, 24-, or 32-bit cast members to 8 or fewer bits, you must remap the cast members to an existing color palette.
Select bitmap image options for importing
Image specifies the color depth and palette of the image.
Stage specifies the color depth of the current Stage.
Import imports the image with its color palette. The palette appears as a new cast member immediately following the bitmap cast member.
Remap To replaces the images colors with the most similar solid colors in the palette you select from the menu.
Trim White Space removes any white pixels from the edges of the image. Deselect this option to preserve the white canvas around an image.
Dither blends the colors in the new palette in the Palette section to approximate the original colors in the graphic.
