Changing size, color depth, and color palette for bitmaps
You can use Transform Bitmap to change the size, color depth, and palette of selected cast members. Any change you make to a cast member's color depth or palette affects the cast member itself--not only its appearance on the Stage. You can't undo changes to the color depth and palette. If you want to keep a cast member's original bitmap unchanged but temporarily apply a different palette, use the Member tab in the cast member's Property inspector. To change the size of only the sprite on the Stage, use the Sprite tab in the sprite's Property inspector.
You can also remap images to new palettes with an image-editing program such as Macromedia Fireworks.
The Transform Bitmap dialog box displays values for the current selection. If you select more than one cast member, a blank value indicates that cast members in the selection have different values. To maintain a cast member's original value, leave that value blank in the dialog box.
To use Transform Bitmap:
Select the bitmap cast members to change.
Select Modify > Transform Bitmap.
To change the size of the bitmap, do one of the following:
If multiple cast members are selected, you can resize all the cast members to the dimensions you enter.
Enter new measurements (in pixels) in the Width and Height text boxes.
Enter a scaling percentage in the Scale text box.
Select Maintain Proportions to keep the width and height of the selected cast member in proportion. If you change the width, the proportional height is automatically entered in the Height text box. If you use Transform Bitmap to change several cast members at once, be sure to deselect Maintain Proportions. If you don't, all cast members are resized to the values in the Width and Height text boxes.
To change the color depth, select an option from the Color Depth pop-up menu.
For more information about the color depth of bitmap cast members, see Controlling color.
To change the palette, select a palette from the Palette pop-up menu and select one of the following remapping options:
Remap Colors replaces the original colors in the graphic with the most similar solid colors in the new palette. This is the preferred option in most cases.
Dither blends the colors in the new palette to approximate the original colors in the graphic.
256 grays
Remapped to closest colors in black and white
Dithered in black and white
Click Transform to execute the changes.
The settings you select in the Transform Bitmap dialog box can't be undone.
