FIGURE 17.8
The Select Bitmap Image File dialog box lets you preview images before opening them.

FIGURE 17.9
The Bitmap Parameters rollout offers several settings for controlling a bitmap map.

The Bitmap Parameters rollout includes three Filtering options: Pyramidal, Summed Area, and None. These
methods perform a pixel-averaging operation to anti-alias the image. The Summed Area option requires
more memory but produces better results.
You can also specify the output for a mono channel or for an RGB channel. For maps that use only the
monochrome information in the image (such as an opacity map), the Mono Channel as RGB Intensity or
Alpha option can be used. For maps that use color information (for example, a diffuse map), the RGB
Channel can be RGB (full color) or Alpha as Gray.
