File Type Options - SUN Raster

The File Type Options dialog is entered when you press Options in the Image Conversion dialog or the Send Image dialog. The dialog allows you to specify convert options for the currently selected image file format.

The available options depend on the file format. Here are shown the options for the SUN raster file format.

Color Mode

Best Fit: Let EasyCopy determine the best color mode. This is the default. EasyCopy will choose the optimal color mode for the given image taking other current settings into account.
RGB: RGB means a 24-bit RGB image ("true color").
Gray Scale: If possible a gray scale image using 8 bits per pixel is written, or a colormap defining 256 shades of gray is used.
Bilevel: Bilevel means a bilevel, black-and-white image.
Color Map: A color mapped image with 256 different colors (8 bits per pixel).

Colors
This field is only visible when Color Mode is Color Map. Enter the number of desired colors (2-256) in this field.

Error Diffusion
Enable this option if you want color differences distributed to the neighboring pixels. Normally, this results in a substantially better color rendering, although at the expense of image details; the sharpness becomes slightly degraded. Refer also to the topic Image Shading.

Colormap
This is the color map to be used, if the selected Color Mode results in the creation of a color map of exactly 256 colors.

Optimized: A color map that gives the best representation of the input image. If the input image also is color mapped, the original color map is used. Otherwise, a color map optimized for the current image is calculated.
Standard: A fixed, predefined color map. This option is useful if several images are to appear side-by-side on a device that can only display 256 colors.
