Choose Edit > Preferences, then click the PCX symbol. The following preferences panel appears:

You can set the following preferences for export:

The resolution defines how many pixels are present per inch (dpi = dots per inch). The higher the resolution, the better the quality. This however, also rapidly increases the size of the file at the same time.

If you set this option, notice how the memory requirement displayed at the bottom of the window changes.

This option allows you to specify a border width for the PCX image. This enables you to isolate your illustration from the background. A 5 mm border means that a white border of 5 mm will be left around the actual image.

This field allows you to specify the dimensions of the PCX file. This is governed either by the size of the drawing sheet in Arbortext IsoDraw or the actual extent of the elements.

The image depth (bit depth) option essentially allows you to control how many different colors a PCX file can contain. A line-art illustration can only contain black or white pixels, a grayscale image can contain up to 256 different grayscales. Color images are limited to 256 colors (8 bits) or any of the settings up to and including 16.7 million colors.

The compression option allows you to markedly reduce the size of the PCX file without affecting the quality of the image. Not all programs are able to read compressed PCX files.
