Generating overlay resources

When generating overlay resources (Embed, Export, and Merge mode), you must specify the resolution and color range for the overlay resources. You can also specify different GOCA modes for generating vector graphics.

Resolution

The AFP driver setting Resolution specifies the resolution of the generated overlays. This setting also sets the resolution of all generated images and fixed raster fonts.

Color settings

The AFP driver setting Color specifies whether to generate black and white, gray scale, or color overlays. The option to select depends on the capabilities of the printer. The following options are available:

•	None – All colors are mapped to black and white.

•	Yes – All colors are mapped to a limited set of colors.

•	Extended – All colors are mapped to the RGB 0-255 color model.

•	Grayscale – All colors are mapped to 256 shades of gray.

GOCA settings

The AFP driver setting GOCA applies to vector graphics in the overlay, and also to vector graphics drawn directly in the PageOUT tool. Which option to select depends on the capabilities of the printer. The following options apply:

•	None – GOCA is not used to generate vector graphics. Only vertical and horizontal lines are presented in the output.

•	Yes – Algorithms with simple GOCA objects are used to generate vector graphics. Enables printing of free lines, polygons, ovals, and round corners.

•	Extended – The extended GOCA set is used to generate vector graphics without GOCA fillets. Enables printing of free lines, polygons, ovals, and round corners.

•	Full – The full GOCA set is used to generate vector graphics with GOCA fillets. Enables printing of free lines, polygons, ovals, and round corners.

•	Raster All – All vector graphic objects on pages or overlays are rasterized. Enables printing of free lines, polygons, ovals and round corners as raster images.

•	Raster Patterns – All vector graphic objects with patterns are rasterized. GOCA supports only a limited set of patterns. This option allows rasterizing of objects filled by unsupported patterns.
