Used to select the version of PDF that is created.

Set the format colour are stored in the resulting PDF files. The options are RGB and CMYK.

RGB values produce slightly smaller output files and the resulting PDF files will look closer to the original DGN file colour when displayed on screen using Acrobat Reader. This option would be recommended for users intending to publish PDF files online or send the output to composite colour printers (lasers, inkjets).

CMYK output is highly recommended if the resulting PDF file is intended to be for producing colour separations. This allows additional control over the final colour output including specification of spot colours using the Bentley Advanced Map Finishing Colour Table.

The precision property controls the number of digits after the decimal point used in coordinates written to the PDF file. Higher precision improves print quality, especially for TrueType text, at the expense of larger PDF file sizes.

The default precision, Standard, is designed to produce the smallest PDF file size with good text quality at printer resolution. PDF coordinates are rounded to 1/10th of a point. At high zoom levels in a PDF viewer, text may appear slightly deformed.

If the precision is set to Improved, text coordinates are rounded to 1/100th of a point while other coordinates are rounded to 1/10th of a point. This setting is designed to balance text quality at high zoom levels with PDF file size. PDF file sizes may be between 10-25% larger than when using Standard precision.

If the precision is set to High, all coordinates are rounded to 1/100th of a point. PDF file sizes may be between 20-50% larger than when using Standard precision.

If the precision is set to Maximum, no coordinates are rounded. PDF file sizes may be between 30-80% larger than when using Standard precision.

Enables output of layer information to the PDF to allow users to control the display of layers.

If enabled and the user is allowed to print, the layers will print as created and not as displayed in the PDF viewer.

Selected the way the level name is displayed in the Layer table:

• Level Display Name : Level display names (formatted by the MS_LEVEL_DISPLAY_FORMAT configuration variable) are used. You can use the level name, number, and description in any order.

• Level Name : Unformatted level names are used.

• Level Description : Level descriptions are used.
