About Virtual Pen Set (Edit Pen Set Dialog Box)

You can edit the DWF6 ePlot plotter configuration (PC3) file pen set and patterns.

You can modify virtual pen settings only if the Color Depth is set to 255 Virtual Pens.

When 255 Virtual Pens is selected, the settings in the plot style table associated with the drawing are ignored except the virtual pen number and plot style linetype. These settings are then saved to the PC3 file that you are editing. You can change pen lineweights (width), patterns, shapes, and effects by right-clicking a field in the dialog box to display a menu of common settings.

Note: When you have 255 Virtual Pens selected as your color depth, changing the resolution of the DWF file will change the width of your lines. Adjust the line width values in your pen set to compensate for this.

Unchecked pens (indicated by a red strike-through line) are ignored when you apply settings to the entire pen set.

Patterns

Provides 107 predefined pen patterns. Pen patterns can be used to alter the appearance of the geometry of a drawing. Many of the patterns provide a grayscale equivalent of a color. These patterns are commonly used for area fills in drawings for different percentages of black. There are also miscellaneous patterns such as boxes, tiles, slants, and diamonds that can be used to provide different effects.

Width

Sets the line width of the pen. Line widths are measured in pixels. These widths can also be represented in millimeters, centimeters, and inches. You set line widths in pixels (from 0 to 400). When you change the type of units, equivalent measurements in millimeters, centimeters, or inches for a 400 dpi printer are displayed.

Shape

Sets the end shape and join style of the pen.

Effect

Controls the appearance of the background pixels in a pattern. This effect works on monochrome, grayscale, and color plotters.

Transparent

Allows underlying objects to be visible through the pattern.

Opaque

Prevents underlying objects from appearing through the pattern.

All Pens

Applies scaling and width limitations to all pens in the pen set.

Note: The Scale Pen Widths settings are only visible when using viewing and plotting tools from Buzzsaw.

Controls

The effects of these settings are only visible when using viewing and plotting tools from Buzzsaw.

Allow Drawing to Manipulate

These settings are not supported for DWF files.

Map Pen Colors to a Shaded Half-Tone

Specifies that pen colors will be converted to the equivalent shades of gray.

Use Alternate Fill Instead of Winding Fill for Polygons

Specifies that an alternate fill will be used for polygons instead of a winding fill.

Use only if the fill pattern in a polygon does not appear to plot correctly for a vector file. The modes differ only in cases where a complex, overlapping polygon must be filled (for example, a five-sided polygon that forms a five-pointed star with a pentagon in the center). In such cases, alternate mode fills every other enclosed region within the polygon (such as the points of the star). Winding mode fills all regions (such as the points and the pentagon).

Use Error Diffusion for DWF Rasters

Specifies that error diffusion will be used for DWF raster images.

To represent shades of gray in raster data, halftone diffusion is used by default. You may want to use error diffusion instead to improve the appearance of your image.
