Windows Metafile (WMF) is a graphics file format intended to be portable between applications and may contain both vector graphics and bitmap components.
Enhanced Metafile (EMF), a newer version with additional commands is a 32-bit format that can contain both vector information and bitmap information.
This format is an improvement over the Windows Metafile Format and contains extended features, such as the following:
Exporting a WMF/EMF file brings up a dialog similar to the Print dialog.
Set the print dimensions of WMF/EMF images. The images are saved with a resolution of 300 DPI (Dot Per Inch).
The print width of the image.
The print height of the image.
Defines the printing method.
Prints lines, curves, and fill areas.
By default, Rhino prints everything it can using vectors.
Prints a bitmap image.
Defines how color is printed.
Uses the layer or property Print Color setting to print point objects, curves, annotations, and wireframes, etc. Mesh faces and surfaces are printed with display colors.
Print objects with the same wireframe color that displays in viewports.
Converts colors to gray scale.
List of viewport names and layout pages.
When a layout page is selected, the printer paper size changes to use the layout page size.
Prints the select viewport or layout page.
Zoom the current viewport to contain all objects in the model.
Prints a selected window area.
Select a new print area. The window grips can be manipulated after the window is drawn.
Move the selected print area.
Prints multiple layout pages. Enter a comma-separated list of page numbers or page ranges. For example: 1,2,4-8.
Multiple page prints are sent out as a single print job so printing to PDF should result in a single PDF file with multiple pages.
Prints all layout pages.
When printing multiple layouts to image file, multiple image files will be created all with an ascending index suffix appended to the file name.
Displays current display magnification as percentage. Select scale from the list or set the scale in paper units=model units.
Sets the units used on the printed page and the equivalent units used in the model.
Sets or expands the non-print areas around the page.
Each of the options controls the position, margins, width, and height options.
Sets margins for all four sides.
Sets the top and left margins and a width and height for the print area.
Sets the top and right margins and a width and height for the print area.
Sets the bottom and left margins and a width and height for the print area.
Sets the bottom and right margins and a width and height for the print area.
Centers the print area and sets a width and height.
Sets the margins and position to the same aspect ratio as the selected viewport/layout.
Sets the margins to the printer maximums.
Centers the image in the print area.
If the Centered box is not checked, choose from offset options.
Offsets the image in the print area from the lower left.
Offsets the image in the print area from the upper left.
Offsets the image in the print area from the lower right.
Offsets the image in the print area from the upper right.
Specifies the offset amount in the x and y directions and sets the offset units.
Printed line type pattern matches values in linetype definition file.
Printed linetype pattern matches the current display properties
Multiplier to globally change printed line widths.
Ranges from Hairline through normal drafting widths (in millimeters) through No Print.
Size for point objects on the printed page.
Size for arrowheads on the printed page.
Size for the text dot font on the printed page.
Optional items to include on the printed page.
Prints the viewport background color.
Prints the viewport background bitmap.
Prints the viewport wallpaper.
