Remarks

This class is an abstract class for all vectorize actions. The supported subclasses are SoVectorizeCGMAction, SoVectorizeGDIAction (Win32 only), SoVectorizeHPGLAction, and SoVectorizePSAction. As with SoWriteAction, these subclasses contain an SoVectorOutput instance (or derived) which writes by default to standard output. Methods on SoVectorOutput can be called to specify what file to write to.

Default values:

Orientation: PORTRAIT
Start position: X=10.0 mm and Y=10.0 mm
Dimensions: Width=190.0 mm and Height=277.0 mm
Border width: 2.0 mm
Border color: (1.,1.,1.)
Background: no background
Nominal width: 0.35 mm
Pixel image size: 0.35mm
Color Translation method: REVERSE_ONLY_BLACK_AND_WHITE
Number of pens: 0
Color priority: true
Line End Style: BUTT_END
Line Join Style: NO_JOIN
Miter limit: 1.5 (Miter Length / Line Width)
HLHSR mode: NO_HLHSR
Lighting enabled: false
Polygon/Line/Marker offset: 0
Shade model: FLAT
HLHSR raster quality: 0.5

Line end styles description:

Force black and white rendering: It is possible to force black and white rendering by setting the environment variable OIV_HC_BLACK_AND_WHITE (see SoPreferences). In this mode all non-white colors are set to full black. This is useful because selecting "black & white" in the printer setup dialog normally produces gray scale rendering and some colors may be difficult to see. This option is applied after color translation (e.g. REVERSE_ONLY_BLACK_AND_WHITE). The variable must be set before creating an instance of the class.

Performance: The HLHSR modes NO_HLHSR and HLHSR_SIMPLE_PAINTER are generally quite fast and should be used whenever possible (when the resulting image quality is acceptable or when a quick preview is desired). The other HLHSR modes involve computations that are very CPU intensive. In other words, the time required to produce an image depends almost entirely on the machine's processor speed. HLHSR_PAINTER_SURFACE_REMOVAL has a very small dependency on the graphics board (because it does one offscreen render) whereas HLHSR_RASTER performance is completely linked to the graphics board performance. The other modes are not affected by the graphics board performance. One implication of the CPU dependency is that the release libraries will generally be much faster than the debug libraries (because of compiler optimizations). Benchmarking should always be done using the release libraries.

Performance is directly related to the number of primitives (individual faces and line segments, not the number of nodes in the scene graph) and the number of intersecting or difficult-to-sort primitives. Performance decreases rapidly (worse than linear) for large numbers of primitives. Therefore algorithms that can reduce the number of primitives may be needed for large scenes (see, for example, SoSimplifyAction).

In some cases setting a small polygon offset can improve performance by reducing interference between faces and lines (used only with the Painter's algorithm HLHSR modes).

HIDDEN_LINES_REMOVAL mode is very slow and should not be used unless very precise output is required.

Generally HLHSR_RASTER mode gives the best combination of performance and image quality.

Limitations

Modeling clipping (SoClipPlane) is ignored.
Textures are ignored (polygons are drawn as if no texture is applied).
Transparency is ignored.
SoAnnotation nodes are handled like SoSeparator nodes.
Smooth shading is only supported with PostScript Level 3.
SoText2 (and SoAnnoText3 using an xxx_PRINT_RASTER option) will be rendered using native fonts, so the requested font name must be available on the rendering device.
VolumeViz representations are not supported (because texturing is not possible).
FXViz representations are not supported.
