Detailed Description

Class used to write vector formatted files in PostScript format.

This class is used for writing vector formatted files in Adobe PostScript format. It provides some convenience functions for handling files. An instance of SoPSVectorOutput is contained in an SoVectorizePSAction; this is typically the only instance needed.

Constructor & Destructor Documentation

SoPSVectorOutput()

SoPSVectorOutput::SoPSVectorOutput

(

)

Constructor.

The default constructor writes to stdout.

~SoPSVectorOutput()

virtual SoPSVectorOutput::~SoPSVectorOutput ( )

virtual

Destructor.

The destructor closes any files opened by the SoPSVectorOutput.

Member Function Documentation

getColored()

SbBool SoPSVectorOutput::getColored ( ) const

inline

Gets the colored output flag.

Definition at line 64 of file SoVectorizePSAction.h.

getLevel()

unsigned int SoPSVectorOutput::getLevel ( ) const

inline

Returns the PostScript language level.

Definition at line 81 of file SoVectorizePSAction.h.

getNumericAccuracy()

float SoPSVectorOutput::getNumericAccuracy ( ) const

inline

Returns the factor used to compute the accuracy of all real numeric values.

See setNumericAccuracyFactor() for details.

Definition at line 110 of file SoVectorizePSAction.h.

setColored()

void SoPSVectorOutput::setColored ( SbBool  flag = TRUE )

inline

Sets the colored output flag.

By default, the flag is set to TRUE.

Definition at line 58 of file SoVectorizePSAction.h.

setLevel()

void SoPSVectorOutput::setLevel

(

unsigned int

level

)

Sets the PostScript language level.

Supported levels range from 1 to 3. The default level is 2. With levels 1 and 2, only flat shading is supported whereas with level 3 and higher, smooth shading is supported. See also SoVectorizeAction::setShadeModel().

setNumericAccuracyFactor()

void SoPSVectorOutput::setNumericAccuracyFactor ( float  factor )

inline

Sets the factor used to compute the accuracy of all real numeric values.

The default value is 0.1.

In order to reduce the PostScript file size, all real numeric values are stored as integer values. The formula used to compute an integer value from a real numeric value is the following:

Integer part of (realValue / (0.24 * NumericAccuracyFactor)) + 0.5

All integer values are globally scaled by 0.24 * NumericAccuracyFactor. Thus this factor allows you to specify higher or lower accuracy, which will have a significant influence on the size of the resulting file. The range of this factor is usually 0.01 <= NumericAccuracyFactor <= 1.0
