Detailed Description

Class for drawing 2D primitives using GL2PS.

This class takes care of drawing the 2D primitives for the vtkContext2D class. In general this class should not be used directly, but is used internally by the vtkGL2PSExporter.

virtual int vtkGL2PSContextDevice2D::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkOpenGLContextDevice2D.

virtual void vtkGL2PSContextDevice2D::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkOpenGLContextDevice2D.

static

virtual void vtkGL2PSContextDevice2D::DrawPoly	(	float *	f,
		int	n,
		unsigned char *	colors = `0`,
		int	nc_comps = `0`
	)

virtual

Draw a poly line using the points - fastest code path due to memory layout of the coordinates. The line will be colored by colors array which has nc_comps components. If colors is not set and the current Pen's alpha channel is zero, no OpenGL calls are emitted.

Reimplemented from vtkOpenGLContextDevice2D.

virtual void vtkGL2PSContextDevice2D::DrawPoints	(	float *	points,
		int	n,
		unsigned char *	colors = `0`,
		int	nc_comps = `0`
	)

virtual

Draw a series of points - fastest code path due to memory layout of the coordinates. The colors and nc_comps are optional - color array.

Reimplemented from vtkOpenGLContextDevice2D.

virtual void vtkGL2PSContextDevice2D::DrawPointSprites	(	vtkImageData *	sprite,
		float *	points,
		int	n,
		unsigned char *	colors = `0`,
		int	nc_comps = `0`
	)

virtual

Draw a series of point sprites, images centred at the points supplied. The supplied vtkImageData is the sprite to be drawn, only squares will be drawn and the size is set using SetPointSize.

Parameters

colors	is an optional array of colors.
nc_comps	is the number of components for the color.

Reimplemented from vtkOpenGLContextDevice2D.

virtual void vtkGL2PSContextDevice2D::DrawQuadStrip	(	float *	,

Draw a series of markers centered at the points supplied. The shape argument controls the marker shape, and can be one of - VTK_MARKER_CROSS - VTK_MARKER_PLUS - VTK_MARKER_SQUARE - VTK_MARKER_CIRCLE - VTK_MARKER_DIAMOND

Parameters

colors	is an optional array of colors.
nc_comps	is the number of components for the color.
