Return 1 if this class is the same type of (or a subclass of) the named class.

void vtkOpenGLGL2PSHelperImpl::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

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 vtkObject.

void vtkOpenGLGL2PSHelperImpl::ProcessTransformFeedback	(	vtkTransformFeedback *	tfc,
		vtkRenderer *	ren,
		vtkActor *	act
	)

overridevirtual

Parse the vertex information in tfc and inject primitives into GL2PS.

ren is used to obtain viewport information to complete the vertex transformation into pixel coordinates, and act/col are used to color the vertices when tfc does not contain color information.

Implements vtkOpenGLGL2PSHelper.

void vtkOpenGLGL2PSHelperImpl::ProcessTransformFeedback	(	vtkTransformFeedback *	tfc,
		vtkRenderer *	ren,
		unsigned char	col[4]
	)

overridevirtual

Parse the vertex information in tfc and inject primitives into GL2PS.

ren is used to obtain viewport information to complete the vertex transformation into pixel coordinates, and act/col are used to color the vertices when tfc does not contain color information.

Implements vtkOpenGLGL2PSHelper.

void vtkOpenGLGL2PSHelperImpl::ProcessTransformFeedback	(	vtkTransformFeedback *	tfc,
		vtkRenderer *	ren,
		float	col[4]
	)

overridevirtual

Parse the vertex information in tfc and inject primitives into GL2PS.

ren is used to obtain viewport information to complete the vertex transformation into pixel coordinates, and act/col are used to color the vertices when tfc does not contain color information.

Implements vtkOpenGLGL2PSHelper.

void vtkOpenGLGL2PSHelperImpl::DrawString	(	const std::string &	str,
		vtkTextProperty *	tprop,
		double	pos[3],
		double	backgroundDepth,
		vtkRenderer *	ren
	)

overridevirtual

Format the text in str according to tprop and instruct GL2PS to draw it at pixel coordinate pos.

Background depth is the z value for the background quad, and should be in NDC space. The drawing is always done in the overlay plane.

See also: TextAsPath

Implements vtkOpenGLGL2PSHelper.

void vtkOpenGLGL2PSHelperImpl::DrawPath	(	vtkPath *	path,
		double	rasterPos[3],
		double	windowPos[2],
		unsigned char	rgba[4],
		double	scale[2] = `nullptr`,
		double	rotateAngle = `0.0`,
		float	strokeWidth = `-1`,
		const char *	label = `nullptr`
	)

overridevirtual

Generate PS, EPS, or SVG markup from a vtkPath object, and then inject it into the output using the gl2psSpecial command.

The path is translated uniformly in the scene by windowPos. It is scaled by scale and rotated counter-clockwise by rotateAngle. The rasterPos is in world coordinates and determines clipping and depth. If scale is NULL, no scaling is done. If strokeWidth is positive, the path will be stroked with the indicated width. If zero or negative, the path will be filled (default). The label string is inserted into the GL2PS output at the beginning of the path specification as a comment on supported backends.

Implements vtkOpenGLGL2PSHelper.

void vtkOpenGLGL2PSHelperImpl::Draw3DPath	(	vtkPath *	path,
		vtkMatrix4x4 *	actorMatrix,
		double	rasterPos[3],
		unsigned char	actorColor[4],
		vtkRenderer *	ren,
		const char *	label = `nullptr`
	)

overridevirtual

Transform the path using the actor's matrix and current GL state, then draw it to GL2PS.

The label string is inserted into the GL2PS output at the beginning of the path specification as a comment on supported backends.

Implements vtkOpenGLGL2PSHelper.

void vtkOpenGLGL2PSHelperImpl::DrawImage	(	vtkImageData *	image,
		double	pos[3]
	)

overridevirtual

Draw the image at pos.

Image must be RGB or RGBA with float scalars.

Implements vtkOpenGLGL2PSHelper.
