Detailed Description

vtkContextDevice2D implementation for use with vtkPDFExporter.

Quirks:

Libharu does not support RGBA images. If an alpha channel is present in any drawn images, it will be blended into an opaque background filled with the active Brush color to produce a flat RGB image.

void vtkPDFContextDevice2D::SetLineWidth ( float width )

overridevirtual

Set the line width.

Implements vtkContextDevice2D.

◆ DrawPolyData()

void vtkPDFContextDevice2D::DrawPolyData	(	float	p[2],
		float	scale,
		vtkPolyData *	polyData,
		vtkUnsignedCharArray *	colors,
		int	scalarMode
	)

overridevirtual

Draw the supplied PolyData at the given x, y (p[0], p[1]) (bottom corner), scaled by scale (1.0 would match the actual dataset).

Only lines and polys are rendered. Only the x/y coordinates of the polydata are used.

Parameters

p	Offset to apply to polydata.
scale	Isotropic scale for polydata. Applied after offset.
polyData	Draw lines and polys from this dataset.
colors	RGBA for points or cells, depending on value of scalarMode. Must not be NULL.
scalarMode	Must be either VTK_SCALAR_MODE_USE_POINT_DATA or VTK_SCALAR_MODE_USE_CELL_DATA.

The base implementation breaks the polydata apart and renders each polygon individually using the device API. Subclasses should override this method with a batch-drawing implementation if performance is a concern.

Reimplemented from vtkContextDevice2D.
