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 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.

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.

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
colorsis an optional array of colors.
nc_compsis the number of components for the color.
virtual void vtkGL2PSContextDevice2D::DrawQuadStrip ( float *  ,
int   
)
virtual

Draw a quad using the specified number of points.

virtual void vtkGL2PSContextDevice2D::DrawPolygon ( float *  ,
int   
)
virtual

Draw a polygon using the specified number of points.

virtual void vtkGL2PSContextDevice2D::DrawEllipseWedge ( float  x,
float  y,
float  outRx,
float  outRy,
float  inRx,
float  inRy,
float  startAngle,
float  stopAngle 
)
virtual

Draw an elliptic wedge with center at x, y, outer radii outRx, outRy, inner radii inRx, inRy between angles startAngle and stopAngle (expressed in degrees).

Precondition
positive_outRx: outRx>=0
positive_outRy: outRy>=0
positive_inRx: inRx>=0
positive_inRy: inRy>=0
ordered_rx: inRx<=outRx
ordered_ry: inRy<=outRy
virtual void vtkGL2PSContextDevice2D::DrawEllipticArc ( float  x,
float  y,
float  rX,
float  rY,
float  startAngle,
float  stopAngle 
)
virtual

Draw an elliptic arc with center at x,y with radii rX and rY between angles startAngle and stopAngle (expressed in degrees).

Precondition
positive_rX: rX>=0
positive_rY: rY>=0
virtual void vtkGL2PSContextDevice2D::DrawMarkers ( int  shape,
bool  highlight,
float *  points,
int  n,
unsigned char *  colors = 0,
int  nc_comps = 0 
)
virtual

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
colorsis an optional array of colors.
nc_compsis the number of components for the color.
virtual void vtkGL2PSContextDevice2D::DrawQuad ( float *  points,
int  n 
)
virtual

Draws a rectangle

virtual void vtkGL2PSContextDevice2D::DrawString ( float *  point,
const vtkStdString &  string 
)
virtual

Draw some text to the screen!

virtual void vtkGL2PSContextDevice2D::DrawString ( float *  point,
const vtkUnicodeString &  string 
)
virtual

Draw some text to the screen.

virtual void vtkGL2PSContextDevice2D::DrawMathTextString ( float  point[2],
const vtkStdString &  string 
)
virtual

Draw text using MathText markup for mathematical equations. See http://matplotlib.sourceforge.net/users/mathtext.html for more information.

void vtkGL2PSContextDevice2D::ApplyPen ( vtkPen *  pen)

Apply the supplied pen which controls the outlines of shapes, as well as lines, points and related primitives. This makes a deep copy of the vtkPen object in the vtkContext2D, it does not hold a pointer to the supplied object.

virtual void vtkGL2PSContextDevice2D::SetPointSize ( float  size)
virtual

Set the point size for glyphs/sprites.

virtual void vtkGL2PSContextDevice2D::SetLineWidth ( float  width)
virtual

Set the line width for glyphs/sprites.

virtual void vtkGL2PSContextDevice2D::SetLineType ( int  type)
virtual

Set the line type type (using anonymous enum in vtkPen).
