Detailed Description

Class for drawing 2D primitives using OpenGL 2.

This class takes care of drawing the 2D primitives for the vtkContext2D class. In general this class should not be used directly, but called by vtkContext2D which takes care of many of the higher level details.

It assumes that OpenGL 2 is available, which is taken care of by the vtkContextActor class. If OpenGL 2 is not available, but OpenGL rendering is required the vtkOpenGLContextDevice2D class should be used (employs GL 1.1).

virtual int vtkOpenGL2ContextDevice2D::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.

const

virtual void vtkOpenGL2ContextDevice2D::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 vtkOpenGL2ContextDevice2D* vtkOpenGL2ContextDevice2D::New ( )

static

Creates a 2D Painter object.

static bool vtkOpenGL2ContextDevice2D::IsSupported ( vtkViewport *  viewport )

static

Return true if the current rendering context supports this device.

virtual void vtkOpenGL2ContextDevice2D::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. Points are colored by colors array which has nc_comps components

Reimplemented from vtkOpenGLContextDevice2D.

virtual void vtkOpenGL2ContextDevice2D::DrawImage ( float  p[2], float  scale, vtkImageData *  image  )

virtual

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

Reimplemented from vtkOpenGLContextDevice2D.

void vtkOpenGL2ContextDevice2D::DrawImage ( const vtkRectf &  pos, vtkImageData *  image  )

virtual

Draw the supplied image at the given position. The origin, width, and height are specified by the supplied vtkRectf variable pos. The image will be drawn scaled to that size.

Implements vtkContextDevice2D.

virtual void vtkOpenGL2ContextDevice2D::ReleaseGraphicsResources ( vtkWindow *  window )

virtual

Release any graphics resources that are being consumed by this device. The parameter window could be used to determine which graphic resources to release.

Reimplemented from vtkOpenGLContextDevice2D.

virtual bool vtkOpenGL2ContextDevice2D::LoadExtensions ( vtkOpenGLExtensionManager *  m )

protectedvirtual

Load the OpenGL extensions we need.

Reimplemented from vtkOpenGLContextDevice2D.
