Detailed Description

Specialisation of RenderTarget interface that should be used as the base class for RenderTargets that are implemented using textures.

Member Function Documentation

virtual void CEGUI::TextureTarget::declareRenderSize ( const Sizef sz)
pure virtual

Used to declare to the TextureTarget the largest size, in pixels, of the next set of incoming rendering operations.

Note
The main purpose of this is to allow for the implemenatation to resize the underlying texture so that it can hold the imagery that will be drawn.
Parameters
szSize object describing the largest area that will be rendererd in the next batch of rendering operations.
Exceptions
InvalidRequestExceptionMay be thrown if the TextureTarget would not be able to handle the operations rendering content of the given size.

Implemented in CEGUI::Direct3D9TextureTarget, CEGUI::Direct3D10TextureTarget, CEGUI::Direct3D11TextureTarget, CEGUI::IrrlichtTextureTarget, CEGUI::OpenGLWGLPBTextureTarget, CEGUI::OpenGLESFBOTextureTarget, CEGUI::OpenGL3FBOTextureTarget, CEGUI::OpenGLFBOTextureTarget, CEGUI::NullTextureTarget, CEGUI::OgreTextureTarget, CEGUI::OpenGLGLXPBTextureTarget, and CEGUI::OpenGLApplePBTextureTarget.

virtual Texture& CEGUI::TextureTarget::getTexture ( ) const
pure virtual
virtual bool CEGUI::TextureTarget::isRenderingInverted ( ) const
pure virtual

Return whether rendering done on the target texture is inverted in relation to regular textures.

This is intended to be used when generating geometry for rendering the
TextureTarget onto another surface.
Returns
  • true if the texture content should be considered as inverted vertically in comparison with other regular textures.
  • false if the texture content has the same orientation as regular textures.

Implemented in CEGUI::Direct3D9TextureTarget, CEGUI::Direct3D10TextureTarget, CEGUI::Direct3D11TextureTarget, CEGUI::IrrlichtTextureTarget, CEGUI::OpenGLESFBOTextureTarget, CEGUI::OpenGLTextureTarget, CEGUI::NullTextureTarget, and CEGUI::OgreTextureTarget.
