Detailed Description

A renderer to draw textures as two dimensional surfaces to the screen.

Member Function Documentation

prepareState()

virtual void OpenGL::SurfaceRenderer::prepareState ( )

pure virtual

Push the current OpenGL state, and set up the adequate state for calling the render method.

render()

virtual void OpenGL::SurfaceRenderer::render ( const TextureGL *  tex, const Math::Rect2d &  dest  )

pure virtual

Draw a 2D surface from the specified texture.

The destination rectangle must be specified in the following coordinates system: x: left [0.0, 1.0] right y: top [0.0, 1.0] bottom

restorePreviousState()

virtual void OpenGL::SurfaceRenderer::restorePreviousState ( )

pure virtual

Pop the OpenGL state to restore it as it was before calling the prepareState method.

setFlipY()

void OpenGL::SurfaceRenderer::setFlipY

(

bool

flipY

)

Invert the surface along the Y coordinate

Causes the image to be drawn upside down

enableAlphaBlending()

void OpenGL::SurfaceRenderer::enableAlphaBlending

(

bool

enable

)

Set the alpha blending with already drawn content
