Member Function Documentation

static std::unique_ptr<CYIBitmap> CYIGPUExportUtilities::ReadPixels ( const CYIRenderTarget &  rTarget, const CYIViewport &  rViewport, bool  bReadFromBackbuffer = true  )

static

Read back image data from a framebuffer. The specified viewport region in the render target will be returned as a CYIBitmap pointer.

When rTarget is a screen render target, the bReadFromBackbuffer parameter can be used to determine which buffer to read pixels from. By default, pixels are read from the back buffer.

Warning

This is a very costly operation, use render target framebuffers! Use this only if you need a software buffer.

static std::unique_ptr<CYIBitmap> CYIGPUExportUtilities::ReadPixels ( const CYIRenderTarget &  rTarget )

static

Returns the entire render target as a software buffer.
