enum MISRCalculator::MISRCalculatorException
This enum describes the exception values in the MISRCalculator class.
| Constant | Value | Description |

Member Function Documentation
MISRCalculator::MISRCalculator(SafeRenderer::AbstractFrameBuffer &frameBuffer, const SafeRenderer::QSafeSize &sizeArg)
Constructs a MISR calculator object with a frameBuffer. frameBuffer is the implementation of the AbstractFrameBuffer for the OpenWFD API. sizeArg holds the width and height for the framebuffer. Throws SafeRenderer::MISRCalculator::UnsupportedSurfaceFormat if the framebuffer surface format is not ARGB32.
[virtual] MISRCalculator::~MISRCalculator()
Destructor.
void MISRCalculator::getCRC(SafeRenderer::VerifyRegion ®ion)
Calculates the MISR value for region.
Throws SafeRenderer::MISRCalculator::RegionOutOfBounds if the region is out of bounds.
