Member Function Documentation

NXPCalculator::NXPCalculator(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::NXPCalculator::UnsupportedSurfaceFormat if the framebuffer surface format is not ARGB32.

[virtual] NXPCalculator::~NXPCalculator()


void NXPCalculator::getCRC(SafeRenderer::VerifyRegion &region)

Calculates the MISR value for region.

Throws SafeRenderer::NXPCalculator::RegionOutOfBounds if the region is out of bounds.
