C++ (Cpp) ImagePtr Examples

Example #1

File: cxViewsFixture.cpp Project: normit-nav/CustusX

void ViewsFixture::applyParameters(cx::ImagePtr image, const ImageParameters *parameters)
{
	if (!parameters)
		return;
	image->getTransferFunctions3D()->setLLR(parameters->llr);
	image->getTransferFunctions3D()->setAlpha(parameters->alpha);
}

Example #2

File: cxtestDicomConverter.cpp Project: normit-nav/CustusX

	void checkImagesEqual(cx::ImagePtr input1, cx::ImagePtr input2)
	{
		REQUIRE(input1);
		REQUIRE(input2);
		CHECK(input1->getModality() == input2->getModality());
		CHECK(cx::similar(input1->getInitialWindowLevel(), input2->getInitialWindowLevel()));
		CHECK(cx::similar(input1->getInitialWindowWidth(), input2->getInitialWindowWidth()));
		CHECK(cx::similar(input1->get_rMd(), input2->get_rMd(), 1.0E-2));
		checkImagesEqual(input1->getBaseVtkImageData(), input2->getBaseVtkImageData());
	}

Example #3

File: cxtestImageEnveloper.cpp Project: SINTEFMedtek/CustusX

void checkImages(cx::ImagePtr input, cx::ImagePtr expected)
{
	{
		INFO(getDim(input) << " == " << getDim(expected));
		CHECK(cx::similar(getDim(input), getDim(expected)));

		CHECK(cx::similar(getSpacing(input), getSpacing(expected)));
	}
	CHECK(input->getParentSpace() == expected->getParentSpace());
	// removed: image is not necessarily black. The size is what matters.
	//CHECK(cxtest::Utilities::getFractionOfVoxelsAboveThreshold(input->getBaseVtkImageData(), 0) == Approx(0));
}
