Hi Casper,
sorry if It sounds daft question, but I'm a new mitk's user.
I have two functions. One of them generates data (input and output images)
and the other gets that data and manipulates some filters on them like this:
void myClass::GenerateData()
{
Mitk::Image::ConstPointer inputImage = this->GetOutput(0);
Mitk::Image::Pointer outputImage = this->GetOutput();
MyFunction( inputImage, m_inputVal1, outputImage);
}
void myFunction(const mitk::Image* inputMitkImage, int val1,
mitk::Image::Pointer outputImage)
{
vtkImageData* vtkImage = mitkImage->GetVtkImage(); // this returns error
regarding the const pointer //which can’t change the image
}
So, I have two questions:
1) Because the function getInput(0) can return only a constPointer- (I get
errors if I don't manipulate in this way) so I must send the inputImage to
my Function as I did (with a const pointer) and then, how can I manipulate
my filters on the that image?
2) How can I send to myFunc a multiple number of images?
Is my intuition right that it should be something like this?
void myClass::GenerateData()
{
Mitk::Image::ConstPointer inputImage_1 = this->GetOutput(0); //to insert
the first selected image
Mitk::Image::ConstPointer inputImage_2 = this->GetOutput(1); //to insert
the second selected image
Mitk::Image::ConstPointer inputImage_3 = this->GetOutput(2); //to insert
the third selected image
Mitk::Image::Pointer outputImage = this->GetOutput();
MyFunction( inputImage_1, inputImage_2, inputImage_3, m_inputVal1,
outputImage);
}
and how should myFunction signature look like (the const pointer is a very
sensitive issue for me :-), how can I avoid from writing him at the first
place)?
A lot of thanks,
Miri
