Re: [Paraview] Converting an image from float to unsigned char
Hi David, Data type casting is very application dependent. Adding a casting-capability to a data writer could be an idea, but it means that you add some functionalities to an object that was not intended to handle them. More risky: it means that you will write data that are not those you put in the writer! Integrate vtkImageCast in ParaView is an easy task (it is done in Peavip), either through a compiled plugin or an XML.

Every time I use a programmable filter I think I am missing a built in function. Could the PNGWriter be hooked up to a vtkImageCast easily?

[Paraview] Converting an image from float to unsigned char
I have a mhd image of floats that I am trying to write as a PNG. Of course the writer complains that the only allowable inputs are unsigned char images. Is there a way to convert image types inside ParaView (I would want to scale the floats to be in the range [0,255] before casting)?
