int CanReadFile(VTK_FILEPATH const char *fname) override
Is the given file a HDR file?
const char * GetDescriptiveName() override
Return a descriptive name for the file format that might be useful in a GUI.
void FillOutPtrNoRLE(int *outExt, float *&outPtr, std::vector< unsigned char > &lineBuffer)
static void XYZ2RGB(const float convertMatrix[3][3], float &r, float &g, float &b)
Conversion from xyz to rgb float using the 3x3 convert matrix.

void RGBE2Float(unsigned char rgbe[4], float &r, float &g, float &b)
Standard conversion from rgbe to float pixels.
void HDRReaderUpdate(vtkImageData *data, float *outPtr)
bool SwappedAxis
If true, the Y axis is the X, and the height and width has been swapped.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void ExecuteInformation() override
bool ReadHeaderData()
Read the header data and fill attributes of HDRReader, as well as DataExtent.
const char * GetFileExtensions() override
Get the file extensions for this format.
bool HasError(istream *is)
If the stream has an error, close the file and return true.
