Functions

bool Isis::IsSpecial (const double d)
 Returns if the input pixel is special.
 
bool Isis::IsSpecial (const float f)
 Returns if the input pixel is special.
 
bool Isis::IsValidPixel (const double d)
 Returns if the input pixel is valid.
 
bool Isis::IsNullPixel (const double d)
 Returns if the input pixel is null.
 
bool Isis::IsHighPixel (const double d)
 Returns if the input pixel is one of the high saturation types.
 
bool Isis::IsLowPixel (const double d)
 Returns if the input pixel is one of the low saturation types.
 
bool Isis::IsHrsPixel (const double d)
 Returns if the input pixel is high representation saturation.
 
bool Isis::IsHisPixel (const double d)
 Returns if the input pixel is high instrument saturation.
 
bool Isis::IsLisPixel (const double d)
 Returns if the input pixel is low instrument saturation.
 
bool Isis::IsLrsPixel (const double d)
 Returns if the input pixel is low representation saturation.
 
double Isis::TestPixel (const float t)
 Converts float pixels to double pixels with special pixel translations.
 
float Isis::TestPixel (const double t)
 Converts double to float with special pixel translations and care for overflows (underflows are assumed to cast to 0!)
 
QString Isis::PixelToString (double d, double precision=8)
 Takes a double pixel value and returns the name of the pixel type as a string.
 
double Isis::StringToPixel (const QString &str)
 Takes the name of the pixel type as a string and returns a double pixel value.
