VideoMASTER_Vectorscope

Description:

This function measures color bar vectors from a Composite or S-Video signal in the video buffer, and outputs the vectors in a form that may be displayed in the same way as in the User Interface. Indicators for displaying the vectors can be obtained by copying the Vectors Graticules pict ring and the Vectors Graph XY graph indicators on the Graphical Display page.

Syntax:

typedef enum {
    Scope_Standard, Scope_Camera
} ScopeMeasurementTypes;



typedef enum {
    VPlus, VMinus, VplusMinus
} PALLineTypes;



typedef struct {
    long Line;
    long CompositeChannel;
    long LinesToAverage;
} LineSelectionVectorscope;



void VideoMASTER_Vectorscope(
    ErrorCluster *errorIn,
    LVBoolean *autoAdjustFsc,
    LVBoolean *showNominalVectors,
    ScopeMeasurementTypes measurementType,
    PALLineTypes selectPALLineType,
    LineSelectionVectorscope *lineSelection,
    ErrorCluster *errorOut,
    double *blackLevel,
    double *whiteLevel,
