Flags Property

Summary

Flags that indicate the channel that will be used, the treatment of the input pixel values, the mathematical operation, and the treatment of the output pixel values.

Syntax

Objective-C

C++

Java

public ApplyMathematicalLogicCommandFlags Flags { get; set; }

Public Property Flags As ApplyMathematicalLogicCommandFlags

@property (nonatomic, assign) LTApplyMathematicalLogicCommandFlags flags

public int getFlags() 
public void setFlags(int value)

public:  
   property ApplyMathematicalLogicCommandFlags^ Flags 
   { 
      ApplyMathematicalLogicCommandFlags^ get() 
      void set(ApplyMathematicalLogicCommandFlags^ value) 
   }

Property Value

Flags that indicate the channel that will be used, the treatment of the input pixel values, the mathematical operation, and the treatment of the output pixel values. Use a bitwise OR ( ¦ ) to specify one flag from each group.

Remarks

Calculating Master Channel Values

In order to speed up widely used image processing filters in LEADTOOLS, the grayscale value (master channel) of a colored image is calculated using the following formulas:

#define CalcGrayValue(r, g, b) ((L_UCHAR)(((L_UCHAR) (((2 * (L_UINT) (r)) + (5 * (L_UINT) (g)) + (L_UINT) (b) + 4) / 8)))) 
#define CalcGrayValue16(r, g, b) ((L_UINT16) (((2 * (L_UINT32) (r)) + (5 * (L_UINT32) (g)) + (L_UINT32) (b) + 4) / 8)) 
#define CalcGrayValue32(r, g, b) ((L_UINT32) (((2 * (L_UINT32) (r)) + (5 * (L_UINT32) (g)) + (L_UINT32) (b) + 4) / 8))
