AutoColorLevelCommandType Enumeration

Summary

Enumeration flags that identify the type of leveling to perform.

Syntax

Objective-C

C++/CLI

Java

Python

public enum AutoColorLevelCommandType

typedef NS_ENUM(NSInteger, LTAutoColorLevelCommandType) { 
 LTAutoColorLevelCommandTypeNone = 0x0000,  
 LTAutoColorLevelCommandTypeLevel = 0x00000001,  
 LTAutoColorLevelCommandTypeContrast = 0x00000002,  
 LTAutoColorLevelCommandTypeIntensity = 0x00000003,  
};

public final class AutoColorLevelCommandType 
    extends java.lang.Enum<AutoColorLevelCommandType>

public enum class AutoColorLevelCommandType

class AutoColorLevelCommandType(Enum): 
   None = 0 
   Level = 1 
   Contrast = 2 
   Intensity = 3

Members

Value	Member	Description
0	None	No change.
1	Level	Perform leveling on the individual R, G and B channels, treating each of the R, G and B channels as a separate entity. It introduces color cast on the image.
2	Contrast	Perform leveling on the Master channel (the grayscale values of the pixels). No color cast will be introduced. 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))
3	Intensity	Perform leveling on the RGB channel (the sum of the R, G, and B channels). No color cast will be introduced.
