Syntax

Objective-C

C++/CLI

Java

Python

public ColorizeGrayCommand( 
   ColorizeGrayCommandData[] grayColors 
)

- (instancetype)initWithGrayColors:(NSArray<LTColorizeGrayCommandData *> *)grayColors NS_DESIGNATED_INITIALIZER;

public ColorizeGrayCommand( 
   ColorizeGrayCommandData[] grayColors 
);

public: 
ColorizeGrayCommand(  
   array<ColorizeGrayCommandData^>^ grayColors 
)

__init__(self,grayColors) # Overloaded constructor

Parameters

grayColors
Array of ColorizeGrayCommandData class objects that contain the colors used to initialize the class object.

Example

This example loads a 16-bit grayscale image and then colors it.

Java
