Summary
Initializes a new ColorizeGrayCommand class object with explicit parameters.
Syntax
C#
Objective-C
C++/CLI
Java
Python
- (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.
