UseColorTransform Property

Summary

Gets or sets the flags that indicates whether to convert an RGB image to YUV space before compressing

Syntax

Objective-C

C++/CLI

public bool UseColorTransform { get; set; }

@property (nonatomic, assign) BOOL useColorTransform;

public: 
property bool UseColorTransform { 
   bool get(); 
   void set (    bool value); 
}

Property Value

true to convert to YUV space before compressing. (Default), setting this value to false will not convert to YUV space before compressing.
