ForceBackgroundColor Property

Summary

Enables or disables the use of the BackgroundColor when rasterizing vector image files.

Syntax

Objective-C

C++/CLI

Java

Python

public bool ForceBackgroundColor { get; set; }

@property (nonatomic, assign) BOOL forceBackgroundColor;

public boolean isForceBackgroundColor() 
public void setForceBackgroundColor(boolean forceBGColor)

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

ForceBackgroundColor # get and set (CodecsVectorLoadOptions)

Property Value

Value	Description
true	To fill the resulting raster image with BackgroundColor.
false	To use the color specified in the vector image file. The default value is false.

Remarks

Set this property to true to override the background color specified in the file when rasterizing vector image files.
