BottomMargin Property

Summary
Gets or sets the bottom margin value when rasterizing a document to a raster image.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public double BottomMargin { get; set; } 
@property (nonatomic, assign) double bottomMargin; 
public double getBottomMargin() 
public void setBottomMargin(double value) 
public: 
property double BottomMargin { 
   double get(); 
   void set (    double ); 
} 
BottomMargin # get and set (CodecsRasterizeDocumentLoadOptions)

Property Value

A Double value that indicates the margin value in Unit to use when rasterizing a document to a raster image:. The default value is 0.1.

Value Description
>=0 The value must be greater than or equal to 0.
1.0 Default value in inches.
Remarks

The value of the LeftMargin, TopMargin, RightMargin and BottomMargin are only used when loading RTF and TXT documents. They are not used when loading other document formats such as PDF, XPS, DOCX/DOC, PPTX/PPT and XLSX/XLS.
