BitsPerPixel Property

Summary

Gets or sets the target bits per pixel for the resulting raster image when rasterizing vector image files.

Syntax

Objective-C

C++/CLI

Java

Python

public int BitsPerPixel { get; set; }

@property (nonatomic, assign) NSInteger bitsPerPixel;

public int getBitsPerPixel() 
public void setBitsPerPixel(int bitsPerPixel)

public: 
property int BitsPerPixel { 
   int get(); 
   void set (    int ); 
}

BitsPerPixel # get and set (CodecsVectorLoadOptions)

Property Value

The target bits per pixel for the resulting raster image when rasterizing vector image files. The default value is 0.

Remarks

A vector image file format usually does not have a physical size. The user can specify a viewport (physical size up to which the drawing can be rendered) ViewWidth and ViewHeight. How the drawing is to be rendered inside this viewport depends on the current viewport mode set with ViewMode. Default viewport size is 640x480 pixels.
