BitsPerPixel Property

Summary

Bits per pixel to use when saving the document.

Syntax

C++/CLI

Java

Python

public int BitsPerPixel { get; set; }

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

public int getBitsPerPixel() 
public void setBitsPerPixel(int value)

BitsPerPixel # get and set (SaveDocumentOptions)

Property Value

The bits per pixel to use when saving the document. Default value is 0.

Remarks

If the value of BitsPerPixel is the default 0, then the document will be saved using the bits per pixel of the original document.
