CodecsRasterizeDocumentUnit Enumeration

Summary
Specifies the unit of a document page width, height or margins.
Syntax
C#
Objective-C
C++/CLI
Java
Python
public enum CodecsRasterizeDocumentUnit   
typedef NS_ENUM(NSInteger, LTCodecsRasterizeDocumentUnit) { 
 LTCodecsRasterizeDocumentUnitPixel = 0,  
 LTCodecsRasterizeDocumentUnitInch = 1,  
 LTCodecsRasterizeDocumentUnitMillimeter = 2 
}; 
public enum CodecsRasterizeDocumentUnit 
public enum class CodecsRasterizeDocumentUnit   
class CodecsRasterizeDocumentUnit(Enum): 
   Pixel = 0 
   Inch = 1 
   Millimeter = 2
Members
ValueMemberDescription
0Pixel

The page width, height or margins are in pixels.

1Inch

The page width, height or margins are in inches.

2Millimeter

The page width, height or margins are in millimeters.

Remarks

The CodecsRasterizeDocumentUnit is used to specify the unit of a document page width, height or margins. By using this enumeration, you can define document (logical) sizes in pixels, inches or millimeters.

The CodecsRasterizeDocumentUnit enumeration is used as the value for the following class members:

Class Member Units
CodecsDocumentImageInfo.Unit

As the units for CodecsDocumentImageInfo.PageWidth and CodecsDocumentImageInfo.PageHeight
CodecsRasterizeDocumentLoadOptions.Unit

As the units for CodecsRasterizeDocumentLoadOptions.PageWidth, CodecsRasterizeDocumentLoadOptions.PageHeight, CodecsRasterizeDocumentLoadOptions.LeftMargin, CodecsRasterizeDocumentLoadOptions.TopMargin, CodecsRasterizeDocumentLoadOptions.RightMargin and CodecsRasterizeDocumentLoadOptions.BottomMargin
