CodecsRasterizeDocumentSizeMode Enumeration

Summary

Specifies the transformation to use when converting the logical size specified in the current document rasterization options to the final physical raster image size.

Syntax

Objective-C

WinRT C#

C++

public enum CodecsRasterizeDocumentSizeMode

Public Enum CodecsRasterizeDocumentSizeMode

public enum CodecsRasterizeDocumentSizeMode

typedef NS_ENUM(NSInteger, LTCodecsRasterizeDocumentSizeMode)

public enum CodecsRasterizeDocumentSizeMode

Leadtools.Codecs.CodecsRasterizeDocumentSizeMode = function() { }; 
Leadtools.Codecs.CodecsRasterizeDocumentSizeMode.prototype = {<br/> 
  None = 0, 
    Fit = 1, 
    FitAlways = 2, 
    FitWidth = 3,

 };

public enum class CodecsRasterizeDocumentSizeMode

Members

Value	Member	Description
0	None	Use the original document width and height. No transformation will be performed and CodecsRasterizeDocumentLoadOptions.PageWidth and CodecsRasterizeDocumentLoadOptions.PageHeight are not used. The final RasterImage will have a width or height value equals to the original document size.
1	Fit	Fit the resulting raster image into CodecsRasterizeDocumentLoadOptions.PageWidth and CodecsRasterizeDocumentLoadOptions.PageHeight while maintaining the aspect ratio. If the original document size is smaller than the requested page size, no transformation is performed. The final RasterImage will have a width or height equal to or less than the requested page width or height but not greater.
2	FitAlways	Always fit the resulting raster image into CodecsRasterizeDocumentLoadOptions.PageWidth and CodecsRasterizeDocumentLoadOptions.PageHeight while maintaining the aspect ratio. If the original document size is smaller than the requested page size, then the result image is scaled up. The final RasterImage will have a width or height equal to the requested page width or height. Not less and not greater.
3	FitWidth	Fit the resulting raster image width into CodecsRasterizeDocumentLoadOptions.PageWidth while maintaining the aspect ratio. The image height will be calculated based on the transformation and CodecsRasterizeDocumentLoadOptions.PageHeight is not used. The final RasterImage will have a width equal to the requested page width. The height depends on the original document height.
4	Stretch	The resulting raster image width and height will be exactly equal to CodecsRasterizeDocumentLoadOptions.PageWidth and CodecsRasterizeDocumentLoadOptions.PageHeight. Aspect ratio might be different than the original document. The final RasterImage will have a width and height equal to the requested page width and height.

Remarks

The CodecsRasterizeDocumentSizeMode enumeration type is used as the value for CodecsRasterizeDocumentLoadOptions.SizeMode property.

LEADTOOLS provides support for loading a document as a raster image. Document formats such as PDF, XPS, DOCX/DOC, PPTX/PPT, XLSS/XLS, RTF and Text do not contain physical width, height or resolution. It is up to the loader (in this case, the RasterCodecs object) to specify the transformation from logical coordinates to physical pixels through a process called rasterization. For more information, refer to CodecsRasterizeDocumentLoadOptions.

You can use the CodecsRasterizeDocumentLoadOptions.SizeMode property to control how to use CodecsRasterizeDocumentLoadOptions.PageWidth and CodecsRasterizeDocumentLoadOptions.PageHeight to control the final raster image size. LEADTOOLS will determine the original document size (a value that can be obtained in CodecsDocumentImageInfo.PageWidth and CodecsDocumentImageInfo.PageHeight and then apply the transformation from this value to determine the final RasterImage width and height.

Example

For an example, refer to CodecsRasterizeDocumentLoadOptions.
