Members
| Member | Description |
|---|---|
| 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. |
| Fit | Fit the result 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. |
| FitAlways | Always fit the result 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. |
| FitWidth | Fit the result 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. |
| Stretch | The result 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. |
Example
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. Documents formats such as PDF, XPS, 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 transfromation from this value to determine the final RasterImage width and height.
