- firstPageIndex
- The zero-based index of the first page to export.
- lastPageIndex
- The zero-based index of the last page to export. A value of -1 means export up to and including the last page in the OCR document.
- stream
- The .NET stream to save the pages to.
- format
- The image file format to use.
- bitsPerPixel
- The bits/pixel value of the result image file.
- firstSavePageNumber
- 1-based index of the first output page. If the output file already exists, then this parameter lets you control which pages to overwrite and/or where to append the new pages.
- pageMode
Determines how to handle the page when saving to multipage formats. This can be one of the following:
Value Meaning CodecsSavePageMode.Append Append the new page(s) to the end of the file. If the file does not exist, this option will create the file and add the pages to it. firstSavePageNumber is not used. CodecsSavePageMode.Insert Insert the new page(s) at the index specified by firstSavePageNumber. CodecsSavePageMode.Replace Replace the page(s) starting at the index specified by firstSavePageNumber. CodecsSavePageMode.Overwrite Overwrite the page(s) starting at the index specified by firstSavePageNumber. CodecsSavePageMode.Append Append the new page(s) to the end of the file. If the file does not exist, this option will create the file and add the pages to it.
