SaveStamp(RasterImage,string,int,int,int,CodecsSavePageMode) Method (original) (raw)
Summary
Saves a stamp in an existing file with specific options.
Syntax
C#
Objective-C
C++/CLI
Python
Parameters
image
The RasterImage object that contain the thumbnail (stamp) image.
fileName
A String containing the name of an existing image file.
firstPage
1-based index of the first page in image to save.
lastPage
1-based index of the last page in image to save. Pass -1 to save from firstPage to the last page in image.
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 | Description |
|---|---|
| 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]. |
Example
This example will add a stamp to an existing file before reading it back.
