Parameters

image

The Leadtools.RasterImage object that contain the thumbnail (stamp) image.

stream

A System.IO.Stream containing the data 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	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.

The stamp will be written to last page in the file. If that page already has a stamp, it will be overwritten; If the file to which the stamp is being written does not exist, an exception will occur.

This method works for regular JPEG files and Exif JPEG files. For regular JPEG files, the stamp saved is always uncompressed and can be 8 or 24 bits per pixel. The stamp can be any width and height, but the stamp data and stamp header must completely fit in an APP0 marker. Therefore, the size must be less than 64k bytes (0xFFFF).

For Exif JPEG files, the stamps can be uncompressed or JPEG compressed and must be 24 bits per pixel. Exif JPEG stamps are supposed to be 160 x 120. However, LEADTOOLS can save and read Exif JPEG stamps of other dimensions. The stamp, along with other information such as the TIFF_HEADER, 0th IFD, 1st IFD, etc. must completely fit in an APP1 marker. Therefore, the size must be less than 64k bytes (0xFFFF).

NOTE: At this time, there are no multipage formats that support stamps.
