Parameters

fileName
A String containing the name of the file which contains the stamp image to load.

pageNumber
1-based index of the page from which the stamp image should be loaded.

info A CodecsImageInfo object containing information about the image.

Return Value

The RasterImage object that this method loads.

Remarks

Only EXIF, CMP, JPEG, FlashPix and HEIF/HEIC formats support stamps. However, not all file of these formats contain stamps.

Both ReadStamp(String,Int32) and ReadStamp(String,Int32,CodecsImageInfo) read a thumbnail image from a string and load it into the specified image. The difference is that ReadStamp(String,Int32,CodecsImageInfo) takes a CodecsImageInfo object in order to improve performance.

To create a thumbnail image from any file, use ReadThumbnail.

Note

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