C++/CLI
Python
- (nullable LTRasterImage *)readStampFromFile:(NSString *)_fileName_
pageNumber:(NSInteger)_pageNumber_
error:(NSError **)error
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, HEIF/HEIC, and PNG formats support stamps. However, not all files 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.
