ImGearFileFormats.UpdateDocumentMetadata(sourceStream, destinationStream, metadata)

Parameters

sourceStream: Data stream containing a source image.
destinationStream: Data stream to write the updated image to.
metadata: Document metadata tree to be saved to the new image.

Exception	Description
System.ArgumentNullException	Thrown if the specified stream is null or metadata parameter is null.
ImageGear.Core.ImGearException	Thrown with ImGearErrorCodes.PAGE_NOT_PRESENT error code if the source stream represents DICOM vector waveform data. Thrown with ImGearErrorCodes.CANT_SAVE_FORMAT error code if the metadata cannot be updated due to invalid data in the source stream.

Exception

Description

System.ArgumentNullException

Thrown if the specified stream is null or metadata parameter is null.

ImageGear.Core.ImGearException

Thrown with ImGearErrorCodes.PAGE_NOT_PRESENT error code if the source stream represents DICOM vector waveform data.

Thrown with ImGearErrorCodes.CANT_SAVE_FORMAT error code if the metadata cannot be updated due to invalid data in the source stream.

This method replaces the metadata associated with a document loaded from the source image with the provided metadata and saves the updated image to the destination stream. This method does not replace the metadata assotiated with individual pages. This method does not change the actual pixel data. The structure of the provided metadata tree should correspond to the metadata tree from the source image. This method does not save any metadata tags provided in the metadata tree that are not supported by the source image format. See ImageGear.Core.ImGearMetadataNode for more details about the ImageGear metadata.

This method is only supported for PDF, PS and DICOM file formats.
