Add named value in XMP metadata of EPS | Python
To add a named value to the XMP metadata of an EPS file, follow these steps:
- Initialize an input stream for the input EPS file.
- Create an instance of PsDocument from the previously created input stream.
- Get an instance of XmpMetadata from the PsDocument. If the EPS file does not contain XMP metadata, a new one will be created and populated with values from PS metadata comments, then returned to you.
- Now you can add the named value to the structure metadata fields.
- Initialize an output stream for the output EPS file.
- Save the EPS file with the updated XMP metadata.
Below is a code snippet demonstrating how to add a named value to the XMP metadata in an EPS file in Python:
1from aspose.page.eps import *
2from aspose.page.eps.xmp import *
