Add XML namespace in XMP metadata of EPS |Python
To add an XML namespace to the XMP metadata of an EPS file, you need to perform the following 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 a new XML namespace to the metadata.
- Initialize an output stream for the output EPS file.
- Save the EPS file with the updated XMP metadata.
The following code example demonstrates how to add an XML namespace to the XMP metadata in an EPS file using Python:
1from aspose.page.eps import *
2from aspose.page.eps.xmp import *
