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:

1. Initialize an input stream for the input EPS file.
2. Create an instance of PsDocument from the previously created input stream.
3. 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.
4. Now you can add the named value to the structure metadata fields.
5. Initialize an output stream for the output EPS file.
6. 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:

 # The path to the documents directory.
data_dir = Util.get_data_dir_working_with_xmp_metadata_in_eps()
# Initialize an EPS file input stream
ps_stream = open(data_dir + "add_named_value_input.eps", "rb",)
# Create PsDocument instance from stream
document = PsDocument(ps_stream)

try:
    # Get XMP metadata. If the EPS file doesn't contain XMP metadata we get a new one filled with values from PS metadata comments (%%Creator, %%CreateDate, %%Title etc)
    xmp = document.get_xmp_metadata()
    
    #Change XMP metadata values
    
    # Add a named value to "xmpTPg:MaxPageSize" structure.
    xmp.add_named_value("xmpTPg:MaxPageSize", "stDim:newKey", XmpValue("NewValue"))
    
    # Save the EPS file with changed XMP metadata
    
    # Create an ouput stream
    with open(data_dir + "add_named_value_output.eps", "wb") as out_ps_stream:
        # Save EPS file
        document.save(out_ps_stream)
    
finally:
    ps_stream.close()
