Change simple values in XMP EPS metadata |Python

In order to change simple values in XMP metadata of EPS file you will need to take several 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 doesn’t 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 change values of metadata fileds.
5. Initialize an output stream for the output EPS file.
6. Save EPS file with new XMP metadata.

Here is a code snippet that shows how to change simple values in XMP metadata of EPS file in Python:

from aspose.page.eps import *
from aspose.page.eps.xmp import *
from datetime import datetime
from util import Util

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

try:
    # Get XMP metadata. If 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 the XMP metadata values
    
    # Change ModifyDate value
    now = datetime.utcnow()
    #xmp["xmp:ModifyDate"] = now
    xmp.add("xmp:ModifyDate", now)
    
    # Change Creator value
    value = XmpValue("Aspose.Page")
    xmp.add("dc:creator", value)
    
    # Change Title value
    value = XmpValue("(PAGEJAVA-29.eps)")
    xmp.add("dc:title", value)
    
    # Save EPS file with changed XMP metadata
    
    # Create an ouput stream
    with open(data_dir + "change_values_output.eps", "wb") as out_ps_stream:
        # Save EPS file
        document.save(out_ps_stream)
    
finally:
    ps_stream.close()
