Add properties in XMP metadata of EPS | Python

To add properties to the XMP metadata of an EPS file, you’ll need to 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 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 add properties to the 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 properties to the XMP metadata of an EPS file using 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 an EPS file input stream
ps_stream = open(data_dir + "add_simple_props_input.eps", "rb",)
# Create a PsDocument instance from stream
document = PsDocument(ps_stream)

try:
    # Get XMP metadata. If EPS file doesn't contain any 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
    
    
    now = datetime.utcnow()
    
    # Add an Integer poperty
    xmp.add("xmp:Intg1", XmpValue(111))
    
    # Add a DateTime poperty
    xmp.add("xmp:Date1", XmpValue(now))
    
    # Add a Double poperty
    xmp.add("xmp:Double1", XmpValue(111.11))
    
    # Add a String poperty
    xmp.add("xmp:String1", XmpValue("ABC"))
    
    # Save the EPS file with the changed XMP metadata
    
    # Create an ouput stream
    with open(data_dir + "add_simple_props_output.eps", "wb") as out_ps_stream:
        # Save the EPS file
        document.save(out_ps_stream)
    
finally:
    ps_stream.close()
