Add XMP metadata to EPS file using Python

To add XMP metadata to an EPS file using Python, you 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 view the values of the metadata fields.
5. Initialize an output stream for the output EPS file.
6. Save EPS file with new XMP metadata.

The following code snippet shows how to add XMP metadata to EPS file in Python:

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

# The path to the documents directory.
data_dir = Util.get_data_dir_working_with_xmp_metadata_in_eps()
# Initialize EPS file input stream
ps_stream = open(data_dir + "add_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 new one filled with values from PS metadata comments (%%Creator, %%CreateDate, %%Title etc)
    xmp = document.get_xmp_metadata()
    
    # Check metadata values extracted from PS metadata comments and set up in new XMP metadata
    
    # Get "CreatorTool" value
    if xmp.contains("xmp:CreatorTool"):
        print("CreatorTool: " + xmp.get_value("xmp:CreatorTool").to_string_value())
    
    # Get "CreateDate" value
    if xmp.contains("xmp:CreateDate"):
        print("CreateDate: " + xmp.get_value("xmp:CreateDate").to_string_value())
    
    # Get "format" value
    if xmp.contains("dc:format"):
        print("Format: " + xmp.get_value("dc:format").to_string_value())
    
    # Get "title" value
    if xmp.contains("dc:title"):
        print("Title: " + xmp.get_value("dc:title").to_array()[0].to_string_value())
    
    # Get "creator" value
    if xmp.contains("dc:creator"):
        print("Creator: " + xmp.get_value("dc:creator").to_array()[0].to_string_value())
    
    # Get "MetadataDate" value
    if xmp.contains("xmp:MetadataDate"):
        print("MetadataDate: " + xmp.get_value("xmp:MetadataDate").to_string_value())
    
    # Save EPS file with new XMP metadata
    
    # Create ouput stream
    with open(data_dir + "add_output.eps", "wb") as out_ps_stream:
        # Save EPS file
        document.save(out_ps_stream)
    
finally:
    ps_stream.close()
