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:
- 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 doesn’t 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 properties to the metadata fields.
- Initialize an output stream for the output EPS file.
- 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:
1# The path to the documents directory.
2data_dir = Util.get_data_dir_working_with_xmp_metadata_in_eps()
3# Initialize an EPS file input stream
4ps_stream = open(data_dir + "add_simple_props_input.eps", "rb",)
5# Create a PsDocument instance from stream
6document = PsDocument(ps_stream)
7
8try:
9 # 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)
10 xmp = document.get_xmp_metadata()
11
12 #Change the XMP metadata values
13
14
15 now = datetime.utcnow()
16
17 # Add an Integer poperty
18 xmp.add("xmp:Intg1", XmpValue(111))
19
20 # Add a DateTime poperty
21 xmp.add("xmp:Date1", XmpValue(now))
22
23 # Add a Double poperty
24 xmp.add("xmp:Double1", XmpValue(111.11))
25
26 # Add a String poperty
27 xmp.add("xmp:String1", XmpValue("ABC"))
28
29 # Save the EPS file with the changed XMP metadata
30
31 # Create an ouput stream
32 with open(data_dir + "add_simple_props_output.eps", "wb") as out_ps_stream:
33 # Save the EPS file
34 document.save(out_ps_stream)
