This patch makes the UUIDs in the XMP header optional, depending on the
|
|
setting of the environment variable GS_GENERATE_UUIDS.
|
|
|
|
If the environment variable GS_GENERATE_UUIDS is set to "0" or "no", it will
|
|
not write out the Document UUID field and also will write the Instance ID
|
|
field value as "".
|
|
|
|
Upstream does not want to do this.
|
|
|
|
