Hello,
I want to find out if a MSOffice document has or not a thumbnail (preview save picture). If yes I would like to save this thumbnail in a .jpeg file, if no, i want to save a temporary preview picture of this document and obtain the thumbnail in a .jpeg file.
Unfortunately this doesn't work. When I do:
def PrintStats(filename):
if not pythoncom.StgIsStorageFile(filename):
print "The file is not a storage file!"
return
# Open the file.
flags = storagecon.STGM_READ | storagecon.STGM_SHARE_EXCLUSIVE
stg = pythoncom.StgOpenStorage(filename, None, flags )
# Now see if the storage object supports Property Information.
try:
pss = stg.QueryInterface(pythoncom.IID_IPropertySetStorage)
except pythoncom.com_error:
print "No summary information is available"
return
# Open the user defined properties.
ps = pss.Open(FMTID_UserDefinedProperties)
props = PIDSI_TITLE, PIDSI_SUBJECT, PIDSI_AUTHOR, PIDSI_CREATE_DTM, PIDSI_THUMBNAIL
data = "" props )
# Unpack the result into the items.
title, subject, author, created, thumbnail = data
print "Title:", title
print "Subject:", subject
print "Author:", author
print "Created:", created.Format ()
print "Thumbnail:", thumbnail
If the thumbnail doesn't exists, it returns None, if It exists, it returns me :
data = "" props )
TypeError: Unsupported property type
Please, somebody can help me?
thanks
Rena
