Johannes Schauer Marin Rodrigues	cb2644c34f	do not include thumbnails in the output by default unless --include-thumbnails is used ... This is relevant for the MPO format which otherwise would result in PDF files containing the same image in different sizes multiple times. With this change, the default is to only have a single page containing the full MPO. This means that extracting that MPO also gets the thumbnails back. With the --include-thumbnails option, each frame gets stored on its own page as it is done for multi-frame GIF, for example. Closes: #135	2023-06-11 07:31:07 +02:00
Patrick McCarty	81502f21af	Convert creation/modification dates to UTC (fixes #155) ... Ensure that timezones are correctly interpreted in the input by calling `.astimezone()` as appropriate on datetime objects, and store the resulting date fields as UTC. One could argue that datetimes in the local timezone be stored in the PDF, but then the date string handling becomes more complicated; the PDF and XMP date specs both use the `Z` suffix to indicate UTC time, but other +/- offsets require different syntax between the two specs.	2023-06-10 17:53:03 -07:00
