PDFs with forms

[lesolorzanov]

I tried this with a PDF with a form and the form stops working, it is rasterized, I was wondering if this was taken into account. Is pretty nice otherwise.

First, let's clarify:

• "Rasterize" means to convert to pixel graphics. If you zoom in far enough on something rasterized, you'll see it is pixelated, a less sharp image.
• "Flatten" means to merge the contents of a PDF form into the document itself, making it non-editable.

pdf-sign should not rasterize anything, if it does then it's a bug. It does however flatten before signing, by design. This is since you usually would not want to change anything in the form after signing, even accidentally. You can turn off flattening with the --no-flatten command-line option.

I noticed that the help text does not inform the user that --flatten is on by default. This should be fixed.

@lesolorzanov Could you clarify if the behavior you see is rasterization or flattening? Did the above explanation help you?
