Re: [Swftools-common] Trouble when gfx rendering a protected PDF file. Application exits.

[Chris Pugh]

Hi,

Unfortunately I'm not familiar with the gfx module,  however
here's a couple of suggestions, from taking ab brief look at,

    http://www.swftools.org/gfx.html

Use,

    getInfo(...)

to check for a protected ( how? ) document?

Raise the logging level of the gfx module with

verbose(...)
    verbose(level)

to get a handle on what's actually happening?

HTH a little.

Regards,


Chris.
