Re: [pdf-devel] Filter params type

[jemarch]

Hello JP.

   I've just started the lzw filter implementation :) It has an
   "EarlyChange" param, and I was trying to guess what the param's
   hash maps.

   I think that the best behaviour is to map pdf_char_t* to pdf_char_t* and
   let the filter decode the param content,

What do you mean with "to map" in this context? The contents of the
parameters hash table for the LZW decoding filter would be something
like:

       key                        value

  ... other fields
  "EarlyChange"                 (void *)pdf_u32_t

Note that we are going to implement the PDF dictionary objects in top
of a pdf-hash variable, and we will have type checking in the
implementation of pdf_dict_t.
