Description

Created attachment 137181 Add type annotation to poppler_document_new_from_data()

In Poppler-0.18.gir poppler_document_new_from_data() is defined as following:

  <constructor name="new_from_data"
               c:identifier="poppler_document_new_from_data"
               throws="1">
    <doc xml:space="preserve">Creates a new #PopplerDocument.  If %NULL is returned, then @error will be

set. Possible errors include those in the #POPPLER_ERROR and #G_FILE_ERROR domains.</doc> <return-value transfer-ownership="full"> A newly created #PopplerDocument, or %NULL</doc> </return-value> <parameters> <parameter name="data" transfer-ownership="none"> the pdf data contained in a char array</doc> </parameter> <parameter name="length" transfer-ownership="none"> the length of #data</doc> </parameter> password to unlock the file with, or %NULL</doc> </parameter> </parameters> </constructor>

This definition validates data as UTF-8 string when read a PDF data using poppler_document_new_from_data() via gobject-introspection. In general, PDF data is not UTF-8 string. So we should treat parameter data as binary.

I wrote tiny patch and confirm that the poppler_document_new_from_data() definition is updated after applied this patch. However, I'm not familiar with gobject-introspection in honest.
