just always return true, ret_value is always overwritten here...

[ivandavid, 2014/07/08 01:07:42]

Done.

[ivandavid, 2014/07/08 01:07:42]

Oops. Didn't mean to assign it to true there. It actually shouldn't always
return true. I now assign it correctly.

[Lei Zhang, 2014/07/08 01:11:37]

I think what you want is:

if (!doc)
  return false;
bool retval == FPDF_GetPageSizeByIndex(doc, index, width, height) != 0;
FPDF_CloseDocument(doc);
return retval;

[Dan Beam, 2014/07/08 04:25:13]

if we're gonna keep this code, s/retval ==/success =/g

[ivandavid, 2014/07/08 23:24:21]

Done.
