From 465028163ee3576380d79de4d1679eeaa833b8c4 Mon Sep 17 00:00:00 2001 From: Martin Kretzschmar Date: Sun, 2 Mar 2003 15:02:20 +0000 Subject: [PATCH] new class, just what the name says, uses GnomeVFSStream for loading * xpdf/nautilus-pdf-property-page.cc, xpdf/nautilus-pdf-property-page.h: new class, just what the name says, uses GnomeVFSStream for loading PDFDocs. * xpdf/GnomeVFSStream.cc, xpdf/GnomeVFSStream.h: BaseStream implementation based on (synchronous) gnome-vfs calls. * xpdf/BonoboStream.cc, xpdf/BonoboStream.h: coding style fixage, include only what's needed. * xpdf/Makefile.am (gnome_pdf_viewer_SOURCES): also compile GnomeVFSStream.{cc,h}, nautilus-pdf-property-page.{cc,h} * xpdf/GNOME_PDF.server.in.in: add stanza for the Property Page. * xpdf/bonobo-application-x-pdf.cc: clean up a bit (gpdf_factory): now we produce the Property Page, too. * xpdf/gpdf-control.cc: include time.h for strftime, mktime. --- pdf/xpdf/GnomeVFSStream.cc | 125 +++++++++++++++++++++++++++++++++++++ pdf/xpdf/GnomeVFSStream.h | 58 +++++++++++++++++ pdf/xpdf/Makefile.am | 10 +-- 3 files changed, 188 insertions(+), 5 deletions(-) create mode 100644 pdf/xpdf/GnomeVFSStream.cc create mode 100644 pdf/xpdf/GnomeVFSStream.h diff --git a/pdf/xpdf/GnomeVFSStream.cc b/pdf/xpdf/GnomeVFSStream.cc new file mode 100644 index 00000000..324e4088 --- /dev/null +++ b/pdf/xpdf/GnomeVFSStream.cc @@ -0,0 +1,125 @@ +//======================================================================== +// +// GnomeVFSStream.cc +// +// Copyright 1996-2002 Glyph & Cog, LLC +// Copyright 2003 Martin Kretzschmar +// +//======================================================================== + +#ifdef __GNUC__ +#pragma implementation +#endif + +#include +#include "config.h" + +#include "GnomeVFSStream.h" +#include "gpdf-g-switch.h" +# include +#include "gpdf-g-switch.h" + +#ifndef NO_DECRYPTION +#include "Decrypt.h" +#endif + +GnomeVFSStream::GnomeVFSStream(GnomeVFSHandle *handleA, Guint startA, + GBool limitedA, Guint lengthA, Object *dictA): + BaseStream(dictA) { + handle = handleA;
