Read a .SLA file into memory

[aoloe]

Questions:

• Is it possible to read in this structure without having to write a 6000 LOC file?

Get the Scribus code over, that allows to read a current .SLA file into memory

• scribus.cpp ScribusMainWindow::loadDoc(QString fileName)

• if file exists → fileloader.cpp FileLoader::FileLoader(const QString & fileName)

  • fileLoader->testFile() return int -1 if the file doesn't exist or any other error has occurred, 0 for the old Format, 1 for the new Format, 2 for EPS and PS files, 3 for SVG files and 4 for PDF files (based on the extension).
  • get cms profiles dir
  • get fonts dir
  • new ScribusDoc():

  doc=new ScribusDoc();
  doc->is12doc=is12doc;
  doc->appMode = modeNormal;
  doc->HasCMS = false;
  doc->OpenNodes.clear();
  doc->setLoading(true);
  ScribusWin* w = new ScribusWin(mdiArea, doc);
  w->setMainWindow(this);
  view = new ScribusView(w, this, doc);
  doc->setGUI(true, this, view);
  view->setScale(prefsManager->displayScale());
  w->setView(view);
  alignDistributePalette->setDoc(doc);
  ActWin = w;
  doc->WinHan = w;
  w->setSubWin(mdiArea->addSubWindow(w));
  w->setUpdatesEnabled(false);
  view->updatesOn(false);
  doc->SoftProofing = false;
  doc->Gamut = false;
  setScriptRunning(true);
  bool loadSuccess = fileLoader->loadFile(doc);

  • fileLoader->loadFile(doc):

  • read the scribus preferences:

    QList::const_iterator it; if (findFormat(m_fileType, it)) { switch (m_fileType) { case FORMATID_SLA13XIMPORT: case FORMATID_SLA134IMPORT: case FORMATID_SLA150IMPORT: { it->setupTargets(currDoc, 0, currDoc->scMW(), currDoc->scMW()->mainWindowProgressBar, &(prefsManager->appPrefs.fontPrefs.AvailFonts)); ret=it->loadFile(m_fileName, LoadSavePlugin::lfCreateDoc); } break;

  • the interface FileFormat (the it above) is defined in loadsaveplugin.cpp
    • for 1.5, the file format is defined in plugins/fileloader/scribus150format/scribus150format.h/.cpp
    • for 1.3.4 in plugins/fileloader/scribus134format/scribus134format.h/.cpp
    • we won't support older formats.
  • Scribus150Format::loadFile():
    • the file can be gzipped or not
    • read the first few bytes to know if it's a 1.5 SLA
