Optimierung

Optimiere ein PDF Dokument für die Archivierung

Verwende das Archivierungs-Profil um die Dateigrösse zu reduzieren ohne Informationsverlust - einer typischen Vorgabe für die Archivierung. Entferne redundante Informationen, führe eingebettete Schriften zusammen und reduziere sie auf die verwendeten Glyphen. Optimiere Ressourcen und komprimiere Bilder typenabhängig.

C# sample:

// Create the optimizer
using (Optimizer optimizer = new Optimizer())

    // Choose the optimization profile for archiving
    optimizer.Profile = PDFOptimizationProfile.eOptimizationProfileArchive;

PDF Dokument mit Mixed Raster Content (MRC) optimieren

Reduziere die Dateigrösse von Dokumenten mit grossen Bildern, z.B. gescannten Seiten, unter Beibehaltung der Lesbarkeit von Text. Dies wird durch die Trennung der Bilder in einen Vordergrund, einen Hintergrund und eine Maskenebene erreicht. Die Vordergrund- und Hintergrundebenen werden stark heruntergerechnet und komprimiert. Die Textinformationen werden in der Maske mit einem verlustfreien Kompressionstyp gespeichert. Darüber hinaus werden redundante Objekte entfernt, Ressourcen optimiert und eingebettete Schriften zusammengeführt.

C# sample:

// Create the optimizer
using (Optimizer optimizer = new Optimizer())
{
    // Choose the optimization profile for MRC
    optimizer.Profile = PDFOptimizationProfile.eOptimizationProfileMRC;

    // Set MRC foreground and background layer resolution
    optimizer.MrcLayerResolutionDPI = resolution;

    // Open input file
    if (!optimizer.Open(inputPath, ""))

            "{1} (ErrorCode: 0x{2:x}).", inputPath, optimizer.ErrorMessage, optimizer.ErrorCode));

    // Save output file

Optimieren von Bildern in PDF Dokument

Reduziere die Grösse einer PDF Datei, indem Sie eingebettete Bilder herunterrechnen und neu komprimieren.

PDF Dokument für den Druck optimieren

Vermeide drucktechnische Probleme mit PDF Dokumenten. Reduziere die Gesamtdateigrösse und führe Schriftarten und Schriftprogramme zusammen, um kleinere Spooldateien zu erstellen und den Speicherverbrauch des Druckers zu reduzieren. Konvertiere Farben in CMYK. Entferne oder ändere keine Informationen, wie z.B. die Bildauflösung, die für eine klar definierte Wiedergabe erforderlich sind.

PDF Dokument für das Web optimieren

Verringere die Dateigrösse eines PDFs, um den Speicherbedarf auf einem Webserver und die Downloadzeiten zu reduzieren. Diese Optimierung kann zu geringen visuellen Verlusten führen.
