MHTML in Bild konvertieren – Cloud-SDKs und REST-API MHTML zum Bild Aspose.HTML Cloud v4.0 bietet die einfachste API zum Konvertieren von MHTML -Dokumenten in Bilddateiformate mit hoher Qualität, einfach und schnell.
Das MHTML-Format hat als XML-basiertes E-Book-Format an Popularität gewonnen und ist darauf ausgelegt, die Darstellung des Inhalts an das Lesegerät anzupassen. Es wird als Archivdatei implementiert, die aus XHTML-Dateien mit Inhalten, Bildern und anderen unterstützenden Dateien besteht. Manchmal ist es erforderlich, ein Bild anstelle von MHTML-Dokumenten zu erhalten, z. B. um sie portabel zu machen und sie einfach auf verschiedenen Geräten zu teilen, eine Bildergalerie aus E-Books zu erstellen usw.
Der Artikel erklärt in einer Reihe von Codebeispielen, wie man ein MHTML-Dokument in Bilddateiformate wie JPEG , PNG , GIF , TIFF oder BMP mit Aspose.HTML Cloud SDKs und REST API-Aufrufen. SDKs sind in PHP, C++, Python, C#, Ruby, Java, Android, Swift und Node.js verfügbar. Wir werden verschiedene Szenarien der MHTML-zu-Bild-Konvertierung betrachten: von Speicher zu Speicher, von einem lokalen Dateisystem zum lokalen Dateisystem usw.
SDK-Beispiele für die Konvertierung von MHTML in Bilder Ein weit verbreiteter Anwendungsfall für Aspose.HTML Cloud SDK-Funktionen ist die Dateiverarbeitung und -konvertierung. Mit dem Cloud SDK können Sie ein MHTML-Dokument anhand seines Namens von einem Speicherort oder aus einer lokalen Datei auf Ihrem Laufwerk abrufen, es in ein bestimmtes Format konvertieren und im Speicher oder auf Ihrem lokalen Laufwerk speichern. Die folgenden Codebeispiele veranschaulichen, wie MHTML mithilfe verfügbarer SDKs für verschiedene Fälle in Bilder konvertiert wird.
Beispiel 1. MHTML in JPG konvertieren JPG ist eines der am häufigsten verwendeten Bildformate. Seine Einzigartigkeit liegt im kontrollierten Qualitätsverlust bei der Komprimierung. Daher wird es häufig zum Speichern und Versenden grafischer Inhalte (Fotos, gescannte Kopien, digitalisierte Bilder) über das Internet verwendet. Sehen wir uns ein Beispiel für die Konvertierung einer lokalen MHTML-Datei in das JPG-Format und das Speichern des Ergebnisses in einem lokalen Dateisystem an. Die Konvertierung erfolgt mit Standardkonvertierungsoptionen.
C# Das folgende Beispiel zeigt die einfachste Möglichkeit, MHTML in JPG mit C# zu konvertieren. Lokales MHTML in JPG konvertiert und im lokalen Pfad gespeichert. Sie können das C# SDK aus dem
GitHub-Repository herunterladen.

Storage API . Copy 1 curl - X POST - v \

5 - H "Authorization:Bearer <JWT_token>" Die Konvertierung von MHTML in JPG erfolgt mit den Standardkonvertierungsoptionen : Die Breite und Höhe des resultierenden JPG-Dokuments entsprechen A4 und alle Ränder haben den Wert Null.
Beispiel 2. Konvertieren Sie MHTML in PNG mit explizit angegebenen Optionen Das PNG-Bildformat wird häufig verwendet, um Bilder über das Netzwerk zu übertragen, Fotos und Grafiken auf Webseiten anzuzeigen und in Cloud-Speichern zu speichern. Eine Konvertierung von MHTML in PNG kann beispielsweise erforderlich sein, wenn Sie eine Webseite in eine PowerPoint-Präsentation einfügen, sie für Ihre Leser in einen Blog einfügen oder sie per E-Mail versenden möchten. Das folgende Beispiel zeigt, wie man MHTML mit explizit angegebenen Optionen in PNG konvertiert und das Ergebnis wieder im lokalen Dateisystem speichert.
C# Das folgende SDK-Beispiel zeigt, wie man MHTML in PNG mit C# konvertiert. MHTML wird aus dem lokalen Dateisystem übernommen, in PNG konvertiert und auf dem lokalen Laufwerk gespeichert. Sie können das C# SDK aus dem

Please take a few steps:
Upload local file to storage using
Storage API . Call REST API to execute conversion (in the example below). Download conversion result back from storage using
Storage API . Copy 1 curl - X POST - v \

Beispiel 3. Konvertieren Sie MHTML in GIF im Cloud-Speicher Mit Aspose.HTML Cloud können Sie eine MHTML-Datei aus Ihrem Cloud-Speicher abrufen und das Konvertierungsergebnis wieder im Cloud-Speicher speichern. Die Konvertierung erfolgt mit Standardkonvertierungsoptionen.
C# Das folgende Beispiel zeigt, wie man MHTML in GIF mit C# konvertiert. Die MHTML-Datei befindet sich im Cloud-Speicher, wird in GIF konvertiert und wieder im Cloud-Speicher gespeichert. Sie können das C# SDK aus dem
GitHub-Repository herunterladen.
