OLE Objekt

Tento článek ukazuje, jak vložit soubor jako OLE objekt a aktualizovat jeho data pomocí Aspose.Slides for Java.

Přidat OLE objekt

Vložit soubor PDF do prezentace.

static void addOleObject() throws IOException {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        byte[] pdfData = Files.readAllBytes(Paths.get("doc.pdf"));
        IOleEmbeddedDataInfo dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
        IOleObjectFrame oleFrame = slide.getShapes().addOleObjectFrame(20, 20, 50, 50, dataInfo);
    } finally {
        presentation.dispose();
    }
}

Přístup k OLE objektu

Získat první OLE objekt na snímku.

static void accessOleObject() throws IOException {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        byte[] pdfData = Files.readAllBytes(Paths.get("doc.pdf"));
        IOleEmbeddedDataInfo dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
        IOleObjectFrame oleFrame = slide.getShapes().addOleObjectFrame(20, 20, 50, 50, dataInfo);

        IOleObjectFrame firstOleFrame = null;
        for (IShape shape : slide.getShapes()) {
            if (shape instanceof IOleObjectFrame) {
                firstOleFrame = (IOleObjectFrame) shape;
                break;
            }
        }
    } finally {
        presentation.dispose();
    }
}

Odstranit OLE objekt

Smazat vložený OLE objekt ze snímku.

static void removeOleObject() throws IOException {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        byte[] pdfData = Files.readAllBytes(Paths.get("doc.pdf"));
        IOleEmbeddedDataInfo dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
        IOleObjectFrame oleFrame = slide.getShapes().addOleObjectFrame(20, 20, 50, 50, dataInfo);
        
        slide.getShapes().remove(oleFrame);
    } finally {
        presentation.dispose();
    }
}

Aktualizovat data OLE objektu

Nahradit data vložená v existujícím OLE objektu.

static void updateOleObjectData() throws IOException {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);
        
        byte[] pdfData = Files.readAllBytes(Paths.get("doc.pdf"));
        OleEmbeddedDataInfo dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
        IOleObjectFrame oleFrame = slide.getShapes().addOleObjectFrame(20, 20, 50, 50, dataInfo);

        byte[] newData = Files.readAllBytes(Paths.get("Picture.png"));
        OleEmbeddedDataInfo newDataInfo = new OleEmbeddedDataInfo(newData, "png");
        oleFrame.setEmbeddedData(newDataInfo);
    } finally {
        presentation.dispose();
    }
}
