Kako dodati slike u PowerPoint slajdove u Javi

Slike u Aspose.Slides FOSS su ugrađene kao picture frames, oblici koji drže sliku i mogu se pozicionirati, menjati veličinu i stilizovati kao bilo koji drugi oblik. Podaci o slici se čuvaju jednom u kolekciji prs.getImages() i na njih se referiše kroz okvir.

Dodajte sliku iz datoteke 

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IPPImage;
import org.aspose.slides.foss.IPictureFrame;
import org.aspose.slides.foss.ILayoutSlide;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.export.SaveFormat;
import java.nio.file.Files;
import java.nio.file.Paths;

try (Presentation prs = new Presentation()) {
    ISlide slide = prs.getSlides().get(0);

    // Load image into the presentation's image collection
    byte[] imageData = Files.readAllBytes(Paths.get("photo.jpg"));
    IPPImage img = prs.getImages().addImage(imageData);

    // Add a picture frame at (x=50, y=50, width=400, height=300) in points
    IPictureFrame frame = slide.getShapes().addPictureFrame(
        ShapeType.RECTANGLE,
        50, 50, 400, 300,
        img
    );

    prs.save("with-image.pptx", SaveFormat.PPTX);
}

Potpis addPictureFrame:

addPictureFrame(shapeType, x, y, width, height, image) -> IPictureFrame

Sve dimenzije su u tačkama (1 tačka = 1/72 inča). Za standardni slajd od 10 x 7,5 inča prostor koordinata je 720 x 540 tačaka.

Dodajte sliku iz toka

Ako već imate sliku kao InputStream (npr., preuzetu sa URL‑a ili pročitanu iz baze podataka):

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IPPImage;
import org.aspose.slides.foss.IPictureFrame;
import org.aspose.slides.foss.ILayoutSlide;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.export.SaveFormat;
import java.io.FileInputStream;

try (Presentation prs = new Presentation();
     FileInputStream fis = new FileInputStream("logo.png")) {
    IPPImage img = prs.getImages().addImage(fis);

    prs.getSlides().get(0).getShapes().addPictureFrame(
        ShapeType.RECTANGLE,
        200, 100, 300, 200,
        img
    );
    prs.save("logo-slide.pptx", SaveFormat.PPTX);
}

Dodajte više slika na različite slajdove 

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IPPImage;
import org.aspose.slides.foss.IPictureFrame;
import org.aspose.slides.foss.ILayoutSlide;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.export.SaveFormat;
import java.nio.file.Files;
import java.nio.file.Paths;

String[] imageFiles = {"slide1.jpg", "slide2.jpg", "slide3.jpg"};

try (Presentation prs = new Presentation()) {
    ILayoutSlide layout = prs.getSlides().get(0).getLayoutSlide();

    // Ensure enough slides exist
    while (prs.getSlides().size() < imageFiles.length) {
        prs.getSlides().addEmptySlide(layout);
    }

    for (int i = 0; i < imageFiles.length; i++) {
        if (!Files.exists(Paths.get(imageFiles[i]))) continue;
        byte[] data = Files.readAllBytes(Paths.get(imageFiles[i]));
        IPPImage img = prs.getImages().addImage(data);
        prs.getSlides().get(i).getShapes().addPictureFrame(
            ShapeType.RECTANGLE, 0, 0, 720, 540, img
        );
    }

    prs.save("multi-image.pptx", SaveFormat.PPTX);
}

Prebrojite slike u postojećoj prezentaciji 

import org.aspose.slides.foss.Presentation;
import org.aspose.slides.foss.ISlide;
import org.aspose.slides.foss.IPPImage;
import org.aspose.slides.foss.IPictureFrame;
import org.aspose.slides.foss.ILayoutSlide;
import org.aspose.slides.foss.ShapeType;
import org.aspose.slides.foss.export.SaveFormat;

try (Presentation prs = new Presentation("with-image.pptx")) {
    System.out.println("Presentation contains "
        + prs.getImages().size() + " image(s)");
}

prs.getImages() kolekcija se deli kroz sve slajdove: isti bajtovi slike se čuvaju jednom čak i ako se okvir slike pojavljuje na više slajdova.
