Cara Menambahkan Gambar ke Slide PowerPoint di Java

Gambar dalam Aspose.Slides FOSS disematkan sebagai picture frames, bentuk yang menampung gambar dan dapat diposisikan, diubah ukurannya, serta diberi gaya seperti bentuk lainnya. Data gambar disimpan sekali dalam koleksi prs.getImages() dan direferensikan oleh frame.

Tambahkan Gambar dari File

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);
}

Tanda tangan addPictureFrame:

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

Semua dimensi dalam points (1 point = 1/72 inci). Untuk slide standar 10 x 7,5 inci ruang koordinatnya adalah 720 x 540 points.

Tambahkan Gambar dari Stream

Jika Anda sudah memiliki gambar sebagai InputStream (mis., diunduh dari URL atau dibaca dari basis data):

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);
}

Tambahkan Beberapa Gambar ke Slide yang Berbeda

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);
}

Hitung Gambar dalam Presentasi yang Ada

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)");
}

Koleksi prs.getImages() dibagikan di semua slide: byte gambar yang sama disimpan sekali bahkan jika bingkai gambar muncul di beberapa slide.
