Find and Replace images in Slides

Hi,


I’m trying to find and replace specific images. How can I do this. I have already manage to do this in aspose word by doing the following

NodeCollection shapeCollection = document.getChildNodes(NodeType.SHAPE, true);

shapeCollection.forEach(shape -> {

if (shape.isImage()) {

if (shape.getName().equals(“picture name”)) {
try {
shape.getImageData().setImageBytes(imageByte);

} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
});

I cant do the same in aspose slides. Please help. Thank You

Hi,


So is there any other way I can find a image and replace it using Aspose Slide?? Getting all images as a collection and replacing works.
presentation.getImages().forEach(image->{
image.replaceImage(newImageData);
});

But above code will replace all images in slides cause there is no way of identifying each images.

Hi Ravindu,


I have observed your comments and like to request you to please try using following sample code on your end to serve the purpose, and then share your kind feedback with us.

Presentation pres = new Presentation(“D:\replacepic.pptx”);

for (ISlide slide : pres.getSlides())
{
for (IShape shape : slide.getShapes())
{
if (shape instanceof PictureFrame)
{
IPictureFrame pf = (IPictureFrame) shape;
if (pf.getAlternativeText().compareTo(“test”) == 0)
{
IPPImage imgx = null;
try
{
imgx = pres.getImages().addImage(new FileInputStream(new File(“C:\test.JPG”)));
IPPImage oldImage = pf.getPictureFormat().getPicture().getImage();
oldImage.replaceImage(imgx);
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
}
}
}
//Write the PPTX file to disk
pres.save(“D:\test.pptx”, SaveFormat.Pptx);

A picture is contained within a picture frame, which is basically a shape. A shape could be distinguished by the AlternativeText of that shape, as explained in this documentation article. Then the image is being replaced as in the code sample above. I have also attached the sample presentation for your kind reference.

I hope this will be helpful. Please share if I may help you further in this regard.

Hi,

I was able to do this by this,

presentation.getSlides().forEach(slide -> {
slide.getShapes().forEach(shape -> {

IPPImage s = presentation.getImages().addImage(b);
if (shape.getName().equals(documentTagDTO.getName())) {
if (shape instanceof PictureFrame) {
com.aspose.slides.PictureFrame picFrame = (PictureFrame) shape;
picFrame.getPictureFormat().getPicture().setImage(s);
}
}

shape.getFillFormat().getPictureFillFormat().setPictureFillMode(PictureFillMode.Tile);
IPPImage value = presentation.getImages().addImage(b);
shape.getFillFormat().getPictureFillFormat().getPicture().setImage(value);
});
});

Thanks for your help…
