Hi,

Can anyone please give the Java code to remove background image from ppt and pptx files.

This is very urgent , any help is appreciated.

I am using the following java code to insert an image:

Presentation pres = new Presentation(new FileInputStream(new File("D:/MasterBackground.ppt")));

int number = pres.getFirstSlideNumber() + pres.getSlides().getLastSlidePosition() - 1;


//Accessing a slide using its slide position



for(int i=0;i<number;i++){

Slide slide = pres.getSlides().get(i);



//Slide slide = pres.getSlideByPosition(1);

//Disable following master background settings

slide.setFollowMasterBackground(false);

//Setting the fill type of the background to picture

slide.getBackground().getFillFormat().setType(FillType.PICTURE);

//Creating a stream to hold the image file

InputStream iStream = new BufferedInputStream(new FileInputStream("D:/Winter.jpeg"));

//Creating a picture object that will be used as a slide background

Picture pic = new com.aspose.slides.Picture(pres,iStream);

//Adding the picture object to pictures collection of the presentation

//After the picture object is added, the picture is given a unique picture Id

int picId = pres.getPictures().add(pic);

//Setting the picture Id of the slide background to the Id of the picture object

slide.getBackground().getFillFormat().setPictureId(picId);


}
//Writing the presentation as a PPT file

pres.write(new FileOutputStream(new File("D:/MasterBackground.ppt")));

Hello Sam,

To remove background image on ppt slide you just need to set NO_FILL fill type:

slide.setFollowMasterBackground(false);
slide.getBackground().getFillFormat().setType(FillType.NO_FILL);

On pptx slides access to a slide background already implemented but not released yet. I will check if it’s possible to provide new version for you today or tomorrow.

Hello Sam,

There is new version of Aspose.Slides for Java with access to a slide background.

For example to remove background image (and also disable all fill styles of background) on the first slide in a presentation you should use this code:

SlideEx slide = presentation.getSlides().get(0);

BackgroundEx bkg = slide.getBackground();
bkg.setType(BackgroundTypeEx.OWN_BACKGROUND);
bkg.getFillFormat().setFillType(FillTypeEx.NOFILL);

That is example how to set background image:

BackgroundEx bkg = pres1.getSlides().get(0).getBackground();
bkg.setType(BackgroundTypeEx.OWN_BACKGROUND);
bkg.getFillFormat().setFillType(FillTypeEx.PICTURE);
bkg.getFillFormat().getPictureFillFormat().setPictureFillMode(PictureFillModeEx.TILE);

FileSeekableStream fss = new FileSeekableStream(“picture_1.jpg”);
RenderedImage image = JAI.create(“stream”, fss);
ImageEx pic = pres1.getImages().addImage(image);
bkg.getFillFormat().getPictureFillFormat().getPicture().setImage(pic);

Hi Alexey Zhilin,

Are there any extra Jar libraries that needs to be loaded for this code to work apart from aspose slides?

Please help !!

Hello,

JAI and JAI-ImageIO is standard requirement for Aspose.Slides for Java. Also I’d suggest to have Aspose.Metafiles in case presentations have any wmf/emf metafiles inside.

Example I provided has these additional imports:
import javax.media.jai.JAI;
import com.sun.media.jai.codec.FileSeekableStream;

From JAI you need only these jars:
jai_codec.jar
jai_core.jar
jai-imageio.jar
Other JAI files and jars are not necessary.

Hi Alexey Zhilin,

Thanks for you update , as per your code

BackgroundEx bkg = pres1.getSlides().get(0).getBackground();

there is no method getBackground available for aspose-slides-2.0.0.4.jar version

how did you declare your pres1,

Is it like below mentioned way ?

PresentationEx pres1 = new Presentation(new FileInputStream(new File("D:/MasterBackground.pptx"))); or any other way ?

Please help !!
