Picture Frame

A picture frame is a shape that contains an image—it is like a picture in a frame.

You can add an image to a slide through a picture frame. This way, you get to format the image by formatting the picture frame.

Tip

Aspose provides free converters—JPEG to PowerPoint and PNG to PowerPoint—that allow people to create presentations quickly from images.

Create Picture Frame

Create an instance of the Presentation class.
Get a slide’s reference through its index.
Create an IPPImage object by adding an image to the IImagescollection associated with the presentation object that will be used to fill the shape.
Specify the image’s width and height.
Create a PictureFrame based on the image’s width and height through the AddPictureFrame method exposed by the shape object associated with the referenced slide.
Add a picture frame (containing the picture) to the slide.
Write the modified presentation as a PPTX file.

This Java code shows you how to create a picture frame:

// Instantiates the Presentation class that represents a PPTX file
Presentation pres = new Presentation();
try {
    // Gets the first slide
    ISlide sld = pres.getSlides().get_Item(0);
    
    // Instantiates the Image class
    IPPImage imgx = pres.getImages().addImage(new FileInputStream(new File("asp1.jpg")));
    
    // Adds a picture frame with the picture's equivalent height and width
    sld.getShapes().addPictureFrame(ShapeType.Rectangle, 50, 150, imgx.getWidth(), imgx.getHeight(), imgx);
    
    // Write the PPTX file to disk
    pres.save("RectPicFrame.pptx", SaveFormat.Pptx);
} catch (IOException e) {
} finally {
    if (pres != null) pres.dispose();
}

Picture frames allow you to quickly create presentation slides based on images. When you combine picture frame with the save options Aspose.Slides, you can manipulate input/output operations to convert images from one format to another. You may want to see these pages: convert image to JPG; convert JPG to image; convert JPG to PNG, convert PNG to JPG; convert PNG to SVG, convert SVG to PNG.

Create Picture Frame with Relative Scale

By altering an image’s relative scaling, you can create a more complicated picture frame.

Create an instance of the Presentation class.
Get a slide’s reference through its index.
Add an image to the presentation image collection.
Create an IPPImage object by adding an image to the IImagescollection associated with the presentation object that will be used to fill the shape.
Specify the image’s relative width and height in the picture frame.
Write the modified presentation as a PPTX file.

This Java code shows you how to create a picture frame with relative scale:

// Instantiate Presentation class that represents the PPTX
Presentation pres = new Presentation();
try {
    // Get the first slide
    ISlide sld = pres.getSlides().get_Item(0);
    
    // Instantiate the Image class
    IPPImage imgx = pres.getImages().addImage(new FileInputStream(new File("asp1.jpg")));
    
    
    // Add Picture Frame with height and width equivalent of Picture
    IPictureFrame pf = sld.getShapes().addPictureFrame(ShapeType.Rectangle, 50, 150, imgx.getWidth(), imgx.getHeight(), imgx);
    
    // Setting relative scale width and height
    pf.setRelativeScaleHeight(0.8f);
    pf.setRelativeScaleWidth(1.35f);
    
    // Write the PPTX file to disk
    pres.save("RectPicFrame.pptx", SaveFormat.Pptx);
} catch (IOException e) {
} finally {
    if (pres != null) pres.dispose();
}

Extract Image from Picture Frame

You can extract images from PictureFrame objects and save them in PNG, JPG, and other formats. The code example below demonstrates how to extract an image from the document “sample.pptx” and save it in PNG format.

Presentation presentation = new Presentation("sample.pptx");

try {
    ISlide firstSlide = presentation.getSlides().get_Item(0);
    IShape firstShape = firstSlide.getShapes().get_Item(0);

    if (firstShape instanceof IPictureFrame) {
        IPictureFrame pictureFrame = (IPictureFrame) firstShape;
        BufferedImage image = pictureFrame.getPictureFormat().getPicture().getImage().getSystemImage();

        File imageFile = new File("slide_1_shape_1.png");
        ImageIO.write(image, "png", imageFile);
    }
} catch (IOException e) {
} finally {
    presentation.dispose();
}

Get Transparency of Image

Aspose.Slides allows you to get the transparency of an image. This Java code demonstrates the operation:

Presentation presentation = new Presentation(folderPath + "Test.pptx");

var pictureFrame = (IPictureFrame) presentation.getSlides().get_Item(0).getShapes().get_Item(0);
var imageTransform = pictureFrame.getPictureFormat().getPicture().getImageTransform();
for (var effect : imageTransform) {
    if (effect instanceof IAlphaModulateFixed) {
        var alphaModulateFixed = (IAlphaModulateFixed) effect;
        var transparencyValue = 100 - alphaModulateFixed.getAmount();
        System.out.println("Picture transparency: " + transparencyValue);
    }
}

Picture Frame Formatting

Aspose.Slides provides many formatting options that can be applied to a picture frame. Using those options, you can alter a picture frame to make it match specific requirements.

Create an instance of the Presentation class.
Get a slide’s reference through its index.
Create an IPPImage object by adding an image to the IImagescollection associated with the presentation object that will be used to fill the shape.
Specify the image’s width and height.
Create a PictureFrame based on the image’s width and height through the AddPictureFrame method exposed by the IShapes object associated with the referenced slide.
Add the picture frame (containing the picture) to the slide.
Set the picture frame’s line color.
Set the picture frame’s line width.
Rotate the picture frame by giving it either a positive or negative value.
- A positive value rotates the image clockwise.
- A negative value rotates the image anti-clockwise.
Add the picture frame (containing the picture) to the slide.
Write the modified presentation as a PPTX file.

This Java code demonstrates the picture frame formatting process:

// Instantiates the Presentation class that represents the PPTX
Presentation pres = new Presentation();
try {
    // Gets the first slide
    ISlide sld = pres.getSlides().get_Item(0);
    
    // Instantiates the Image class
    IPPImage imgx = pres.getImages().addImage(new FileInputStream(new File("asp1.jpg")));
    
    // Adds Picture Frame with height and width equivalent of Picture
    IPictureFrame pf = sld.getShapes().addPictureFrame(ShapeType.Rectangle, 50, 150, imgx.getWidth(), imgx.getHeight(), imgx);
    
    // Applies some formatting to PictureFrameEx
    pf.getLineFormat().getFillFormat().setFillType(FillType.Solid);
    pf.getLineFormat().getFillFormat().getSolidFillColor().setColor(Color.BLUE);
    pf.getLineFormat().setWidth(20);
    pf.setRotation(45);
    
    // Writes the PPTX file to disk
    pres.save("RectPicFrame.pptx", SaveFormat.Pptx);
} catch (IOException e) {
} finally {
    if (pres != null) pres.dispose();
}

Tip

Aspose recently developed a free Collage Maker. If you ever need to merge JPG/JPEG or PNG images, create grids from photos, you can use this service.

Add Image as Link

To avoid large presentation sizes, you can add images (or videos) through links instead of embedding the files directly into presentations. This Java code shows you how to add an image and video into a placeholder:

Presentation presentation = new Presentation("input.pptx");
try {
    ArrayList<IShape> shapesToRemove = new ArrayList<IShape>();
    int shapesCount = presentation.getSlides().get_Item(0).getShapes().size();

    for (int i = 0; i < shapesCount; i++)
    {
        IShape autoShape = presentation.getSlides().get_Item(0).getShapes().get_Item(i);

        if (autoShape.getPlaceholder() == null)
        {
            continue;
        }

        switch (autoShape.getPlaceholder().getType())
        {
            case PlaceholderType.Picture:
                IPictureFrame pictureFrame = presentation.getSlides().get_Item(0).getShapes().addPictureFrame(ShapeType.Rectangle,
                        autoShape.getX(), autoShape.getY(), autoShape.getWidth(), autoShape.getHeight(), null);

                pictureFrame.getPictureFormat().getPicture().setLinkPathLong(
                        "https://upload.wikimedia.org/wikipedia/commons/3/3a/I.M_at_Old_School_Public_Broadcasting_in_October_2016_02.jpg");

                shapesToRemove.add(autoShape);
                break;

            case PlaceholderType.Media:
                IVideoFrame videoFrame = presentation.getSlides().get_Item(0).getShapes().addVideoFrame(
                        autoShape.getX(), autoShape.getY(), autoShape.getWidth(), autoShape.getHeight(), "");

                videoFrame.getPictureFormat().getPicture().setLinkPathLong(
                        "https://upload.wikimedia.org/wikipedia/commons/3/3a/I.M_at_Old_School_Public_Broadcasting_in_October_2016_02.jpg");

                videoFrame.setLinkPathLong("https://youtu.be/t_1LYZ102RA");

                shapesToRemove.add(autoShape);
                break;
        }
    }

    for (IShape shape : shapesToRemove)
    {
        presentation.getSlides().get_Item(0).getShapes().remove(shape);
    }

    presentation.save("output.pptx", SaveFormat.Pptx);
} finally {
    if (presentation != null) presentation.dispose();
}

Crop Image

This Java code shows you how to crop an existing image on a slide:

Presentation pres = new Presentation();
try {
    byte[] imageBytes = Files.readAllBytes(Paths.get(imagePath));
    // Creates new image object
    IPPImage newImage = pres.getImages().addImage(imageBytes);

    // Adds a PictureFrame to a Slide
    IPictureFrame picFrame = pres.getSlides().get_Item(0).getShapes().addPictureFrame(
            ShapeType.Rectangle, 100, 100, 420, 250, newImage);

    // Crops the image (percentage values)
    picFrame.getPictureFormat().setCropLeft(23.6f);
    picFrame.getPictureFormat().setCropRight(21.5f);
    picFrame.getPictureFormat().setCropTop(3);
    picFrame.getPictureFormat().setCropBottom(31);

    // Saves the result
    pres.save(outPptxFile, SaveFormat.Pptx);
} catch (IOException e) {
} finally {
    if (pres != null) pres.dispose();
}

Delete Cropped Areas of Picture

If you want to delete the cropped areas of an image contained in a frame, you can use the deletePictureCroppedAreas() method. This method returns the cropped image or the origin image if cropping is unnecessary.

This Java code demonstrates the operation:

Presentation presentation = new Presentation("PictureFrameCrop.pptx");
try {
    ISlide slide = presentation.getSlides().get_Item(0);

    // Gets the PictureFrame from the first slide
    IPictureFrame picFrame = (IPictureFrame)slide.getShapes().get_Item(0);

    // Deletes cropped areas of the PictureFrame image and returns the cropped image
    IPPImage croppedImage = picFrame.getPictureFormat().deletePictureCroppedAreas();

    // Saves the result
    presentation.save("PictureFrameDeleteCroppedAreas.pptx", SaveFormat.Pptx);
} finally {
    if (presentation != null) presentation.dispose();
}

NOTE

The deletePictureCroppedAreas() method adds the cropped image to the presentation image collection. If the image is only used in the processed PictureFrame, this setup can reduce the presentation size. Otherwise, the number of images in the resulting presentation will increase.

This method converts WMF/EMF metafiles to raster PNG image in the cropping operation.

Lock Aspect Ratio

If you want a shape containing an image to retain its aspect ratio even after you change the image dimensions, you can use the setAspectRatioLocked method to set the Lock Aspect Ratio setting.

This Java code shows you how to lock a shape’s aspect ratio:

Presentation pres = new Presentation("pres.pptx");
try {
    ILayoutSlide layout = pres.getLayoutSlides().getByType(SlideLayoutType.Custom);
    ISlide emptySlide = pres.getSlides().addEmptySlide(layout);
    byte[] imageBytes = Files.readAllBytes(Paths.get("image.png"));
    IPPImage presImage = pres.getImages().addImage(imageBytes);

    IPictureFrame pictureFrame = emptySlide.getShapes().addPictureFrame(
            ShapeType.Rectangle, 50, 150, presImage.getWidth(), presImage.getHeight(), presImage);

    // set shape to have to preserve aspect ratio on resizing
    pictureFrame.getPictureFrameLock().setAspectRatioLocked(true);
} catch(IOException e) {
} finally {
    if (pres != null) pres.dispose();
}

NOTE

This Lock Aspect Ratio setting preserves only the aspect ratio of the shape and not the image it contains.

Use StretchOff Property

Using the StretchOffsetLeft, StretchOffsetTop, StretchOffsetRight and StretchOffsetBottom properties from the IPictureFillFormat interface and PictureFillFormat class, you can specify a fill rectangle.

When stretching is specified for an image, a source rectangle is scaled to fit the specified fill rectangle. Each edge of the fill rectangle is defined by a percentage offset from the corresponding edge of the shape’s bounding box. A positive percentage specifies an inset while a negative percentage specifies an outset.

Create an instance of the Presentation class.
Get a slide’s reference through its index.
Add a rectangle AutoShape.
Create an image.
Set the shape’s fill type.
Set the shape’s picture fill mode.
Add a set image to fill the shape.
Specify image offsets from the corresponding edge of the shape’s bounding box
Write the modified presentation as a PPTX file.

This Java code demonstrates a process in which a StretchOff property is used:

// Instantiates the Prseetation class that represents a PPTX file
Presentation pres = new Presentation();
try {
    // Gets the first slide
    ISlide slide = pres.getSlides().get_Item(0);

    // Instantiates the ImageEx class
    BufferedImage img = ImageIO.read(new File("aspose-logo.jpg"));
    IPPImage imgEx = pres.getImages().addImage(img);

    // Adds an AutoShape set to Rectangle
    IAutoShape aShape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 300, 300);

    // Sets the shape's fill type
    aShape.getFillFormat().setFillType(FillType.Picture);

    // Sets the shape's picture fill mode
    aShape.getFillFormat().getPictureFillFormat().setPictureFillMode(PictureFillMode.Stretch);

    // Sets the image to fill the shape
    aShape.getFillFormat().getPictureFillFormat().getPicture().setImage(imgEx);

    // Specifies the image offsets from the corresponding edge of the shape's bounding box
    aShape.getFillFormat().getPictureFillFormat().setStretchOffsetLeft(25);
    aShape.getFillFormat().getPictureFillFormat().setStretchOffsetRight(25);
    aShape.getFillFormat().getPictureFillFormat().setStretchOffsetTop(-20);
    aShape.getFillFormat().getPictureFillFormat().setStretchOffsetBottom(-10);
    
    //Writes the PPTX file to disk
    pres.save("StretchOffsetLeftForPictureFrame_out.pptx", SaveFormat.Pptx);
} catch (IOException e) {
} finally {
    if (pres != null) pres.dispose();
}
