Missing SVG text in exported PPTX

Aspose.Slides Product Family
1

Hi There,

I have a problem to add a SVG string with one text element to the Aspose.Slides GroupShapes.

The exported PPTX file is absolutely empty - it shows nothing…

...
var svgData = "<svg height='100' width='200'><text x='0' y='15' fill='red'>I love SVG!</text></svg>";
ISvgImage svgImage = new SvgImage(svgData);
IGroupShape groupShape = Slide.gSlide.Shapes.AddGroupShape(svgImage, 0, 0, 200, 100);
...

Can you help me ?

Thanks,
Marius W.

@Dejab,

I have observed your requirement and regret to share that what you are doing is not possible. The group shape is only a cluster or group of shapes. GroupShape it self is not a normal shape. You need to access a particular shape inside group shape collection and then add SVG to that. This is neither an issue nor a limitation of API.

Thanks for your answer.

Can you give me an example to add something like that SVG to powerpoint ?

<svg height='100' width='200'><text x='0' y='15' fill='red'>I love SVG!</text></svg>

Thanks,

@mudassir.fayyaz,

Thanks for you answer.

Okey i see there is no way to add text from a svg image to the slide with aspose.slides.

In Powerpoint ( Version 16.37 ) there is a way to convert an imported svg image to a group shape - with text ! ( Right click on the svg and click “convert to shapes…” ):
pptx.png (100.6 KB)

My example svg with multiple forms and texts in it:
test.svg.zip (21.2 KB)

Is there a similar function in Aspose.Slides to convert an imported svg to group shapes with texts ?

Thanks,

@Dejab,

In the example link that I have shared, its evident that SVG content is added as string. If you have file as SVG, you can read the file and convert to string. If you have a SVG string, you can directly add that in presentation Image collection.

There is no such option to import an SVG in group shape. As mentioned earlier, group shape is only a logical collection of shapes grouped together. This is neither a limitation nor an issue.

When i use that way to add svg to the slide and then convert that image to a group Shape like in your documentation:

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_PresentationSaving();

using (Presentation pres = new Presentation(dataDir+ "image.pptx"))
{
    PictureFrame pFrame = pres.Slides[0].Shapes[0] as PictureFrame;
    ISvgImage svgImage = pFrame.PictureFormat.Picture.Image.SvgImage;
    if (svgImage != null)
    {
        // Convert svg image into group of shapes
        IGroupShape groupShape = pres.Slides[0].Shapes.AddGroupShape(svgImage, pFrame.Frame.X, pFrame.Frame.Y,
            pFrame.Frame.Width, pFrame.Frame.Height);
        // remove source svg image from presentation
        pres.Slides[0].Shapes.Remove(pFrame);
    }

    pres.Save(dataDir + "image_group.pptx", SaveFormat.Pptx);
}

All texts are gone and missing that exists in the svg image… that’s my problem !
Powerpoint not remove texts by convert it to shapes like my example from above.

Here is a picture of the missing texts:

Hope you can help me or create a ticket for it ?

@mudassir.fayyaz,

My Code:

        string svgPath = "germany.svg";

        string svgContent = File.ReadAllText(svgPath);

        svgContent = Regex.Replace(svgContent, @"stroke-width='.*?'", "");

        ISvgImage svgImage = new SvgImage(svgContent);

        Presentation pres = new Presentation();

        IPPImage ppImage = pres.Images.AddImage(svgImage);

        IPictureFrame pFrame = pres.Slides[0].Shapes.AddPictureFrame(ShapeType.Rectangle, 0, 0, ppImage.Width, ppImage.Height, ppImage);

        IGroupShape groupShape = pres.Slides[0].Shapes.AddGroupShape(svgImage, pFrame.Frame.X, pFrame.Frame.Y, pFrame.Frame.Width, pFrame.Frame.Height);

        pres.Slides[0].Shapes.Remove(pFrame);

        pres.Save("export.pptx", SaveFormat.Pptx);

My SVG File:
