How to add Header, Footer and Text to existing Slides?

[ZubairImran]

Hi @ashahabov ,
Does ShapeCrawler support for adding header and Footer Text also allow Text insertion in existing Slide?. Any hint would be helpful.
In the existing slide can i add text anywhere in the slide?

Thanks
Hyder

Hello @ZubairImran,

Text Shape: Yes, you can add text wherever you want by specifying X and Y positions:

var pres = new Presentation();
var shapeCollection = pres.Slide(1).Shapes;

shapeCollection.AddShape(x: 100, y: 50, width: 100, height: 100);
var addedShape = shapeCollection.Last();
addedShape.Text = "Hello, World!";

Footer: Currently, only slide number content for the footer is supported:

var pres = new Presentation();

pres.Footer.AddSlideNumber();

Header: If I'm correctly understood, Header is the subject of the Notes and Handouts, not the regular slide:

Please correct me if you mentioned another.

Hello @ashahabov ,
First of all thank you for the detailed reply. I understand the text adding in the slide, i will try this hint.

Regarding the footer, wanted to add footer text in each slide , will it be supported in future.?
Regarding the header, my understanding was like word document, where in we can add text exactly opposite position of footer. Is that really supported in PPTX?

Thanks

The issue #945 was created to implement the Footer Text feature. Now it is waiting for a volunteer🙂

Regarding the header, slide doesn't have a built-in concept "Header", only Notes and Handouts (screenshot above). However, you can try to simulate this like below:

        var presStream = new MemoryStream(File.ReadAllBytes(@"c:\temp\header.pptx"));
        var pres = new Presentation(presStream);
        var slideWidth = pres.SlideWidth;

        foreach (var slide in pres.Slides)
        {
            slide.Shapes.AddShape(0, 5, (int)slideWidth, 10);
            var header = slide.Shapes.Last();
            header.TextBox.Text = "My header";
            header.Fill.SetNoFill();
            header.Outline.SetNoOutline();
            header.TextBox.Paragraphs[0].Portions[0].Font!.Color.Update(Color.Black.Hex);
        }
        
        pres.SaveAs(@"c:\temp\output.pptx");
