Contenido del texto

Ya sea que estés creando una nueva presentación o editando una existente, las herramientas de gestión de texto te brindan control total sobre la colocación y el formato del texto, permitiéndote diseñar diapositivas que transmitan tu mensaje de manera clara y profesional.

using IronPPT;
using IronPPT.Models;

// Create a new PowerPoint presentation
var document = new PresentationDocument();

// Ensure there is at least one slide to work with
if (document.Slides.Count == 0)
{
    document.Slides.Add(new Slide());
}

// Add text to the first slide
var text = document.Slides[0].AddText("Hello");

// Append text to the existing text on the slide
text.Content += " There!";

// Check if there is any text element to remove from the first slide
if (document.Slides[0].Texts.Count > 0)

Establecer estilo

Estilizar el texto te permite personalizar su apariencia visual definiendo atributos como el tamaño de fuente, color, estilo, tachado y subrayado. Aplicar estos estilos mejora la presentación del texto y mejora el aspecto general del documento.

:path=/static-assets/ppt/content-code-examples/tutorials/slide-element-text-style.cs
using IronPPT;
using IronPPT.Models; // Ensure the library is available

// Create a new presentation document
var document = new PresentationDocument();

// Define and customize the text style
var textStyle = new TextStyle
{
    IsBold = true,                      // Text is bold
    IsItalic = true,                    // Text is italic
    Color = Color.Blue,                 // Text color is blue
    Strike = StrikeValue.SingleStrike,  // Text is single struck-off
    Outline = true,                     // Text has an outline
    NoProof = true,                     // Disables proofing for the text
    Spacing = 10.0,                     // Text spacing is set to 10
    Underline = new Underline 
    {
        LineValue = UnderlineValues.Single,   // Single underline
        Color = Color.Red                     // Underline color is red
    },
    Languages = "en-US",               // Text language is set to U.S. English
    SpecVanish = false,                // Text does not vanish when special formatting is applied
};

// Create text content and apply the defined style
var text = new Text("Hello World");   // Instantiate text with a string
text.TextStyle = textStyle;           // Apply the defined style to the text

// Add a new slide if none exist
if (document.Slides.Count == 0)
{
    document.Slides.Add(new Slide());   // Add a new slide to the document
}

// Add the styled text to the first slide
document.Slides[0].AddText(text);      // Add the newly created text object to the first slide

// Save the presentation document to a file
document.Save("textStyle.pptx");        // Save the document with the filename "textStyle.pptx"
