Slides

This guide covers the main OfficeIMO.PowerPoint slide-building workflow. Instead of manually creating SlidePart trees, you work with PowerPointSlide, PowerPointTextBox, PowerPointTable, and related helpers directly.

Start with a title and body region

using OfficeIMO;
using OfficeIMO.PowerPoint;
using OfficeIMO.Drawing;

using var presentation = PowerPointDocument.Create("presentation.pptx");
const double marginCm = 1.5;

var content = presentation.SlideSize.GetContentBox(OfficeLength.Centimeters(marginCm));
var slide = presentation.AddSlide();

slide.AddTitle(
    "Quarterly Results",
    OfficeIMO.OfficeLength.Centimeters(content.Left.ToCentimeters()),
    OfficeIMO.OfficeLength.Centimeters(content.Top.ToCentimeters()),
    OfficeIMO.OfficeLength.Centimeters(content.Width.ToCentimeters()),
    OfficeIMO.OfficeLength.Centimeters(1.4));

slide.AddTextBox(
    "Generated from the reporting pipeline.",
    OfficeIMO.OfficeLength.Centimeters(content.Left.ToCentimeters()),
    OfficeIMO.OfficeLength.Centimeters(content.Top.ToCentimeters() + 1.8),
    OfficeIMO.OfficeLength.Centimeters(content.Width.ToCentimeters()),
    OfficeIMO.OfficeLength.Centimeters(1.0));

Add bullets and formatted text

using OfficeIMO;
using OfficeIMO.PowerPoint;
using A = DocumentFormat.OpenXml.Drawing;

var text = slide.AddTextBox(
    string.Empty,
    OfficeIMO.OfficeLength.Centimeters(content.Left.ToCentimeters()),
    OfficeIMO.OfficeLength.Centimeters(content.Top.ToCentimeters() + 3.0),
    OfficeIMO.OfficeLength.Centimeters(content.Width.ToCentimeters() / 2),
    OfficeIMO.OfficeLength.Centimeters(4.5));

text.SetTextMargins(global::OfficeIMO.OfficeLength.Centimeters(0.3), global::OfficeIMO.OfficeLength.Centimeters(0.2), global::OfficeIMO.OfficeLength.Centimeters(0.3), global::OfficeIMO.OfficeLength.Centimeters(0.2));
text.TextAutoFit = PowerPointTextAutoFit.Normal;

var heading = text.AddParagraph("Highlights", p => {
    p.Alignment = PowerPointTextAlignment.Left;
    p.SpaceAfter = global::OfficeIMO.OfficeLength.Points(6);
});
PowerPointTextStyle.Subtitle.WithColor(OfficeColor.Parse("1F4E79")).Apply(heading);

var line = text.AddParagraph();
line.AddText("Ship ");
line.AddFormattedText("faster", bold: true).SetColor(OfficeColor.Parse("C00000"));
line.AddText(" with cleaner automated decks.");

text.AddBullet("Release completed on schedule");
text.AddBullet("Customer guide updated");
text.AddNumberedItem("Review adoption metrics");
text.AddNumberedItem("Prepare next milestone");
text.ApplyAutoSpacing(lineSpacingMultiplier: 1.15, spaceAfter: global::OfficeIMO.OfficeLength.Points(2));

AddText and AddFormattedText return the run they create, so SetBold, SetColor and the other run setters format only that text. The same setters on a paragraph format every run already in it.

Build tables and charts from data

using OfficeIMO;
using OfficeIMO.PowerPoint;

var rows = new[] {
    new { Product = "Alpha", Q1 = 12, Q2 = 15, Q3 = 18, Q4 = 20 },
    new { Product = "Beta",  Q1 =  9, Q2 = 11, Q3 = 13, Q4 = 14 },
    new { Product = "Gamma", Q1 =  6, Q2 =  9, Q3 = 12, Q4 = 16 }
};

var tableSlide = presentation.AddSlide();
tableSlide.AddTitle("Sales by Product", OfficeIMO.OfficeLength.Centimeters(content.Left.ToCentimeters()), OfficeIMO.OfficeLength.Centimeters(content.Top.ToCentimeters()), OfficeIMO.OfficeLength.Centimeters(content.Width.ToCentimeters()), OfficeIMO.OfficeLength.Centimeters(1.4));

var table = tableSlide.AddTable(
    rows,
    options => {
        options.HeaderCase = HeaderCase.Title;
        options.PinFirst("Product");
    },
    includeHeaders: true,
    left: content.Left,
    top: content.Top + OfficeLength.Centimeters(2.0),
    width: content.Width,
    height: OfficeLength.Centimeters(4.5));

table.SetColumnWidthsEvenly();

var chartSlide = presentation.AddSlide();
chartSlide.AddTitle("Quarterly Performance", OfficeIMO.OfficeLength.Centimeters(content.Left.ToCentimeters()), OfficeIMO.OfficeLength.Centimeters(content.Top.ToCentimeters()), OfficeIMO.OfficeLength.Centimeters(content.Width.ToCentimeters()), OfficeIMO.OfficeLength.Centimeters(1.4));

var chartData = new OfficeChartData(
    rows.Select(r => r.Product),
    new[] {
        new OfficeSeries("Q1", rows.Select(r => (double)r.Q1)),
        new OfficeSeries("Q2", rows.Select(r => (double)r.Q2)),
        new OfficeSeries("Q3", rows.Select(r => (double)r.Q3)),
        new OfficeSeries("Q4", rows.Select(r => (double)r.Q4))
    });

chartSlide.AddChart(OfficeChartType.ColumnClustered, chartData, new OfficeIMO.PowerPoint.PowerPointChartOptions { Left = OfficeIMO.OfficeLength.Centimeters(content.Left.ToCentimeters()), Top = OfficeIMO.OfficeLength.Centimeters(content.Top.ToCentimeters() + 2.0), Width = OfficeIMO.OfficeLength.Centimeters(content.Width.ToCentimeters()), Height = OfficeIMO.OfficeLength.Centimeters(4.8) });
chartSlide.Notes.Text = "Chart and table share the same source data.";

For a native bubble chart, create each series with explicit X, Y, and size values:

var bubbleData = new OfficeChartData(
    new[] { "1", "2", "3" },
    new[] {
        OfficeSeries.CreateBubble(
            "Portfolio",
            xValues: new[] { 1D, 2D, 3D },
            yValues: new[] { 12D, 18D, 15D },
            bubbleSizes: new[] { 9D, 36D, 16D })
    });

chartSlide.AddChart(OfficeChartType.Bubble, bubbleData, new OfficeIMO.PowerPoint.PowerPointChartOptions { Left = OfficeIMO.OfficeLength.Centimeters(content.Left.ToCentimeters()), Top = OfficeIMO.OfficeLength.Centimeters(content.Top.ToCentimeters() + 2.0), Width = OfficeIMO.OfficeLength.Centimeters(content.Width.ToCentimeters()), Height = OfficeIMO.OfficeLength.Centimeters(4.8) });

Bubble sizes must be finite and non-negative, with one size for every X/Y point. The chart remains editable in PowerPoint, and UpdateData(...) refreshes both cached chart values and the embedded workbook.

Manage slide order and reuse

var intro = presentation.AddSlide();
intro.AddTitle("Intro", OfficeIMO.OfficeLength.Centimeters(content.Left.ToCentimeters()), OfficeIMO.OfficeLength.Centimeters(content.Top.ToCentimeters()), OfficeIMO.OfficeLength.Centimeters(content.Width.ToCentimeters()), OfficeIMO.OfficeLength.Centimeters(1.4));

var duplicate = presentation.DuplicateSlide(0);
duplicate.Hidden = true;

using var source = PowerPointDocument.Create("source-deck.pptx");
source.AddSlide().AddTitle("Imported slide", OfficeIMO.OfficeLength.Centimeters(content.Left.ToCentimeters()), OfficeIMO.OfficeLength.Centimeters(content.Top.ToCentimeters()), OfficeIMO.OfficeLength.Centimeters(content.Width.ToCentimeters()), OfficeIMO.OfficeLength.Centimeters(1.4));
source.Save();

presentation.ImportSlide(source, 0, insertAt: 1);
presentation.MoveSlide(2, 0);

Common patterns

• Use AddTitleCm and AddTextBoxCm when you want a readable layout in source code.
• Use SetTextMargins, ApplyTextStyle, and TextAutoFit early so slides stay legible as content grows.
• Build data-heavy slides from objects with AddTable and shared OfficeChartData instead of hard-coded cell text.
• Use Notes.Text for speaker notes and DuplicateSlide, ImportSlide, and MoveSlide when you need reusable deck templates.
