Hi,

Pls see attached pptx:
sample1.zip (133.4 KB)

The code I ran:

using Aspose.Slides;
using Aspose.Slides.Export;
using Aspose.Slides.Animation;
using Aspose.Slides.Charts;
using Aspose.Slides.SmartArt;
using Aspose.Slides.Ink;
using System.Drawing;
using System.Drawing.Imaging;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.Collections;
using System.Xml;
using System.Threading;
using System.Reflection;
using System.IO;
using System.Drawing.Text;
class Program
{
    static void Main(string[] args)
    {
        try
        {
            // Apply Aspose.Slides license
            License license = new License();
            license.SetLicense("Aspose.Total.lic"); // Make sure this file is in your application's directory
            Console.WriteLine("\nLicense applied successfully");

            // Load the presentation
            using (Presentation presentation = new Presentation("sample1.pptx"))
            {
                Console.WriteLine("Number of slides in the presentation: " + presentation.Slides.Count);
                
                // Create output directory if it doesn't exist
                string outputDir = "slide_images";
                if (!Directory.Exists(outputDir))
                {
                    Directory.CreateDirectory(outputDir);
                }
                
                // Convert each slide to image
                for (int i = 0; i < presentation.Slides.Count; i++)
                {
                    ISlide slide = presentation.Slides[i];
                    
                    // Create a full scale image
                    using (IImage image = slide.GetImage(1.0f, 1.0f))
                    {
                        string fileName = Path.Combine(outputDir, $"slide_{i + 1}.png");
                        image.Save(fileName, Aspose.Slides.ImageFormat.Png);
                        Console.WriteLine($"Saved slide {i + 1} as {fileName}");
                    }
                }
                
                Console.WriteLine($"\nAll slides exported to images in '{outputDir}' folder");
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine($"An error occurred: {ex.Message}");
        }
    }
}

I used Aspose 25.9 and net9.0.

The output image is attached.
slide_1.png (43.4 KB)

I see text wrapping issue on the Y-axis. of the graph In the original PPT, the label “100,000 persons”*wraps to the next line, whereas in image generated by the above code, “100,000” stays on the first line and “persons” goes in second line.

Kindly help resolve this wrapping issue.

Thanks,
@bhav
