SVG (Scalable Vector Graphics) is an image file format used for rendering two-dimensional images on the web. Comparing with other image file formats, SVG has many advantages such as supporting interactivity and animation, allowing users to search, index, script, and compress/enlarge images without losing quality. Occasionally, you may need to convert PDF files to SVG file format, and this article will demonstrate how to accomplish this task using Spire.PDF for .NET.

In this article, we will explain how to copy an existing chart within the same PowerPoint document or between PowerPoint documents by using Spire.Presentation. Below example called a main method public IChart CreateChart(IChart baseChart, RectangleF rectangle, int nIndex).

There are three Parameters passed in this method:

• baseChart: The source chart.
• rectangle: The area that the chart will be copied to.
• nIndex: The index of the rectangle shape. For example, -1 means append it as the last shape of the slide, 0 means append as the first shape.

Now refer to the following steps:

Copy chart within the same PowerPoint document

Step 1: Instantiate a Presentation object and load the PowerPoint document.

Presentation ppt = new Presentation();
ppt.LoadFromFile("Sample.pptx");

Step 2: Get the chart that is going to be copied.

IChart chart = ppt.Slides[0].Shapes[0] as IChart;

Step 3: Copy the chart from the first slide to the specified location of the second slide within the same document.

ppt.Slides[1].Shapes.CreateChart(chart, new RectangleF(100, 100, 500, 300), 0);

Step 4: Save the document.

ppt.SaveToFile("TestResult.pptx", FileFormat.Pptx2010);

Copy chart between PowerPoint documents

Step 1: Load the first PowerPoint document.

Presentation ppt1 = new Presentation();
ppt1.LoadFromFile("Sample.pptx");

Step 2: Get the chart that is going to be copied.

IChart chart = ppt1.Slides[0].Shapes[0] as IChart;

Step 3: Load the second PowerPoint document.

Presentation ppt2 = new Presentation();
ppt2.LoadFromFile("Dest.pptx");

Step 4: Copy chart from the first document to the specified location of the second document.

ppt2.Slides[0].Shapes.CreateChart(chart, new RectangleF(100, 100, 500, 300), -1);

Step 5: Save the second document.

ppt2.SaveToFile("TestResult2.pptx", FileFormat.Pptx2010);

Spire.XLS enable programmers to insert, modify as well as format comments in Excel. Also, it allows users to fill a comment with solid color, gradient, pattern or a picture to change the look of the comment. This article is going to introduce how to set background image for a comment in Excel using Spire.XLS.

Code Snippet:

Step 1: Initialize an instance of Wordbook and get the first worksheet.

Workbook wb = new Workbook();
Worksheet sheet = wb.Worksheets[0];

Step 2: Fill the comment with a customized background picture.

Image image = Image.FromFile(@"C: \Users\Administrator\Desktop\logo.png");
sheet.Range["C6"].Comment.Fill.CustomPicture(image, "logo.png");

Step 3: Re-set the size of comment box.

sheet.Range["C6"].Comment.Height = image.Height;
sheet.Range["C6"].Comment.Width = image.Width;

Step 4: Save the file.

wb.SaveToFile("PicFillComment.xls", ExcelVersion.Version97to2003);

Output:

Full Code:

using Spire.Xls;
using System.Drawing;
namespace SetPictureFill
{
    class Program
    {

        static void Main(string[] args)
        {

                Image image = Image.FromFile(@"C: \Users\Administrator\Desktop\logo.png");
                sheet.Range["C6"].Comment.Fill.CustomPicture(image, "logo.png");
                sheet.Range["C6"].Comment.Height = image.Height;
                sheet.Range["C6"].Comment.Width = image.Width;

                wb.SaveToFile("PicFill.xls", ExcelVersion.Version97to2003);
