c# how insert - Adding images into Excel using EPPlus





3 Answers

This is one solution that you can apply in C#.

private void AddImage(ExcelWorksheet oSheet, int rowIndex, int colIndex, string imagePath)
{
    Bitmap image = new Bitmap(imagePath);
    ExcelPicture excelImage = null;
    if (image != null)
    {
        excelImage = oSheet.Drawings.AddPicture("Debopam Pal", image);
        excelImage.From.Column = colIndex;
        excelImage.From.Row = rowIndex;
        excelImage.SetSize(100, 100);
        // 2x2 px space for better alignment
        excelImage.From.ColumnOff = Pixel2MTU(2);
        excelImage.From.RowOff = Pixel2MTU(2);
    }
}

public int Pixel2MTU(int pixels)
{
    int mtus = pixels * 9525;
    return mtus;
}
cell read datatable

I am trying to add the same image multiple times into an excel file using EPPlus. I am using the following code to do so:

Image logo = Image.FromFile(path);
ExcelPackage package = new ExcelPackage(info);
var ws = package.Workbook.Worksheets.Add("Test Page");
for(int a = 0; a < 5; a++)
{
    ws.Row(a*5).Height = 39.00D;
    var picture = ws.Drawings.AddPicture(a.ToString(), logo);
    picture.SetPosition(a*5, 0, 2, 0);
}

Everything works perfectly and all the images are correctly added but they are stretched downwards. Here is what one of the pictures should look like:

But it looks like this in excel:

I have to resize each row of the start of each picture but I dont think that would be affecting it. Would there be a way to add the pictures/do what I am trying to do or would I have to copy-paste the images in manually? (I am using the picture as an example)

Thanks.




Add the following right before you save the document:

foreach (ExcelPicture drawing in ws.Drawings)
   drawing.SetSize(100);



when you are passing say example 39 as pixel it will take it as point insted of pixel internally, so you think that you are going to set row's height to 39 pixel but actually it is setting row's height to 39 point. so according to following formula your row height will became 52 pixel.

If you want to set row's height to 39px, mean you have to pass 29.25 Point(according to formula) insted of 39.

points = pixels * 72 / 96

Try this one.
