Is custom resolution supported in worksheet to image conversion?

Syncfusion Excel (XlsIO) library is a .NET Excel library used to create, read, and edit Excel documents. Also, converts Excel documents to PDF files.

Currently XlsIO doesn’t have support to convert worksheet into image with custom resolution. However, we can achieve this by changing the resolution of an image before saving it. The following code snippet explains this.


using (ExcelEngine excelEngine = new ExcelEngine())
    IApplication application = excelEngine.Excel;
    IWorkbook workbook = application.Workbooks.Open("../../Data/Template.xlsx");
    IWorksheet worksheet = workbook.Worksheets["Pivot Table"];
    worksheet.UsedRangeIncludesFormatting = false;
    int lastRow = worksheet.UsedRange.LastRow + 1;
    int lastColumn = worksheet.UsedRange.LastColumn + 1;
    Image image = worksheet.ConvertToImage(1, 1, lastRow, lastColumn, ImageType.Bitmap, null);
    //Create a bitmap of specific width and height (500x500)
    Bitmap bitmap = new Bitmap((int)((image.Width * 500) / 96.0f), (int)((image.Height * 500) / 96.0f), PixelFormat.Format32bppPArgb);
    //Set the resolution (500).
    bitmap.SetResolution(500, 500);
    //Get graphics from bitmap with custom size.
    Graphics graphics = Graphics.FromImage(bitmap);
    //Recreate the image from stream using specified width and height.
    graphics.DrawImage(image, new Rectangle(0, 0, bitmap.Width, bitmap.Height));
    //Save the bitmap
    string fileName = "BitmapImg.png";
    bitmap.Save(fileName, ImageFormat.Png);


A complete working sample can be downloaded from CustomResolution.zip.

Take a moment to peruse the documentation, where you can find basic worksheet data manipulation options along with features like Conditional Formatting, worksheet calculations through Formulas, adding Charts in worksheet or workbook, organizing and analyzing data through Tables and Pivot Tables, appending multiple records to worksheet using Template Markers, and most importantly PDF and Image conversions etc. with code examples.
