Picture SpreadsheetGear API Sample

// Create a new workbook and get a reference to the active worksheet, cells and 
// window info.
SpreadsheetGear.IWorkbook workbook = SpreadsheetGear.Factory.GetWorkbook();
SpreadsheetGear.IWorksheet worksheet = workbook.ActiveWorksheet;
SpreadsheetGear.IRange cells = worksheet.Cells;
SpreadsheetGear.IWorksheetWindowInfo windowInfo = worksheet.WindowInfo;

// Set up the image file name.
string filename = "SG-Picture.png";

// Get the width and height of the picture in pixels and convert to
// points for use in the call to AddPicture.  This step is only
// necessary if the actual picture size is to be used and that size
// is unknown.  Another option is to calculate the width and height 
// in row and column coordinates in the same manner as the left 
// and top are calculated in the code below.
double width;
double height;
System.Drawing.Image image = System.Drawing.Image.FromFile(filename);
using (image)
{
    width = image.Width * 72.0 / image.HorizontalResolution;
    height = image.Height * 72.0 / image.VerticalResolution;
}

// Calculate the left and top coordinates of the picture by converting 
// row and column coordinates to points.  Use fractional values to 
// get coordinates anywhere in between row and column boundaries.
double left = windowInfo.ColumnToPoints(0.25);
double top = windowInfo.RowToPoints(1.5);

// Add the picture from the file's bytes and use the calculated bounds.
byte[] imageBytes = System.IO.File.ReadAllBytes(filename);
SpreadsheetGear.Shapes.IShape shape =
    worksheet.Shapes.AddPicture(imageBytes, left, top, width, height);

// Remove the border around the picture shape.
shape.Line.Visible = false;

// Select the picture.
shape.Select(true);
