how to draw a ''dynamic'' image in cell

[Andreas Hirtzel]

Hi,

I'd like to draw an image in a PdfLightTable cell. The only sample I have found shows how to use the BeginCellLayout event and there will be drawn a static image in the cell. What I'd like to achieve is to draw a dynamic image. How can I do this?

Hi Andreas,

Thank you for your interest in Essential PDF.

Drawing dynamic images in table

We can achieve the behavior by choosing the images randomly. Could you please try the below code snippet in your sample and let me know if this helps?

void table_StartCellLayoutHeader(object sender, BeginCellLayoutEventArgs args)
        {
            int rowIndex = args.RowIndex;
            int cellIndex = args.CellIndex;

            Random random = new Random(3);
            string[] imgPath = new string[] { @"..\..\Data\logo.png", @"..\..\Data\logo.gif", @"..\..\Data\logo.jpg" };
            if (rowIndex == 0 && cellIndex == 1)
            {
                PdfGraphics g = args.Graphics;
                PdfImage image = new PdfBitmap(imgPath[random.Next(3)]);
                g.DrawImage( image,new RectangleF(args.Bounds.X+10,args.Bounds.Y,args.Bounds.Width -45,args.Bounds.Height));
            }
        }
