Hello,

What is the programming interface (COM, OCX, API, .Net, etc.) that you are using?
What is the programming language that you are using?

However, if you are using COM
programming interface with VB, you can draw text on the image by using the DrawText method (ILEADRasterFXD) as shown below follows:

+---------------------------------+
Dim LeadRasIO As New LEADRasterIO
Dim RasterFxd As New LEADRasterFXD
...
LeadRasIO.Load LEADRasterView2.Raster, "d:\lead14\dist\images\ulay1.bmp", 0, 0, 1
'Set the text properties
RasterFxd.TextTop = 50
RasterFxd.TextLeft = 50
RasterFxd.TextWidth = LEADRasterView1.DstWidth - 50
RasterFxd.TextHeight = LEADRasterView1.DstHeight - 50
RasterFxd.TextAlign = FXD_TEXTALIGN_HCENTER_VCENTER
RasterFxd.TextAngle = 450   '45 degrees
'Text highlight color and style
RasterFxd.TextHiliteColor = RGB(0, 0, 0)
RasterFxd.TextStyle = FXD_TEXTSTYLE_DROPSHADOW
'Draw the text
RasterFxd.DrawText LEADRasterView1.Raster, 0, "LEADTOOLS", LEADRasterView1.Raster.Bitmap
...
+---------------------------------+

Hi Maen,

How would we go about doing something like that with .NET and LEADTools Document Imaging v14?

Hi Mike,

You can draw text (string) using LEADTOOLS .Net SDK by using the following code:
+-----------------------------------------+
using System.Drawing;
using System.Drawing.Drawing2D;
...
private void button2_Click(object sender, System.EventArgs e)
{
RasterImageGdiPlusGraphicsContainer container = rasterImageViewer1.Image.CreateGdiPlusGraphics();
container.Graphics.SmoothingMode = SmoothingMode.HighQuality;
Brush br = new LinearGradientBrush(Point.Empty, new Point(200, 200), Color.Red, Color.Yellow);
Font font1 = new Font(FontFamily.GenericSansSerif,12);
PointF point1 = new PointF(100,100);

container.Graphics.DrawString("LEADTOOLS",font1,br,point1);
rasterImageViewer1.Refresh();
}
+-----------------------------------------+

Thanks,
