Adding a footer before printing

I have an jpg image 400 x 400 and printing it on A4 paper i would like to add a footer note at the bottom of the page. But i can only get the text to be in the bounds of the image. I have attached the code.

I'm using version 14.5 of Lead tools for .Net

Re: Adding a footer before printing

private void AddPageFooter(IRasterImage image, AnnContainer container)
{
container.Bounds = new AnnRectangle(0, 0,
printDocument.DefaultPageSettings.PrintableArea.Width,
printDocument.DefaultPageSettings.PrintableArea.Height, AnnUnit.Millimeter);
container.UnitConverter = new AnnUnitConverter(image.ImageWidth, image.ImageHeight);

container.Name = "Container";
container.Visible = true;

AnnTextObject text = new AnnTextObject();

text.Text = string.Format("Document - {0} Revision {1} Date {2}", "TestDoc");
text.Pen = new AnnPen(Color.Red,new AnnLength(4)) ;
text.Brush = null;
text.EdgeMargin = AnnLength.Empty;
text.Alignment = StringAlignment.Center;
text.LineAlignment = StringAlignment.Center;
text.TextColor = Color.Black;
text.Font = new AnnFont(InvuRenderer.Instance.FontName, new AnnLength(12), FontStyle.Bold);
text.Bounds = new AnnRectangle(1, 0, printDocument.DefaultPageSettings.PrintableArea.Width, 5, AnnUnit.Millimeter);

container.Objects.Add(text);
container.Draw(image.CreateGdiPlusGraphics().Graphics);
}

Re: Adding a footer before printing

What you have to do is, create an empty white image that is A4 size with 400dpi, or whatever the image's DPI is. Then put the original image on top of the white image. This will give you a new image. Then you can add the text with your code above.

If all of your images are 400dpi. You could easily create a white image in Photoshop or GIMP and load that image, instead of creating one programmatically. Let me know if you are unsure about anything or have questions.

Re: Adding a footer before printing

This solution seems particularly bulky for very large image files. Specifically, the requirement that I form multiple lead objects with the contents of the large bitmap may result in unnecessary slow down of my printing procedure. I am working with an alternative plan, though it does have its challenges. My technique is to write out the header and footer to the printer, and to provide the selected printer hDc to the LEAD.Render call.

' I am using stuff to setup printer and get paper settings, tray settings, etc
' derived from the VB PrinterDlg module (for the lib and a good example search at msdn)

PrinterXYPrint (7.5 - PrinterTextWidth(Title)) / 2, 0#, "My Title"
hDc = Printer.hDc

' removed some stuff that limits the image size to the page size in use...
LEAD1.Render hDc, 1, 1, PrintWidth, PrintHeight

PrinterXYPrint (7.5 - Printer.TextWidth(PageStr)) / 2, ypos, "My Footer String"

Where:
'*** PrinterXYPrint
'***    Draw a string at a specified X,Y location.
Sub PrinterXYPrint(X As Single, Y As Single, S As String)
    On Error Resume Next
    Printer.CurrentX = GConf.PrintLeftMargin + X
    Printer.CurrentY = GConf.PrintTopMargin + Y
    Printer.Print S
End Sub

Now if I could only get the lead image to invariably print out what I see I will be golden.
