I am working with, sometimes, thousands of tiffs and, of which, most are multipage. I currently have software that I know uses Lead Tools v12 but I do not have access to the source. The program is suppose to run through all of the tiffs and, if specified, stamps the tiffs with a specified number, and the end product is single-page, stamped tiffs. What I need to know, first of all, is if this will even be worth redoing with v14.5 and C# .NET 2.0 vs v12 and VB6. Secondly, I need to know what my best approach would be to split the tiffs and stamp them. I know there are a lot of articles out there about writing text on an image, but I specifically need the output tiffs to be group 4 compressed (which is 1bpp and i have had many problems with changing back to 1bpp from a graphics object after writing on it.) If anyone has any examples or links to examples it would be much appreciated. Thanks in advance!

It is fairly easy to do this with LEADTOOLS using either VB6 or C#.NET.
The general steps, which are syntax-independent, are:
1. Load a page of the TIFF file.
2. Obtain a GDI drawing object (device context) for the image and draw the text. (implicit step in the Main OCX)
3. Save as 1-bit CCITT Group 4 to a new file name.
Note that 1-bit images are compatible with GDI, so you don't need to convert among different bit depths before and after drawing.
