Hi,
Can you please help me in finding out the equivalent Methods in dotnet for the following methods in LeadTools 13.0 version:
1. Lead1.SetSrcRect
2. Lead1 .SetSrcClipRect
3. Lead1.SetDstRect
4. Lead1.SetDstClipRect
I have used these methods to scale my Images as Fit To Height, Fit To Width, Best Fit, Actual Size. Presently LeadTools dotnet version supports Fit, Fit To Width, Fit Always, Stretch which will not support my purpose. If the above mentioned methods does not exist in dotnet version then please help me out to support my Application purpose.

You never mentioned what version of LEADTOOLS you are using now. You mentioned .NET libraries, but 14.5 and 15 have some differences. Luckily for you, the answer is the same for both versions, but in the future it would save time if you mentioned your version along with your interface.
These four properties were used for customizing how the image gets painted. With the LEAD Main Control these properties have default values and get used automatically, but with the .NET interface, they are only used with manual painting. Take a look at the RasterImage.Paint function. There are several overloads, but each version has at least one overload that takes in four rectangles: srcRect, srcClipRect, destRect, and destClipRect.

Attached is a simple C#.NET 2005 project that uses the LEADTOOLS v15 libraries and shows how to:
1. Use the RasterImage.Paint method to fit an image to its height
2. Use the RasterImage.Paint method to stretch an image to fit the form
3. Over-ride the OnPaint event of a Windows Form
Obviously, you will probably want to change the destination rectangle to suit your form's layout better, but this is intended to show you the basics so you can incorporate it into your implementation. Also, you are not limited to painting to just the form, you can paint to any Graphics object you have available.
