1. overscan: if you mean border around the image, you could use BorderRemove (1-bit images) or AutoTrim (all types of images).

2. HalfTones Removal: I'm not sure what you mean by this. What does the image contain exactly, and how do you want it modified?

3. Noise Removal: We have different filters that might help you to reduce the noise in the image. If the image is colored, you can use one of the following filters:
- Average Filter Bitmap
- Gaussian Filter Bitmap
- Median Filter Bitmap
- Smooth Edges Bitmap

If the image is 1-bit, you can use one of the following filters:
- Despeckle Bitmap
- Smooth Bitmap
- Border Remove Bitmap
- Color Bitmap Rgn
- Dot Remove Bitmap
- Hole Punch Remove Bitmap
- Inverted Text Bitmap
- Line Remove Bitmap

4. Fit To Height: This depends on the LEADTOOLS programming interface you're using, but can generally be implemented through our painting functions.
