S_MERGE is a versatile tool for merging two images. Useful for overlaying political and relief maps or inserting a watermark in your pictures.
Total flexibility in alignment of the images such as scaling, relative positioning and rotation is allowed
with many options available for blending the images together. These include edge fading to remove the
inappropriate edges seen as a result of merging two images of different sizes and positions.
Other options include generation of a cylindrical panoramic projection from a flat picture and overlaying
a dotted and/or a solid line grid on the image.
