ImageMagick
Resize image
convert img1_1680-1050.jpg -resize 1920 a01.jpg
will create an image that is 1920 pixels wide. The height is determined automatically.
Create spanning image
convert a01.jpg a02.jpg +append a03.jpg
will create a horizontal image suitable for two monitor span. Please note in this example the height of the image will be 1200px which gives us a little problem when applying to desktop. To append two images together they should have the same dimensions!
Crop image
convert a03.jpg -crop 3840x1080+0x0 a04.jpg
will crop to two full HD monitor resolution (3840×1080), starting at the upper left corner(0x0).
