  \includegraphics[scale=0.5]{filename}

• You can resize to a fixed width, using width and height options as in the previous recipe.

• You can rotate by specifying a clockwise rotation angle, like so:

  \includegraphics[angle=90,origin=tl]{filename}

• You can trim and clip, like here, where we cut off 1 cm at the left, 2 cm at the bottom, 3 cm at the right, and 4...
