Hi, i has the same issue, and i found solution from website of ImageMagick.
Just set gravity as NorthWest then crop your image starting with (0,0).
Sets the current gravity suggestion for various other settings and options.
Choices include: NorthWest, North, NorthEast, West, Center, East,
SouthWest, South, SouthEast. Use -list gravity to get a complete list
of -gravity settings available in your ImageMagick installation.
