 convert -composite background.jpg -gravity center tool_marker.png result3.jpg

How can I achieve results from result1 when using convert as executable rather than composite?

Thanks!

You can start by using the operators in the correct order. The "settings" are set first. The "Composite" command is to "read all the settings, and then apply the ONE operation, the command type (traditional UNIX)" Convert "is to" make options as you see them, "while MULTIFUNCTIONAL operations are possible. (Script-like command)

 convert background.jpg tool_marker.png -geometry +50+50 -composite result4.jpg

Note that + 50 + 50 is the location of the upper left corner of the image "tool_marker.png". You will need to subtract the pin-point location on this image to get it at the correct location.

The gravity center (if set before using the -composition operation that uses it) aligns the center of the BOTH images.
