Defining the rotation center within a composition
Posted: 2010-02-21T11:48:33-07:00
Dear IM-Users,
I have one background (theme.jpg) where i want to position an resized .jpg image (pic.jpg) on it.
Very often this pic.jpg needs to be rotated by its center point, which is driving me crazy.
The rotation is done by its bottom left corner (if value>0). I need to rotate the image by its center point.
Any hint how to do this?
1. No Rotation
2. rotate 20
Here are the source images:

Thank you in advance

Code: Select all
1. composite -geometry +70+81 \( pic.jpg[200x178] -matte -background none \) theme.jpg
2. composite -geometry +70+81 \( pic.jpg[200x178] -rotate 20 -matte -background none \) theme.jpg out2.jpg
2. rotate 20
