How can I find the geometry of my image, following a trim?

Hi
I need to find out where abouts on my image canvas is my image following a trim.

How can I determine the image position on the canvas, using Wand.

The reason is that I have a fixed camera on a rig, but there may be some mechanical slippage, I want to use the offset of the image to calculate compensations to the rig's motion (i.e increase or decrease motor drive parameters).

I think I'm looking for something that I can plug into parse_meta_geometry().

Thanks

I believe you'll want to get the Image.page attribute. Although the value would be a tuple with (width, height, x, y), so no need to use parse_meta_geometry().

from wand.image import Image

with Image(filename="rose.png") as img:
    img.trim()
    myGeo = img.size + img.page[2:]  #=> (70, 46, 100, 75)

Perfect ! Thanks, Eric
