Python魔杖从修剪中偏移

Question

I'm using Wand in Python for manipulating my images. I'm using the .trim() function to auto-crop these images.

The resulting image gives me the new size, obviously. But I can't figure out how to get the offset from the original image.

The documentation is pretty sparse.

In Imagemagick, you can use :info and you get the offset for trim (and the new size).

Is there a way to get the offset information using Wand?

Answer 1

Use wand.image.Image.page which will return the size + offset.

with Image(filename="input.png") as img:
    img.trim()
    offset = img.page[2:]  # => (x, y)

There's also page_x & page_y properties introduced in version 0.4.3.
