How to distort an image using wand

Question

I'm trying to the same that was asked in this old question but in python using wand.

so far I have done the following:

from wand.image import Image
from wand.display import display

# Paths to your input images
background_path = 'background.png'
source_path = 'source.jpg'
output_path = 'output.jpg'

# Open the background image
with Image(filename=background_path) as background:
    # Open the source image (source)
    with Image(filename=source_path) as source:
        # Define the distortion points
        distortion_points = (
            0, 0, 0, 0,
            265, 0, 540, 85,
            265, 333, 594, 426,
            0, 333, 342, 446
        )

        # Apply the perspective distortion to the blank image
        source.distort('perspective', distortion_points)

        # Composite the background image onto the distorted source
        background.composite(source, 317, 99)

        # Save the resulting image
        background.save(filename=output_path)

display(Image(filename='output.jpg'))

The flower image is distorted and the pixel aren't aligned.

Any idea on how to achieve the same only in python?

EDIT:

This is the current status

current result

expected result

background image

source image

Thanks

I think you need to do it more like this:

#!/usr/bin/env python3

from wand.image import Image
from wand.display import display

# Paths to your input images
background_path = 'background.jpg'
source_path = 'source.jpg'
output_path = 'output.jpg'

# Open the background image
with Image(filename=background_path) as background:
    # Open the source image (source)
    with Image(filename=source_path) as source:
        # Define the distortion points
        distortion_points = (
            0, 0, 317, 99,
            265, 0, 540, 85,
            265, 333, 594, 426,
            0, 333, 342, 446
        )
        # See https://docs.wand-py.org/en/0.6.7/guide/distortion.html
        source.virtual_pixel = 'transparent'
        source.artifacts['distort:viewport'] = f'{background.width}x{background.height}+0+0'

        # Apply the perspective distortion to the blank image
        source.distort('perspective', distortion_points)

        # Composite the distorted source onto the background
        background.composite(source, 0, 0)

        # Save the resulting image
        background.save(filename=output_path)

display(Image(filename='output.jpg'))
