🔒 Stretching verticies

[thick violet]

Hi everyone ! Can someone explain me how do I stretch verticies of an image in pygame, or other libraries except OpenGL? I want it to be like in the screenshot

• Explain what you expect to happen and what actually happens.

does it have to be 2d? you could try a 3d extension of pygame or a 3d engine such as ursina

[thick violet]

yes it has to be 2D

[thick violet]

I'm not using 3D extensions

[high spoke]

well the pygame transformations don't really support the asymmetric scaling of textures like you are trying to achieve

[thick violet]

soo is there a 2d library that can do it?

[high spoke]

honestly it might be easier to use PIL or something to warp the image first and then put it into the game after

[thick violet]

wan you explain more??

import cv2
import numpy as np
from PIL import Image

def apply_perspective_transform(image_path):
    pil_image = Image.open(image_path)
    image = np.array(pil_image)
    image = cv2.cvtColor(image, cv2.COLOR_RGB2BGR)
    height, width = image.shape[:2]

    src_points = np.float32([
        [0, 0], [width, 0], [width, height], [0, height]
    ])

    dst_points = np.float32([
        [width * 0.2, height * 0.2], [width * 0.8, height * 0.1],
        [width * 0.9, height * 0.9], [width * 0.1, height * 0.8]
    ])

    matrix = cv2.getPerspectiveTransform(src_points, dst_points)
    transformed_image = cv2.warpPerspective(image, matrix, (width, height))
    transformed_image = cv2.cvtColor(transformed_image, cv2.COLOR_BGR2RGB)
    transformed_image = Image.fromarray(transformed_image)

    return transformed_image

transformed_image = apply_perspective_transform("img.png")
transformed_image.show()

this is so cursed but it works

if you apply the transformation before you put it into the game

no 2d library that I know of will do it during the runtime

just change around the destination points to whatever looks right

[thick violet]

ooooh it wooorks

thanks a lot man

[high spoke]

np

[thick violet]

oh and the last thing, how do I draw the transformed image from the function on the window? screen.blit does not work

[thick violet]

ah yes screen.blit it's pygame

however do I show it on the screen

nevermind i fixed it
