update_pixels()¶
Updates the display window with the data in the pixels[] array.
Examples¶

1 2 3 4 5 6 7 8 9 | def setup():
img = py5.load_image("rockies.jpg")
py5.image(img, 0, 0)
half_image = img.width * img.height//2
py5.load_pixels()
for i in range(0, half_image):
py5.pixels[i+half_image] = py5.pixels[i]
py5.update_pixels()
|
Description¶
Updates the display window with the data in the pixels[] array. Use in conjunction with load_pixels(). If you’re only reading pixels from the array, there’s no need to call update_pixels()
— updating is only necessary to apply changes.

update_pixels(x1: int, y1: int, x2: int, y2: int, /) -> None
Parameters¶
x1: int - x-coordinate of the upper-left corner
