update_pixels()

Updates the display window with the data in the pixels[] array.

Examples

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.

Underlying Processing method: updatePixels
