set_pixels()

Changes the color of any pixel or writes an image directly into the drawing surface.

Examples

def setup():
    for i in range(100):
        for j in range(100):
            c = py5.color(2 * j, 2 * i, 0)
            py5.set_pixels(i, j, c)

def setup():
    img = py5.load_image("laDefense.jpg")
    py5.set_pixels(0, 0, img)

Description

Changes the color of any pixel or writes an image directly into the drawing surface.

The x and y parameters specify the pixel to change and the color parameter specifies the color value. The color parameter c is affected by the current color mode (the default is RGB values from 0 to 255). When setting an image, the x and y parameters define the coordinates for the upper-left corner of the image, regardless of the current image_mode().

Setting the color of a single pixel with py5.set_pixels(x, y) is easy, but not as fast as putting the data directly into pixels[]. The equivalent statement to py5.set_pixels(x, y, 0) using pixels[] is py5.pixels[y*py5.width+x] = 0. See the reference for pixels[] for more information.

Underlying Processing method: set
