• y: Y-coordinate of the pixel.

pixels()

Returns the total number of pixels in the image.

get_pixels()

set_pixels(pixels)

Sets the pixel values of the image from the given array.

• pixels: Array containing pixel values.

set(x, y, color)

Sets the color of the pixel at the specified coordinates.

• x: X-coordinate of the pixel.

Example Usage

import "image"

// Create a new image
img := image.new(255, 255)

for i := 0; i < 255; i++ {
    for j := 0; j < 255; j++ {
        color := [i, 0, j, 255]
        img.set(i, j, color)
    }
}

img.save("out.png", "png")
