View Source Exray.Textures.Image.Generation (Exray v0.6.0)

Image generation functions like creating gradients, noise maps, raw color

Summary

Functions

gen_image_cellular(width, height, tile_size)

Generate image: cellular algorithm, bigger tileSize means bigger cells

gen_image_checked(width, height, checks_x, checks_y, col1, col2)

Generate image: checked

gen_image_color(width, height, color)

Generate image: plain color

gen_image_gradient_linear(width, height, direction, start, finish)

Generate image: linear gradient, direction in degrees [0..360], 0=Vertical gradient

gen_image_gradient_radial(width, height, density, inner, outer)

Generate image: radial gradient

gen_image_gradient_square(width, height, density, inner, outer)

Generate image: square gradient

gen_image_perlin_noise(width, height, offset_x, offset_y, scale)

Generate image: perlin noise

gen_image_text(width, height, text)

Generate image: grayscale image from text data

gen_image_white_noise(width, height, factor)

Generate image: white noise
