Code Examples

client

local texture = dxCreateTexture(4, 4) -- Create a texture
local pixel = dxGetTexturePixels(texture) -- Get pixel element
local sx, sy = dxGetPixelsSize(pixel) -- Get pixel size
local tab = {} -- Define a table
for i = 0, sx - 1 do -- From 0th pixel to 3th pixel in width
    tab[i + 1] = {} -- Define a table
    for j = 0, sy - 1 do -- From 0th pixel to 3th pixel in height
        local r, g, b, a = dxGetPixelColor(pixel, i, j) -- Get pixel color
        tab[i + 1][j + 1] = {r, g, b, a} -- Save the color in the table
