pxl

Lightweight pixel drawing library for ComputerCraft.

How to use:

let's create a pxl object first.

local lib = require "pxl"
local canvas = lib.new(term, colors.black)

and then... plot the pixels!

canvas.canvas[y][x] = colors.red
-- or you wanna use this:
canvas:set_pixel(x,y, colors.red)

we also can draw some text:

canvas:write_text(1,1,"hello usr!", true, colors.black, colors.white)

AND WE RENDER IT!

canvas:render()

and this is how to use library.

API

pxl.new(term, backgorund_color)

Basically jsut creates new pxl object.

local lib = require "pxl"
local obj = lib.new(term, colors.black)

pxl.restore(PXL_OBJ, background_color)

Creates a new buffer canvas for PXL_OBJ

local lib = require "pxl"
local obj = lib.new(term, colors.black)
lib.restore(obj, colors.yellow) -- this is replace our old buffer with black colors to new with yellow colors.

pxl.restore_chars(PXL_OBJ, char, fg, bg)

local lib = require "pxl"
local obj = lib.new(term, colors.black)
lib.restore_chars(obj, "", colors.white, colors.black) -- this will clear chars buffer because chars with zero(like "") length just ignored.

pxl:set_pixel(x,y,color)

Plots pixel at x,y.

local lib = require "pxl"
local obj = lib.new(term, colors.black)
obj:set_pixel(10,10, colors.yellow)

or you can use

local lib = require "pxl"
local obj = lib.new(term, colors.black)
obj.canvas[10][10] = colors.yellow -- the important thing that coordinates are Y,X not X,Y

pxl:write_text(x,y, text, bounds_check, bg, fg)

Just writes text instead of pixels, may cause issues because text draws over the pixels

local lib = require "pxl"
local obj = lib.new(term, colors.black)
obj:write_text(5,5, "hello my friend :)", true, colors.black, colors.white)
obj:render()

pxl:is_in_bounds(x,y)

Just checks if x and y is in bounds

local lib = require "pxl"
local obj = lib.new(term, colors.black)
if obj:is_in_bounds(1000,1000) then
    obj.canvas[1000][1000] = colors.pink
end
obj:render()

pxl:render()

Just draws the pixels, thats it.

local lib = require "pxl"
local obj = lib.new(term, colors.black)
obj:render()
