loadFromFile(path)

local sprite = graphics.loadFromFile("vispath:test.png")

loadMemoryJPG(bytes)

local f = io.open("test.jpg", "rb")
local content = f:read("*all")
f:close()
local sprite = graphics.loadMemoryJPG(content)

loadMemoryPNG(bytes)

local f = io.open("test.png", "rb")
local content = f:read("*all")
f:close()
local sprite = graphics.loadMemoryPNG(content)

loadMemoryWEBP(bytes)

local f = io.open("test.webp", "rb")
local content = f:read("*all")
f:close()
local sprite = graphics.loadMemoryWEBP(content)

drawFont(text, x, y, alpha)

graphics.font = 
graphics.drawFont

drawSprite(sprite, alpha, tint)

drawSpriteWithNineRect(sprite, destRect, nineRect, color, alpha)

drawBox(x, y, w, h, color, alpha)

drawLine(x, y, x2, y2, color, alpha)

drawAnimation(ActiveAnimation, alpha, tint)

isUpsideDown()

true for DirectX and GNM, (0,0) is upper left instead bottom left

clear()

clear current framebuffer

setupOffsets(attribId, size, stride, offset, elementSize)

graphics.setupOffsets(graphics.shaderAttrib(shader, "position"), 2, 20, 0)

drawIndexed(offset, count)

createIndexBuffer(dynamic, size)

createBuffer(dynamic, size)

createFramebuffer(width, height)

bindCurrentTexture(slot)

bindFramebuffer()

reset/bind framebuffer for the scene

addDrawFunc(name, position)

graphics.addDrawFunc("draw()", 0)
function draw()

end

-1 before scene
0 after scene
1 after interfaces

removeDrawFunc(name)

shaderUniform(shader, uniformName, value)

-> Shader Uniforms

shaderCallback(shader, luafunc)

 graphics.shaderCallback(shaderId, "callback")
function callback(object)
    print(object.name)
end

shaderDrawCallback(shader, luafunc)

 graphics.shaderDrawCallback(shaderId, "drawCallback")
function drawCallback(data)

end

Calls the draw function instead of internal drawing.

Data contains the coordinates.

shaderUse(shader)

bind shader and bind textures

shaderAttrib(shader, attrib)

lightmapCallback(callback)

graphics.lightmapCallback("lightmapModify")
function lightmapModify(character, r,g,b)
  local tempR = r
  r = b
  b = tempR
  return r,g,b
end

set lightmap callback -> see example

performLinebreaks(text)

break text into lines

fontDimension(text)

get the dimension of the text with the current font

fontLineHeight()

get the font line height for the current font

fontColor()

get the font color for the current font

noise(pos1, pos2)

simplex perlin noise

noise2(pos1, pos2, pos3, pos4)

perlin noise with up to 4 components

unlockAspectRatio()

unlocks aspect ratio and makes filling the screen possible

lockAspectRatio()

resets aspect ratio

evalTween(from, to, completition, easing)

clipboard()

setScrollPosition(x, y)
