LibPixelPerfect

WoW addon library to allow for pixel perfection by finding the right pixel sizes for your resolution. Very useful for textures, particularly small textures, to ensure consistent rendering and eliminate distortion.

Currently only supports clients with PixelUtil (Retail, Classic, Classic Era). Any "unofficial" flavors of the game may not work.

Usage

Using this library is similar to other libraries that use LibStub.

Embedding the Library

To use this library, embed it in your addon by adding the following to your .pkgmeta file (The Libs/ paths are just examples):

externals:
  # your other externals...
  Libs/LibStub: https://repos.wowace.com/wow/ace3/trunk/LibStub
  Libs/LibPixelPerfect-1.0: https://github.com/McTalian/LibPixelPerfect-1.0/LibPixelPerfect-1.0

Then include it into either an XML file or your Toc file:

embeds.xml example (assuming it is next to the Libs/ folder):

&lt;Ui xsi:schemaLocation="http://www.blizzard.com/wow/ui/ ..\FrameXML\UI.xsd"&gt;
  &lt;Script file="Libs\LibStub\LibStub.lua"/&gt;
  &lt;Include file="Libs\LibPixelPerfect-1.0\lib.xml"/&gt;
&lt;/Ui&gt;

YourAddon.toc example:

## Interface: 110200
## Title: Your Addon

# If you use embeds.xml
# embeds.xml

# Otherwise
Libs/LibStub/LibStub.lua
Libs/LibPixelPerfect-1.0/lib.xml

YourAddon.lua

Using the Library

Once the library is embedded (or otherwise available to your addon), you can use it in your Lua code like the following example.

YourAddon.lua example:

local LPP = LibStub("LibPixelPerfect-1.0")

local frame = CreateFrame("Frame", nil, UIParent)
LPP.PSize(frame, 400, 400)
frame:SetPoint("CENTER")

local background = frame:CreateTexture(nil, "BACKGROUND")
background:SetAllPoints(frame)
background:SetColorTexture(0, 0, 0, 1)

local topBar = frame:CreateTexture(nil, "ARTWORK")
topBar:SetColorTexture(1, 1, 1, 1)
topBar:SetPoint("TOP", frame, "TOP", 0, LPP.PScale(-400/4))
LPP.PHeight(topBar, 1)
LPP.PWidth(topBar, 400/2)
local rightBar = frame:CreateTexture(nil, "ARTWORK")
rightBar:SetColorTexture(1, 1, 1, 1)
rightBar:SetPoint("RIGHT", frame, "RIGHT", LPP.PScale(-400/4), 0)
LPP.PWidth(rightBar, 1)
LPP.PHeight(rightBar, 400/2)
local bottomBar = frame:CreateTexture(nil, "ARTWORK")
bottomBar:SetColorTexture(1, 1, 1, 1)
bottomBar:SetPoint("BOTTOM", frame, "BOTTOM", 0, LPP.PScale(400/4))
LPP.PHeight(bottomBar, 1)
LPP.PWidth(bottomBar, 400/2)
local leftBar = frame:CreateTexture(nil, "ARTWORK")
leftBar:SetColorTexture(1, 1, 1, 1)
leftBar:SetPoint("LEFT", frame, "LEFT", LPP.PScale(400/4), 0)
LPP.PHeight(leftBar, 400/2)
LPP.PWidth(leftBar, 1)

frame:Show()
