Need oUF help

[Soun]

Hey, I'm trying to get a 1 pixel border around my cast bar's icon in oUF. I'm really not sure how to go about doing it. I have some code here, not expertly written or anything, and I was hoping someone could go over it and tell me what I could add to get a border around the icon.

local Castbar = CreateFrame("StatusBar", nil, self)
	Castbar:SetStatusBarTexture(TEXTURE)
	Castbar:SetStatusBarColor(1/6, 1/6, 2/7)
	Castbar:SetSize(230, 12)
	Castbar:SetPoint('TOP', self, 0, 16)
	Castbar:SetPoint('LEFT', self, 0, 16)
	Castbar:SetPoint('RIGHT', self, 0, 16)
			
	Castbar:SetBackdrop(BACKDROP)
	Castbar:SetBackdropColor(0, 0, 0)

local Icon = Castbar:CreateTexture(nil, "OVERLAY")
	Icon:SetSize(20, 20)
	Icon:SetPoint("TOPRIGHT", self, "TOPRIGHT", 25, 0)

local Time = Castbar:CreateFontString(nil, "OVERLAY")
	Time:SetPoint("RIGHT", Castbar)
	Time:SetFont(FONT, 8, 'OUTLINEMONOCHROME')

local Text = Castbar:CreateFontString(nil, "OVERLAY")
	Text:SetPoint("LEFT", Castbar, 2, 0)
	Text:SetFont(FONT, 8, 'OUTLINEMONOCHROME')

self.Castbar = Castbar
self.Castbar.bg = Background
self.Castbar.Icon = Icon
self.Castbar.Time = Time
self.Castbar.Text = Text

Icon.texture = Icon:CreateTexture()
Icon.texture:SetPoint("TOPLEFT", -1, 1)
Icon.texture:SetPoint("BOTTOMRIGHT", 1, -1)
Icon.texture:SetTexture(0,0,0)

I tried what you wrote Treeston and it didn't work for me (frames didn't load). I do admit though I'm entirely new to LUA and what I've achieved thus far has been a mix of luck and reading. Its quite possible I did something wrong or placed it wrong.

local Castbar = CreateFrame("StatusBar", nil, self)
	Castbar:SetStatusBarTexture(TEXTURE)
	Castbar:SetStatusBarColor(1/6, 1/6, 2/7)
	Castbar:SetSize(230, 12)
	Castbar:SetPoint('TOP', self, 0, 16)
	Castbar:SetPoint('LEFT', self, 0, 16)
	Castbar:SetPoint('RIGHT', self, 0, 16)
			
	Castbar:SetBackdrop(BACKDROP)
	Castbar:SetBackdropColor(0, 0, 0)

local Icon = Castbar:CreateTexture(nil, "OVERLAY")
	Icon:SetSize(20, 20)
	Icon:SetPoint("TOPRIGHT", self, "TOPRIGHT", 25, 0)

	Icon.texture = Icon:CreateTexture("OVERLAY")
	Icon.texture:SetPoint("TOPLEFT", -1, 1)
	Icon.texture:SetPoint("BOTTOMRIGHT", 1, -1)
	Icon.texture:SetTexture(TEXTURE)

local Time = Castbar:CreateFontString(nil, "OVERLAY")
	Time:SetPoint("RIGHT", Castbar)
	Time:SetFont(FONT, 8, 'OUTLINEMONOCHROME')

local Text = Castbar:CreateFontString(nil, "OVERLAY")
	Text:SetPoint("LEFT", Castbar, 2, 0)
	Text:SetFont(FONT, 8, 'OUTLINEMONOCHROME')

self.Castbar = Castbar
self.Castbar.bg = Background
self.Castbar.Icon = Icon
self.Castbar.Time = Time
self.Castbar.Text = Text

That is how I have it placed right now, I just copy pasted first, and it doesn't work like that. Like I said though its more then likely just me. If you wouldn't mind guiding my hand a bit.

Edit:

I got it working with a backdrop. Courtesy of Freebaser on wow-interface.

local Icon = Castbar:CreateTexture(nil, "OVERLAY")
	Icon:SetSize(20, 20)
	Icon:SetPoint("TOPRIGHT", self, "TOPRIGHT", 25, 0)
	Icon:SetTexCoord(.1, .9, .1, .9)

local IconBackdrop = CreateFrame("Frame", nil, Castbar)
        IconBackdrop:SetAllPoints(Icon)
        IconBackdrop:SetFrameStrata("LOW")
        IconBackdrop:SetBackdrop(BACKDROP)
        IconBackdrop:SetBackdropColor(0, 0, 0)
        IconBackdrop:SetBackdropBorderColor(0, 0, 0)
