-- shapes.lua - Minimap shape masks for SexyMap OctoWoW Edition
|
|
-- Provides CApplyShape() which clips the minimap to a given shape
|
|
--
|
|
-- IMPORTANT: We use Minimap:SetMaskTexture() instead of creating overlay textures.
|
|
-- Creating an overlay texture on top of the minimap blocks the map content and causes
|
|
-- the minimap to appear as pure white. SetMaskTexture clips the minimap to the shape
|
|
-- without covering it.
|
|
--
|
|
-- In WoW 1.12, SetMaskTexture(nil) does NOT remove the mask — it falls back to
|
|
-- the default round mask. This means there is no way to show a truly square
|
|
-- minimap via mask alone. For square shapes, we use the circle mask and rely
|
|
-- on the border/backdrop visuals to give a square appearance.
|
|
|
|
local _G = getfenv(0)
|
|
|
|
-- The default round minimap mask.
|
|
-- IMPORTANT: "Interface\Minimap\UI-Minimap-Background" is NOT a mask — it's a
|
|
-- decorative border texture. Using it with SetMaskTexture causes green rendering.
|
|
-- The correct default mask is the circle.blp we ship with the addon.
