AlphaMode can take following values:

• "DISABLE" - opaque texture
• "BLEND" - normal painting on top of the background, obeying alpha channels if present in the image (uses alpha)
• "ALPHAKEY" - one-bit alpha
• "ADD" - additive blend
• "MOD" - modulating blend

Examples

DISABLE: Ignores alpha channel

BLEND: Uses alpha channel

ALPHAKEY: A 1-bit alpha which interprets alpha as either transparent or opaque.

ADD: Uses alpha channel and dodges whites

MOD: Ignores alpha channel and multiplies the image.

Notes

• alphaMode attribute of Texture widget has type AlphaMode.
• As of patch 2.2.0, Blizzard uses only BLEND and ADD AlphaModes in their code.
