Chapter 29 ■ Widget Reference 1139Texture has all the methods from Region, VisibleRegion and LayeredRegion, plusthe following:GetBlendModeReturns the blend mode of the texture.mode = Texture:GetBlendMode()Returns:mode—Blend mode of the texture (string)ADD - Adds texture color values to the underlying color values, using thealpha channel; light areas in the texture lighten the background while darkareas are more transparentALPHAKEY - One-bit transparency; pixels with alpha values greater than ∼0.8are treated as fully opaque and all other pixels are treated as fully transparentBLEND - Normal color blending, using any alpha channel in the texture imageDISABLE - Ignores any alpha channel, displaying the texture as fully opaqueMOD - Ignores any alpha channel in the texture and multiplies texturecolor values by background color values; dark areas in the texturedarken the background while light areas are more transparentGetNonBlockingReturns whether the texture object loads its image file in the background.nonBlocking = Texture:GetNonBlocking()See :SetNonBlocking() for further details.Returns:nonBlocking—1 if the texture object loads its image file in the background;nil if the game engine is halted while the texture loads (1nil)GetTexCoordReturns corner coordinates for scaling or cropping the texture image.ULx, ULy, LLx, LLy, URx, URy, LRx, LRy = Texture:GetTexCoord()See Texture:SetTexCoord() example for details.Returns:ULx—Upper left corner X position, as a fraction of the image’s width from theleft (number)ULy—Upper left corner Y position, as a fraction of the image’s height from thetop (number)LLx—Lower left corner X position, as a fraction of the image’s width from theleft (number)LLy—Lower left corner Y position, as a fraction of the image’s height from thetop (number)URx—Upper right corner X position, as a fraction of the image’s width from theleft (number)URy—Upper right corner Y position, as a fraction of the image’s height from thetop (number)
