This is no longer a part of the World of Warcraft API. The backdrop API has been moved to BackdropTemplateMixin It was removed in patch 9.0.1.

The API is no longer being updated here until further notice.

Frames provide two methods to apply tint to their backdrop files:

• SetBackdropColor() tints the background component of a frame's backdrop
• SetBackdropBorderColor() tints the border component of a frame's backdrop

frame:SetBackdropColor(red, green, blue[, alpha])
frame:SetBackdropBorderColor(red, green, blue[, alpha])

Arguments

red

Number - Proportion of the original red colour to remain, from 0 to 1

green

Number - Proportion of the original green colour to remain, from 0 to 1

blue

Number - Proportion of the original blue colour to remain, from 0 to 1

alpha

Number - Proportion of the original opaqueness to remain, from 0 to 1

Notes

• These values only modify the existing colour and alpha of the backdrop files; it its not possible to be lighter or more opaque than the original
• Subsequent calls to the same function will override previous ones; i.e. they apply to the original texture directly rather than interacting with the previously-tinted one

Patch changes

• Patch 1.9.0 (2006-01-03): Added fourth argument, alpha.^[1]
