Enum BlendMode

Namespace

Sdl3Sharp.Video.Blending

Assembly

Sdl3Sharp.dll

Represents a blend mode used in drawing operations

public enum BlendMode : uint

Fields

Add = 2

Additive blending

dstRGB = (srcRGB * srcA) + dstRGB
dstA = dstA

AddPremultiplied = 32

Pre-multiplied additive blending

dstRGB = srcRGB + dstRGB
dstA = dstA

Blend = 1

Alpha blending

dstRGB = (srcRGB * srcA) + (dstRGB * (1 - srcA))
dstA = srcA + (dstA * (1 - srcA))

BlendPremultiplied = 16

Pre-multiplied alpha blending

dstRGBA = srcRGBA + (dstRGBA * (1 - srcA))

Invalid = 2147483647

A representative for an invalid BlendMode

Modulate = 4

Color modulate

dstRGB = srcRGB * dstRGB
dstA = dstA

Multiply = 8

Color multiply

dstRGB = (srcRGB * dstRGB) + (dstRGB * (1 - srcA))
dstA = dstA

None = 0

No blending

dstRGBA = srcRGBA

Remarks

The defined blend modes in the BlendMode enumeration are supported everywhere.

Additional custom blend modes can be obtained by using ComposeCustom(BlendFactor, BlendFactor, BlendOperation, BlendFactor, BlendFactor, BlendOperation). Notice that not all renderers support all custom blend modes.
