Enum BlendFactor Source #	Composite operation The composite operations in NanoVG are modeled after HTML Canvas API, and the blend func is based on OpenGL (see corresponding manuals for more info). The colors in the blending state have premultiplied alpha.

globalCompositeOperation :: Context -> CompositeOperation -> IO () Source #

Sets the composite operation. The op parameter should be one of NVGcompositeOperation.

globalCompositeBlendFunc :: Context -> BlendFactor -> BlendFactor -> IO () Source #

Sets the composite operation with custom pixel arithmetic. The parameters should be one of NVGblendFactor.

globalCompositeBlendFuncSeparate :: Context -> BlendFactor -> BlendFactor -> BlendFactor -> BlendFactor -> IO () Source #

Sets the composite operation with custom pixel arithmetic for RGB and alpha components separately. The parameters should be one of NVGblendFactor.
