| D | display-manager.rst | 87 Blend Mode Properties
90 Pixel blend mode is a DRM plane composition property of :c:type:`drm_plane` used to
92 background plane (bg). Here, we present main concepts of DRM blend mode to help
97 Basically, a blend mode sets the alpha blending equation for plane
115 DRM has three blend mode to define the blend formula in the plane composition:
117 * **None**: Blend formula that ignores the pixel alpha.
119 * **Pre-multiplied**: Blend formula that assumes the pixel color values in a
122 * **Coverage**: Blend formula that assumes the pixel color values were not
125 and pre-multiplied is the default pixel blend mode, that means, when no blend
128 provides a set of subtests to verify plane alpha and blend mode properties.
