Detailed Description

TransparencePrimitive2D class.

This is the basic primitive for applying freely defined transparence to freely defined content. The basic idea is to associate a content which is defined as a sequence of primitives and hold as child content in the GroupPrimitive2D with a transparence channel also defined as a sequence of primitives and hold in the transparence member.

The basic definition is to use the transparence content as transparence-Mask by interpreting the transparence-content not as RGB, but as Luminance transparence mask using the common RGB_to_luminance definition as e.g. used by VCL.

The defining geometry is the Range of the child primitive sequence, this means the renderers will/shall use this geometric information for rendering, not the transparent one. The transparent one should/will be clipped accordingly.

◆ TransparencePrimitive2D()

drawinglayer::primitive2d::TransparencePrimitive2D::TransparencePrimitive2D ( Primitive2DContainer &&  rChildren,

constructor

Parameters
rChildrenThe content which is defined to have a transparency. The range of this primitive is defined by this content
rTransparenceThe definition of the Transparence-channel for this primitive. It will be interpreted as mask by interpreting as gray values using the common RGB_to_luminance definitions
