Represents the display type of the layer. You can also set a value.
- Specifying ltOpaque or ltCoverRect disables per-pixel alpha blending. ltCoverRect and ltOpaque have the same meaning.
If the Layer.opacity property is 255, it will be displayed as a completely opaque rectangle. Mask images are ignored. The drawing method (specified by Layer.face) suitable for this type is dfOpaque.
- Specifying ltAlpha or ltTransparent enables per-pixel alpha blending. ltTransparent and ltAlpha have the same meaning.
The mask image is used for transmission. dfAlpha is the preferred drawing method for this type.
- Specifying ltAddAlpha enables pixel-by-pixel additive alpha blending. The preferred drawing method for this type is dfAddAlpha.
- If ltAdditive is specified, additive composition is performed. Mask images are ignored. The preferred drawing method for this type is dfOpaque.
- If ltSubtractive is specified, subtractive synthesis is performed. Mask images are ignored. The preferred drawing method for this type is dfOpaque.
- If ltMultiplicative is specified, multiplication synthesis is performed. Mask images are ignored. The preferred drawing method for this type is dfOpaque.
- If ltDodge is specified, dodging is performed. Mask images are ignored. The preferred drawing method for this type is dfOpaque.
- If ltDarken is specified, comparison (dark) synthesis is performed. Mask images are ignored. The preferred drawing method for this type is dfOpaque.
- If ltLighten is specified, comparison (bright) synthesis is performed. Mask images are ignored. The preferred drawing method for this type is dfOpaque.
