説明
 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.
