Layer System + +Layers are the fundamental organizational units for PAGX content, providing rich visual effect control capabilities. + +### 4.1 Core Concepts + +This section introduces the core concepts of the layer system. These concepts form the foundation for understanding layer styles, filters, and masks. + +#### Layer Rendering Pipeline + +Painters (Fill, Stroke, etc.) bound to a layer are divided into background content and foreground content via the `placement` attribute, defaulting to background content. A single layer renders in the following order: + +1. **Layer Styles (below)**: Render layer styles positioned below content (e.g., drop shadows) +2. **Background Content**: Render Fill and Stroke with `placement="background"` +3. **Child Layers**: Recursively render all child layers in document order +4. **Layer Styles (above)**: Render layer styles positioned above content (e.g., inner shadows) +5. **Foreground Content**: Render Fill and Stroke with `placement="foreground"` +6. **Layer Filters**: Use the combined output of previous steps as input to the filter chain, applying all filters sequentially + +#### Layer Content + +**Layer content** refers to the complete rendering result of the layer's background content, child layers, and foreground content. Layer styles compute their effects based on layer content. For example, when fill is background and stroke is foreground, the stroke renders above child layers, but drop shadows are still calculated based on the complete layer content including fill, child layers, and stroke. + +#### Layer Contour + +**Layer contour** is used for masking and certain layer styles. Compared to normal layer content, layer contour has these differences: + +1. **Includes geometry drawn with alpha=0**: Geometric shapes filled with completely transparent fills are included in the contour +2. **Solid fills and gradient fills**: Original fills are ignored and replaced with opaque white drawing +3. **Image fills**: Original pixels are preserved, but semi-transparent pixels are converted to fully opaque (fully transparent pixels are preserved) + +Note: Geometry elements must have painters to participate in the contour; standalone geometry elements (Rectangle, Ellipse, etc.) without corresponding Fill or Stroke do not participate in contour calculation. + +Layer contour is primarily used for: + +- **Layer Styles**: Some layer styles require contour as one of their input sources +- **Masking**: `maskType="contour"` uses the mask layer's contour for clipping + +#### Layer Background + +**Layer background** refers to the composited result of all rendered content below the current layer, including: +- Rendering results of all sibling layers below the current layer and their subtrees +- Layer styles already drawn below the current layer (excluding BackgroundBlurStyle itself) + +Layer background is primarily used for: + +- **Layer Styles**: Some layer styles require background as one of their input sources +- **Blend Modes**: Some blend modes require background information for correct rendering + +**Background Pass-through**: The `passThroughBackground` attribute controls whether layer background passes through to child layers. When set to `false`, child layers' background-dependent styles cannot access the correct layer background. The following conditions automatically disable background pass-through: +- Layer uses a non-`normal` blend mode +- Layer has filters applied +- Layer uses 3D transforms or projection transforms + +### 4.2 Layer + +`` is the basic container for content and child layers. + +```xml + + + + + + + + + + + +``` + +#### Child Elements + +Layer child elements are automatically categorized into four collections by type: + +| Child Element Type | Category | Description | +|-------------------|----------|-------------| +| VectorElement | contents | Geometry elements, modifiers, painters (participate in accumulation processing) | +| LayerStyle | styles | DropShadowStyle, InnerShadowStyle, BackgroundBlurStyle | +| LayerFilter | filters | BlurFilter, DropShadowFilter, and other filters | +| Layer | children | Nested child layers | + +**Recommended Order**: Although child element order does not affect parsing results, it is recommended to write them in the order: VectorElement → LayerStyle → LayerFilter → child Layer, for improved readability. + +#### Layer Attributes + +| Attribute | Type | Default | Description | +|-----------|------|---------|-------------| +| `name` | string | "" | Display name | +| `visible` | bool | true | Whether visible | +| `alpha` | float | 1 | Opacity 0~1 | +| `blendMode` | BlendMode | normal | Blend mode | +| `x` | float | 0 | X position | +| `y` | float | 0 | Y position | +| `matrix` | string | identity matrix | 2D transform "a,b,c,d,tx,ty" | +| `matrix3D` | string | - | 3D transform (16 values, column-major) | +| `preserve3D` | bool | false | Preserve 3D transform | +| `antiAlias` | bool | true | Edge anti-aliasing | +| `groupOpacity` | bool | false | Group opacity | +| `passThroughBackground` | bool | true | Whether to pass background through to child layers | +| `excludeChildEffectsInLayerStyle` | bool | false | Whether layer styles exclude child layer effects | +| `scrollRect` | string | - | Scroll clipping region "x,y,w,h" | +| `mask` | idref | - | Mask layer reference "@id" | +| `maskType` | MaskType | alpha | Mask type | +| `composition` | idref | - | Composition reference "@id" | + +**Transform Attribute Priority**: `x`/`y`, `matrix`, and `matrix3D` have an override relationship: +- Only `x`/`y` set: Uses `x`/`y` for translation +- `matrix` set: `matrix` overrides `x`/`y` values +- `matrix3D` set: `matrix3D` overrides both `matrix` and `x`/`y` values + +**MaskType**: + +| Value | Description | +|-------|-------------| +| `alpha` | Alpha mask: Uses mask's alpha channel | +| `luminance` | Luminance mask: Uses mask's luminance values | +| `contour` | Contour mask: Uses mask's contour for clipping | + +**BlendMode**: + +Blend modes define how source color (S) combines with destination color (D). + +| Value | Formula | Description | +|-------|---------|-------------| +| `normal` | S | Normal (overwrite) | +| `multiply` | S × D | Multiply | +| `screen` | 1 - (1-S)(1-D) | Screen | +| `overlay` | multiply/screen combination | Overlay | +| `darken` | min(S, D) | Darken | +| `lighten` | max(S, D) | Lighten | +| `colorDodge` | D / (1-S) | Color Dodge | +| `colorBurn` | 1 - (1-D)/S | Color Burn | +| `hardLight` | multiply/screen reversed combination | Hard Light | +| `softLight` | Soft version of overlay | Soft Light | +| `difference` | \|S - D\| | Difference | +| `exclusion` | S + D - 2SD | Exclusion | +| `hue` | D's saturation and luminosity + S's hue | Hue | +| `saturation` | D's hue and luminosity + S's saturation | Saturation | +| `color` | D's luminosity + S's hue and saturation | Color | +| `luminosity` | S's luminosity + D's hue and saturation | Luminosity | +| `plusLighter` | S + D | Plus Lighter (toward white) | +| `plusDarker` | S + D - 1 | Plus Darker (toward black) | + +### 4.3 Layer Styles + +Layer styles add visual effects above or below layer content without replacing the original content. + +**Input Sources for Layer Styles**: + +All layer styles compute effects based on **layer content**. In layer styles, layer content is automatically converted to **Opaque mode**: geometric shapes are rendered with normal fills, then all semi-transparent pixels are converted to fully opaque (fully transparent pixels are preserved).

Text does not allow direct plain text child nodes; CDATA wrapping is required. + +```xml + + + + + D]]> + + + + + +``` + +**Rendering Modes**: Text supports **pre-layout** and **runtime layout** modes. Pre-layout provides pre-computed glyphs and positions via GlyphRun child nodes, rendering with embedded fonts for cross-platform consistency. Runtime layout performs shaping and layout at runtime; due to platform differences in fonts and layout features, minor inconsistencies may occur. For exact reproduction of design tool layouts, pre-layout is recommended. + +**Runtime Layout Rendering Flow**: +1. Find system font based on `fontFamily` and `fontStyle`; if unavailable, select fallback font according to runtime-configured fallback list +2. Shape using `text` attribute (or CDATA child node); newlines trigger line breaks (default 1.2× font size line height, customizable via TextLayout) +3.
