## Creating Textures

### New Blank Texture

```
create_texture: name="skin", width=64, height=64, fill_color="#808080"
```

### Texture with Transparency

```
create_texture: name="overlay", width=32, height=32, fill_color=[0, 0, 0, 0]
```

### Apply to Element

```
apply_texture: id="body", texture="skin", applyTo="all"
```

## Painting

### Basic Brush Stroke

```
paint_with_brush: texture_id="skin", coordinates=[
  {x: 10, y: 10},
  {x: 15, y: 12},
  {x: 20, y: 10}
], brush_settings={color: "#FF0000", size: 3, shape: "circle"}
```

### Soft Brush

```
paint_with_brush: texture_id="skin", coordinates=[{x: 32, y: 32}],
  brush_settings={color: "#FFFFFF", size: 10, softness: 50, opacity: 128}
```

### Fill Area

```
paint_fill_tool: texture_id="skin", x=16, y=16, color="#3366FF",
  fill_mode="color_connected", tolerance=10
```

### Fill Entire Face

```
paint_fill_tool: texture_id="skin", x=0, y=0, color="#228B22",
  fill_mode="face"
```

## Shapes & Gradients

### Draw Rectangle

```
draw_shape_tool: texture_id="skin", shape="rectangle",
  start={x: 0, y: 0}, end={x: 16, y: 16}, color="#FFCC00"
```

### Draw Hollow Ellipse

```
draw_shape_tool: texture_id="skin", shape="ellipse_h",
  start={x: 8, y: 8}, end={x: 24, y: 24}, color="#000000", line_width=2
```

### Apply Gradient

```
gradient_tool: texture_id="skin",
  start={x: 0, y: 0}, end={x: 0, y: 32},
  start_color="#87CEEB", end_color="#1E90FF"
```

## Erasing

```
eraser_tool: texture_id="skin", coordinates=[{x: 10, y: 10}, {x: 12, y: 12}],
  brush_size=5, shape="circle", opacity=255
```

## Color Picking

```
color_picker_tool: texture_id="skin", x=16, y=16
# Returns picked color, sets as active
```

## Clone/Copy Brush

```
copy_brush_tool: texture_id="skin",
  source={x: 0, y: 0}, target={x: 32, y: 0},
  brush_size=8, mode="copy"
```

## Brush Presets

### Create Preset

```
create_brush_preset: name="soft_round", size=8, shape="circle",
  softness=30, opacity=200, color="#FFFFFF"
```

### Load Preset

```
load_brush_preset: preset_name="soft_round"
```

## Texture Layers

### Create Layer

```
texture_layer_management: texture_id="skin", action="create_layer",
  layer_name="details"
```

### Set Layer Opacity

```
texture_layer_management: texture_id="skin", action="set_opacity",
  layer_name="details", opacity=75
```

### Merge Down

```
texture_layer_management: texture_id="skin", action="merge_down",
  layer_name="details"
```

## Selections

### Rectangle Selection

```
texture_selection: texture_id="skin", action="select_rectangle",
  coordinates={x1: 0, y1: 0, x2: 16, y2: 16}
```

### Add to Selection

```
texture_selection: texture_id="skin", action="select_ellipse",
  coordinates={x1: 8, y1: 8, x2: 24, y2: 24}, mode="add"
```

### Invert Selection

```
texture_selection: texture_id="skin", action="invert_selection"
```

### Feather Edges

```
texture_selection: texture_id="skin", action="feather_selection", radius=2
```

## UV Mapping

### Auto UV for Mesh

```
auto_uv_mesh: mesh_id="sphere", mode="project"  # project, unwrap, cylinder, sphere
```

### Set Custom UV

```
set_mesh_uv: mesh_id="cube", face_key="north",
  uv_mapping={"v1": [0, 0], "v2": [16, 0], "v3": [16, 16], "v4": [0, 16]}
```

### Rotate UV

```
rotate_mesh_uv: mesh_id="cube", angle="90"
```

## Paint Settings

```
paint_settings: pixel_perfect=true, mirror_painting={enabled: true, axis: ["x"]},
  lock_alpha=true
```

## Common Workflows

### Skin Texture

```
# Create texture
create_texture: name="player_skin", width=64, height=64, fill_color="#C4A484"

# Base colors
paint_fill_tool: x=8, y=8, color="#C4A484", fill_mode="face"  # Face
paint_fill_tool: x=20, y=20, color="#3366CC", fill_mode="face"  # Body

# Details with brush
paint_with_brush: coordinates=[{x: 10, y: 10}, {x: 12, y: 10}],
  brush_settings={color: "#000000", size: 1}  # Eyes

# Apply
apply_texture: id="head", texture="player_skin"
```

### Procedural Pattern

```
# Create base
create_texture: name="pattern", width=32, height=32, fill_color="#FFFFFF"

# Draw grid
draw_shape_tool: shape="rectangle_h", start={x: 0, y: 0}, end={x: 32, y: 32},
  color="#CCCCCC", line_width=1
draw_shape_tool: shape="rectangle_h", start={x: 8, y: 8}, end={x: 24, y: 24},
  color="#999999", line_width=1
```

## Tips

- Use `pixel_perfect=true` in paint_settings for clean pixel art
- Enable `mirror_painting` for symmetrical textures
- Use layers for non-destructive editing
- `lock_alpha` prevents painting outside existing pixels
- Use `fill_mode="color_connected"` to fill only touching same-color pixels
- Create brush presets for frequently used settings
