## 📖 Usage Examples
### Basic Drawing Operations
```python
# Create a new sprite
await create_canvas(320, 240, "my_sprite.aseprite")
# Draw pixels
await draw_pixels("my_sprite.aseprite", [
{"x": 10, "y": 10, "color": "FF0000"}, # Red
{"x": 11, "y": 10, "color": "00FF00"}, # Green
{"x": 12, "y": 10, "color": "0000FF"} # Blue
])
# Draw shapes
await draw_rectangle("my_sprite.aseprite", 50, 50, 100, 80, "FFFF00", fill=True)
await draw_circle("my_sprite.aseprite", 160, 120, 30, "FF00FF", fill=False)
await draw_line("my_sprite.aseprite", 0, 0, 320, 240, "FFFFFF", thickness=2)
# Fill area
await fill_area("my_sprite.aseprite", 100, 100, "00FFFF", tolerance=10)
```
### Layer and Frame Management
```python
# Add a new layer
await add_layer("my_sprite.aseprite", "Background")
# Add animation frames
await add_frame("my_sprite.aseprite", after_frame=0)
```
### Palette Operations
```python
# Apply preset palette
await apply_preset_palette("my_sprite.aseprite", "gameboy")
# Available presets: gameboy, gameboy-pocket, nes, pico-8, cga, monochrome, sepia
# Create custom palette
await create_palette("my_sprite.aseprite", [
"264653", "2A9D8F", "E9C46A", "F4A261", "E76F51"
])
# Extract palette from image
await extract_palette_from_image("reference.png", max_colors=16)
# Get palette information
await get_palette_info("my_sprite.aseprite")
# Remap colors
await remap_colors("my_sprite.aseprite", {
"FF0000": "00FF00", # Red to Green
"0000FF": "FFFF00" # Blue to Yellow
})
```
### Export Operations
```python
# Export single file
await export_sprite("my_sprite.aseprite", "output.png", scale=2.0)
# Export with frame range
await export_sprite("animation.aseprite", "frames.gif", frame_range="1-10")
# Export each layer separately
await export_layers("my_sprite.aseprite", "layers/", format="png")
```
### Batch Processing
```python
# Resize multiple sprites
await batch_resize(
input_dir="sprites/",
output_dir="sprites_small/",
scale=0.5,
file_pattern="*.aseprite"
)
# Export batch to PNG
await batch_export(
input_dir="sprites/",
output_dir="exports/",
format="png",
scale=2.0
)
# Apply palette to multiple files
await batch_apply_palette(
input_dir="sprites/",
palette_file="my_palette.aseprite",
create_backup=True
)
# Run custom Lua script on multiple files
await batch_process_custom(
input_dir="sprites/",
lua_script="app.activeSprite:flatten()",
output_dir="flattened/"
)
```

try:
result = await create_canvas(-100, 200, "test.aseprite")
except ValidationError as e:
print(f"Validation failed: {e}")
except AsepriteError as e:
print(f"Aseprite error: {e}")
```
### Lua Script Builder
```python
from aseprite_mcp.core.lua_builder import LuaBuilder
builder = LuaBuilder()
builder.create_sprite(200, 200)
builder.begin_transaction()
builder.set_color("FF0000")
builder.for_loop("i", 0, 10)
builder.draw_pixel("i * 10", "i * 10")
builder.end_loop()
builder.end_transaction()
builder.save_sprite("output.aseprite")
script = builder.build() # Returns clean Lua code
```
