## Quantum Painter Configuration :id=quantum-painter-config
| Option | Default | Purpose |
|-----------------------------------------|---------|---------------------------------------------------------------------------------------------------------------------------------------------|
|------------------------------------------|---------|---------------------------------------------------------------------------------------------------------------------------------------------|
| `QUANTUM_PAINTER_NUM_IMAGES` | `8` | The maximum number of images/animations that can be loaded at any one time. |
| `QUANTUM_PAINTER_NUM_FONTS` | `4` | The maximum number of fonts that can be loaded at any one time. |
| `QUANTUM_PAINTER_CONCURRENT_ANIMATIONS` | `4` | The maximum number of animations that can be executed at the same time. |
| `QUANTUM_PAINTER_LOAD_FONTS_TO_RAM` | `FALSE` | Whether or not fonts should be loaded to RAM. Relevant for fonts stored in off-chip persistent storage, such as external flash. |
| `QUANTUM_PAINTER_PIXDATA_BUFFER_SIZE` | `32` | The limit of the amount of pixel data that can be transmitted in one transaction to the display. Higher values require more RAM on the MCU. |
| `QUANTUM_PAINTER_SUPPORTS_256_PALETTE` | `FALSE` | If 256-color palettes are supported. Requires significantly more RAM on the MCU. |
| `QUANTUM_PAINTER_SUPPORTS_NATIVE_COLORS` | `FALSE` | If native color range is supported. Requires significantly more RAM on the MCU. |
| `QUANTUM_PAINTER_DEBUG` | _unset_ | Prints out significant amounts of debugging information to CONSOLE output. Significant performance degradation, use only for debugging. |
Drivers have their own set of configurable options, and are described in their respective sections.
