The QMK CLI can be used to convert from normal images such as PNG files or animated GIFs, as well as fonts from TTF files.

### ** Common: Surfaces **
### ** OLED **
Quantum Painter has surface drivers which are able to target a buffer in RAM. In general, surfaces keep track of the "dirty" region -- the area that has been drawn to since the last flush -- so that when transferring to the display they can transfer the minimal amount of data to achieve the end result.
OLED displays tend to use 5-pin SPI when at larger resolutions, or when using color -- SPI SCK, SPI MOSI, SPI CS, D/C, and RST pins. Smaller OLEDs may use I2C instead.
!> These generally require significant amounts of RAM, so at large sizes and/or higher bit depths, they may not be usable on all MCUs.
When using these displays, either `spi_master` or `i2c_master` must already be correctly configured for both the platform and panel you're building for.
For SPI, the pin assignments for SPI CS, D/C, and RST are specified during device construction -- for I2C the panel's address is specified instead.

QUANTUM_PAINTER_ENABLE = yes

Creating a SSD1351 device in firmware can then be done with the following API:
```c
painter_device_t qp_rgb565_make_surface(uint16_t panel_width, uint16_t panel_height, void *buffer);
painter_device_t qp_ssd1351_make_spi_device(uint16_t panel_width, uint16_t panel_height, pin_t chip_select_pin, pin_t dc_pin, pin_t reset_pin, uint16_t spi_divisor, int spi_mode);
```
The `buffer` is a user-supplied area of memory, and is assumed to be of the size `sizeof(uint16_t) * panel_width * panel_height`.
The device handle returned from the `qp_ssd1351_make_spi_device` function can be used to perform all other drawing operations.
The device handle returned from the `qp_rgb565_make_surface` function can be used to perform all other drawing operations.

### ** Surface **
Quantum Painter has a surface driver which is able to target a buffer in RAM. In general, surfaces keep track of the "dirty" region -- the area that has been drawn to since the last flush -- so that when transferring to the display they can transfer the minimal amount of data to achieve the end result.
!> These generally require significant amounts of RAM, so at large sizes and/or higher bit depths, they may not be usable on all MCUs.
Enabling support for surfaces in Quantum Painter is done by adding the following to `rules.mk`:
```make
QUANTUM_PAINTER_ENABLE = yes
QUANTUM_PAINTER_DRIVERS += surface
```
Creating a surface in firmware can then be done with the following APIs:
```c
// 16bpp RGB565 surface:
painter_device_t qp_make_rgb565_surface(uint16_t panel_width, uint16_t panel_height, void *buffer);
// 1bpp monochrome surface:
painter_device_t qp_make_mono1bpp_surface(uint16_t panel_width, uint16_t panel_height, void *buffer);
```
The `buffer` is a user-supplied area of memory, which can be statically allocated using `SURFACE_REQUIRED_BUFFER_BYTE_SIZE`:
```c
// Buffer required for a 240x80 16bpp surface:
uint8_t framebuffer[SURFACE_REQUIRED_BUFFER_BYTE_SIZE(240, 80, 16)];
```
The device handle returned from the `qp_make_?????_surface` function can be used to perform all other drawing operations.
Example:
```c
static painter_device_t my_surface;
static uint16_t my_framebuffer[320 * 240]; // Allocate a buffer for a 320x240 RGB565 display
static uint8_t my_framebuffer[SURFACE_REQUIRED_BUFFER_BYTE_SIZE(240, 80, 16)]; // Allocate a buffer for a 16bpp 240x80 RGB565 display
void keyboard_post_init_kb(void) {
my_surface = qp_rgb565_make_surface(320, 240, my_framebuffer);
my_surface = qp_rgb565_make_surface(240, 80, my_framebuffer);
qp_init(my_surface, QP_ROTATION_0);
keyboard_post_init_user();
}
```
The maximum number of RGB565 surfaces can be configured by changing the following in your `config.h` (default is 1):
The maximum number of surfaces can be configured by changing the following in your `config.h` (default is 1):
```c
// 3 surfaces:
#define RGB565_SURFACE_NUM_DEVICES 3
#define SURFACE_NUM_DEVICES 3
```
To transfer the contents of the RGB565 surface to another display, the following API can be invoked:
To transfer the contents of the surface to another display of the same pixel format, the following API can be invoked:
```c
bool qp_rgb565_surface_draw(painter_device_t surface, painter_device_t display, uint16_t x, uint16_t y);
bool qp_surface_draw(painter_device_t surface, painter_device_t display, uint16_t x, uint16_t y);
```
The `surface` is the surface to copy out from. The `display` is the target display to draw into. `x` and `y` are the target location to draw the surface pixel data. Under normal circumstances, the location should be consistent, as the dirty region is calculated with respect to the `x` and `y` coordinates -- changing those will result in partial, overlapping draws.
?> Calling `qp_flush()` on the surface resets its dirty region. Copying the surface contents to the display also automatically resets the dirty region.
!> The surface and display panel must have the same native pixel format.
