C API

Types

typedef void (*ImageFreeFunc)(void *data);

Used for freeing both the pixels (must be referenced in the user data) and the user data associated with the image.

typedef void (*MulticoreFunc)(int from, int to, void *data);

Used for running the code on multiple cores.

Functions

Value fiximage_create(Heap *heap, int width, int height);

Creates a new image.

Value fiximage_create_from_pixels(Heap *heap, int width, int height, int stride, uint32_t *pixels, ImageFreeFunc free_func, void *user_data, int type);

Creates a new image from given pixels. You must deallocate the pixels and the user data in case of a failure. Use -1 as a type if you don't need custom types.

Value fiximage_create_painter(Heap *heap, Value img, int offset_x, int offset_y);

Creates a new painter for given image.

int fiximage_get_data(Heap *heap, Value img, int *width, int *height, int *stride, uint32_t **pixels, void **user_data, int *type);

Returns the data for given image. All output parameters are optional.

int fiximage_get_painter_data(Heap *heap, Value p, float *tr, int *clip, Value *image);

Returns the data for given painter. All output parameters are optional.

void fiximage_register_functions(Heap *heap);

Registers image functions to given heap.

int fiximage_get_core_count();

Returns the number of CPU cores.

void fiximage_multicore_run(int from, int to, int min_iters, MulticoreFunc func, void *data);

Runs the code on multiple CPU cores.
