```
Parameters
| Name | Type | Description |
| ----------- | ---------- | -------------------------------------------------------------------------------------------------------- |
| `new_size` | `uint32_t` | new size of the cache in bytes. |

bool lv_image_cache_is_enabled(void)
```
**Returns:** `bool` — true: enabled, false: disabled.
lv_image_cache_iter_create [#lv_image_cache_iter_create]
Create an iterator to iterate over the image cache.
```c title=" " lineNumbers=1
lv_iter_t * lv_image_cache_iter_create(void)
```
