# TileIterator
> 
# class pixeltable.iterators.TileIterator
Iterator over tiles of an image. Each image will be divided into tiles of size `tile_size`, and the tiles will be
iterated over in row-major order (left-to-right, then top-to-bottom). An optional `overlap` parameter may be
specified. If the tiles do not exactly cover the image, then the rightmost and bottommost tiles will be padded with
blackspace, so that the output images all have the exact size `tile_size`.
Args:
image: Image to split into tiles.
tile\_size: Size of each tile, as a pair of integers `[width, height]`.
overlap: Amount of overlap between adjacent tiles, as a pair of integers `[width, height]`.
## method close()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
close() -> None
```
Close the iterator and release all resources
## method create()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
create(**kwargs: Any) -> tuple[type[ComponentIterator], dict[str, Any]]
```
## method input\_schema()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
input_schema(
*args: Any,
**kwargs: Any
) -> dict[str, pixeltable.type_system.ColumnType]
```
Provide the Pixeltable types of the init() parameters
The keys need to match the names of the init() parameters. This is equivalent to the parameters\_types
parameter of the @function decorator.
## method output\_schema()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
output_schema(
*args: Any,
**kwargs: Any
) -> tuple[dict[str, pixeltable.type_system.ColumnType], list[str]]
```
Specify the dictionary returned by next() and a list of unstored column names
**Returns:**
* `tuple[dict[str, pixeltable.type_system.ColumnType], list[str]]`: a dictionary which is turned into a list of columns in the output table
a list of unstored column names
## method set\_pos()
```python theme={"theme":{"light":"light-plus","dark":"dark-plus"}}
set_pos(pos: int) -> None
```
Set the iterator position to pos
