# Pipeline options

Pipeline options allow to customize the execution of the models during the conversion pipeline.
This includes options for the OCR engines, the table model as well as enrichment options which
can be enabled with `do_xyz = True`.


This is an automatic generated API reference of the all the pipeline options available in Docling.

## LaTeX TikZ Rendering

Docling's LaTeX backend can optionally render `tikzpicture` environments into
images using the Tectonic engine.

### Backend options

`LatexBackendOptions` supports the following TikZ-related options:

- `tikz_engine`
  Set to `"tectonic"` to enable optional TikZ rendering.
- `tikz_engine_timeout`
  Sets the timeout, in seconds, for rendering a single TikZ diagram.
- `tikz_engine_allow_shell_escape`
  Defaults to `False`. Enable this only when required by the input document,
  since shell escape is less safe for untrusted LaTeX sources.

### CLI flags

The CLI exposes the same behavior with these flags:

- `--tikz-engine` / `-T`
- `--tikz-engine-timeout`
- `--tikz-shell-escape`

### Fallback behavior

- When Tectonic compilation succeeds, the TikZ diagram is rasterized and stored
  as an image.
- When compilation fails, times out, produces no PDF, or rasterization fails,
  Docling preserves the original TikZ source as fallback code metadata instead
  of dropping the figure.
