* For some documents, while the quality is good, their scale is extremly large and the performance of tool decreases. In such cases you can set `-as` (**a**llow **s**caling) to `true`. With this option enabled, the tool will try to rescale the image and only then the layout detection process will begin. * For some documents, while the quality is good, their scale is extremly large and the performance of tool decreases.

* If you care about drop capitals (initials) and headings, you can set `-fl` (**f**ull **l**ayout) to `true`.

With this setting, the tool can currently distinguish 7 document layout classes/elements.
* In cases where the documents include curved headers or curved lines it is obvious that rectangular bounding boxes for textlines will not be a great option. For this, we have developed an option which tries to find contours of the curvy textlines. You can set `-cl` (**c**urved **l**ines) to `true` to enable this option. Be advised that this will increase the time needed for the tool to process the document. * In cases where the document includes curved headers or curved lines, rectangular bounding boxes for textlines will not be a great option. In such cases it is strongly recommended to set the flag `-cl` (**c**urved **l**ines) to `true` to find countours of curved lines instead of rectangular boundinx boxes. Be advised that enabling this option increases the processing time of the tool.
* If you want to crop and save image regions inside the document, just provide a directory with the parameter, `-si` (**s**ave **i**mages). * To crop and save image regions inside the document, set the parameter `-si` (**s**ave **i**mages) to true and provide a directory path to store the extracted images.
