### Summary Duplicate PR of #1259 because of issues with checks Closes #1227, which found that `nan` values were present in the coordinates being generated for some elements. This breaks logic out from `add_pytesseract_bbox_to_elements` to new functions `_get_element_box` and `convert_multiple_coordinates_to_new_system`. It also updates the logic to check that the current bounding box matches the first character of the element's text (as to avoid the `~` characters that `pytesseract.image_to_boxes` includes, but are not present in `pytesseract.image_to_string`. ### Testing ``` from unstructured.partition.image import partition_image from PIL import Image, ImageDraw filename="example-docs/layout-parser-paper-with-table.jpg" elements = partition_image(filename=filename, strategy="ocr_only") image = Image.open(filename) draw = ImageDraw.Draw(image) for i, element in enumerate(elements): print(i, element.metadata.coordinates) if element.metadata.coordinates: draw.polygon(element.metadata.coordinates.points, outline="red", width=2) output = "example-docs/box-layout-parser-paper-with-table.jpg" image.save(output) image.close() ``` --------- Co-authored-by: qued <64741807+qued@users.noreply.github.com> Co-authored-by: cragwolfe <crag@unstructured.io> Co-authored-by: Yao You <theyaoyou@gmail.com>
