Inspect revised block bounding boxes

Description

Tool to visually check the order of block bounding boxes after manual processing (e.g. block reordering or splitting). Takes as its main input a token dataframe generated with build_token_df(), reassign_tokens(), or reassign_tokens2(). The function plots the block bounding boxes onto images of the submitted document. Generates an annotated .png file for each page in the original document.

Usage

redraw_blocks(json, token_df, dir = getwd())

Arguments

json	filepath of a JSON file obtained using dai_async()
token_df	a token data frame generated with build_token_df(), reassign_tokens(), or reassign_tokens2().
dir	path to the desired output directory.

Details

Not vectorized, but documents can be multi-page.

Value

no return value, called for side effects

Examples

## Not run: 
redraw_blocks("pdf_output.json", revised_token_df, dir = tempdir())
