pdf_page_batch: Batch Process PDF into LLM Messages

Description

This function processes a PDF file page by page. For each page, it extracts the text and converts the page into an image. It creates a list of LLMMessage objects with the text and the image for multimodal processing. Users can specify a range of pages to process and provide a custom function to generate prompts for each page.

Usage

pdf_page_batch(
  .pdf,
  .general_prompt,
  .system_prompt = "You are a helpful assistant",
  .page_range = NULL,
  .prompt_fn = NULL
)

Value

A list of LLMMessage objects, each containing the text and image for a page.

Arguments

.pdf

Path to the PDF file.

.general_prompt

A default prompt that is applied to each page if .prompt_fn is not provided.

.system_prompt

Optional system prompt to initialize the LLMMessage (default is "You are a helpful assistant").

.page_range

A vector of two integers specifying the start and end pages to process. If NULL, all pages are processed.

.prompt_fn

An optional custom function that generates a prompt for each page. The function takes the page text as input and returns a string. If NULL, .general_prompt is used for all pages.
