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
)

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.
