Parse figure references from a LaTeX slide file

Extracts figure paths referenced via \\includegraphics, \\image, \\imageC, \\imageL, \\imageR, and \\imageFixed commands.

Usage

parse_slide_figures(slide_tex_path, prefix = "figure")

Arguments

slide_tex_path

Character. Path to a .tex file.

prefix

Character. Directory prefix to filter for, e.g. "figure" (default) or "figure_man".

Value

A character vector of figure basenames (without extension), as referenced by the slide. Duplicates are removed.

Details

By default, returns references to figure/ paths (skipping cross-chapter ../ references, ../../slides-pdf/, etc.). Set prefix to extract references for other directories, e.g. "figure_man".

Note: This uses regex on .tex source and cannot resolve dynamic paths (e.g. \\foreach loops). For more robust detection after compilation, use audit_chapter() with method = "fls".

Examples

if (FALSE) { # fs::dir_exists(here::here("lecture_i2ml"))
parse_slide_figures("lecture_i2ml/slides/evaluation/slides-evaluation-train.tex")
}
