Using the method render_preview from render_preview.py you can transform a LaTeX document (stored in a file) into a PNG image. To increase the resolution you can increase the density parameter.
You can simply run boinc_result_to_tex.py with a given BOINC result file as a parameter, e.g. python3 boinc_result_to_tex.py RNM_general_001574
You can run the get_boinc_results.py to update your local boinc_results folder with the current results available on the server. Then, you may run generate_boinc_result_previews.py in order to create preview PNGs for the BOINC results you have, using the BOINC result to LaTeX and LaTeX to PNG transformations.
