Hi folks, It would be great if I can get an official response and/or update in the documentation, so that we can forward the dependency proceedings internally.

Aguador, can you please link me the API documentation to convert 5 pages of PDF to PNG, one by one, or together in one go. Given 5 pages of PDF, LibreOffice API converts only first page to PNG. LibreOffice API, do not have any Page Exacter or indexer where [i]th page of one file containing 5 pages of PDF can be extracted. > > Best, > aguador Why are you top-posting a new post instead of responding to what aguador wrote? Please learn email etiquette (and bug reporting etiquette!) And why are you ignoring the suggestion, given that is what is already posted as a workaround in the bug report you linked to? If it won't work for you, you need to explain why. Dave, Aguador: CC’ing the person who responded with a textual workaround which seems to be inefficient and is non documented in LibreOffice API for further explanation or a link to API endpoint. Dave: Can you please link me to LibreOffice API documentation to convert a multi-page text file to single page or multi-page PNG. If it’s not possible, do you think there should be proper documentation for the same. Devs, maintainers: One workaround to convert a multi-page text file to PNG is to extract each page text and store into buffer streams (JAVA programming language concept) and then write that text as PNG. For a huge file, or a on-the-fly stream of files, say, 10KB to 100KB, this process, would be highly inefficient, if not done by LibreOffice API using machines System calls. Folks: is there any documentation to convert a multi-page text to PNG in LibreOffice API? In other words, is there any such API end point for the same. It would be great, if we can document this behaviour of LibreOffice API of Converting only first page of multi-page text file to PNG and NOT converting ALL pages. Thanks so much!
