From b8303e3860842cb3a84e3958fd28f4e1b3fd60c4 Mon Sep 17 00:00:00 2001 From: Sai Kumar <40134996+saikumarjetti@users.noreply.github.com> Date: Sat, 4 Jan 2025 23:31:13 +0530 Subject: [PATCH] Pdf to image custom page selection (#2576) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit # Description Implemented custom page selection for the pdf-to-image feature, allowing users to specify which PDF pages to convert to images. 1. Variable Renaming: Changed singleOrMultiple to imageResultType because it supports three options: single, multiple, and custom. 2. New Field: Added pageNumbers to accept user-defined page selections. This field appears only when custom is selected in the UI. 3. New Method: Added getPageIndicesToConvert to process and validate the specified page numbers. 4. Method Update: Updated convertFromPdf to handle custom page numbers, ensuring only selected pages are converted. 5. Translation Properties: Added two new English translation properties, custom and customPageNumber, to all language files with placeholder values. These will need to be translated into country-specific languages in the future. Note: If an invalid page number is provided (zero, negative, or exceeds page count), a single image containing all PDF pages is generated.
