Correct sideways or inverted page orientations and prune obsolete pages with one-click page action controls.
All canvas rendering and pdf-lib document re-ordering operate entirely in client browser RAM without server file storage.
Visual page organization relies on a dual-engine architecture combining PDF.js for fast client-side canvas rendering and pdf-lib for indirect object manipulation. When a PDF is loaded, PDF.js extracts page viewports at a 0.25 scale and renders thumbnail previews into HTML5 <canvas> elements.
During user drag-and-drop interactions, DOM elements in the thumbnail grid are re-sequenced. Page rotation adjustments update the card dataset angle (data-rot) while applying CSS canvas transforms for real-time visual feedback.
Upon compiling, pdf-lib iterates through the active thumbnail DOM order, deep-copies source pages via newDoc.copyPages(srcDoc, [pageIdx]), applies rotation angles with copiedPage.setRotation(), and appends the modified page trees into the destination PDF document stream in local RAM.
