Output shape

a single PDF file with multiple original pages merged onto each page per the layout configuration

Input PDF can be supplied as binary data or by referencing a server-side file ID. Layout is configurable with either a preset number of pages per sheet (DEFAULT mode) or explicit rows and columns (CUSTOM mode). Margins, orientation, reading direction, and optional borders can be set.

Examples

Example 1: Merging an input PDF binary with 4 pages per sheet using default mode, arranged by rows with LTR reading direction, no borders.

Set 'fileInputBinaryProperty' to input field name; 'mode' to 'DEFAULT'; 'pagesPerSheet' to 4; 'arrangement' to 'BY_ROWS'; 'readingDirection' to 'LTR'; 'addBorder' to false.

Example 2: Merging a server-stored PDF file by specifying a file ID with a custom layout of 2 rows and 3 columns, landscape orientation, with borders of 2 points.

Set 'fileId' to target file ID; 'mode' to 'CUSTOM'; 'rows' to 2; 'cols' to 3; 'orientation' to 'LANDSCAPE'; 'addBorder' to true; 'borderWidth' to 2.
