This plugin provides basic page positioning for raster and vector PDFs. For all pages or a selection of pages, the features include:
Page positioning using bounding box detection. The page data is then either positioned based on an offset from the corner of the bounding box to the corner of the new page size, or the center of the bounding box to the center of the new page size;
Resizing to a smaller page, by canvassing (i.e. masking from the page edges);
Resizing to a larger page size by repositioning the print area to the center or any of 8 other edge or corner locations within the new page size (canvassing);
Moving page content by specified horizontal and vertical offsets;
Includes page-positioning logic for dealing with double-sided pages.
