I do plan on adding some rudamentary tools for deskewing, but they are going to have limitations. First, if you use it on a PDF, it's going to have to rebuild the document, because the PDF specification only supports rotating by 90 degrees. So this means I have to extract the images from the PDF, rotate them slightly, then rebuild the PDF from those images. Unfortunately, the PDF library I use to generate PDFs does not support compression. So this means that a file that was highly optimized and compressed will suddenly become larger and slower after deskewing. So I would definitely recommend making these kinds of modifications outside of MobileSheetsPro, preferably at the time when the images are scanned so that the PDF is constructed with the properly aligned images.
