A4 PDF FixSkew
is a simple tool for correcting the alignment of scanned PDF documents. It can correct the alignment of multiple PDF documents
at once. It is also not based not OCR (Optical character recognition) technology, so the readability of the documents is not an obstacle for successfully correcting the alignment.
User interface is simple, consisting of main window, with a few buttons and a list. When opening the tool, we must first select PDF files, that we want to be processed. We can add them separately or we can select the entire folder and import them automatically.
Before processing the files, we have the option to select skew engine we want to use, if we want temp files to be compressed or uncompressed, and we can also add a prefix to output files. First skew engine gives us more options, such as resample width, angle range for scanning, angle precision, and edge detect option. Setting resample width can enhance performance, while setting low values for angle range for scanning, can enhance performance and accuracy. In second engine, we can specify the treshold in percents.
So, if you have scanned some documents and created PDF files from them, and the pages are not aligned as they should be. This is the program that may come handy, to quickly fix this problem.
