Some PDF files with right-to-left fonts instead of encoding text as they should - from right to left - actually contain text stored in left-to-right (reversed) order. Notice for right-to-left readers (Hebrew, Arabic, and others). Use it if all other options produce an undesirable result.Īfter changing a line-breaking option in Application Settings you have to close the PDF Reflow view if it was open and reflow the text again. Treats all text on a page as a continious text stream. Useful with tables, where lines are close to each other, making it look like it`s a single paragraph, but all lines should be separated from each other. Inserts line-break at the end of every visual line. The same as the previous setting, but inserts a single line-break between paragraphs. Many Asian texts require a larger line spacing option to be on. Larger line spacing switch helps to determine which lines are 'close' to each other, and which are not. Useful for book-like or article-like formatting. Treats a group of close lines as a continuous text. Inserts two line-breaks between groups of lines that are distant from each other (considered as paragraphs). There are a few options in Application Settings that help break lines correctly depending on a text formatting style: Although we did a vast amount of testing and we`re proud to say that GoodReader handles most of the cases well, there`s still a chance of breaking words and lines incorrectly We have implemented a very sophisticated heuristic algorithm in GoodReader that makes guesses about word-breaks and line-breaks depending on letter-positioning on a page. Therefore many PDF files do not include whitespace or line-break characters, making it very hard to determine word-breaks and line-breaks. For example, PDF format allows us to specify the exact page coordinates of every single character. So there are many PDF files, which you can read in graphic mode, but extracting text from them may produce unexpected results. The PDF format allows omitting information that would allow extracting encoded text. The correct extraction of text is not always possible. PDF Reflow is a very experimental feature.GoodReader extracts the text as it is encoded inside PDF file, and it`s up to PDF creator to encode text paragraphs in the correct order, which doesn`t always happen. text extracted from a PDF page doesn`t necessarily have the same grouping order as you visually see it on a page.In such cases, reflowing may be possible.

However, modern, sophisticated PDF creation software may process the file with OCR (optical character recognition). a scanned PDF page is an image, and does not include actual text, so there`s no actual text to extract with PDF Reflow.Just tap where the back button is supposed to be, and you`ll get back to the original PDF page.

For your convenience, we have reserved the same zone of the screen for the same purpose when the navigation menu is off. You can quickly go back to the original PDF page by pressing the back button in the navigation menu. If Autoscroll is on and you`re turning a page, autoscrolling will continue after 3 seconds pause - GoodReader lets you catch up with the first few lines of text. Please note that when you turn a page in Reflow mode, the corresponding page in the original PDF mode is also turned, so two viewing modes are always in sync page-wise. However, all techniques for turning PDF pages apply to Reflow mode - you can turn reflowed pages by swiping, by tapping or by using Turn Page buttons. So you will only see the text from the current PDF page in Reflow mode. PDF Reflow is done on a page-by-page basis due to performance reasons. Use all reading techniques that you usually use for reading TXT files, including Autoscroll.
