![]() In our test on Microsoft Windows we confirmed Evince was unable to open. It has been reported that the Windows version will only open PDF files. One notable glitch occurs when text is selected, the text becomes distorted. The DRM flag is ignored making Evince far more useful than Sumatra PDF or Adobe reader. The goal of evince is to replace the multiple document viewers that exist on the GNOME Desktop with a single simple application.Įvince currently supports PDF, Postscript, djvu, tiff, dvi, XPS, SyncTex with gedit, comics books (cbr,cbz,cb7 and cbt), and many more.Įvince opens PDF files into a well laid out reader. OCR works primarily on typeset characters and not hand written text.Įvince is a document viewer for multiple document formats. The level of accuracy depends on the quality of the scan and the font used. OCR will analyze the "image" of each character and match it to an electronic character-based file. To use software to convert a Scanned PDF into a Native PDF involves Optical character recognition (OCR) technology. For a scan of adequate quality it is possible with suitable software to regenerate the text of the document with Optical character recognition (OCR), and embed it in the file so as to make it searchable, subject to the accuracy of the OCR. However, the file size will be different, and it will not be possible to search for text. As far as a user can see it is just another PDF file, with a name and extension indistinguishable from any other a good scan may look exactly the same as a native PDF file, although a visually poor-quality file, often with skewed pages, gives away its nature. The scanned document internally contains a picture of the document, with no information about the text. PDF files created by scanning hard-copy documents containing primarily text do not have the same structure as a PDF file of the same document created directly. Only a native PDF can utilize all of the capabilities that the format lends to the reader software. A native PDF has an internal structure that can be read and interpreted. It is to stay that the text itself is actual text and not just part of an image. This is not to say that there are no images. This is due to a distinction of true text in the PDF from a PDF that is only images of text.Ī native PDF file will contain literal text as part of the structure, including information about the text. ![]() A native PDF file is superior to a scanned PDF file in capabilities, flexibility, and efficiency.
