This usually just takes parts of a second and is useful to generate previews, galleries, etc. In the top-left corner a tiny, shaded on-screend-display shows the current cursor position as well as the color value of the pixel. The nice thing about it is that it can output position information for the OCR text in hOCR format, so that it becomes possible to put the text back in in the correct position in a hidden layer of a PDF file. Only at the end, for image thumb. Create an image for every page of the PDF; either of the gs examples above should work Generate hOCR output for each page; I used tesseract but note that Cuneiform seems to work better. This is easy to fix though.

In the future we will provide API documentation at this place as well as in-depth introduction and examples. I also tried specifying the resolution with a -r switch to hocr2pdf, but this did not result in any changes.

Even in low contrast images – here due to a rather saturated, dark background – the ExactImage library can still separate the barcode from the background. I wish there was a more complete solution; this is almost it!

TIFF x 24 bits, 3 channels. ExactImage includes a special mode activated with the command line argument -s, –sloppy-text, to group glyphs between whitespace to words which can help PDF viewers to produce better results while cut and pasting text: Due the lack of open source, cross platform and high quality barcode recognition offerings, ExactCODE developed an own, portable barcode recognition framework targeting highest recognition accuracy and fast processing.

As just working on the DCT coefficients is less expensive in terms of CPU cycles as the decoding and re-encoding process is skipped, it saving a lot time and additionally prevents new compression artefacts. Fast down-scaling is also implemented by Enlightenment’s EPEG library explicitly and we should mention that EPEG is slightly faster, but with cost to image quality – mostly because it does just nearest neighbor scaling of the residual scaling applied on top of the partial DCT decoding: I found its interface quite easy to use but I can’t seem to get it to detect the existing text layer The answer is not really Ubuntu-specific but I want to really thank you: Sign up using Facebook.
