Re: Make a djvu file and add ocr [mixed text/image tif encoding to DjVu file]

Using Gimp v.2.8.18, DjVu Small and DjVu Imager to make a mixed text/image DjVu page from a single .tif image output by ScanTailor Advanced v.1.0.14. My preliminary notes for converting to DjVu one or two isolated tif files of mixed text/image. Simulating the "ScanTailor Featured" export tif split b...

Re: Make a djvu file and add ocr [metadata injection]

At the weekend I explored two aspects of DjVu files: 1. injecting metadata into the file; 2. using Gimp v.2.8.18, DjVu Small and DjVu Imager to make a mixed text/image DjVu page from a single .tif image output by ScanTailor Advanced v.1.0.14. I set out here the outline notes of my initial fumbling e...

Site certificate / YouTube channel

Possibly an inane question but in the last week or two I've noticed my bookmarked url for DIY BookScanner http://www.diybookscanner.org/forum/index.php started throwing Firefox invalid site certificate errors* so I haven't visited in that time. Deleting the preceding www. today takes me here without...

Re: bitmaps into vector graphics: cr2v.exe - anyone have it?

Thanks very much, I'll give it a test drive. Incidentally I see Inkscape v.1.0 is out as of 1 May: https://inkscape.org/release/inkscape-1.0/ My interest in these as well as in potrace springs from the probably misguided idea of exploring whether any can produce from ScanTailor output greyscale or b...

bitmaps into vector graphics: cr2v.exe - anyone have it?

I was briefly experimenting with potrace and came upon references to the early, free version of a similar (MS DOS) program, cr2v.exe which apparently used to live (nearly 20 years ago) at http://www.celinea.com/demos/cr2v.zip - but the link is to another location which appears not to have been saved...

Re: Make a djvu file and add ocr: DjVuToy; TiffDjvuOcr; CuneiDjVu

Hah, it's always the way: post something then find the more elegant solution. In the particular circumstances I since found that changing the filename of the target DjVu (which included an apostrophe) to x.DjVu (for example) and re-running the write command in HandyOutliner successfully wrote the bo...

Re: Make a djvu file and add ocr: DjVuToy; TiffDjvuOcr; CuneiDjVu

This doesn't really merit a reply-to-self but absent a visible means of editing my previous post to add this, here goes... 1) writing to DjVu (or pdf) the outline/bookmarks output by STDUViewer: having tested a little further it seems this almost universally, maybe even always, can be fixed easily i...

Re: Make a djvu file and add ocr: DjVuToy; TiffDjvuOcr; CuneiDjVu

Another way to create an outline/set of bookmarks for a DjVu file without FineReader and without needing any intermediate PDF format is manually, per bookmark (easy for a small number of bookmarks): 1) open the DjVu file in STDU Viewer: http://www.stdutility.com/index.html 2) in main pane select tex...
