Output Background Color for Mixed & B/W

I've noticed that when using Adobe Reader to view ebooks with inverted colors (white text on black background), none of my ST-generated images invert their backgrounds. (They stay white). This only occurs on ST-generated ebook images. Other PDFs unaffiliated with ScanTailor production invert normall...

Re: Sony α Nex-5: Dual Camera-Fire on a Single IR Remote

Dan, That link is dead. But I have a couple of places to get the spillters.

Just curious: will silicone or hot glue will disrupt the bridge If I adhere my cables in some manner to the sensors, or do the cables just need to be 'close'?.

Re: Vectorization

Hey, Spam, you know I do notice that Acrobat Pro is a memory hog, and should really run alone on the desktop. No browsers open etc. I run the ClearScan package overnight; and now that you mention the instability of it's batch processing of PDF larger than 50 pages, I can reaffirm your issues with th...

Re: PDFMaker 0.2 - help beta test!

A good mixed-bag of media in the PDF will be a great to try. No OCR on this yet, correct? Also: Perhaps if there's a way to send different optimal compression levels with their specs; maybe the original uncompressed. Take your time on this, it's kind of a tall order to ask someone to do this pro bon...

Re: PDFMaker 0.2 - help beta test!

Hi Misty,

I was curious if you could send me a small-sized copyright-free PDF made from PDFMaker where I can test sending the whole doc in Illustrator LiveTrace as a complete vectorization test.

I suppose I'd like to try this on a compressed ebook with B/W line of art material & text.

Thanks.

Re: [Scanner-Build] Ram-Book (1 cam, 2 pages, 3rd cheap)

Once the ST dewarp feature is implemented automated, yes, you will in theory be able to split the image down the center and then keystone-correct within a single workflow. I think there is a slight communication barrier. When you refer to perspective , I believe what you are referring to is keystoni...

Re: [Scanner-Build] Ram-Book (1 cam, 2 pages, 3rd cheap)

Well, you're dealing with double keystone angles at 45 degrees opposing each other within a single image. So of all things important, correcting this double keystone is actually a prime concern. Maybe you're not describing what it is you're after. You're setup doesn't suffer from warping either (if ...

Re: [Scanner-Build] Ram-Book (1 cam, 2 pages, 3rd cheap)

well, I like the auto -splitting part of ScanTailor :) Actually I think all that is necessary is automatic correction of perspective distortion of dual-pages. Or just set it manually once for both sides and then apply it to all pages. It really doesn't have to be all that precise, the straighten li...
