Re: Scan Tailor Experimental no-DPI causing issues with pdfbeads and imagemagick

alraban, If you know what the DPI of your images is, you can input that DPI into the files themselves with a quick imagemagick command. If you are doubling the resolution with scantailor (output stage setting) and have a 1200 DPI final output: mogrify -density 1200 -units PixelsPerInch *.tif Of if s...

Re: Scan Tailor "Experimental"

Thanks for the return with some nice speed updates! I'm loving the new post-DPI Scantailor paradigm. It's easy enough to add the DPI info in afterwards if I want to. (For anyone wondering, just use imagemagick: mogrify -density ### -units PixelsPerInch *.tif) I didn't think I could be more impressed...

Re: Scantailor images to PDF for POD services on Linux

Since Scantailor-Experimental no longer works with DPI, a couple of changes are necessary for this. I just hacked out a little script that will do all of the work for you to get the images to print sizes. I've included two versions, one with a step for you to input the DPI and one for files with DPI...

Re: Canon Considering Withdrawing from Compact Camera market

I'm rapidly becoming the last person without a smartphone... It's disappointing that they are contemplating leaving that sector rather than just reducing the number of models. (Seriously, how many models do they actually need?) Perhaps it is inevitable, however, that the cheap camera market will be ...

Re: PPM tools from mhr

The first failure is that it's not calibrating properly. From what I can see, it's trying to convert JPG (case sensitive) to ppm files. At the end of the script, it deletes the PPM files, so the first thing I'd check is that it is actually making those conversions in the first place etiher by commen...

Re: PPM tools from mhr

Pablitoclavito, MHR has simplified the building process since there are now three different programs to compile. Just run the command: make That will build all the binaries. You can then put them where you want or you can run "make install" which will put them in MHR's default. If you run into other...

Re: Kindle Fire HDX 8.9" - using as a general e-Reader

That's a great size for a reader. I have a ten inch which is great to read, but is a little big to hold with one hand while doing so (and I'm 6'6"/198cm). It's also awkward to carry. My Dad has a seven inch which is great for portability and comfort but just too small to read pdfs with small text in...

Re: Add pages to project?

Just right click a thumbnail adjacent to the image that needs to be inserted. The menu offers you the option of inserting an image before or after the selected thumbnail.

Google Books Case Links

Since Groklaw is gone... If anyone has some interesting links about the recent dismissal, I'd be interested to see them. Now that the Author's Guld vs. Google has been dismissed and the recent Author's Guild vs. HaithiTrust ruling, a legal consensus seems to be emerging about digitization of printed...
