I am an absolute newbie as far as Powershell goes. I found a script here - https://www.litigationsupporttipofthenight.com/single-post/2020/04/19/powershell-script-to-count-words-lines-and-characters-in-multiple-pdfs - that I thought was exactly what I was looking for but when I run it, it seems that it sees my image based pdfs as just text files and says there are thousands of words/characters in them. I have a feeling that I am missing something.....I see various forum postings on the web regarding itextsharp and searching words in pdfs (no idea if this is it or not)?
Hoping someone can point me in the right direction (a specific example of this on the web somewhere) would be very much appreciated.

Not sure this is the right stackexchange site but seems to be the place with the most question about Alfresco I can find so here goes.
Have Alfresco Community Edition 4.2.d installed on a RHEL5 64bit box (mainly default install bar using MySQL as a database locally). Uploading PDFs to the documentLibrary is fine and thumbnail previews and flash previews are generating. If the PDF has been processed by ABBYY OCR (which we have running on a separate server and is used to OCR scanned PDFs) then the flash preview generates fine but the thumbnail is incredibly dark and looks as if it has been attacked by a can of spray paint.
I initially thought it could be a ghostscript issue but have updated that to 9.14 and still getting this issue. I have also tried playing around with ImageMagik but I can't get a nice clear thumbnail to generate. I am guessing it is a switch in the convert command that Alfresco is using but I am struggling to work out a combination of switches that will work and then where Alfresco would store these parameters. Or indeed what switches are currently being used.
I was wondering if anyone had seen this behaviour before with ImageMagik previews in Alfresco 4.2.d? It seems something unique to PDFs that have been through the OCR process so I am guessing I will need to create a separate transformation for them at a later stage.
EDIT: So it was suggested that a later version of ImageMagick and GS should resolve it. I have therefore installed GS 9.14 and IM 6.8.9-0 (both compiled form source). Running the following from a command line:
convert /root/test1.pdf[0] /root/test1.png
results in a crystal clear image thumbnail preview. Thinking I was on to a winner I have amended the following lines in alfresco-global.properties to point to the system location of GS and IM:
img.root=/usr
img.dyn=${img.root}/lib
img.exe=${img.root}/bin/convert
img.gslib = /usr/local/share/ghostscript/9.14/lib/
and alfresco loads. However the thumbnail preview generated by Alfresco using the new version of IM and GS does not result in nice clean previews.
I am guessing that Alfresco is passing some command line switch during the conversion that is undoing the good work of the later versions of these programs. Does anyone know where the switches for thumbnail creation might be stored in Alfresco?
I guess it's related to transparency and default background black. I didn't find an easy way to add the required parameters to the script except to register a new transformer supporting more parameters like:
-fill white -opaque none

How do I grab a thumbnail screenshot of many websites?
I wrote a script using perl mechanize to login and fetch a page. How can I "print" that page to "pdf" directly from my perl script? I'd like to save a snapshot of how it looks in the browser.
I can get the html using $mech->content();
Check out wkhtmltopdf - there are variants for PDF and images (PNG etc). It's basically a command-line tool wrapping the webkit html engine. Works quite nicely, and it's cross-platform too. Whether you can get it past your login form will depend on how the target site works.
There's a number of CPAN modules to convert HTML to PDF. Feed any of them the content from Mechanize.
The $mech contain plain html so you can't just print it. Check this thread: How do I grab a thumbnail screenshot of many websites?
I need a tool to programmatically convert epub files to a series of images. The output should look like screenshots taken on a canonical device (for this application, an iPad). I haven't been able to find any tools that do something like this.
So what I'd really like (1) is a tool that does that. But assuming that I'm correct that no such tool exists, is there (2) a library (preferably a Perl module, but I'm not that picky) that will read and render ePub?
Obviously, rolling my own I could combine tools for unzipping, reading html, reading xml, putting everything in the right order, and rendering html within certain constraints. Though I'd rather not do that, and if that's the only option I'll have to go on to look for a tool that will do the last part of that or I'll have to create that too.
Any leads on (1), or failing that (2)?
Apologies if what I'm about to type is just crazy-talk on my part--in fact, I'm pretty sure it is--but perhaps something like this might work and I'm kind of interested in knowing how well it might work for you:
Use Frank (https://github.com/moredip/Frank) to control the iOS Simulator on a Mac. Program it to open up the EPUB docs you need.
All you need then is something to automate the taking of the screen shots. Obviously, these will look like the EPUBs are being rendered in an iPad (or an iPhone if you wish--the iOS Simulator does both, of course).
Automating the screenshots can probably be done with AppleScript, although the hard part might be getting it to talk to Frank. Worst case, you can tell Frank to pause for 5 seconds after it loads each page and tell AppleScript to take a screen shot every five seconds. That sucks, but if you're desperate, it will get it done. It's also possible Frank can somehow make the screenshots happen--I haven't used it enough to know.
Pandoc can convert from EPub to LaTeX (and therefore to PDF) or to any number of other formats. Conceptually this should be a type (1) solution.
depends on your definition of "look like" - do you want the user-chrome or just the epub rendering for a given screen size.
I would check out the various epub readers for your platform of choice, size the window to your preferred dimensions, and then just "print" the epub to a virtual printer that outputs to image files - on windoze I use imageprint.
You could easily make a "frame" from an iPad product shot and place your screenshots within that - only thing missing would be as I said the user chrome.

I am trying to import paths from a vector drawing program into the ios environment. I would like to get them into CGpaths or UIbezierpaths. I am most interested in importing paths from adobe illustrator. The best way seems to save as an svg and then import.
I have found some resources for parsing exported SVG files that describe the paths. However, everything I have found only deals with absolute paths and not relative paths. The path below has capital C's and lowercase C's. I know how to parse the capital C (absolute paths) but I have no idea how to parse the lowercase c's (relative paths)
I am looking for help with writing a parser for importing svg files into ios/cocoa. I think there is a big need for this judging by searching the internet for weeks.
Here, is an example of a path I would like to import into my iphone app. I am not looking to import the image, I want the path itself. So, I can manipulate it. Any help would be much appreciated.
x="0px" y="0px" width="320px" height="436px" viewBox="-1.4 -0.5 320 436"
d="M294.1,116C290.6,1.4,170.9,0.4,159.6,0.5
C148.3,0.4,28.7,1.4,25.2,116c-3.7,120.3-49.6,141.4-5.9,233.9c41.3,87.4,130.7,87,140.4,86.7c9.7,0.3,99.1,0.8,140.4-86.7
C343.7,257.4,297.8,236.3,294.1,116z
If this was all absolute paths I would be able to solve this now. It is the relative (i.e. lowecase (c) paths) that are really confusing me.
Alright folks, if you're willing to pay for it. This tool will solve all your issues. You can import svg or psd and will produce the code for you. I've used it and it is amazing!

There's an open-source SVG library in ObjectiveC, specifically for iOS (and OS X, although the OS X build is a bit behind):
https://github.com/SVGKit/SVGKit/
(I've been using this on iOS projects since the start of this year, it works well)
2018 update: OSX support is now in, and SVGKit renders most SVG's fast + accurately. On the downside, advanced text features aren't all supported (e.g. yes to gradient-fill, but no to complex text-layout).
As of early 2012, it's not a 100% implementation of the SVG spec, but there's a lot of people working on getting it there.
If you're willing to do some translation from JS to ObjC, then you might find this project helpful:
https://github.com/thelonious/svg-2d
Particularly, the path.js file which includes a parseData method, taking care of relative and absolute path commands.
https://github.com/thelonious/svg-2d/blob/master/shapes/path/Path.js
I should mention that I wrote this code years ago, but I have translated it to Java and C# and have used in professional products (can't share that code, unfortunately) and it seemed to work well in those environments as well.

Sketch 3 on Mac App Store is good at editing (can be better than PaintCode) and then exporting as SVG to PaintCode.
To get from PaintCode back to Sketch save as PDF and imports ok

Make sure canvas size in both is set to the same and in your views bounds else youll need to scale the context.
SVGgh contains a class, SVGPathGenerator, which will convert an SVG path to a CGPathRef:
+(CGPathRef) newCGPathFromSVGPath:(NSString*)anSVGPath whileApplyingTransform:(CGAffineTransform)aTransform;
You can use it to do exactly what you request.
[Swift 3 Update] If you want a pure Swift solution. My (in progress) Scalar2D library has an extension on CGPath that creates a CGPath from an SVG path.
This solution is a straight conversion of an SVG path string to UIBezierPath. It worked great for my app where I had to draw the united states as a UIView.

Oneliner that adds an SVG to an NSView:
addSubView(SVGParser.svg(FileParser.xml(~/Desktop/test.svg)))
