I was looking for a quick way to generate UML like documentation for my project when I stumbled across the Quick Model menu item in Xcode. I was wondering if there were a way to export these diagrams in a non-platform-specific file format like png or pdf? Basically I want to take some quick visual diagrams (illustrating component relationships) of some of the major classes in our project to management. Does anyone know of an idea?
File > Print, and choose Save to PDF from the gear menu in the Print dialog. Works in nearly every Mac OS X app.
#testing GraphicConverter allows you to open PDF's or files saved to iPhoto and then converted to PNG and crop them with precision to then rejoin in a bigger file. It's quite tedious but works. OmniGraffle should have a CoreData importer but it's not in the Standard version.

Is there any way to create and display music notation inside of a codenameone app?
For Java generally there are some libraries like for example JFugue that let you write music inside a program. Maybe also display it, i didn't try that out.
There is lilypond, which would work in a desktop environment if you were able to run it to make the pdf after generating the file itself.
I wrote a small app in Android Studio and had to write my own music notation logic and drew it with the help of png files on a Canvas. That worked okay for small musical examples of a clef and around 2-7 notes.
Now i want to do something similar in Codenameone and display at least a clef and some notes inside the app (maybe as an image) - they have to be generated with some random element while the program runs.
It would also be great to be able to write and show more than a few notes, displaying it somehow and maybe also with the ability to have it as a pdf file later.
Is it possible to use something that already exists?
Thanks a lot!
I have a PDF (created from Word) for a game I wrote for an old 8-bit computer, and I'd like to embed the code for that game (binary, less than 32k) into that PDF. This way, my emulator can load the program by reading the PDF, and the two can be stored and shared in one file.
You could call this a form of steganography.
I know a PDF has a tree structure and uses ASCII to define its components; is there a way to add inert, "orphan" elements that won't cause problems for PDF readers? I think that would be the easiest way to do it. But I'm not sure how to do it.
The simplest solution would be to use a document attachment or a file attachment annotation.
Most PDF tools that are available support these features as they are pretty basic.
This is not strictly a programming question, but it's related to programming task I need to perform this in order to make an iPhone app.
I have a PDF file with a large image (say, a campus map) which I want to store as a PNG image to include as resource in the app. The image I want itself is much larger than the screen area (a lot larger, about 4000x4000 px). So I cannot just take a single screenshot of the PDF and save it as PNG. The only way I know to accomplish this is to take a number of screenshots of different parts of the image and manually stitch them together in an image editor. There will be 8-10 images to stitch together, if not more.
I wonder if anyone knows a more efficient way of doing this? Acrobat PDF reader does not allow this. Are there any tools or tricks in either Windows or MacOS I can use? Googling this did not bring anything that works.
It would also be an option to use the PDF directly, iOS has pretty good support for reading PDFs, see the ZoomingPDFViewer sample code from Apple for an example.
As for your actual question, I'm not sure if there are existing tools that do exactly what you want here (though I'd guess there are), but it would also be pretty easy to make a small Cocoa command-line tool that converts a PDF to a number of bitmap tiles using Core Graphics.
You could use Ghostscript to convert your pdf to a png.
A command like
gs -sDEVICE=png16m -r600 -o my_Map.png my_Map.pdf
would provide you a png from a pdf image.
I'd like to make my app to open a specified PDF by an external app of the user's choice on the iPad. How can I do that? Or, is there any open-source PDF reader framework available so that I can put it into my app?
My situation in more detail:
I'm thinking of porting to the iPad from OS X / rewriting from scratch for the iPad an app which manages lots of PDFs (journal articles, etc.), but I don't want to write the PDF reader part, because there are many good ones already out there; I don't want to reinvent the wheels.
(You might say you shouldn't reinvent pdf management apps, but I'd like to make one as a front end to SPIRES, and there isn't one so far.)
As the app would be a front end to a serious reading activity, UIWebView's pdf capability is not enough.
Also, users of my app would have various preferences which app to use.
That's the background behind my question. Thanks in advance!
Here's my self-answer:
Use UIDocumentInteractionController. See this Apple doc.
The problem now is to find a way to choose programmatically exactly with which app you open a document, when multiple apps are available to a same file type.
Its not that hard to view PDFs without a UIWebView. You use some Quarts 2D drawing but a large majority of the work is done for you. You mainly have to choose how you will flip pages, and do pinch to zoom.

You aren't able to search inside of PDF files. You can't access the text. You could do annotation, but it would be a hack at best.
I am working on generating a document for printing. It should use a specific TTF font and everything must be printed with vector graphics (for quality). Some of the text should be replaced automatically (e.g. current time). Also it should include a custom-generated EPS image with a chart.
Ideally I would like to have some kind of document template where the text could be replaced easily, and it would be nice if it could import the image through path. But I am not sure which format could be good for this. Best I can come to think of is LaTeX, but I don't like that it's a lot of manual work to use it with TTF... any other ideas?
By the way, I am using OS X...
Memoir package is very flexible for your special layouts.
Xetex uses your system fonts (Installed together with TexLive).
You could blend most of those elements to an EPS using imagemagick or gimp script-fu
There are several products out there that will build you a PDF programmatically. I've only used the Coldfusion Report Builder myself and that may not be practical/affordable for your application. If your budget allows I'd look into a commercial reporting product. I know Adobe have several that will generate Flash, FlashPaper or PDF output.
