I'm reading the Dash documentation and can't seem to figure out if I can run WebGl (JavaScript API for rendering interactive 2D and 3D graphics within any compatible web browser without the use of plug-ins) inside the python platform. Html.script will not be executed but custom javascript placed in the "Assets" folder will be executed. I'm just not sure if this would be sufficient. I just want to add some pizazz the dashboard

I am trying Mongo Stitch to see if I can use it for some small web apps.
I created a simple application to play with some incoming web hooks and triggers, and called it MyApp. I am now expanding the application, and I have a purpose for it, so I'd like to give it a more meaningful name. However, on the Stitch Applications page, the only feature available in the app context menus is "Delete".
I expect I could do an export and an import using the console command, and editing the text files in-between, and if there is no other option, that is what I will do. However, it seems such an obvious oversight, I wonder if I have just not seen a menu option somewhere.
Currently, you cannot change it. Exporting it, changing the app name (and removing the clientAppId), and importing again should work. Essentially creating a new app.
I am playing with Highmaps to see how it works. I notice that in its examples, all the maps are loaded from this place:
https://code.highcharts.com/mapdata/
Questions:
Is the above link for production?
Would it be better to have a copy on my own server? If yes, where to download all the maps?
Yes indeed.
The mapdata is actually the official collection of maps by Highcharts.
As described on the official docs: http://www.highcharts.com/docs/maps/map-collection
You can simply load the maps using script tags, AMD or any other way of module loading, by including the files hosted on Highcharts's servers, for instance:
<script src="http://code.highcharts.com/mapdata/custom/world.js"></script>
All of the maps in the collection are also available in geojson format and svg.
In my projects, I'd rather download the maps and load them from my server's local system.
I don't believe it really matters, but since I did not expect these maps to change any soon, I could allow myself to have a copy of my own.
The reason I did it was since I used AMD (requirejs), and with that I could load the maps as modules.
Need help on rendering PDF using CGPDFContext. I am currently using UIWebView to display PDF but would like to perform much more operation rather than just reading like Highlight Text, Search PDF, Annotate PDF. Not looking for using any Framework or library.
Any help will be beneficial. For a start, code on how to render PDF using CGPDF and displaying it instead of using UIWebView.
PDF annotations are a rabbit hole. I've been working on them since 2010. The spec is thousands of pages. It's easy to get started but it takes forever to get right with all the PDFs and variations out there. Even a simple feature like bookmarks are harder than you would think.
To date there's no open source framework that implements PDF annotations. The above linked one can be a good starting point. If you don't have months/years to build something on your own, there are a few commercial options available - like PSPDFKit, available for iOS, Android and Web, which I am building.
We have a guide article listing the most important PDF spec documents.
Searching is another tricky topic. It's quite hard to convert the PDF text data to unicode. The Adobe CIDFont spec is a good starting point.
You shoud try VFReader, it is an open source project for rendering PDF files on iOS. It can be a good starting point.
I have an SVG file that I would like to display via Raphael (each svg file is a node in a tree I'm trying to draw, the actual connections of the tree will be made by raphael). I tried something like:
var vector_image = paper.image("test.svg", 50,50,50,50);
but no dice, seems only "real" image files like png or jpeg are accepted? I find this very strange as Raphael itself uses Scalable Vector Graphics.
Is there anyway (short of parsing the SVG files into javascript snippets and pasting them into the html document) to display existing SVG files using Raphael (or any other vector based javascript graphical engine?)
If parsing it will have to be, is there any easy way to do this, short of just manually scraping the files? I'm running this code on a Ruby on Rails server, so I'd like to avoid solutions outside this framework, if possible (I've heard of one PHP solution through this site...I'd rather code by hand than add another language onto this project).

It's currently not possible to display existing SVG with Raphael, and there are apparently no plans for the implementation of SVG editing (see this forum post).
As for alternative JavaScript libraries, a newer alternative is Snap.svg, which can load external SVG files via its Snap.load() function.
Wondered if anybody knows how customizable Flash swf files are made, where there appears to be a template swf that the user can then input some changes (eg text or image) and receives a newly-compiled swf file with their changes.
Some examples:
- http://flashfreezer.com/landingconfetti/index.html
Constraints:
- user receives a single output swf file that can be played with all their changes included. ie there is no reading from an xml file, or using Flashvars.
Been trying different things for a few weeks with no luck!
There are a number of ways, but generally the most common is to either use a SWF generating library (like PHP's) or through server-side compiling.
Normally, this will be a custom or proprietary library which uses the same language that the serve is running (and there are open-source libraries for this in PHP, Perl, Python, Java, C++... etc). The SWF is generated and served up with the appropriate headers so that the browser knows how to re-direct it. Often this will involve a pre-defined template which is then modified slightly for the new input. Only occasionally does this involve the manipulation of pre-generated SWF directly.
The other option is to have a command line call to the Flash IDE or the Flex compiler (and, technically, this can work for CS3 and CS4, though in a very nasty and hackish way) to generate a new version of the SWF on the fly. This is often slower, but it will generally yield a more finished feel to a product.
You could try Swiffotron. It can modify SWF files and do text replace type things on both text elements and in compiled actionscript.
Here's a swiffotron xml job file that does some text replacing.
And here's a swiffotron XML job file that modifies instances on the stage.
I didn't check the site, but the only way I can think of is to read the requirement details through flash (this can be done through plain html also) and then generate the AS files from their templates and compile them at the server side (using mxmlc or other compilers) and give back the SWF.
I get the impression that you're looking for SwfMill. SwfMill creates a swf based on an XML file that you create/define. You could use SwfMill on the server to generate a swf based on user input.
