I have a project documentation written in ASCIIDOC with editable PNGs and
I would like to create a link in my documentation that opens a local file directly in draw.io (diagrams.net).
Something like https://app.diagrams.net/file=/home/alex/test.png.
or https://app.diagrams.net/data={HEX DATA OF PNG}
My first stop was in the documentation: https://www.diagrams.net/doc/faq/supported-url-parameters
but I couldn't figure out how to transform my editable PNGs for the data parameter nor how to instruct the application to automatically open the upload dialog.
Any advice is greatly appreciated.

I've been searching for several days now a way to embed a data file, which is in text format, inside an app I'm trying to build in Adobe Flash for Adobe Air (for Android for now). The text file has a lot of data I want to use in my app, so I want to embed it inside the app, so when the app launches I can use it.
I've been reading about how to read and write text file in Flash and Adobe Air, but couldn't find a way to add this file to be part of my app. The Adobe Flash Library that is used for saving various assert (File > Import > Import to Library), doesn't support text file (only image, sound, video, and other graphic formats). Is there an other way to add a different (i.e. Text) file to the app?
As a last resort, and to help me proceed with the implementation, I tried manually copying the file to the Android "Documents" folder, and reading it from the app using this:
var myFile:File = File.documentsDirectory.resolvePath("MyText.txt");
var fileStream:FileStream = new FileStream();
fileStream.open(myFile, FileMode.READ);
var fileContents:String = fileStream.readUTFBytes(fileStream.bytesAvailable);
This worked on the PC when testing, but on Android it couldn't find my text file. I placed it in "My Files > Internal storage > Documents" (on Samsung phone). Is there a different "Documents" folder I should use to be found by documentsDirectory.resolvePath() function...
Anyway, as said, this was last resort solution, and much less preferred, because I don't want the users of my app to need to copy internal data files for the app to work, it should be part of the APK... So embedding the text file somehow inside the app is a much better solution, but I couldn't find a way to do that.
Thanks Organis for your answer, I didn't yet try it but I guess it should work.
I found another answer few hours ago, and will share it now, in case someone else encounters this problem.
You could embed a file from the "Publish Settings" dialog, then going into "AIR for Android Setting" (small wrench icon). On the "AIR for Android Setting" under "General" tab, at the bottom there is "Include files". You can click the [+] icon and add any file you want.
From the code you can access this file using standard file read method, using URLLoader & URLRequest functions and Event.COMPLETE to get the data when the file finishes loading.

Hello I'm making a website and I want that an user can edit some of the texts content in the website, clicking a button "Save" and the changes are permanent.
I suppose I have to put all the text in a database instead of keeping it in html code, but this will slow down the website loading performance.
Is there a library to easily achieve this functionality? Pheraps changing html code instead of acting on the database.
You have to read the file content and load it into a form in a textarea or WYSIWYG and after submitting the form, put the changed data back into the file. The codes for loading and saving data, depends on programming language. check the documentation for opening and saving the file in PHP here.

Is it possible to add additional file types to be recognised as images and thus trigger automatic creation of an image view when a resource is uploaded?
SVG files will preview in CKAN, but we have to manually add the image view e.g.
https://datastore.landcareresearch.co.nz/dataset/novel-yeasts-from-new-zealand-forests/resource/3812ee6b-dd45-45c9-b425-6a18375e5727
With text (for example) we can specify file format extensions to recognise as text and automatically create a text preview (ckan.preview.text_formats...). Is there an equivalent for images?
Thanks
It would only be possible by modifying the source code for your instance:
https://github.com/ckan/ckan/blob/master/ckanext/imageview/plugin.py#L9
Seems like a great idea to have the image view on a par with the text view in this regard, so I made a pull request:

Is there a way I can render a 3D model (in .dae, I'm using SketchUp) into a x3dom? I looked up online, but can't find the way.
Hope someone can help.
You can load the COLLADA file in the VRML/x3d viewer bscontact from Bitmanagement (http://www.bitmanagement.com/en/download) and then "save state as" x3d, x3dom.
Or you can use the InstantReality framework and use aopt.exe to convert the collada file into x3d or in x3dom.
I have been working with Vaadin charts during this week and I found a problem that I cannot solve. I need to send several charts to a PDF generation (using iTextpdf) and I could do it using SVGGenerator. The main problem is I cannot use this solution because the final laptop doesn't allow any installation, and Phantomjs is required for SVG Generator (no add-on can be installed neither). I tried to find a different solution to convert the chart content into file or buffer that I can manage, but I think I have been reading so much posts and I am not able to distinguish the solution.
So, I will try to clarify basic questions first:
a) Is it possible to manage SVG Generator without any installation in the laptop?
b) If not, is there a different way to convert a chart into an object which class could be managed to insert it into a PDF?
I can assure you I tried to read all documentation in this forum and official Vaadin forum related to this topic but I couldn't find any solution. I don't want to seem lazy, I only want to avoid spending more time and clarify the maining pre-conditions to solve this issue.
thanks in advance for your time and help.
Kind regards,
David.
You can take a screenshot of your chart and append it to pdf:
Screenshot screenshot = new Screenshot();
screenshot.setTargetComponent(myTargetComponent);
myChartLayout.addComponent(screenshot);
//when complete
screenshot.addScreenshotListener(new ScreenshotListener() {
public void screenshotComplete(ScreenshotImage image) {
//do something
}
});
//take screenshot
screenshot.takeScreenshot();
You will not be able to render a Vaadin Chart without a web browser engine of some kind. That's what PhantomJS provides. If you have a full-blown web browser at your disposal, though, you can grab the SVG markup manually from there; it's just a bit more difficult to automate. This works in Chrome:
Open your Charts app in the browser
Open the JavaScript console (Ctrl/Cmd + Shift + J)
Type something like this: copy(document.getElementsByTagName('svg')[0].outerHTML)
Paste the contents of your clipboard to a new text file and save it as an SVG.
You don't need to install phantomjs, just bundle its binary along with your web application (Reference). I did the same thing with my Amazon AWS deployment and it works just fine.
