A project I'm involved in has a specific requirement where a layer must be added on top of an existing SWF. The SWF is created by converting a PDF using SWFTools pdf2swf. This layer will be used to add interactive elements like videos or sound on top of the existing text content in the SWF.
My problem is, when I try to import the SWF into Flash Pro, it sort of breaks up and it's not possible to see the SWF or its elements correctly.
I've tried making the SWF a MovieClip symbol after importing and called its play() and gotoAndPlay(i) methods to no avail. Using an external SWF with a loader works, but the SWF should be internal so the whole project can be compiled to iOS and Android in one go.
Are there any other methods I could use to interact with a SWF and make it work inside my FLA project?
Your problem is not in Flash but the way you're transforming the pdf to swf. The default parameters of pdf2swf will export the swf for a previous version of Flash, 6 to be exact. So you need to explicitly set the flash version when converting to a later version so that you can import it in your timeline (assuming u're using AS3).
Use this config option:
-T , --flashversion num Set Flash Version in the SWF header to num.

I am trying to add three.js based 3D objects to a PDF page. It seems there are no direct exporters available to do that. So I am trying to do the below thing,
Convert the gltf/stl/obj files to U3D files
Add the .u3d file to PDF page.
I am trying to do the below process and I am not sure whether this approach is possible. It will be a great help if there is any support available to do any one of the below conversions. Also if you know any other possible approaches, kindly update me!!
Input formats output format
GLTF
OBJ U3D
STL
(any
three.js supported
3D formats)
Thanks.
There are few options available to export the three.js graphics to a PDF ( static content not a dynamic U3D assets)
Static contents
Get the rendered data from the three.js webGL renderer / canvas renderer using toDataURL("image/jpeg"), change the MIME type to JPG/PNG and add the resulting stream as an image to PDF ( this worked for me)
example - https://plnkr.co/edit/Ty8BZaDcflCJH5tH?preview
Like the above approach we can use three.js svgrenderer to export the renderer contents into a SVG data stream, which can be added into the PDF ( textures, mesh may not be 100% reproduced)
The legacy API - "threejs-pdf-renderer" can be used to directly export the three.js animations to a PDF. We don't need any other dependencies to create the PDF. But this is a legacy API which uses legacy three.js version, lot of effort needs to be done to make the API to be compatible with the latest three.js version.

Dynamic 3D contents
We can export the three.js animations into a U3D file (no direct support is available as for now), this U3D file can be directly embedded into PDF.

I'm developing a UWP app for tablet and i need to generate a PDF with data from SQLite. I need to do this completely offline because where I will use the app there is no connection. What could I do?
I'd prefer not to use paid libraries like Syncfusion and XFinium so I'm trying to find an alternative solution.
I tried with iTextSharp but unfortunately I can't find a good documentation to render a complex PDF or to export a Bitmap generated from a Grid Component to a PDF File.
Why not render your data into a webpage displayed with a WebView control? Then you can use any permissive licensed javascript library to generate the PDF.
If it hasn't changed much, then you can only send text back and forth between your WebView and UWP app, but that's workable. Your final PDF result can be read back as a base64 encoded string.
A very quick search found this one that seems easy to use and you can just download the source to put into your app:

I'm evaluating Fine Uploader compared to various other options, specifically JQuery File Upload.
I generally prefer the Fine Uploader approach as it's more lightweight, compared to JQuery File Uploader which has dependencies on Bootstrap and JQuery UI.
However it's important to be able to resize images: e.g., a user may select a large file from their camera and this may be very large - uploading the full resolution photo may take a very long time. JQuery File Upload doe this.
Additionally we don't have much use for very high resolution files.
If possible (I'm aware some browsers may not support this), I'd like to be able to resize images client size.
Is this possible?
Fine Uploader does not currently have any native support for image manipulation. This is a feature in our backlog, but we have not had many users tell us they are interested in this. This is one of the reasons why such a feature has yet to be implemented natively. There is a case, #707 that marks the start of native image-editing support for Fine Uploader. It is tentatively scheduled for 4.0.
However, you can certainly make use of FileReader and Canvas to resize the image. You can then submit this resized image as a Blob to Fine Uploader via the addFiles API method. At that point, the file has been submitted and Fine Uploader is ready to upload the item.
Essentially, the steps you would follow to handle this specific scenario, before Fine Uploader natively supports image manipulation:
Provide your own file input element(s) or make use of Fine Uploader's file/folder drag and drop support to get a handle on some files selected by the user.
Use FileReader to read the contents of the image.
FileReader will provide you with a URL for the image, assign that to the src attribute of an img element.
Draw the img onto a canvas element. This is where the resizing occurs.
Grab the URL of the resized image from the canvas element (canvas.toDataURL(...)).
Convert the URL to a Blob.
Pass the Blob to the addFiles API method of Fine Uploader.
The intent is to take care of most if not all of this for integrators such as yourself in the future by adding native image manipulation support to Fine Uploader.
Hope this helps.
I have run into a few dead ends trying to get an animated gif onto the clipboard in iOS using Titanium, so that I can then have the user paste it into an MMS.
I am considering trying my hand at creating a simple Titanium Module to get the image onto the clipboard with Objective C. This link has the code to do it.
My question is, can the Titanium Module access the file I have in my Titanium app's Resources folder? If so, I can just pass a path into the module.
If not, then I may need to pass the binary image data into the module (which probably won't work, since using a blob to put the image on the clipboard does not work)
Another approach might be to put all the images inside the module itself.
Our Silverlight application needs to show to the user previews of HTML pages it generates dynamically, so we want to use the WebBrowser to show these pages. The problem is that the HTML contains links to other local files such as images, flash objects, CSS and javascript files. The CSS and javascript could be placed inline in the HTML, but I haven't found a way to embed images. Something simple like this just doesn't work:
Creating the HTML file and the image file in the isolated storage is doable, but I can't get the path to the created HTML file to pass on to WebBrowser.Navigate(uri).
Reading the contents of the HTML file and calling WebBrowser.NavigateToString(string) will show the page, but not any linked images or scripts.
Linking to online sources is not an option as the application needs to work offline (i.e. out of browser) and performance would be much better if the images and flash objects were able to be cached locally.
So, is there any way in Silverlight of showing in the WebBrowser control a local HTML file that contains an image from the local file system, or is it impossible?
Thanks, sandeep agrawal
The only way to make that work is to make the Silverlight an OOB application, and then you can still only access the My* folders.
I heard that someone wrote a browser control that can be used without going OOB but not sure about that. This is a real pain, but a necessary one I guess.
