Flex :: Convert A PDF To A Jpg?
Jul 20, 2009
In a Flex/AIR application, I need to create snapshots (like big thumbnails) of local PDF files (one per page, if indicated).Ideally, I would like to do it all on the client side (PDF is a public specification, albeit a REALLY COMPLICATED one).I have read about an "Adobe plug-in" but I cannot find a specific piece of software that makes the HTMLLoader.pdfCapability report anything but ERROR_CANNOT_LOAD_READER. I hope to load the PDF and then move the bitmap data to an Image in order to save it.

Using the ArcGIS Server Flex API, is there a way to convert mouse coordinates on the screen or the a map control to spatial coordinates in the map? It seems like there's functionality to convert map points to screen points, but a function for converting in the other direction seems weirdly absent.

But is there a good way to convert ArrayCollection to XML.

I have a flex component that is using mostly mx and actionscript code. I am using it fine in my AIR application, however, I need to be able to use certain Air libraries within this component, so I need to make it Air 'aware' or compatible. For example, I need to get a reference to the current active window, so it looks like I need to use NativeApplication.activeWindow. But when I type this in to my component actionscript class, it does not know about NativeApplication. So it seems I have to do something to that project to enable Air classes, unless there is another approach?

how to get the charCode from the character but I cant seem to find out how to get the character from the charcode.
Basically I am I am listening for the KeyDown event on a TextInput.
I prevent the char from being typed via event.preventDefault();
Later I need to add the text-char to the TextInput.
I can get the charCode via event.charCode so if I can turn that into a string I can save it for later user.
Why I need it
Basically I am making a TextInput, that that I can set to display default text in it. When A user types into it, I want to remove the default text first then add the user typed text.
Currently I am either removing it all, or ending up with both.

I'm giving users the ability to upload an image to my Air app, then displaying this image in an image control. But I need to allow for PDF uploading in the same manner, so I need to convert the PDF to an image. I only care about the first page of the PDF they upload for now. What I'm doing is:
1) User browses for a file with the file reference control
2) User chooses the image or PDF to upload
3) I encode said image to base64 and store it
4) I then load from that base64 with something like:

how to convert a file I have on my server (pdf/excel/ppt) to a ByteArray. The reason I want to do this is to display the dialogue open/save as to the user and I must set the Content-Type to octet-stream. The dialogue shows fine with just navigateToURL() but for pdf's it is the user's local browser setting. For a URLRequest I must set the data as a ByteArray. I'm trying to use the code located here:

I want to create a board class from canvas, which will allow to track click position on it in coordinates like A2, where A...D is Y coordinate in some scale and 1...3 is X coordinate [URL]What I want to create is a kind of convertor from canvas localX and localY to my new coordinates like A2.I am thinking of implementing if condition this way if (0.4 - x*size(from 1-3 here)/canvas.width <= X <= 0.4 + x*size(from 1-3 here)/canvas.width)
X = x;
This way I can assigned needed coordinates in X range. e.g. 1, 2 ,3 etc But what to do with alphanumeric range. (if for example I want to make it extensible)...

I am working with Flex, and I need to take a relative URL source property and convert it to an absolute URL before loading it.
The specific case I am working with involves tweaking SoundEffect's load method. I need to determine if a file will be loaded from the local file system or over the network from looking at the source property, and the easiest way I've found to do this is to generate the absolute URL.
I'm having trouble generating the absolute URL for sound effect in particular. Here were my initial thoughts, which haven't worked.
Look for the DisplayObject that the Sound Effect targets, and use its loaderInfo property. The target is null when the SoundEffect loads, so this doesn't work.
Look at FlexGlobals.topLevelApplication, at the url or loaderInfo properties. Neither of these are set, however. Look at the FlexGlobals.topLevelApplication.systemManager.loaderInfo. This was also not set.
The SoundEffect.as code basically boils down to
var url:String = "mySound.mp3";
/*>> I'd like to convert the URL to absolute form here and tweak it as necessary <<*/
var req:URLRequest = new URLRequest(url);
var loader:Loader = new Loader();
loader.load(req);
I would also be perfectly satisfied with some way to tell whether the url will be loaded from the local file system or over the network. Looking at an absolute URL it would just be easy to look at the prefix, like file:// or http://.
