Creating PDF thumbnails in Flash cs5.5 AIR

I need a way to create a thumbnail of the first page of a PDF. I am downloading a pdf and saving it locally. I just don't know a way to get the contents of the first page to a bitmap, bitarray or jpg format. I have been using jpgencoder for other image file type thumbnails but don't even know where to go for PDFs.
Anyone have any ideas?

No ~ I do answer questions if I know the answer even on the wrong forum.
And I point to the right forum when I know which it is: this time I know nothing except this is the wrong one!
Good luck

How can I use a file in flash cs6 that I made in flash cs5.5 air for android

I have made an app in in air for android in flash cs5.5 air for android, and I want to edit it in cs6 and play it in cs6.
But if I put Ctrl+Enter I got an error: createWin process failed with error 2: system couldn't find the file. I think the problem is that I'am using air for android 2.6 version in flash cs5.5 and version 3.2 in flash cs6. I have searched the web and found out that you can add older air versions using the sdk manager and I have tried it but first I get the error that the version of the sdk I am trying to install is not valid and after some files that I added to the sdk folder I get this error:Only SDK higher than version 3.4.2540 may be added.
I there a possible way to update the air for android for an fla or apk? Or how can I let my originally file work fine in flash cs6??

system couldn't find the file
If you can´t get a more specific hint why your project can´t compile then I can think of some reasons theis error might occur
1.You had files included besides the swf, like videos, audio files, xml files, that are not present in the place air expects them to be
2.somewhere in your createWin functions there is a class import needed that isn`t present in 3.2 anymore, for example some classes or functions from classes that were valid in 2.6 are not any more in 3.2
3. to achieve better eror logging, allow for debugging in the publishing options and see what specific lines in your code throw the error
4.any air app needs a cert file, this needs to be created once, if you migrated to e new system it might be you never created that file which air expects to even begin the compiling process
once you isolate the problem, report back

[Flash CS5.5 / Air 2.6] Movieclips not showing when .air app is run on Mac

Hello,
I created an application in Flash CS5.5 using Adobe Air 2.6. When I test the app on my computer (where it was written) everything works fine. When I publish the application and run the .AIR on my computer everything works fine as well. The issues comes about when I attempt to install and run my AIR application on a Mac operating system. In this case when the application runs some graphics are visible while some aren't. Some movieclips/buttons are visible while others aren't. One example of this is the buttons. None of the buttons in the entire application are visible. When the user clicks the area where the button should be the button click event is fired and the app acts accordingly (i.e. the main menu button which can't be seen still sends the user to the main menu). What could be the problem?
I had thought of just converting the application to strictly Flash without AIR but I require AIR for the file system api as well as a couple other api components.
Thank you in advance,
Noah

Hi Noah,
I don't think I've run across this before. I'd be willing to give it a try on my system if you'd like (you can email me at [email protected]). Though I suspect this is a project specific issue, it also can't hurt to open this as a new bug over at bugbase.adobe.com.

Creating a component in Flash CS5

Hi,
How can I create a component using Flash CS5? I have tried to follow various documents I have found on google and went about it in the following way:
1. I created an empty FLA.
2. I created a MovieClip containing some graphics, and named the MovieClip "MyTestComponent" in the Library.
3. I selected the MovieClip's properties in the Library and selected "Export for Actionscript", and made the MovieClip inherit from fl.core.UIComponent.
4. I saved the FLA in the directory "C:\Program Files (x86)\Adobe\Adobe Flash CS5\Common\Configuration\Components" and restarted Flash. At this point I would expect that the MyTestComponent component would show up in the Components panel, but it did not.
5. I tried to publish the FLA as an SWC file and place the SWC file in the same file as above. According to my understanding, both this and the step above should have worked, but it did not.
So, what am I missing?
Also, where can I find an up-to-date documentation on how to create components to be used in Flash CS5?

I managed to get it work at the end...
First, the components directory was at this location:
C:\Users\<username>\AppData\Local\Adobe\Flash CS5\en_US\Configuration\Components
Then, to make a component out of a MovieClip, right click on the MovieClip in the library and select "Component Definition" and check the checkbox "Display in Components Panel". What I did then was to right click on the MovieClip and selected export swc file, and saved it in the directory above. This exported only one Component, which was fine for me. Probably it would be possible to do something similar to save a library of components as a .fla or .scw or so, but I don't know the details.

Workflow for creating Flex components in Flash CS5 needs work

Am I missing something? I thought things were supposed to be easier.
I'm creating an AIR application for a client with heavy embedded video.
I have chewed up days on trying to get stuff to work, mostly creating a graphics heavy component that I can use in the AIR (Flex) app.
Just clicking the magic "Convert Symbol to Flex Component" command won't do it if you have created your own .as class for the symbol, because it won't compile unless you extend the UIMovieClip class. Good luck trying to find it in the namespace.
After hours I found where to download the Flex Component Kit that contains the swc that gives you the UIMovieClip class.
http://www.adobe.com/cfusion/exchange/index.cfm?event=extensionDetail&loc=en_us&extid=1273 018#
Notice the title of the page: Flex Component Kit Alpha for Flex 2.0.1
Shouldn't the need for this kit be ancient history? Shouldn't that swc be built in to the new SDK's and/or Flash Builder 4?
Make my living on Adobe products, and love them, but this is sloppy. No documentation. No walk-throughs. Have burned many hours that I can't charge the client for because it make me look incompetent.
Creating a Flex component in Flash with extended functionality SHOULD be a no brainer.

C:\Users\<username>\AppData\Local\Adobe\Flash CS5\en_US\Configuration\Components

Flash CS5.5 Air 3 skd overlay howto?

Didn't manage to properly install Air 3.0 SDK and use it for publishing in Flash cs5.5, getting errors now.
Tried this one,

Any tips/tricks, or perhaps some guide from Adobe lik this one for 2.7: http://kb2.adobe.com/cps/908/cpsid_90810.html
Thanks!

Hopefully this helps somebody.
I followed all the instructions at http://www.yeahbutisitflash.com/?p=2949, but couldn’t get my work-in-progress flash file to use the new AIR 3.1 SDK. The funny thing was, when I created a brand new file, it used the new SDK without a hitch (I was testing with the new JSON class).
As it turns out, I had to go into Actionscript 3 Settings and activate “Warnings Mode” (I usually deactivate this because it makes compiling take forever). When I ran it again, it worked! And after deactivating Warnings Mode is still worked. Not sure why this step was required. Ah, the joys of Flash. ;-P

Font issue occurs when creating pdf file from Illustrator CS5.

I have some design files which are created in Illustrator CS5 and I made them as a pdf file using InDesign CS5 while I open the pdf file in Acrobat Pro 9 I have no issue with the file but my client is using Acrobat Pro 7 while they open the pdf file in Acrobat pro 7 junk characters(rectangular boxes) are appearing in it. Can anyone please look in to this and confirm is this a version bug or something else? It would be much appreciated if some give any idea to get rid of this issue.

Aside from the PDF version, but to follow-up to what David is getting at, you are likelythe fonts are not embedding. Because they reside on your system you see the PDF as it should be. Your client likely does not have the fonts installed.
Make sure your ID export of the document is including the fonts. If that still does not work, check to make certain the fonts you are using allow them to be embedded.
If all else fails, seeing how this PDF is for client review (I assume) have the PDF settings set to convert type to outlines. This gets you past the current dilemma as you figure out the cause.
Take care, Mike

Creating PDF's in PS CS5

I'm using 12.0.1 on a Mac Pro with 10.6.4 and the graphics update. I'm trying to create a PDF using the automate > batch > Save as Photoshop PDF. I have the source as one opened PSD 'Opened Files'. I'm selecting 'Save and Close' as the destination. The file closes and that's it. No PDF.
I'm doing the exact same thing in PS CS4 and I get a 'save as' dialogue box and all the expected options for a PDF file and I get a PDF file. What do I need to do differently here? Thanks!
Also how do I create multipage PS PDF documents with PS CS5? Thanks!

Do you have the enable dialog checked for your action

Creating universal app using flash cs5

Hi,
I'm using Flash CS5 and I wanted to create an universal app (iphone + ipad).
Then I click the "iphone IOS settings" there is no device menu, so I can't choose the desired devices..
I dont know why the device menu has disappeared?
I saw on several video tutorials, that you can simply choose the desired device.
But then I look at my own project and I click the "iphone IOS settings", I cant find any "device" menu by the "general" tab.
Does anybody know how I can resolve that problem?

The iPad support was added later. Get the 11.02 updater here:

Flash CS5.5 & Air 3.1.0.4880 don't include huge amount of external files

My project have included 72 files (36 pngs and 36 swfs) + 2 (main swf and main xml)
Totally 74 files.
Building from Flash CS5.5 return strange error with incorrect text codepage (charset).
When I remove 2 files, so I will have 70 my files and 2 default app file - project builded successful.
From commandline I can build without any errors any file count. But from Flash CS5.5 not more than 74 included files

Sounds like this is a Flash Pro issue, but I'm glad the command line is working for you. Would you mind posting about this on the Flash Pro forums?
Thanks,

Open PDF file in Flash CS5.0

Is there any way to open a PDF file in flash application using Action Script 3.0 ?

By open do you mean import or simply display?
You can use the StageWebView class to display a PDF if the user has a PDF viewer installed. It essentially punts the work off to the system browser to display it. You just tell the StageWebView instance to load the PDF directly. I do that on iPads and iPhones and it works great. Very smooth response and all the PDF controls intact.
Now if the user does not have a PDF viewer installed, that won't work.

How to create a preloader in Flash CS5?

can someone help me with creatinga preloder in CS5?

Here is the code.Create a movie clip and call it logo_mc    Inside that movie clip insert a text field. Make it dynamic. then lable it percent. This will create a nice preloader. Do not put this code in your current project. Create a new file. change "http://www.buttonbeats.com/images/pianonewSounds.swf" to the address of your flash app.
var l:Loader = new Loader();
l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loop);
l.contentLoaderInfo.addEventListener(Event.COMPLETE, done);
l.load(new URLRequest("http://www.buttonbeats.com/images/pianonewSounds.swf"));
function loop(e:ProgressEvent):void
    var perc:Number = e.bytesLoaded / e.bytesTotal;
    logo_mc.percent.text = Math.ceil(perc*100).toString()+"%";
function done(e:Event):void
//    for(var i:uint = 0; i < numChildren;i++){
//        trace("CHILD:"+getChildAt(i).name);
    removeChildAt(0);
    addChild(l);
    var movie:* = l.content;
    movie.play();

Jarsigner finding .p12 certs created by flash cs5 as 'wrong format' ??

I have created an app using flash cs5 and a self signed cert using flash cs5
I now must decompile the app, change the app id and recompile it.
Then sign it using jarsigner.
The problem I have is that when I point jarsigner to the cert I used it says that it is not formatted right.
I know I am missing something, but what?
Using any other cert will result in not being able to update my app. This is bad I know but it is my last resort before unpublishing my paid app and publishing it again.
A lesser option would be for me to reload an old flash extension for air ( probably released early in the air for android pre release ). But I can not find it.
Any help is much needed and thank you in advance.

A .cer file doesn't include the private key, just the certificate that contains the public key.
I suspect the problem is that you need to specify the alias for the private key in the keystore (which can contain more than one). Unfortunately, when AIR creates a cert, it doesn't assign this value, so you have to use the default for whatever tool you are working with. For jarsigner, this seems to be the distinguished name assigned to the cert/key, which is basically the values you used to create the cert, concatenated together.
For example, I was able to sign a jar file with a self-signed cert/key pair generated with ADT using the following command:
jarsigner -keystore file:\\\c:\certs\foo.p12 -storepass passwoord -storetype pkcs12 sudoku.jar "cn=charles ward,ou=learning resources,o=adobe systems\, inc.,c=us"
That last, long bit in ""s is the alias. If I don't use it, then I get the same error you are reporting.
I was also able to import the same keystore into a new Java keystore with the following command:
keytool -importkeystore -srckeystore c:\certs\foo.p12 -srcstoretype pkcs12

Project created in Flash CS3 & Flash CS5 crashes both Safari & Firefox

I have a user with a brand new image including Snow Leopard 10.6.6 and the Adobe CS5. When creating a project in Flash CS5 and then trying to view it in Safari & Firefox the plug-in crashes which then brings down the browser with it. I went and installed Flash CS3 (as this is what he is used to using) and the problem still persists.
Any ideas?
