Help capturing screenshots from script

Hi all,
I'm helping someone with a project, I'm a fairly experienced Unix and Windows developer but don't know much about Macintosh or Applescript so please excuse me if any of these are stupid questions; if you can direct me to the relevant documentation that would be great.
I'm trying to write a script to capture screenshots (actually single window captures of the browser window) and save them to disk every N minutes.. I've seen how to do this with the Grab application, or from the command line using screencapture. I don't see how to automate either of these applications through Applescript though; when I select file-> open dictionary they aren't in the list. Does this mean I can't use applescript to drive them? If so, can anyone suggest an alternative?

You can use AppleScript to execute screencapture:
<pre class="command">do shell script "screencapture -S file"</pre>

Help: Capturing photos from camera while iPod sync

Big problem...
I started my canon sd600 camera to start capturing 90 pictures from my wife's birthay, but I was also sincronizing my ipod and both libraries are in an external LaCie drive.
Immediately after I turned on camera, the iPod Sync failed and also all pictures within iPhoto dissapeared... they were showing an admiration mark... I could only see the pictures just imported from the camera...
The only way I was able to see all pictures was to quit iPhoto and choose again the library. However, when I did this... there were NO pictures just captured!!!!!
Sadly I selected to delete the pictures in my camera after downloading them... Now I lost 90 pictures...
I believe they have to be somewhere since they were effectively captured... just need help to find them!
Can anyone of you friends help me?

Do a search on Macupdate using 'recover photos' and you'll get a lot of suggestions for Software that will recover the photos from your card.

Help with callback from script src= with jsp processing

I am trying to understand several different ways to get dynamic content into a system I am building. These include:
1. <script tags to fetch text from a jsp page
2. <img to fetch images from a jsp page
3. AJAX to fetch text from a jsp page.
(In all cases, the jsp pages will eventually get the data from a MySql database, but right now I am using static code.)
I am having a problem understanding how to use the <script option.
I am starting with an html page with a javascript callback function and a <script with the callback passed as a parameter. The callback function is based on a sample that I found that works, but I don't have the code for the called jsp page.
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>

<title>Test javascript WebServiceCalls...</title>

function ws_results1(obj)
     alert("in ws_results1");
       var myobj = obj.ResultSet.totalResultsAvailable;
       alert("The result is "+myobj);
     this.document.getElementById("showTest1").innerHTML = "The result is "+myobj;
</script>
</head>
<body >
<h2 > #1 <SCRIPT tag with immediate loading..... </h2>

NOTE: <br>
1. Page will delay loading until response is received. <br>
2. Target for callback function must preceed the %lt;script tag as it must be loaded first or it will not yet exist when the callback function executes.<br>

   response.setHeader("Cache-Control", "no-cache");
   response.setDateHeader("Expires", 1);
   response.setDateHeader("max-age", 0);
   OutputStream os = response.getOutputStream();
   baos.writeTo(os);
   os.close();
   System.out.println("TestWS1.jsp: done");
%>When I run TestWS1.jsp, I get the expected entries in the system log and the expected output:
"TestWS1: This is the returned string as HTML <br> This can be any HTML code.<br>"However, when I run the TestWS1Call.html, I get the entries in the system log but nothing fires the javascript function.
What am I missing?
Thank you

I found a solution to loading dynamic content using the <script src= tag.
This approach seems to be useful (a) for situations in the jsp content is dependent on client-side characteristics
(such as window size) and (b) because it seems to work on any browser with javascript and does not require an
ActiveX for older versions of IE.
I wrapped the output of the jsp page inside a javascript call to the callback function
   ps.println(callback+"(\"TestWS1: This is the returned string as HTML <br> This can be any HTML code.<br>\")");I also changed the content type to javascript.
   response.setContentType("text/javascript");Now, when the script tag is found, the jsp page returns a javascript function call to the callback function and passes
the desired content as a single parameter. The callback function then places the content in the appropriate
location on the page.

Capture screenshots automatically

is there a plugin that captures screenshots from my movies automatically (like every 20secons ...)?
thanks

iMovie 6 has that (new) feature. It lets you import video from the camera with a time-lapse effect. If you're thinking of upgrading, that is a solution.
This is from iMovie Help:
To create a time-lapse effect:
Turn on your camera, and connect it to your computer. If you need help with this, see Related Topics below.
In iMovie HD, press the camera icon (shown above), and choose Time Lapse from the pop-up menu.
Select the Capture Frame checkbox and specify the number of frames from which you want iMovie to capture one frame of video.
Click OK.
Import your video into iMovie as you normally do, using the iMovie capture controls. If you need help with this, see Related Topics below.

Word 2010: Insert Screenshot from IE shows black thumbnail

My environment is a QA software testing environment where we have to capture screenshots from our company software that runs in Internet Explorer 8 and 9. Once we upgraded from Word 2007 to 2010, we started using the "Insert - Screenshot"
feature to capture our verifications. Any employees using remote desktop to connect to their work stations from home frequently (but not always) see a black thumbnail for IE rather than the IE screen itself. All other screens within the screenshot
window show properly. Just the IE ones are sometimes black.
And now one analyst is having the same problem logged in here at the office (not remote desktop).
I saw one solution for disabling the "Send to Bluetooth" add-in, but we don't have that one. Another solution recommends adding a registry entry for AllowImageProxyAuth, but no one has reported trying it and whether it worked. I did
not want my work PC to be the guinea pig for this. Any recommendations?
From other solution:
Go to "Start" button > in the search field, type: regedit > HKEY_CURRENT_USER >Software > Microsoft > Office > 14.0 > Common "single-click" > from menu: Edit > New > DWORD (32-bit) Value > type: AllowImageProxyAuth
> right-click this file and choose: modify > in the value data type: 1

Hi,
I can reproduce this error in Windows7 Office 2010(32-bit/64-bit) IE9, this issue only appear using Remote desktop to connect remote workstation. The problem cause by Remote Desktop session, it will lock out remote workstation Windows, Windows client
service(termsrv.dll) did not support multiple user logon like Terminal Server. AFAIK, this is a known issue, Microsoft maybe fix it new update release.
And the registry key "AllowImageProxyAuth", it's only apply to Outlook 2010 if the image is not displayed.
http://support.microsoft.com/kb/2457649
You can use PrintScreen as a workaround:
Start IE > Press "PrtScn" or "Alt+PrtScn" on Keyboard > Start Word, Press "Ctrl + V" to insert screenshot.

How can I capture a snapshot/screenshot from my game made with edge animate

I am wondering if its possible to put a symbol button inside edge animate once the user clicks on it it downloads a screenshot from the current screen the user is on because it's a required inside the project I have made and the client is really asking for this advantage and I made the whole game with edge animate so please if anyone has any solutions to tell me about them..Thanks

Hey, HeavenChains-
We don't use canvas natively, so the html5 canvas screenshot may not work for you. I did a quick websearch and there are libraries out there that may take a screenshot for you, but you may want to be wary due to privacy concerns with using third party software.
Here's one of the ones I found (please don't take this as a recommendation, as I haven't tried it myself):

Help me capture stills from mov files of kodak camera created in pal format

I did not know the difference and saved movie files on my kodak digital camera as pal format - it was top of list - i need to capture some stills as single photos from those files. I have switched to NTSC format for future and will want to capture stills from movies in that format also
does anyone know if quicktime pro 7 will di what i want or what i need to reach my goal?

Even the free version of QT Player allows you to "copy" frames. These could be "pasted" into a new blank using any image editing software.
What ever frame is showing when you stop playback will be the one copied. More control by using the right left arrow keys.
The Pro upgrade can export a frame to many image formats. It doesn't matter that the format is PAL. NTSC and PAL are TV playback settings. Your computer doesn't care.

Make a screenshot from a panel?

Hi,
is it possible to make a screenshot from a panel? And save it
in some object?

yevgen_78,
Flex 3 has an ImageSnapshot class which may do what you need.
For more information, see
http://livedocs.adobe.com/labs/flex3/langref/mx/graphics/ImageSnapshot.html
Also, there are a few random examples at
http://blog.flexexamples.com/category/imagesnapshot/
which may give you some ideas.
As for saving the pixels, you would probably need to send the
raw image data to a server side script (ColdFusion, PHP, ASP, etc)
to save it to a file.
Hope that helps,
Peter

PrintWindow api with possible solution for capture screenshot Google Chrome window

Hi,
as all you know, PrintWindow api give us a black image when us want a capture screenshot of Google Chrome window. So, a friend said me that a possible solution for this problem is:
Reduce Google Chrome window for -1px in both sides and after this, reset to original size. And so, will repaint again.

Capture image from isight

What is the best way to capture images from iSight using Applescript ?

erritikamathur wrote:
What is the best way to capture images from iSight using Applescript
(1) Depending on what you want to do, you may be able to use your "Automator" application to make your scripts instead (Automator calls them "workflows".)
When you launch Automator, you can immediately select the "Photos & Images" as a starting point to see if it will meet your needs by selecting "my Computer's Camera" in the "Get content from:" choices bar there.
For more info on Automator, start with Mac 101: Automator and then launch Automator on your Mac and use its Automator > Help as needed.
(2) If you really need to use AppleScript, you need to understand that you script applications (such as iChat), not devices (like iSight.) Therefore, first decide what you want to do with your iSight. Click -> here to see a list of some applications that can operate your iSight.
Once you have decided what you want to do, launch your Mac's AppleScript Script Editor.
Next, open Script Editor's Library window to see a list of Apple apps that are scriptable. Those that can control iSight include iChat, iMovie, and iPhoto. Double-click on one of the apps of interest to see the dictionary of functions that can be scripted in that application. Reviewing the library for any app will help you determine whether the functions you want to control can be scripted in that app. If not, you need to find another app that can control that function, develop an alternate process flow that can be scripted, or look for a way to accomplish your task other than with AppleScript.
Some third party apps may also be scriptable. See the documentation or support info for particulars directly from the developers of those apps.
More help is available from a variety of sources. For instance, you can check your Mac's Help on specific applications to see if they contain info on automating them. One specific example is iChat > Help, which gives a good start on your iChat study.
Unless you already know how to use AppleScript, you may also need to do some more general study or perhaps take advantage of the Apple training series book available from the Apple Store.

Adding a screenshot via script

I often have to put a screenshot in photos of computers and tvs and I want to be able to script this somehow. If I set a path, or shape, or points, is there a way to take another image and place it to fit inside those point (so all corners would meet?) Right now I just place the screenshot image on a separate layer and use Distort transform to match the corners of the screen and screenshot.
Any thoughts?

Some time ago I stumbled onto something that I’m afraid I don’t quite comprehend in »Geometry.jsx«, but might help you.
This Script should transform the activeLayer according to a path named »screen« if it has four points – the Script might need some more work …

Scripting - Passing and Enterprise variable from script to script

Hello all,
We are using UCCX 7.0_SR5
I am looking to be able to pass a captured variable from one script to another.
We use a message in queue where a caller waiting in queue can choose to leave a message and then that message is queued back into the sytem for the next available agent. When that agent recieves the message in queue they basically call back out to the customer leaving the message.
We capture a variable in the first script when they decide to leave a message. The variable holds the call back number that they enter into the system. There is a second script that presents these message in queue calls to the agents. We would like to pass that variable that holds the number enterend by the customer to the second script so that that number appears on CAD in the enterprise data fields. The reason behind this is so the agent has a number to call back in the event they don't reach anyone when the system calls back out and the message left by the customer does not contain a call back number.
How can I pass that variable from one script to another so it can be presented in CAD for the agents?
Thanks for any help and let me know if you need any further information.

You would use a "Get Call Contact Info" step to set your callerID variable, where the "Calling Number" attribute is set to your callerID variable.

Unable to capture video from VHS through DAC-200

(Running Final Cut Pro 5.1.4)
I have a DAC-200 to hook up my VCR to my G5 in order to capture video from VHS tapes into Final Cut. I had this set-up working a few months ago, but it was disconnected to rearrange equipment and now I can't get it working again. I have followed the advice from the DAC-200 installation instructions and advice from other forum topics but can't seem to get it to work. I finally was able to get something in the log and capture window besides "preview disabled" and "cannot capture because there is no video." I now can get Final Cut to capture video, however it only captures a blank black screen (and this is all I can see in the preview window).
I've triple-checked every cable hook-up, the G5 recognizes the converter box, the video tape plays fine to a tv. I've even had our IT-guy here at work come check out my set-up for help and he can't figure out what is wrong either. (He did get my log&capture window to get white fuzz in the black screen at one point though. Does that mean anything?)
Any help is greatly appreciated! (I'm happy to answer any other questions too.) Thanks!

I had difficullty with the X.4.10 plus QT7.2 and put my info on the Forum as well as sending feedback to Apple. Shortly afterwards, Apple brought out a short security update which I downloaded and, hey presto, I was then able to use QT7.2 with OSX.4.10. It may be that you missed out on the later small update to QT7.2..... ? Another factor I found was that some little while later I again had a problem so I again installed QT7.2 and over-installed FCP5.1.4 which has resolved my problems for the time being. Worth a try if you still can't get through on the DAC.
