Compositing interior and exterior

Using RAW images, where can tutorials be found for compositing interior shots with a view out a window?
TIA

Whether you can do it in real time depends on things like the processor speed, video frame size/rate, and complexity of the compositied graphics. To use JMF, you will have to write a codec to modify the video stream as it's being displayed (you can base it on Sun's FrameAccessCodec example). The codec would receive each frame as a JMF Buffer, convert it to a BufferedImage which you can use Java2D to draw on, convert it back to a Buffer, and pass it on for display.
Other approaches, such as drawing the graphics on a panel over the movie may not work reliably due to heavy/lightweight component conflicts.

RGB, Composite, Firewire and S-video capture device for FCP

Hi,
I was just wondering if anyone could suggest some of the better capture cards that support RGB composite, firewire and s-video inputs that will work with FCP.
The set up is on Mac Pro and the device needs to be as reliable and noise free as possible as it will be used for the capturing of video for evidence in court cases.
Any help is this area would be very grateful,
Regards,
Martin.

Hello,
I have no experience with the AJA product line but I know that many of the folks here have used them. They make a good line of cards that will do what you are asking for. They don't have firewire on the cards, but the computer you are using should have one I would assume.
Since you said 'S-Video' my thoughts are that you are only using SD? If that is going to be the case for a long time then look at this card:
http://www.aja.com/products/kona/kona-lse-ls.php
It has composite and S-Video inputs. IF there is the chance that you are going to be doing HD and IF it is still tape based, then look at one of the higher models. But again, that is if you are going to be upgrading to HD sometime soon.
Hope this helps.

Question about composite index and index skip scan

Hi,
I have a confusion.
I have read Burleson's post on composite index column ordering (http://www.dba-oracle.com/t_composite_index_multi_column_ordering.htm) where he writes that
"......for composite indexes the most restrictive column value(the column with the highest unique values) should be put first to trim down the result set..."
But 10g performance tuning book tells this about INDEX SKIP SCAN ::
"... Index Skip scanning lets a composite index be split logically into smaller subindexes. In skip
scanning, the initial column of the composite index is not specified in the query. In other words, it is skipped.
The number of logical subindexes is determined by the number of distinct values in the initial column.
Skip scanning is advantageous if there are few distinct values in the leading column of the composite index and many distinct values in the non-leading key of the index......."
So if we design Composite indexes acc. to what Burleson said then how can we take advantage of index skip scanning. These two staements oppose each other,don't they ?
Can anybody explain this ?

Dear,
For the moment forget the distinct values and the compressibility. I've tried to reproduce your case here below (using jonathan lewis table script)

    mod(rownum,5000)    c3,
    mod(rownum,10000)   c4,
    lpad(rownum,10,'0') c5,
    rpad('x',5)         c6
from
    generator    v1,
    generator    v2
where
    rownum <= 1000
alter table t1 add constraint t1_pk primary key (c3,c4,c5,C6);
create index idx_1 on t1 (c1,c2);

Why is my Hardware Accelerate Composition, Layer, and Footage Panels check box disabled

Hello anyone!
I have all the requirements to meet Adobe's standards for GPU requirements, but this check box (Hardware Accelerate Composition, Layer, and Footage Panels)[Edit>Preferences>Display] is disabled for me, why? Do I need to worry about this setting? Does it really matter? Any information on this topic would be helpful. Thanks in adavance for your feedback.

Feature support levels
There are three tiers or levels, from lowest to highest requirements, of support:
Level 1: For OpenGL SwapBuffer:
This level simply requires a GPU that can do OpenGL 1.5, or greater, with Shader Model 3.0, or greater. Most ATI and NVIDIA cards, and the Intel HD Graphics 3000 chipset (available in the MacBook Air, Mac Mini, various Windows machines, etc.) and 4000 (Windows only at this time) are supported. If your GPU does not support these requirements, software OS blitting like CS5.5 occurs, and there are improvements for software blitting in After Effects CS6, as well.
Level 2: For Fast Draft previews, Hardware BlitPipe, and Cartoon GPU acceleration:
Includes Level 1 features. This level requires OpenGL 2.0, or greater (with Shader Model 4.0, or greater, on Windows), and 256 MB, or greater, of texture memory. Most ATI and NVIDIA cards released in the past five years, plus the Intel HD Graphics 3000/4000, support this level.
If your GPU does not support these requirements, these features will be disabled:
Fast Draft mode
The "Hardware Accelerate Composition, Layer, and Footage Panels" preference.
The Cartoon effect's "Use OpenGL When Available" option (the Cartoon effect then runs on the CPU).
Level 3: For Ray-traced 3D rendering on the GPU:
Includes Level 1 & 2 features (for machines with attached monitors). This level requires a supported NVIDIA GPU and 512 MB, or greater, of texture memory. For a current list of supported GPUs, see the Adobe website.

Well, you should be concerned that it isn't available - there is still some configuration issue with your graphics card - but you can live without it most of the time.

JSF 2.0: Composite Components and their ID

I'm using Composite Components with JSF 2.0.
Template:
<composite:interface />
<composite:implementation>
    <h:inputText id="text" />
</composite:implementation>Template Client:
<h:form id="form">
    <components:myComponent />
</h:form>In the rendered result, the h:inputText's id will be "form:j_id1060595728_4b62ee3:text".
How can I override that default ID?
I tried to set an id attribute on composite:interface and composite:implementation, however, that doesn't have any effect.
Using ui:debug, I found that the component with ID "j_id1060595728_4b62ee3" is a UINamingContainer.
When using my own UINamingContainer implementation, i.e., ...
<composite:interface componentType="util.jsf.UINamingContainerWithID" />
@FacesComponent("util.jsf.UINamingContainerWithID")
public class UINamingContainerWithID extends UINamingContainer {
     private String id = "foo";
     @Override
     public String getId() {
          return id;
     @Override
     public void setId(String id) {
          // this.id = id;
     public void setFooID(String id) {
          this.id = id;
}... I can prevent the id from being set in setId(String), and h:inputText's id will be "form:foo:text".
(I have tried to debug but the source code is slightly out of sync.)
I also tried to add an attribute fooID to composite:interface and composite:implementation, with no effect.
How do you work with Composite Components and their IDs?
Thanks

All composite components are NamingContainers. This is necessary to prevent ID collisions.
In order to avoid a generated ID on a particulare composite component, specify an ID in the component
within the using page:
<h:form id="form">
    <components:myComponent id="c" />
</h:form>So the client ID of the text component would be: form:c:text.

Composite photo and background layer question

I would appreciate some help with a workflow problem when dealing with a composite, selection and background layer. My normal workflow is to start of in LR4, and if need be do an "edit in, CS6". I am relatively new to CS6, so bear with me.
I have some portraits I want to put different backgrounds on. I am using Matt Kloskowski's Layers book and Composites books written for CS5. I also have Martin Evening's book on CS6 and the workflow for doing a composite is pretty much the same. The catch is that none of them start off in LR with the original photo. They all describe the following basic workflow pattern:
1. Bring up the main photo in CS using "edit in CS6"
2. Change the photo from a background layer to a regular layer
3. Make a selection.
4. Make a layer mask
5. Refine the edge
6. open the background photo you want to place the selection in (steps 4 and 5 are sometimes reversed so you are refining the edge on the new background)
7. copy and paste the original photo onto the new background
8. Refine the edge if not already done
9. Save and exit back to LR with the composite
If I follow this procedure I run into a couple of problems:
1. My backgrounds are in a separate folder on my computer and not cataloged in LR. So, if I open them in photoshop and paste the original photo onto that image, LR will not know that I want to take the new composite back to the original folder along with the protrait. If I go to save the image, CS want to take the composite back to the folder on my computer where I got the background from. I tried playing around and tried renaming the composite similar to the naming convention I use for my photos in LR and then importing it into that folder after I have saved it in the background folder. This had some unintended consequences. First, I had trouble renaming the composite photo. For some reason Windows kept plugging in an old photo file name from one of my photos taken two years ago. After I discovered that I could work around it. But after the first composite finally got into LR, when I tried to do it again, the import button on the left side of my LR went dark and I couldn't import the second composite photo I was working on. This could have been a coincident and unconnected LR glitch, but I have never had that problem before.
So...I was thinking of modifying the workflow to the following:
1. Bring up the main photo in CS using "edit in CS6"
2. Change the photo from a background layer to a regular layer
3. Make a selection.
4. Make a layer mask
5. Refine the edge
6. open the background photo you want to place the selection in
7. copy and paste the new BACKGROUND onto the original photo
8. Move or make the new background layer THE "Background" layer
10. Refine the edge
11. Save and exit back to LR with the composite
I am envisioning this will ensure that my composite will wind up back in LR because it is still keeping track of the original photo which now has gotten the new background, regardless of what the file name of the new background was.
Does any of this make sense? Does any one know a better way of handling this?
Thanks for any help,
Jim

Yes, it makes sense and I think you should go ahead and try it.

Hardware Accelerate Composition, Layer, and Footage Panels - optimize

Hello.
The AE preference for "Hardware Accelerate Composition, Layer, and Footage Panels" makes my deep compositions workable - for a limited time, and then simple selection tasks slow down substantially, as if I had turned this checkbox off. What can I upgrade to have more "fast time" with After Effects? Thanks for any insight into how to make my system work. Also, this may be my last Mac.... Is anyone out there able to run hundreds or thousands of layers in After Effects on a PC without having simple select tasks slow down?
• simple selection task = "select all" in a single open composition with 10 layers or with 400 layers, although only in a project which contains deep compositions.
• This slowdown exhibits with or without caps lock enabled
• This slowdown exhibits before and after purge all

You are using to graphics cards of different model? That's probably why. I've really tried to see a difference with that switch and it's not measurable, so don't worry about it!

USB interface to composite video and audio

I've been searching a long time for a compatible, low cost and convenient capture device for composite video and audio. The EasyCap devices are super cheap, but their audio section is just horrid. Others won't provide audio usable by Adobe Connect. The EZCap 116 seems to work very well with Adobe Connect, providing a single USB cable connection that carries both audio and video. To get it to work with Skype you need to use Splitcam. the only reminaing annoyance is that you have to use the bundled software each time you want to get the device to use composite or S-video inputs. Sure wish the Flash module would let you configure webcam settings directly.
My main application for the gadget is to interface our institutional VC codecs (which have VCR outputs) to Adobe Connect users.

Studio X: Doh!, you beat me, with your maximally cryptic reply!

Composition Environment and CAF

Can someone please let me know, in simple terms what is Composition Environment and when is it needed (in business sense). i.e. What functionality it provides that is not available with normal NW based systems.
Secondly, what is composite applications in reference to EP system.

Hi,
1.The main idea of CE 7.1 was to build Composite applications. It is not a complete portal. EP 7 is a complete portal platform with KM.TREX and Collaboration. CE 7.1 doesnu2019t have all these components and it cannot be used as a complete portal platform. You can integrate CE 7.1 with EP 7 using Federated portal

Representing SOA/Composite service and operations

Which diagram/diagrams do you recommend for depicting a SOA/Composite Service and their operations?
Example:
We have a process function "Mutual Acceptance" that requires customer data,
which is in another software module for handling customer master data.
The service is called "Manage Customer" and the operation "Query Customer".
I am thankful for any input, best regards Fredrik.

Hi Fredrik,
Just some quick notes regarding this complex theme.
To describe the relationships of a business service to other architecture elements create a Business Service Allocation model for each Business Service. Therefore use the diagram type IS Context Model to depict:
* software services implementing the business service
* business data owned by the service
* capabilities
* organizational units
Furthermore Access diagrams can be used to depict a software service with its operations, data input and output, capabilities and roles (as far as notifications or workflows included). An Access diagram gets autoomatically generated while the import of a WSDL. Enrich the diagramm type according to your requirements (for operations you can use the symbol IT Procedure). At the end of the day the model shall serve a descrption for the implementation. Hope this is what you were looking for.
Best regards,
Danilo

Discovery V3 with Composite Environment and ESR

Dear experts,
is it possible to upgrade the SAP discovery system V3 to an v3 enhanced?
Concret: Unfortunatelly in the v3 system the composite environment and the ESR is missing. Is it possible to integrate these two elements in the v3 system?
Thanks a lot.
Gordon Borst

Hello Gordon,
I also have DS v3. But to have CE on top of it i have downloaded the trail version of CE 7.2 from sdn and installed on DS v3. Now i have already prototyped many scenarios using both the platforms. And i can see they both fit together very well.
So i am sure you can also do the same. And its quite a task.
Good luck.

Odd behavior when using custom Composite/CompositeContext and antialiasing

Hi,
I created a custom Composite/CompositeContext class and when I use it with antialiasing it causes a black bar to appear. I seems it has nothing to do with the compose() code but just that fact that I set my own Composite object. The submitted code will show you what I mean. There are 3 check boxes 1) allows to use the custom Composite object, 2) allows to ignore the compose() code in the CompositeContext and 3) toggles the antialiasing flag in the rendering hints. When the antialiasing flag is set and the Composite object is used the bar appears regardless of if the compose() method is executed or not. If the Composite object is not used the bar goes away.
The Composite/CompositeContext class performs clipping and gradient paint using a Ellipse2D.Float instance.
a) When the Composite is not used the code does a rectangular fill.
b) When the Composite is used it should clip the rectangular fill to only the inside of a circle and do a gradient merge of background color and current color.
c) If the compose() method is ignored then only the background is painted.
d) When antialiasing is turned on the black bar appears, i) if you ignore the compose() method it remains, ii) if you do not use the Composite object the bar disappears (???)
NOTE: the compose method's code is only for illustration purposes, I know that AlphaComposite, clipping and/or Gradient paint can be used to do what the example does. What I am trying to find out is why the fact of simply using my Composite object with antialiasing will cause the odd behavior. Been trying to figure it out but haven't, any help is appreciated.
Thx.

I got a better version to work as expected. Though there will probably be issues with the transformation to display coordinates as mentioned before. At least figured out some of the kinks of using a custom Composite/CompositeContext object.

Composite windows and Fle dialogs

Hi everyone,
I am working on a GUI object of type Composite which has a text field and a (Browse) button. It has been programmed so that when the user presses the Browse button, a file dialog opens up. Now the problem that i am having is that after the file dialog opens up i am still able to bring the Composite window, sitting in the background, up front by clicking on it which i don't want. I have tried using the setEnabled() method on the Composite but it just disables the browse button and the text field, but does not completely block the user from the composite window since one can still bring it up front. Is there any way to achieve the following functionality?
The user clicks browse the file dialog opens and as long as the user selects the file the file dialog is active and the composite window in the background remains inactive, once the user has selected the file the composite becomes active again.
This is just like if, in your Internet browser, you click file->open and out pops the web address input window where you type in the web address of the web page you want to visit. During this time you can't click on anything in the background unless and until you close the web address input window. Any help is appreciated. Thanks!

As suggested above if you are using JFileChooser then
is is automatically displayed as a modal dialog.
If you are creating your own FileDialog, then you
need to make the dialog modal and specify the JFrame
as the parent when you create the dialog.Thanks for support.

URGENT: How to selectively migrate composite instances and task data from one env to another

Gurus,
We've come across a situation whereby we need to migrate instance data (including Human Task related) of some specific composites from one environment to another.
(Environment is equivalent here to a different domain installation on different physical server.)
Is this possible in some standard way like using Oracle import-export utility or script?
If not, how can this be achieved?
Thanks in advance for any help you can provide on this.
With regards-
Ashish

Hi,
If your SharePoint environment supports InfoPath Forms, then you can customize the form and add rules to make the list items as read only when user A submits the form.
you can then write a form load event to check the logged in user using username() function. This logic can be implemented in variety of ways, like setting a flag when User A submits the form, or storing user A username in a form variable etc., else comparing
User A and User B values within form Load event.
Another way of doing this is using Views or grouping all of the User A fields within a section etc.,
The above would take care of Form logic, and for the workflow, you can use SharePoint designer to create a custom workflow, where it will run on onItemCreate and onItemChange events.
The logic for workflow would be if the form Submitted for the first time, the workflow will start and send an email to User B, and when User B submits the Data then onItemChange change event will start the workflow to send an email to approver to approve
the data.
