JtextArea Key Filter

I want to filter the keystrokes on a JTextArea so that certain characters won't be displayed.
I tried to dispatch a backspace after the filtered characters using:
console.dispatchEvent(new KeyEvent( sp, KeyEvent.KEY_PRESSED , System.currentTimeMillis(), 0, KeyEvent.VK_BACK_SPACE, (char) 8));But I couldn't get it to work.
How can I achieve this??
Thanks,

so that certain characters won't be displayed.If the character is stored in the Document, then it will be displayed unless you write a custom view.
If you want to prevent the character from being added to the Document then you should use a [url http://java.sun.com/docs/books/tutorial/uiswing/components/generaltext.html#filter]DocumentFilter.

Sharepoint 2013 Document Library MetaData Key Filter

Hello,
I created a document library with some fields like Client Name(text), Client Type(choice), Document Type(choice). After that I would like to use that metadata to help me to search documents. I realized that only choice fields are included in the
key filetr(Client type and Document Type). Is there any way to add the client Name in the Key Filter section, so I can search documents by client name also.
I am not sure if this problem can be fixed using metadata key filter or I should create a folder structure in the document library to do what I need.
If you have any advise about the best way to impolement this problem will be appreciate.
Thank in advance.

Yes you can do that.
You need to add custom column to get indexed and the use it on search results page. Try below:

Very bad interlaced effect on Chroma Key filter

Hallo everyone,
Does anybody know why when I try to apply a croma key filter on Motion the image I get is like this ?

DV has a basic problem when trying to do a chroma key - that is it achieves its compression in the color channel - its color information is 1/4th that of its luminance resolution.
This is a quickie - using Conduit to key in Motion:
You can find out about Conduit here:
http://www.dvgarage.com/prod/prod.php?prod=conduit15&sub=samples
Check out the movie on keying DV for some insight into the limitations of keying DV. dvGarage also sells dvMatteBlast that handles all of this - a very nice product and they have a test version you can try...

Problem when add Chroma Key filter to DVCPRO HD

I ingested some DVCPRO HD 720Pn footage into FCP. The footage was shot against a green screen. I started by creating a 4-point garbage matte around the person and then I added Color Smoothing and when I add the Chroma Key filter, the green screen comes back and a large grey area appears on screen. What is going on?

Ok, I just tried it again by creating the 4-pt matte and as soon as I drag the Chroma Key Filter to the clip, the points disappear, and the entire green screen comes back. Is this the way it is supposed to behave? Is there some type of apply button that I need to select after adjusting the last point of the garbage matte before doing anything else?
Thanks!

Motion 5 freezes after applying the keying filter

Why does my screen freeze (four or five yellow/green bands, curser turns to rotating ball of death) when i try to apply the keying filter in Motion 5?

What's your hardware configuration, mainly what GPU do you have?

How do i use my own image with keying (or green screen)

how do i use my own image witrh keying (or green screen)

Put your sky clip on a layer below the clip you want to key. One or the other will be a connected clip. Apply the Keying filter to foreground clip (the one with the green screen). The green will be seen as transparent and the sky will show through as the BG. Adjust as necessary in the Inspector.
Good luck.

In a document library : group by view and manage metadata filter & Navigation problem

Hi all, I encounter a problem when configuring a document library using a group by view and in combination with the Managed Metadata filtering and
navigation :
- all the documents appear under my group by, even the ones that does not correspond
- In the other hand, the number in brackets shows the correct number of documents that should be shown
See screenshot below.
Did you already encounter that issue ? Is there a workaround ?

Hi,
According to your post, my understanding is that you wanted to use a group by view and combine with the Managed Metadata filtering and navigation in a document library
to show the corresponding documents with the correct numbers in SharePoint 2013.
In my SharePoint 2013, I created a view which was group by two columns and combine with the Metadata Navigation Hierarchies and Key Filters some fields in a document
library. As a result, it showed only items matching the filter values.
So, I recommend that you can follow the steps to implement it in your environment.
Step1: Enable Metadata Navigation and Filtering:
Metadata Navigation and Filtering is a Site Feature that has to be activated for this to work.
And, the Metadata Navigation and Filtering feature is enabled by default on most sites.
If it is not enabled for your site, you can enable it on the Site Features pages for your site.
You must be a Site Owner or a Site Collection Administrator to enable Metadata Navigation and Filtering.
1. Go to “Site Settings” and click “Manage site features” under Site Actions.
2. Find “Metadata Navigation and Filtering” in the Features list and click “Activate”.
Step2:
Configure Metadata Navigation:
You must have a least the Manage Lists permission level to configure metadata navigation for a list or library.
1. Open the document library for which you want to configure metadata navigation.
2. Go to “Library Settings” of the document library and click “Metadata navigation settings” under “General Settings”.
3. In the Configure Navigation Hierarchies section, select the field or fields you want to display in the navigation hierarchy and then click “Add”.
4. By default, Folders are automatically displayed in the navigation hierarchy. If you do not want folders to display, select Folders, and then click Remove.
5. In the Configure Key Filters section, select the fields you want to add as Key Filters, and then click “Add”.
6. In the Configure automatic column indexing for this list, specify whether you want to automatically create indices on this list to increase the performance of the
queries that users will perform when they use the Navigation Hierarchy and Key Filter columns you've specified. It is recommended that you select the option “Automatically manage column indices on this list”.
7. Click “OK”.
Step3: Set a group by two columns by modifying view in the document library:
1. Go to the “LIBRARY” ribbon of the document library and click the “Modify view”.
2. Click the “Group By” and select up to two columns to determine what type of group and subgroup the items in the view will be displayed in.
3. Click “OK”.
Step4:
Go back to the document library, apply Navigation Hierarchies and Key Filters to do a test in your environment.
The result will like as below:
There is an article about how to apply Metadata Navigation Filtering in SharePoint 2013 for your reference.

Background disappears after adding a cross dissolve to a keyed clip.

I have a clip that has a Keying filter (as well as being cropped and scaled down) on it over a white background. After adding a Cross Dissolve to the keyed clip, the white background disappears for the duration of the Cross Dissolve, leaving a black background behind the keyed clip. This black background is present both in preview and after rendering.
Any advice?

not positive this will help, but try this:
remove the transition
right-click and sselect "make compound clip" (or Option G)
within the compound clip, drop a white solid under the keyed clip; do not place any transitions at either end of the compound clip.
return to your storyline / sequence
place your transition again and see if it's fixed
if you still do not have a clean dissolve, remove the transition and then click once on the compound clip and go to around 8 or 12 frames before the end and in the inspector, go to the opacity and add a keyframe and then arrow right to the frame before the last frame and add another keyframe and drag the opacity value to zero.

Keying out backgrounds

Hello. Would someone know how to key out an undesired
video background (grey sky) and replace it with another background (blue sky)? What would the process be?
Thanks,
Jordan

It's all going to depend on the complexity of the situation. ie, is that the only sample of that particular color in the entire frame, how consistent is the color of the key'd portion, etc.
I'm guessing that ae is the only concieveable route. Although, especially if it is a still frame, you could get fairly good results with the color key filter or the limit effect in 3-way color corrector.
Post more in-depth info, and perhaps someone else can help you more than me.

FCP Chroma Key requires re-render after any changes

FCP: version 602A89
In an HD 1080i60 sequence - there is a clip - the Chroma Key video filter has been applied to a pretty-well-lit 'stinger-green' backdrop. By making adjustments anywhere in the Chroma Key filter visual dialog, the entire green-field returns and cannot be eliminated except by re-rendering the clip.
See EXAMPLE IMAGES at http://www.glorioski.com/fcp/chromakey.html
I guess this could be submitted as a bug - but I am thinking there MUST be something I am not doing or have inadvertently set (or unset).
Any ideas?
Thanks! Lance Drake

Hi Jerry,
Hey thanks for your response to this question - but, I do not believe that this has always been the behavior with regards what has been presented in the canvas - at least for the current frame.
It's quite reasonable that re-rendering will be needed to apply the changes to the entire clip. However, my point is that, as adjustments in the Chroma Key filter are made - the results of the previous setting of the filter are completely abandoned and the single frame displayed in the canvas reverts to the case as if the filter had never been applied.
The BIG drawback to this behavior is that you cannot see how slight changes in filter settings affect what will be the result were you to go to the trouble of re-rendering the entire clip. Having to re-render with every adjustment sticks you in a huge time-hole.
I wish I had a system with FCP 5 on it - it would be interesting to see how FCP used to behave. Am I nutzo? Somehow I don't think so. It's my recollection that it was possible to make changes to the ChromaKey filter - see the effect of those changes rendered into the single frame of the canvas - and then it was up to you to cause the rest of the clip to be re-rendered.
Unless somebody kicks in with specifics regarding the error of my ways, I am thinking this should be submitted to bugreporter.

Chroma key problem

can I completely customise a colour selection? I have a shot with a lot of blue in it, deliberately, and a small area of green, basically a mini-green screen, that I want to key out. whenever I add the chroma key filter to it it seems to automatically remove the blue. I've tried using refine key>sample colour to choose the green, which works, but only adds the green to the blue. using the colour selection produces the same effect, I can't move the blue line beyond the blue section.
what I'm assuming is happening is that FCPX is automatically detecting the blus in the shot and "deciding" for me that this is the colour to remove, which it isn't. I can't find a way to use chroma keyer without this incredibly annoying automatic feature turned on. I've tried to 'reset parameters' in the chroma key inspector which just removes any adjustments I've made.
I'm new to FCPX having had to move from FCP7 because all our college computers got upgraded. I'm used to being able to use the old key effects where you could select very specific colours and have complete control over range, spill, etc. so this new lack of control is incredibly frustrating.
thanks

I've tried reseting every one of the seperate selections and nothing happened. playing around with it more I've found that dropping the strength to 0%, effectively removing the key and then using the refine key to select the green works, which seems weird to me. I can't adjust the strength beyond 0% though as that still effects the blue in the shot.
it's the automatic nature of the keyer that is bothering me, it seems to select the colour from the shot before I've done anything. in a previous green screen shot, where it was a more standard setup it automatically selected all the green in the scene. the control with the sliders, refine key, etc. are great, I just wish there was a way to turn off this initial auto-select.

How to protect an area in a chroma key?

Hi Folks,
I'm having a bit of a problem performing a key on a section of footage. There's an article in the foreground that unfortunately is the color of the greenscreen (bluescreen actually). Is there any way to 'protect' that area so that the chroma key filter doesn't affect it? The closest solution I've come up with is to duplicate the section of footage and move the copy to the next higher video track, then use a shape mask to frame the small section that is problematic. This works for the most part except that during the cross dissolve at the beginning and end of the clip. During the dissolve you can clearly see the shape of the mask as it doesn't 'dissolve' at the same rate as the dissolve on the underlying original clip.
I would imagine that there has to be a simpler way to accomplish this, but it's eluding me.
Thanks,
Chris

If you have to dissolve between composites, which is what you're creating with holdout and edge mattes and keys, you have to merge all the layers into one and then you can apply those transitions. You need to either key all the video you're using, export animation + which will maintain the alpha and edit into your sequence or export selects to Motion with sufficient handles for your dissolves and then import those Motion projects back into FCP.
You could create sequences of any selects, do the key in FCP with your mattes, import those sequences into your master which would also take care of any dissolves. However, Motion has a superior keyer and matte tools over FCP.
At any rate, this involves some organizational strategy over just applying a keyer to a layer in FCP.

How to define validity for RA key

Hi
I want to define validity for RA key. This is available in OKG3 under Edit tab. However, the functionality of "Define Validity" is inactive.
How can we activate the same?
Regards,
Vijay

Hi,
I think Michael is asking how you would define the Filter in the Coherence Console not in Java code.
In the Console you prefix the method name for the filter with an exclamation mark.
In your example you see this
Map (jk): filter f Equals getUserId 'Master'...when you press enter you see the toString of the Filter...
EqualsFilter(.getUserId(), Master)Using an exclamation mark you get a Key Filter like this
Map (jk): filter f Equals !getUserId 'Master'...when you press enter you see the toString of the Filter...
EqualsFilter(KeyExtractor(extractor=.getUserId()), Master)...which you can see has a KeyExtractor.

Text Ring misbehavior with ALT key - Win 7

This may not be a LabVIEW problem, but maybe somebody knows a workaround.
LV 2010.0
I have a text ring, populated with only one item.
I intercept the MOUSE DOWN? event on this control.
Upon that event, I look at the MODIFIER keys (Shift, Ctrl, Alt) and populate the control's menu (STRINGS & VALUES) according to which key(if any) is pressed.
(The point is to offer channels in alphabetical order, or in order of units, or in order of hardware type, etc...)
After populating the menu, the menu pops up and the user sees the list rearranged in whichever fashion.
The user chooses one, and the VALUE CHANGED event triggers removal of the full menu and insertion of the single chosen item.
This worked fine..... until I moved to Win 7.
Now, when I try the ALT option - the menu just flashes and then disappears. The first time you ALT-click, it appears for maybe 0.3-0.5 second and then drops. Subsequent times it just draws the frame and then drops - it's just a blip - maybe 0.1 second.
Clicking on it without ALT works normally, and then the next ALT click will restore the long (0.3-0.5 sec) behavior.
If you release the ALT key during that 0.3-0.5 seconds, the menu sticks and works OK, but that's not something people are expecting to do.
It's not my code at fault: try this yourself:
Place a TEXT ring or a MENU ring on a new panel.
Enter "A", "B", "C" as your items.
without even running the VI, Alt - click on the thing.
In Win 7, it flashes the menu, then takes it away.
I've looked for some Easy Access feature that was turned on by mistake - Mouse Keys, Sticky Keys, Toggle Keys, Filter Keys, they're all OFF.
Is there a "don't be stupid" preference somewhere that I could turn on? Or do I have to switch to another key?
(I'm using ALt, Ctrl, Shift - maybe I could use the Win Key...)

Attached is a VI which shows the SHIFT-ALT-CTRL states when the ring is clicked on.
Here is a JING which shows the behavior: http://www.screencast.com/t/2Xh5loKW
The JING doesn't capture every flash, as the flash is sometimes quick. But it shows some of them. It happens every time.
