How to get these lines/effect

Hi guys.
Please, could you help me a little? I am on this simple project where I have to make something similar to this:
http://www.video.terramedia.lt/downloads/lines.jpg
the thing is - I need to animate the center of these lines (anchor point), and when I move that center, lines bend in some manner, if the center of lines is in the center of the screens - lines become straight.
Please, help if possible.
Appreciate any input.

My first thought would be to use an expression to drive the angle property of the twirl effect applied to an adjustment layer.
I'd make your line from a solid, possibly with a mask. Call it something like MasterLine. Move the anchor point to the far left center of the layer.
Then I'd add an adjustment layer with Twirl. Tie the twirl center to the position of your MasterLine layer with an expression. You can simply create this expression with the pickwhip.
Then I'd apply the following expression to the Angle property:
zerox = width/2;
zeroy = height/2;
lineCenter = thisComp.layer("Red Solid 1").transform.position;
bend = [zerox, zeroy] - lineCenter;
distort = bend[0] - bend[1];
distort
After that I'd duplicate the Master Layer and offset the rotation of the duplicates 5º or 10º until you had you pattern established. You could either parent each of the duplicates to the MasterLayer (should probably add an 01 to the name so that the duplicates will be numbered) or use expressions to tie the position of each of the duplicates to the master. You could even use the layer index to automatically rotate each of the duplicates .
I think this should work. At least it should get you started.

How to get 2nd line in smartforms using template

how to get 2nd line in smartforms main window using template. i have also defined loop .

if possible can you try with the TABLES..
Put one TABLE in your MAIN window
create table lines as per your requirment...consider all lines like 6 for header, 1 for main, 1 for total
Now, you will find three section under the tables: header, main, footer...
in header section, create a table line, assign one of the proper lines from the line types.. repeat for your all lines.
in main section, you can access your data form the loop.
the footer secion will be called, just after the main will be finished.

How to get these values?

This sample output of trcsess shows the consolidation of traces for a particular
session. In the following example the session index and serial number equals 21.2371.
trcsess session=21.2371My question is: what are session index and serial number here? How to get these values?

As per the tuning doc:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/sqltrace.htm#i20110
You get these values from the V$SESSION view.
Session Index = SID
Serial number = SERIAL#

Hi Ravi,
Line -
Use a SMATSTYLE for this purpose.in the smartstyle create a paragraph or character with underline atribute.Then call the smartstyle in the text.

Why am I getting these lines?

Hello everyone.
I have asked this before here and was helped out very well. I have followed the same steps I was told before which worked before but for some reason is not working now. Here is a clip of a Demo I made for a client but I keep getting these lines when someone moves. http://www.simplycaptivating.com/hddemo2.mov
Now someone on this forum had previously helped me with this problem on a diffrent clip, and it worked great. But now when I follow those same steps with this clip I still get the lines. Does anyone have a clue as to why?
Thanks for the help.

What you say sounds like an interlacing problem - interlacing shows up on computer monitors as it is designed for TV. Interlacing is usually much more noticeable during high movement.
However: I usually see interlacing on my monitor, and I don't see it in your file. The only lines I see are vertical ones in the chandelier shot, but I think they are light ray artefacts (and they look fine, a bit like rain if anything).
If it is the interlacing, then you need to apply a deinterlace filter. However if your friends plan to watch it on DVD on a TV, it may not need it. Have you tried burning it as a DVD and watching it on a regular screen?

How to get file line count.

Hey guys,
How to get file line count very fast? I am using BufferedReader to readLine() and count. But when dealing with big file, say several GB size, this process will be very time consuming.
Is there any other methods?
Thanks in advace!

What I'd do is you create an infofetcher, register a listener, implement gotMore() and have that scan for '\n'
Some might suggest getting rid of the listener/sender pattern or use multiple threads to make ii faster. This might help a little, but only if your I/O is super-duper speedy.
you are welcome to use and modify this code, but please don't change the package or take credit for it as your own work.

How to get this skin effect on a black model?

hello everyone!!!
i was wondering if anyone knows how to get this final effect on a picture with a black model?

1. Original image
2. Convert to grayscale, then back to RGB
3. Approximate color of sample
4. Curves to add contrast
Final. Dodge selected quartertones
If desired, add a very, very slight noise. Not in image here. (Add'l layer: Gaussian, Mono, very low opacity)

I'm really disappointed with new 5 update. No music, No photos, No videos, lost all emails. Anyone know how to get these all back? Yes, I have synced and synced and synced. Help

I'm really disappointed with new 5 update. No music, No photos, No videos, lost all emails. Anyone know how to get these all back? Yes, I have synced and synced and synced. Help

Hopefully it isn't too late for this but: before performing an update it is really best if you close all apps (double click the home button, click and hold on one of the apps that appears at the bottom of the phone until the red minus sign appears and then tap the minus sign until all apps are closed) and then turn the phone off by holding the standby button until the slider saying "slide to power off" appears and slide it to turn the phone off. Then turn the phone back on and hook it up to your computer to sync and perform the upgrade. This also helps if you do this before performing syncs too. I had problems with an iPod previously where it would fail to backup before sync most times, but have never had a problem with updates or syncs since I started performing this procedure. Unfortunately, your pre-update backup may have failed and the data in your apps might be gone, but you could try to restore your phone. If I remember correctly how to do this, you connect it to your computer and check for updates. It should say you're up to date, but have an option to restore the phone. If it does, I'd try that. It may also have a "restore from backup" option you could try.

How to get a line break

Hi All,
How do I get a line break within a particular field?
My DB structure is that I have 4 columns address_line_1, address_line_2 and so on. I cannot select them as different fields because all of them can be null, in which case i pick it from internal_address_line column.
I use:
SELECT DECODE(address_line_1, NULL, internal_address_line, address_line_1 || ', ' || Address_Line_2) as ADDRESS
But instead of th comma separating the 2 address lines I want a line break so that 2 address lines come in 2 separate lines in the output.
It doesn't allow me to use chr(10) as a line break and gives an error
I'm using Reports 2.5
TIA
Naveen

Yes, true.
How about setting up the sections as:
Section 1 Introduction ('Section num space introduction' in this example - tab may be better)
Then generate the Contents.
Then do a GREP find/change on the document after the contents:
This will add a forced line break and tab after each section number... You might want to specify a para style in the Find Format box too, so that references to Section xx in body text are not altered.
If you update Contents after this, you will get the line break and tab in the Contents too.

How to get these units?

Please follow the steps:
1. Edit->Preferences->Units & Display performance... to bring the dialog.
2. In "Units" group, we can change units for "General", "Stroke", "Type" and "Asian Type".
We can use AIUserSuite::GetUnitsString to get the general units, but how to get the other three units? Does anybody know it?
thanks

Hi,
You can get these units with AIPreference Suite.
long units;
sAIPreference->GetIntegerPreference(NULL, "strokeUnits", &units);
sAIPreference->GetIntegerPreference(NULL, "text/units", &units);
sAIPreference->GetIntegerPreference(NULL, "text/asianunits", &units);
These suffix strings were found in AIPrefs file.
