Get the Coordinates of a Character in a TextArea

Is there a way to determine what the coordinates of a given
character are in a TextArea control? One project I'm working on
presents a chunk of text cut off at some number of characters,
followed by a LinkButton control (e.g., to view "more"), and I'm
having trouble figuring where to place the LinkButton control
without knowing the coordinates of the last visible character of
the TextArea. Anyone dealt with this one before?
Thanks in advance...
Chris

Hm, thanks, but that just places the LinkButton next to the
TextArea control, beside and outside of it, not "inside" (or really
over) it, as my example should've implied.
I think I've found a workable solution -- see below, where
myCanvas is some Canvas control already defined in MXML somewhere,
and myText is a Text control already defined (and populated) as
well:
var numberOfLines:int =
myText.mx_internal::getTextField().numLines;
var lineMetrics:TextLineMetrics =
myText.getLineMetrics(numberOfLines - 1);
var targetX:int = lineMetrics.width + 10;
var targetY:int = (numLines - 1) * lineMetrics.height;
var myLinkButton:LinkButton = new LinkButton();
myLinkButton.label = "More...";
myCanvas.addChild(myLinkButton);
Still testing, but TextLineMetrics seems to have done the
trick.
If anyone has a better approach, let me know! Thanks much.

How to get the coordinate of any character in just a single text frame?

I am using Illustrator CS5. Better solutions in c# language.

Hi,
According to your description, my understanding is that you want to get the groups name of a specific user using Client Object Model PowerShell in SharePoint 2010.
We can loop the site group collection and the users in each group and then check if the user exists in the user collection.
ClientContext clientContext = new ClientContext("http://sp/sites/mysite");
GroupCollection collGroup = clientContext.Web.SiteGroups;
clientContext.Load(collGroup);
clientContext.ExecuteQuery();
User usr = clientContext.Web.EnsureUser(@"contoso\administrator");
clientContext.Load(usr);
clientContext.ExecuteQuery();
foreach (Group group in collGroup)
UserCollection collUser = group.Users;
clientContext.Load(collUser);
clientContext.ExecuteQuery();
foreach (User user in collUser)
if (user.LoginName==usr.LoginName)
Console.WriteLine(group.Title);
Console.ReadKey();
For PoweShell command, you can convert the code above to PowerShell Command.
Here is a detailed article for your reference:

PhotoShop Automation PlugIn: How do I get the coordinates of a polygonal selection?

Hi.
I try to get the coordinates out of a selection, but I can't find out how to do that.
I tried to convert the selection into a path and get the coordinates from the path. That doesn't work either.
Can somebody give me a list of parameters inside the action descriptor of keyPathContent in classPath? I assume that the point infos are located there...
Thanx in advance,
Christian

found the answer myself. It might be helpfull to others.

Getting the coordinates of an overlayed rectangle or point

I have drawn a rectangle or point on an image using the Tools and I now want to get the coordinates of the rectangle or point I have just drawn. How do I do this?

bep -
To do this, use the Regions property on the CWIMAQViewer object, and assign it into a variable of the type of the ROI (in this case, a rectangle). Here's an example:
Dim rect As CWIMAQRectangle
Set rect = CWIMAQViewer1.Regions(1)
The rect variable should now contain the dimensions of the rectangle drawn.
Let me know if you have problems with this. Thanks!

How can I get the coordinate in the layer coordinate system while doing the iterate?

I found that the position(x,y) the iterate function tell me is not right sometimes.
Actually,it happens when the top of the layer is negative. The "y"is in the comp coordinate system(maybe?) but not the layer.In another word, the position with y=0 is not the top.
More specifically, I have got the color map of a layer. I am able to get the color of any pixel in the layer. But I can't set the color one for one when I use "iterate",because there is an offset.
Am I supposed to get the offset? Is there any way to access the whole layer directly if I use iterate function?

so indeed it's the offset at play.
AE will diminish the buffer at 20% increments, and not for each pixel that
goes out of sight. it's not really in relation to the upper left corner,
it's all about what part of your layer buffer is out of sight.
there's also an "iterate offset function". check it out. perhaps it will
save you some trouble.

SDO_ORDINATES how to get the coordinates?

Hello,
how can i get the individual x1,y1 and z1 coordinates of a box? when i use in an sql statement sdo_ordinates i just get an object sdo_ordinate_array. But how can i filter out the coordinates? To explain what i want to do here a pseudocode sql-statement:
select min(v.shape.sdo_ordinates.x1),min(v.shape.sdo_ordinates.y1),min(v.shape.sdo_ordinates.z1),max(v.shape.sdo_ordinates.x1),max(v.shape.sdo_ordinates.y1),max(v.shape.sdo_ordinates.z1) from veith.voxel v
Is there a way to get an sql-statement that gives me the min and max x1,y1 and z1 from a table and also a statement where i get the x1,y1 and z1 value from all tableentries? For any help thanks in advance.
Greetings,
Markus Veith

Markus,
If you are using 9i there are two functions: sdo_geom.max_mbr_ordinate and sdo_geom.min_mbr_ordinate which will return either the min or max ordinate values in a layer.
If you are using 8i, you will have to write a sql block or procedure to compare the x ordinates or y ordinates and retrieve the min or max values.
Hope that helps.

Getting the coordinates of 1 bufferedimage inside another buffered image

hi, i'm kinda new to this.
is there a way to get the starting x and y coordinates of 1 bufferedimage inside another bufferedimage
let's say this is bufferedimage 1
http://img293.imageshack.us/i/oracle.png/
and this is bufferedimage2
http://img38.imageshack.us/i/buffered2.png/
i would like a method to return the x and y coordinates of image1 inside image2
is there anyway to approach this?
or was there a prewritten method?
thanks

The problem is that the two rectangles have points in common. When the CWIMAQVision.RegionsToMask is done, it sets any point that is in any region to a non-zero value, and all other points to 0. So, when the CWIMAQVision.Label is done, it sees one big rectangle of non-zero values, and labels that (and so the CWIMAQVision.Quantify sees the one rectangle as well).
The easiest way around this problem (if the rectangles must have points in common) is to only make one region active at a time, so CWIMAQVision.RegionsToMask will only use that region to create the mask image, and then call CWIMAQVision.Quantify twice. So, the code would look like this:
Set pMaskImage = New CWIMAQImage
pMaskImage.Type = cwimaqImageTypeU8
Me.CWIMAQViewer1.R
egions(1).Active = True
Me.CWIMAQViewer1.Regions(2).Active = False
Me.CWIMAQVision1.RegionsToMask pMaskImage, Me.CWIMAQViewer1.Regions
Me.CWIMAQVision1.Label pMaskImage, pMaskImage, avgPixelVal
Me.CWIMAQVision1.Quantify Me.CWIMAQViewer1.Image, globalReport, regionsReport, pMaskImage
dblROImean = regionsReport.Item(1).Mean
Me.CWIMAQViewer1.Regions(1).Active = False
Me.CWIMAQViewer1.Regions(2).Active = True
Me.CWIMAQVision1.RegionsToMask pMaskImage, Me.CWIMAQViewer1.Regions
Me.CWIMAQVision1.Label pMaskImage, pMaskImage, avgPixelVal
Me.CWIMAQVision1.Quantify Me.CWIMAQViewer1.Image, globalReport, regionsReport, pMaskImage
dblSurrROImean = regionsReport.Item(1).Mean
Let me know if this gives you problems.

How do I get the coordinates of the text block (TextFrame) help me please!

Dim myApp As New Illustrator.Application
Dim myDoc As Illustrator.Document
myDoc = myApp.ActiveDocument
Dim textRef = myDoc.TextFrames.Add
For Each ArtPageItems In myDoc.PageItems
If TypeName(ArtPageItems) = "TextFrame" Then
'========It is necessary to obtain the coordinates of the text block and move closer to the object (ie the text)============
Else
End If
Next

Hi Todd, you're welcome, please explain better, I don't understand the question.
are you trying to "move" a textframe (Dim textRef = myDoc.TextFrames.Add) closer to other text frames? or do you want to "zoom" to this textframe?

How can I get the coordinates to draw a line?

Hi,
I want to draw a line. Here is a part of my Quell-code.
public class Map extends JFrame {
public Map() {
super("Map");
setSize(340, 340);
MapPane map = new MapPane();
getContentPane().add(map);
class MapPane extends JPanel {
public void paintComponent(Graphics comp) {
Graphics2D comp2D = (Graphics2D)comp;
comp2D.drawLine(0,0,340,340);
Now, the line begins exactly top left in the edge, but ends not exactly down right in the edge of my Frame. Is there any possibility to determine the exact coordinates of the frame. I thought, if the size of the window is set by the setSize-Method to (340,340), the line ends exact
in the edge (down right). See: comp2D.drawLine(0,0,340,340).
Can somebody give me a piece of advice, please?
Thanks, joletaxi

Have you tried the getWidth() and getHeoght() methods to determine how long the line should be?

Help! Getting the index of a Character from the Characters collection

so, in a script i need to remove the text from the begining of the paragraph until the first tab (or dot or colon or "something") charater as simple and as fast as posible.
i was hoping for something like
myText=myParagraph.characters.itemByRange(0,"\t");
myText.remove();
Ofcourse i can use grep, but it has it's problems, and i was hoping i don't have to (especialy since the script will have to do this for 400+ times.
Any help?

Vamitul
I don't know if that's the way do go about it but this is what you are looking for.
myParagraph=app.selection[0].paragraphs[0];
myText=myParagraph.characters.itemByRange(0,myParagraph.contents.toString().indexOf("\t"));
myText.remove();
To delete until the tab not including it use myText=myParagraph.characters.itemByRange(0,myParagraph.contents.toString().indexOf("\t") -1);

How to get the x1,y1 and z1 coordinates out of an sdo_geometry object?

Hello,
i have stored several boxes into an sdo_geometry object like the following:
mdsys.sdo_geometry(3003,null,null,
mdsys.sdo_elem_info_array(1,1003,3),
mdsys.sdo_ordinate_array(x1,y1,z1,x2,y2,z2)
now i would like to get the x1,y1,z1 coordinates from the boxes. how can i get them with a simple sql-statement?
When i do "SELECT v.shape.sdo_ordinates ..." then i get a sdo_ordinate_array. But how can i get only the first coorinates?
I know how it works to get x1,y1 and z1 over a java-prog. But i want to get them with a sql-statement as i also want to get the min and max x1,y1,z1.
Hope there is anybody that can help me. Thanks in advance.
Markus Veith

You can get coordinates from an SDO_POINT_TYPE as follows:
SELECT t.GEOMETRY.SDO_POINT.x,t.GEOMETRY.SDO_POINT.y
FROM TABLE T
(where geometry is the geometry column and table is the geometry table, note
that a table alias must be used.)
Getting the coordinates from the SDO_ORDINATES is a little trickier.
You'll need to use a loop in PL/SQL, eg:
SET SERVEROUT ON
DECLARE
i number;
j NUMBER;
BEGIN
FOR sel IN (SELECT <geom_column> FROM <geom_table> WHERE ROWNUM < 10) LOOP
i := 1;
while i < sel.<geom_column>.sdo_ordinates.count LOOP
j:= sel.GEOMETRY.sdo_ordinates(i);
dbms_output.put_line(j);
i := i + 1;
j:= sel.GEOMETRY.sdo_ordinates(i);
end loop;
dbms_output.put_line(j);
END LOOP;
END;
This will print the SDO_ORDINATES to the SQLPLUS screen, put a WHERE clause to reduce output.
To use these values in a query, put them in a cursor.

Get instantly the coordinate of end and start point of line, when moving it

The coordinate of drawString()

Guys,
If I use Graphics2D to draw a String, how can I get the coordinate of the last character?
For example, If I:
Graphics2D comp2d= new Graphics2D (comp);
comp2d.drawString("Hello the world", 100, 100 );
How can I get the coordinate for the letter "d" as in "world"?
Thanks in advance!

try using the FontMetrics class
it has methods like stringWidth() and charWidth()
these would be helpful
