Bounds of Selection
Hi,
I need to get the geometric Bounds for selected Images. My document contains multiple items(path, text and group items). I want to get the height and width of the over all selection of the images. How do i get tat??
Regards,
Sudha K
It depends on whether the images are placed or embeded. If placed then make a temporary group of the placedItems and get it's geometric bounds. If embeded then do the same for rasterItems.

Selection without selection bounds
I'm using CS2 so I can't call on selection bounds (which seems to be the preferred method of working with selections)
var sb = activeDocument.selection.bounds;
var sbWidth = sb[2]-sb[0];
var sbHeight = sb[3]-sb[1];
alert(sbWidth + " , " + sbHeight)
So the above code won't work for me
How can I find out (1) if a selection is set (selection width & height = 0?) and (2) find the width and height of said selection assuming that only the rectangular marquee is used (not ellipse or lasso).
CheersI had to find out bounds of selection that could be any shape for my Photoshop Photo Collage Toolkit the selections are image size and shaped alpha channels in the Photo Collage Template PSD file with the names "Image 1", "Image 2", ..., "Image n". I had a heck of a time to come up with a way that worked in CS2, CS3, Cs4 and CS5. After consulting with my good friend Rube Goldberg we can up with a contraption that seems to work. This is not a thing of beauty. Some local functions are not shown for the function name states what it does.
// Get Alpha Channel's width and height Selection Bounds did not work???
makeLayer(); // Make Temp Work Layer
loadAlpha("Image " + imageNumber ); // Load Image Alpha Channel
fillBlack();
activeDocument.selection.invert(); // Inverse
// If image size equals canvas size no pixels will be selected clear will fail
try{
activeDocument.selection.clear(); // One clear did not work
activeDocument.selection.clear(); // Two did the trick
}catch(e){}
activeDocument.selection.deselect(); // Deselect
var SB = activeDocument.activeLayer.bounds; // Get the bounds of the work layer
var SWidth = (SB[2].value) - (SB[0].value); // Area width
var SHeight = (SB[3].value) - (SB[1].value); // Area height
activeDocument.activeLayer.remove(); // Remove Work layer
Where there is a will there is a way. Layer bounds does work...
I needed these selections bounds so I could resize and align placed images to these mapping Alpha Channels and mask any Image overflow.

Using radio button selection in multiple tables
Hello All,
I've got a bit of a design issue and it being a Friday my brain is a bit foggy and I can't seem to figure out a solution.
what I want to do is have 3 tables. The user should only be able to select one line from any of the three tables.
I can do this by having events that clear down selection on the two other tables on any selection of the third, but the select buttons of tables don't really give the UI impression that only one row can be selected. To do this I'd like to use the radio button element.
so
table A
choice - name
(o) - Anne
(o) - Bob
(o) - Charlie
Table B
choice - name
(x) - David
(o) - Ellen
(o) - Fran
Table C
choice - name
(o) - George
Here the entry in table B for David is selected. But any selection of any of the other options should deselected.
My thoughts are to use a radio button ui element, bind the "selected" value to a unique id for each row/table (an attribute of the node element for each table) and the value to a common shared attribute (not table specific).
Any better ideas - and certainly any which would mean I'm not going to have to maintain a lookup table of my unique ids and node elements to find out which one is selected?
Cheers,
ChrisOk - here's how I did it.
I created another lookup table which had a guid and reference to the element.
in the each elements I had a guid which I bound to the key for selection property of the radio button in the table.
I then bound the selected key property to an attribute that was common to all elements.
in my "processing" logic I read the selected key, read the lookup table - and therefore got the reference to the selected element.
Would have been an awful lot easier if I could have used a reference to the element itself as the "key" - but that was required to be a character field.
[image showing radio button selection working across multiple tables|http://i51.tinypic.com/bi79dx.jpg]
End result works quite nicely.

Is there a way to tighten a text bounding box?
Hey all,
I've looked before but never found a definitive answer to this question:
Is there a way to tighten the text bounding box without converting it to outlines?
I work for a screen printer, and want to figure out a way to tighten the bounding box without changing the leading and without converting it to outlines in order to be able to edit said text. We deal with a lot of clients who send us names, that are often misspelled, and after an initial proof need to be corrected. Sometimes we need to center this text to an object.
Illustrator's bounding box, unlike that of Corel (which is our primary program, and won't open AI files) includes the leading below the type, so when you center it, it's not visually centered:
So I guess my real question is is there a way to get the text centered (as seen below) without converting the text to outlines, or messing with the leading, or is there a way to tighten the bounding box?
Thanks in advance!
-KCombat and Dandreu,
You may use this silly way:
1) Tick Edit>Preferences>General>Use Preview Bounds;
2) Select the Type and Effect>Path>Outline Object.
That will reduce the Bounding Box to the actual bounds of the letters so you can centre as you wish.
Remember to untick Edit>Preferences>General>Use Preview Bounds before you get a reverse issue. -
Problem rotating rectangle (selecting corners) after creating with rectangle tool in illustrator
I'm using the latest CC version of Illustrator. When I draw a rectangle using the rectangle tool, I no longer seem to be able to select the corners to resize the rectangle nor does the cursor turn to a rotate icon when I put the mouse just outside the corner. I know that Ai CC treats rectangles differently now, with the live rectangles and the rounded corner options, and the transform box opening automatically. What I'm wondering, and hoping isn't the case, is whether this is this at the expense of being able to go right in and resize using the just the mouse? I know that there is the "Object > Shape > Expand" option, but having to do that for every time I draw a rectangle is time-consuming and adds and extra step that was unnecessary before. I saw a tutorial on Lynda where the instructor drew a live rectangle in CC AND was still able to resize it by grabbing the corner "handle". Anyone know if this is just a setting I need to turn on or something similarly easy, or is it a case of Adobe inadvertently making the workflow longer when trying to make it easier? And yes, I have "show bounding box" selected under VIEW.
MOD indi-go girl,
I am afraid you have come across the Live Rectangle bug which is limited to the MAC versions starting with 10.7 and 10.8, but not 10.9 (Mavericks) or 10.10 (Yosemite). Hopefully, the bug will be fixed soon.
So a switch to Mavericks or Yosemite with a reinstallation might be the way to solve it here and now.
To get round it in each case, it is possible to Expand the Live Rectangles to get normal old fashioned rectangles, or to Pathfinder>Unite, or to use the Scale Tool or the Free Transform Tool.
A more permanent way round that is to create normal old fashioned rectangles, after running the free script created by Pawel, see this thread with download link:

Select multiple boxes at time of Outbound Delivery processing with scanner
Hi all,
I am facing a problem at time of processing outbound delivery. I am bound to select 1 box and its corresponding HU. This reduces productivity of end users. I want to know if there is any possibility to select multiple boxes at one go using a scanner, so as to attach all HU at same time.
Regards,
AjayHi,
This is because plant 2 is processing delivery -2 with reference to sales order.
So when you want to process deliver -1 then same already created with reference to sales order. it means both delivery cant be accessed one time because reference is sales order, so it lock
If you want to pick both at same time,
Then assign one shipping point to both plants, so when you create delivery both item will copy in delivery,then pick both at same time.

Export portion of an Image using Lyr "Bounds"
Hello,
I extract PNG export code using listner and it has following basic steps.
Enumerated PNG filter for an action descriptor.
Put class PNG format
Give image path and alpha channels
Play 'eventSave' over the action descriptor.
Now, this will export entire layer as a PNG. I wanted to export just a part of an image.
Therefore, I have modify above steps as below.
Get layer bounds.
Select are rect using top, left, right, and bottom.
Crop image.
Enumerated PNG filter for an action descriptor.
Put class PNG format
Give image path and alpha channels
Play 'eventSave' over the action descriptor.
Do event playback
But unfortunately above additional steps get huge execution time.
Is there a better way to implement same requirement without playing extra events ?
Since I have image bounds, width and height, should I be able to do this without cropping and play back history?you have to cut out the yellow rectangle and include transparent areas because the java 2d system, jframe, jpanel, paintcomponent only allows square rectangles as far as i know. it looks like you have some manual editing to do with the eraser tool in your favorite paint program.

Proportional Scaling with bounding box does not work
Problem:
When I attempt to proportionately scale objects with the bounding box, by selecting a corner / handle and holding Shift as I drag, it doesn't work.
I'm not doing it wrong or in the wrong order of selection, etc., I've done it this way for years.
Also, Illustrator is persnickity. It HAS occasionally worked, but more often does not.
Restarting Illustrator, my computer, closing Entourage, nothing works.
I read this thread and none of the suggestions work.
http://forums.adobe.com/message/1258725#1258725
Just for reference, these are the instructions from Illustrator manual that I am having issues with.
Scale objects with the bounding box
Select one or more objects.
Select the Selection tool or the Free Transform tool .
Drag a bounding box handle until the object is the desired size.Objects scale relative to the opposite handle of the bounding box.
Do any of the following to control the scaling behavior:
To maintain the object’s proportions, hold down Shift as you drag.
To scale relative to the object’s center point, hold down Alt (Windows) or Option (Mac OS) as you drag.ask,

Checkbox group selected property binding not working
Hi,
I've been through all the threads and tutorials relating to this problem and none of them help.
The Situation
I have a checkbox group which I have bound the items items property to a MySQL database (value field = int, display field = String). I have bound the Selected property to a sessionbean field which is an int[] array.
I have a processValueChange event for my checkbox group which grabs the selected boxes values (ie the int value of the checkbox id). Based on these values it does some other processing.
The Problem
When the page loads everything is displayed ok. When I select a checkbox within the checkbox group the getSelected() method returns the int value of the selected checkbox and perform other processing as necessary... so far so good.
However, when the page finishes processing and reloads the selected checkboxes are not ticked. I'm sure it has something to do with the Selected property of the checkboxgroup but I can't for the life of me work out why. For multiselect objects the Selected property must be bound to an array which I have done with my int[] array. I've tried preloading the array with default values (1, 2, etc) to mimic the int values from the database. I've tried changing the array to a boolean array but this throws exceptions. So basically i'm stuck.
The Source
Session Bean
private int[] extras;
public int[] getExtras() {
return this.extras;
public void setExtras(int[] extras) {
this.extras = extras;
Page JSP
<ui:checkboxGroup binding="#{book_package.extras}"
converter="#{book_package.extrasConverter}" id="extras"
items="#{book_package.extrasDataProvider.options['extras.ExtrasID,extras.Name']}"
onClick="common_timeoutSubmitForm(this.form, 'table:tr:td:table:tr:td:table:tr:td:div:div:table:tr:td:extras');"
selected="#{SessionBean1.extras}" valueChangeListener="#{book_package.extras_processValueChange}"/>
Page Java
public void extras_processValueChange(ValueChangeEvent event) {
// TODO: Replace with your code
getSessionBean1().setExtrasTotal(0);
try {
int[] extra = (int[])extras.getSelected();
int extrasId = 0;
int extraPrice = 0;
if (extra.length != 0) {
for (int i=0; i < extra.length; i++) {
extrasDataProvider.cursorFirst();
do {
extrasId = new Integer(extrasDataProvider.getValue("ExtrasId").toString()).intValue();
if (extrasId == extra) {
extraPrice = getSessionBean1().getExtrasTotal() + new Integer(extrasDataProvider.getValue("Price").toString()).intValue();
getSessionBean1().setExtrasTotal(extraPrice);
break;
} while (extrasDataProvider.cursorNext());
} catch (Exception e) {
log("Exception occurred!!", e);
error("Error: "+e.getMessage());
getSessionBean1().setTotalPrice(getSessionBean1().getPackagePrice() + getSessionBean1().getExtrasTotal());
Any help appreciated.
Thanks.ok, i found the problem. MySQL int value is treated as an Integer in Creator. I changed my SessionBean array from int[] to Integer[] and now it works properly... phew!!!

Text box Vertical Justification greyed out in CS4
Does anyone know why the ability to vertically justify my text boxes is disabled? It is only in this one document (although, I think I remember this occurring in another). The option is greyed out in the Text Frame Options window and will not allow me to click on the options in the tool bar. This is rather frustrating and can't for the life of me figure out how to fix it. Anyone else experience this or know how to fix it?
Thanks,
MelPrior to CS5 you can't vertically justify any frame in which the text area is not rectangular. Not only can text wrap change the shape of a text area, but so can corner effects (adding enough inset will get past this), and of course the use of non-rectangular frames.
Thanks, Peter. I had already adjusted the top inset enough to achieve the look I was looking for. That's good to know about the corner effects. That is actually when I experienced this before and used insets to achieve my desired look then, too.
Peter's pointing out that you could inadvertently move just one of the corners with the direct selection tool and have a frame that isn't a rectangle and then you loose the text box vertical justification option. If you are on OSX you can use this script to square up a selected skewed box:
tell application "Adobe InDesign CS3"
set {a, b, c, d} to geometric bounds of selection
set entire path of path 1 of selection to {{b, a}, {d, a}, {d, c}, {b, c}}
end tell -

* The RectShape class defines a simple rectangular shape object.
* It tracks its bounding box, selected state, and the canvas it is being
* drawn in. It has some basic methods to select, move, and resize the
* rectangle. It has methods that draw the shape in the selected or unselected
* states and updates the canvas whenever the state or bounds of the rectangle
* change. The code that is there works properly, but you will need to extend

Still having navigation problems and need help with how to debug
Hi,
I've been porting over a servlet project to JSF and I'm still having navigation problems. I thought the problem might have been because the original project used HTML frames and so the "from-view-id" JSP defined the frame/framesets and the specific JSP that does the submit (and so is named in the "from-view-id" is never defined in a "to-view-id" attribute). I've now switched to using an IFRAME, and that resolves that problem. So now the JSP is defined in a "to-view-id" attribute and it includes an named IFRAME that can be used as a target. I press the submit button and I get not the JSP expected butinstead the same JSP displayed inside its own IFRAME.
Here is the code for the submit. I've simplified it as much as possible with a static action (originally it was a call to a method) just to try and get things to work. This is the current version:
<h:commandButton value="View Alias" action="foo" styleClass="select" type="submit" />Here is the navigation rule in faces-config.xml. Again, the problem is that SelectManager get redisplayed in the IFRAME instead of display.jsp.
<navigation-rule>
<from-view-id>/SelectManager.jsp</from-view-id>
<navigation-case>
<from-outcome>foo</from-outcome>
<to-view-id>/display.jsp</to-view-id>
</navigation-case>
</navigation-rule>I have also tried it without the "from-outcome-value" which I presume means that the "to-view-id" gets displayed unconditionally and it still fails. Any ideas on how I can debug this? (I'm using GlassFish if that's important to know)

Linfield CollegeRaymond, The real trick is avoid doing technical things when coming down with the flu (I should also add that I'm a JSF newbie). Reading your original message this time I see what you're suggesting and found a conversion error although I don't understand it. Here's the code (including the <h:message/>):
<h:selectOneMenu value="#{members.dcodes}"
style="color: #7f0000" id="selector">
<f:selectItems value="#{members.departmentList}" />
</h:selectOneMenu>
<h:message for="selector" style="color:white"/>And here's a snippet of the generated HTML:
<select id="j_id_id26:selector" name="j_id_id26:selector" size="1" style="color: #7f0000">
<option value="aad" selected="selected">Academic Advising</option>
<option value="aaf">Academic Affairs</option>
<option value="adm">Admission</option>
<option value="up">Upward Bound</option>
</select>If I select "Admission" for example, the error I get is:
Conversion Error setting value 'adm' for 'null Converter'.Since everything is a String value, I don't get the error. Could someone please enlighten me.

Adding a Text Frame to an Existing Group
I have belatedly discovered another difference between CS4 and CS2 -- I don't know whether this started with CS3 or not; I think perhaps it did.
When you want to add a text frame to an existing group (which means create a new one within group), it's fairly straightforward unless the group is inline to a story. Then the new item gets added at the wrong place (I suspect what actually happens is that it always used to get added at the wrong place and then moved to the specified coordinates; but in CS2 and earlier, there was no automatic updating of the screen so the coordinates worked, but in CS4, the addition of the new frame moves the inline and so the coordinates you're aiming for are no longer correct). I worked around this in the following script by changing the anchoring and then changing it back -- I'm not entirely sure that this is foolproof, but it works on the job we're using it for.
//DESCRIPTION: Add New TF to Parent Group of Selected TF
(function() {
if (app.documents.length > 0 &&
app.selection.length === 1 &&
app.selection[0].parent instanceof Group &&
app.selection[0] instanceof TextFrame) {
var group = app.selection[0].parent;
if (group.parent instanceof Character) {
// we have an anchored group. Make sure it is custom while processing
var origAncState = group.anchoredObjectSettings.anchoredPosition;
group.anchoredObjectSettings.anchoredPosition = AnchorPosition.anchored;
var bounds = app.selection[0].geometricBounds;
var newTF = group.textFrames.add({geometricBounds:bounds});
newTF.move(undefined, [0, -1]); // offset a pica -- or whatever the units are
if (origAncState !== undefined) {
group.anchoredObjectSettings.anchoredPosition = origAncState;
app.select(newTF);
} else {
alert("Please select a text frame in a group.");
