How to change IMAQ ROI color while adjusting handles

I have an application where a user must draw a rotated rectangle box around an object. I'm using an color overlay to highlight the box, but when the user is adjusting the roi handles, the box color becomes gray. The images i'm working with are gray scale images and it makes it difficult to adjust the rotated rectangle box when they are virtually the same color. Is there any way to change the color of the roi while it is being adjusted?
Thanks,
Pete

Hi pbartko2,
You can change the color of the ROI while it is in place, but there are no settings to change the color while the ROI is being moved. This will always be the default color of grey. You could post this as a suggestion on our Idea Exchange. Ideas voted up on the Idea Exchange are taken into consideration for previous releases. Unfortunately at the moment there isn't an easy way around this issue.

Hi, I'm working on a document in PAges 09. Any idea on how to change the document color? I want it black instead of white.

Nichelle,
You must add your own background object, and then make it Black.
Insert > Shape > Rectangle
In the Wrap Inspector, set to Floating.
In the Graphic Inspector, set Stroke to None and set Fill to Black.
Grab the corners of the document and stretch the document to cover the entire page.
Back in the Wrap Inspector select "In Background".
Format > Advanced > Move Object to Section Master.

How do change the text color in the variable screen ?

Hi Experts ,
I would like to know about , How do change the text color in the variable screen ?
Using web templates (Analytical) can get the output. It has the variable screen contains 6 fields (Company code, Country , Region , COB, Plant and Purchasing Group). I want to make RED color text on Plant. Please help me .
Thank you ,

Hi,
I am looking for nearly the same. What I have found is that it seems to manipulate the SAP theme that is used in standard when template is executed in the portal. Just display the source code of the HTML and there you will see the included SAP theme (normally SAP_TRADESHOW). Then you have to go to the SAP portal and change this stuff. But for that you have to know where to find it and what impact this change has.
I am not pretty sure if this is the right way. But as I want to change the standard layout of a whole template to a customer specific layout I think there is no other way in BI7.0.

How to change table border color in DW CS6

I need to know how to change the color of the border around my tables in Dreamweaver CS6. I saw a article on how to change it on http://forums.adobe.com/message/4451812, but i really couldnt follow because im just starting out using dreamweaver and i dont know anything about code. Is there a simple way to change the border color or can you give me a basic step process on how to change the border color in the code?

Just an FYI, nobody uses Table-based layouts anymore. It's much better to use CSS for layouts. Only use tables for tabular data like spreadsheets and charts.
Dreamweaver has a bunch of pre-built CSS Layouts for you to use as starter pages. Just go to File > New > Blank page > HTML. Pick a layout from the 3rd panel and hit Create button. See screenshot below.

How to change the document color mode(RGB to CMYK)?

Kindly advice me how to change the document color mode(RGB to CMYK) via scripting in "illustrator cs3".
Thanks.

Somebody wrote and posted this a couple of years ago.
// Duplicate the selection from the active document into a new document.
// To invoke the JavaScript debugger, remove comment delimiters
//$.level = 1; debugger;
var newItem;
var docSelected = app.activeDocument.selection;
if ( docSelected.length > 0 ) {
// Create a new document and move the selected items to it.
var newDoc = app.documents.add();
if ( docSelected.length > 0 ) {
for ( i = 0; i < docSelected.length; i++ ) {
docSelected[i].selected = false;
newItem = docSelected[i].duplicate( newDoc,
ElementPlacement.PLACEATEND );
else {
docSelected.selected = false;
newItem = docSelected.parent.duplicate( newDoc,
ElementPlacement.PLACEATEND );
else {
alert( "Please select one or more art objects" );
It should give some ideas about how to proceed.

How do I change the stroke color while retaining the fill color using eye dropper in Illustrator?

I have a question regarding illustrator.
Let's say I have a circle with blue fill and red stroke. And I place an image in the illustrator file. Now I want to change the red stroke of my circle to let's say a purple color by sampling the color from the image.
How can I achieve that with a eye dropper tool? Every time when I try to sample a color from the image, the whole circle will change to purple instead of just the stroke?
I have tried multiple key combination, shift, alt, ctrl but they all don't work.
Cheers, Venn.

What you were saying is essentially what Mike's screenshot is all about?
Deselect Focal Fill on Picks Up and Applies.
I don't see how disabling them will help?
If you have an image, Illustrator reads it as a transparent shape without any appearance attributes.
Now I have a shape with a stroke, I want to change the stroke color by sampling the colors on the image.
You can't do that with the eyedropper because the image doesn't have a stroke.
Eyedropper only picks and applies appearances.
So I guess you can't do this in Illustrator from the beginning.
The eyedropper isn't built for that.

How to use IMAQ extract color panel in a LabView file?

I want to change a color image into a greyscale image. Therefore I want to use the function IMAQ extract color panels but I don't know how to insert it in my LabView application.
Please, can anyone give me some advice ?!!!
Thx, Birgit

Birgit,
If you want all of the color planes, you can use IMAQ ExtractColorPlanes. Allocate an 8-bit image for each of the color planes. Wire the original color image and each of the 8-bit images for the color planes on the left and bottom of the vi. The outputs on the right side will be the same images, and they will each contain the desired color plane. The input at the top of the vi controls which color planes are extracted (RGB, HSI, etc.) Grayscale will probably be the I plane in HSI.
If you just want a grayscale image, use IMAQ ExtractSingleColorPlane instead. Wire the color image to Image Src, and wire an 8-bit image to Image Dest. Select the color plane using the top input, and it will come out on the right side.

How to change the semantic color of entire rows in a table.

Hi, in the past I already managed to change the semantic color of a cell by a condition (for example all the cells with negative number -> I set negative semantic color)
My question is how can I change the semantic color of the entire row where this cell belong, and not only the cell. Im using NW2004.
BTW, Im not a java programmer, neither a Webdynpro expert, just an ABAP Programmer. So try to be very explicit, Thx.

Rodrigo,
You can just bind correspondign property of every cell editor (TextView) of every column to the very same context attribute. Next, when you change attribute value for certain elemnt, the whole row (every cell editor in row) will get same value.

How to change the background color of a sequence?

I'm using Premiere Pro CS5 on Win7 x64. I've imported a JPEG that's a different size than my 1920 x 1080 frame. The background of this JPEG is white, but the background of the sequence is black (by default), so the borders of the JPEG make it stand out. I want the JPEG to blend into the sequence background by making the sequence background white. How can I change the sequence background color? Thanks.

Jim and Ann are correct. I can see where someone used to After Effects might ask that question though because in AE you can change the background color of the composition. Same with Photoshop.
However, I think it would confuse things if changing the background color were to be allowed in Premiere Pro. Black tells me something. I suppose white could tell me the same thing, but at this time it is not possible in Premiere Pro.
