Change image size dynamically in BIP report

Can we change the size of image dynamically in bip report. If yes can I get some doccument or samples on it.
Thanks
Aj

I am doing small POC
I have a rtf template with three sample images on it with three different sizes for 1” by 1” , 3” by 3” and 5” by 5”.
I have a standard size of 2” by 2” image in my server (Could change size in future depending on req)
Now when I run the report the template should call the standard image from server and replace the sample images on the rtf and show the the standard image in three different sizes.
Pls let me know if i am missing something

Change Slideshow Size Dynamically

Wanted to see if I can change the Slideshow size while it plays using:
http://labs.adobe.com/technologies/spry/articles/element_selector/index.html
The factory script shows an error; (I added div.content and then copied and changed the content class).
<script src="includes/SpryDOMUtils.js" lang="javascript" type="text/javascript">
<script lang="javascript" type="text/javascript">
function myFunction(){
   Spry.$$("div.content").addClassName(".contentCopy");
</script>
I was trying to change the class: .content; width (smaller)
Can this be done?

Sorry, I led you up the garden path. The following will work
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">

    height: 150px;

function myResize() {

Change rectangle size animation

Hi I've got this showRect method which draws a rectangle, but I need to animate the rectangle: make its heigth grow from zero to a fixed value.
public void showRect(int x, int y,int rectWidth,int rectHeight)
Graphics2D g = (Graphics2D) getBufferStrategy().getDrawGraphic();
try
if (g!=null)
g.setPaint(Color.ORANGE;
g.fill(new Rectangle2D.Double(x, y, rectWidth, rectHeight));
finally
g.dispose();
To make the rectangle grow I did this:
for(int i=0;i<500;i++){
fs.showRect(800,100,300,i);
fs.updateScreen();
Thread.sleep(20);
and it works fine but as the y axe grows to the bottom of the screen so does my rectangle and I need the rectangle to grow to the top of the screen and can't find how to make it grow in this other direction

This code
for(int i=0;i<500;i++){
fs.showRect(800,100,300,i);will change the height of the rectangle from zero to 500. The top of the rectangle is determined by "y" which is not altered in your code. If you switch from Rectangle2D to Rectangle there is a "grow(int x, int y)" method available.

How to change window sizes dynamically in smartform

Hi,
Dear ABAP Experts,
I need to show different materials current sales by comparing previous years sales (month wise) as a table and their difference in the form of chart( diagram). Can anyone share how to draw chats(rectangular boxes) in smartform.
Please can any one tell me how to pass dynamic coordinates (left margin, width, upper margin and height) to create window. If I know this one I can solve my problem.
Thanks in advance,
Meeravali Shaik.

hi Raju,
You can do onething. Create a variable in global defination of charcter lenth 1.
when you are selecting your address on the basis of address number. suppose we have two address add1 and add2.
if you get add1 set this variable 'X'.
otherwise set it 'Y'.
Now create two text node.
in one text node put your add1 and in other one put add2. in text node yyou will get tab conditions.
Put the condition varible = 'X' for add1.
and 'Y' for add2.
so it will execute one the basis of that condition and print the one of the addresses u have.
Hope this will help you out.
Reward if useful.
Regards,
Azad.
do remember to clear the variable after printing.

Can I change the size of the application stack icons?

I have an application folder on the right-hand side of the dock, I set them to be opened as 'stack'.
When I click the application folder on the dock, it will show me many icons of applications, those are huge.
I'd like to shrink it a little bit, since I can browse more apps at a time, but how can I do?
Thanks in advance!

V.K. wrote:
no, you can not change the sizes of icons you get when you click on a stack in the dock. there is no way around this. this question is asked pretty frequently though and it looks like a nice feature to have. you can leave apple feedback requesting it
http://www.apple.com/feedback/macosx.html
P.S. do note that there is a scroll bar on the right when you click on a stack and you can use that to scroll through the stack.
Thank you V.K., I've sent them my feedback!

Dynamically change in size of the custom container using ALV GRID (OOPS)

Hi Gurus!!!!
I have an issue with the output of the report which is developed using ALV GRID (OOPS). I have used the custom container occupying full screen (Screen painter). When I execute the report using my PC the output displays report as expected in full screen. The problem is when we execute this report in 19 INCH monitor then there is always gap below the report.
As per my understanding we should have a code to change the size of custom container dynamically.
Please suggest some help on this.
Thanks,
Hemal Shah

Hi,
If you set the attributes, Resizing - Vertical and Horizontal for the customer container, than system will resize the size of the custome continer as per the resolution.
Hope it helps,

Rectangle size changes from what I typed?

I'm using Illustrator CS 5 on snow leopard, when I make a new path with the rectangle tool, choosing a size in the dialogue window, say 10"x10" when i look at the rectangles size in the transform window along the top of the screen it says my rectangle is 10.0139" x 10.0139", now if I type 10 by 10 into the field again it stays 10 x 10. Why does it do this and how can I fix this?
Thanks
Marcus

Merrill,
To me it looks like Edit>Preferences>General>Use Preview Bounds being ticked.
A integer inch rectangle is an integer pixel rectangle so there should be nothing to change.

Yes - click on the themes button in the toolbar and select the new size and type - depending on your selection some text may not fit the new theme - usually everything is ok

Dynamically change stage size on runtime

Hi everyone,
I need to change the stage size dynamically.
When i try to do this............
size_mc.onRelease = function(){
    trace(Stage.height);
    Stage.height += 100;
    trace(Stage.height);
it comes always the current stage size.
Thanks in advance

You cannot change the width and height properties of the Stage using code--it must be done in the editor. The width and height values can represent different things depending on the value you set for the scale mode, but you cannot reassign them to different values dynamically.
The solution just offered to you is under the same rules, the stageWidth and stageHeight values cannot be assigned using code, but that code is AS3 code so it will not fit in your AS2 design in any case.
The same goes for the followup offered in AS2. You will notice the stage size is not being changed... it cannot be. This is just a full screen design solution, but is not a soltuion to changing the stage size. The stage size can only be changed manually in the authoring environment. I don't know that the offering is answering what you are really trying to do, but it is not answering the titled task of dynamically changing the stage size
