Display Image Behind Other Objects

I have an image displayed in my application via a class extended from Panel.
new ImagePanel(img);
it displays alright as long as it remains compartmentalized.
I would like it to display behind my JButtons on the same Panel where they reside. I think I need to paint the background of the Panel containing my buttons with the Image

super.paintComponent(g);

IDCS3 Mac Applying effects changes colour of images and other objects

Something strange happening in InDesign CS3. Hope someone can help me.
When I apply an effect such as drop shadow to an object the colours of all the other objects on the page change. When I say change I mean almost like converting profiles (e.g. rgb to cmyk). The colours change on all the objects of the page but does not affect objects on other pages of the same document. Does applying an effect such as drop shadow or gradient alter the colour profiles of other objects?
Very puzzling. Is it a bug or am I doing something wrong?
I am on a Powermac G5 running Tiger. My colour settings are (throught Bridge) ProPhoto RGB and Coated Fogra 39 for CMYK.
Profile mismatches are set to preserve embedded profiles for both RGB and CMYK.

Thanks Peter for your quick response.
Your answer was spot on. Changing the transparency blend space to Document RGB has put it right.

Loader is invisible or behind other objects?

Hi all,
I have a loader that is either not visible or behind some
other display element that I have on stage, and am trying to figure
out how to get it visible. I can get this to work fine when I
isolate it, but when I implement this in my larger project, things
appear to load fine, but it does'nt ever show up on the stage. I'm
using addChildAt() to place it at what I think would be the top
layer on the stage. In the code below, the disaster_load_complete
is called, and I'm able to query the properties of the loaded
object (such as it's position, size, parent-- which is the Document
--, etc). But it's not visible on the screen! Can anyone help me to
troubleshoot this, and help is greatly appreciated!

i dont' see a problem with that code. use your complete
function to check if your loader's visible or alpha or x or y or
z-order has been changed. and make sure test.jpg is visible.

Fix Facebook like issue - comment window hides behind other objects

On my site htt://cocos-locos.com is a Facebook like widget. When a user clicks on the widget, the comment app hides behind a text box on the page. I tried moving it and no matter where this happens, BUT ONLY ON MY IPAD MINI. It opens in a pop-up window on the computer. Any ideas on how to fix this?

So, when a new file was analyzed and bpm with key values written into 'comment' field, Windows Explorer don't show it.
That field is not a default column. Do you have it checked in Details view? Right-click a column header in Details view or use Alt-V A (apparently) to add columns. Heh. Then there is a different UI depending on how you opened that
dialog. More... for the right-click method Choose columns... for the View, Add columns method. YMMV. Who knew?

Flex can create an AIR application.
But a swf file can't read from the local drive.

Mail not displaying images sent in emails

Not displaying images in emails

I'm using Apple Mail to view a Gmail account. I recently upgraded to Snow Leopard, but downgraded back down to Leopard when I experienced so many problems. After the downgrade, I have not been able to view images coded via html in emails. If I access the email account directly though Gmail, the images display just fine.
Does anyone know anything about this one?

Display image on jsp page

I have to display image on jsp page with some text output. This image is already saved at a location parallel to web-inf and is generated dynamically using a servlet. I have used img tag html to display the image. Other outputs are taking their values from database.
First problem is that image will be taking time to display in comparision of other outouts from database. I have to refresh the page to get imageon my page.
Second is that if I save image in a folder parallel to web-inf in my project then it will not be displaying the image.
Can I use any jsp functionality to display image with other outputs from database. I have used "*include*". but it shows only that image and other outputs.

Best way is to use a servlet for this.
<img src="path/to/imageservlet?id=someidentifier">

<img src="path/to/imageservlet/someidentifier">In the servlet's doGet() just write code which gets an InputStream of the image (either directly generated, or just read from the local disk file system, if necessary with help of ServletContext#getRealPath(), or even from the DB by ResultSet#getBinaryStream()) and writes it to the OutputStream of the response. That's basically all. Don't forget to buffer the streams properly to speedup performance and to save memory.
You can find here a basic example: [http://balusc.blogspot.com/2007/04/imageservlet.html].

Selecting an object that is behind another object

Is there a keyboard command for selecting objects that are behind other objects in the stacking order? or is the only way to select them from layers menu? i'm always selecting the object that is on top of what I want to select, and wonder if there is a keyboard command to "click down" to the object i'm aiming for
thanks!

Yes, LVOOP uses value based references, and when you split the wire to write the owner you created a data copy. The function you're after requires you do use a DVR for all class functions in which case you'll get reference based OOP, which is more familiar coming from text based OOP.
It just so happens that G# uses that approach, take a look at it.

Display byte array image or ole object in Section through dynamic code?

To Start I am a Complete Newbe to Crystal Reports. I have taken over a project originally written in VS2003 asp.net using SQL Server 2005 and older version of Crytal Reports. I have moved project to VS2010 and Cryatal Reports 10 still using SQL Server 2005. Have multiple reports (14 to be exact) that display data currently being pulled from database suing a dataset, each report has from 4 to 14 Sections. I have modified database table with two new fields. Field1 contains string data with full path to a scanned document (pdf or jpeg). Field2 holds a byte array of the actual image of the scanned document. I have tested the database and it does infact contain the byte array and can display the image via VB.net code. I can make the report display the scanned image using ole object.
Now my real question: I need to add a new Section and it should display either the byte array of the scanned image or the actual scanned image (pdf or jpeg) . How can I have it do either of these options via code dynamicly while application is running?

First; only CRVS2010 is supported on VS2010. You can download CRVS2010 from here;

To add the images, you have a number of options re. how to. You even have two SDKs that y ou can use (RAS and CR).
Perhaps the best place to start is with KB [1296803 - How to add an image to a report using the Crystal Reports .NET InProc RAS SDK|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333233393336333833303333%7D.do].

Displaying an image in large object type

hello
I am getting large object ( image) from a database.
like this way:
obj.read(buf, 0, obj.size());
I was not able to this image by OutputStream object
could you give me a hint ?
regards
Ahmet Temiz

orkun wrote:
InputStream is=rs.getBinaryStream(1); So you get an InputStream to read the image from.
byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];And you create a byte array which contains a bunch of zeros.
for (int length; (length = is.read(buffer)) != -1;) {
out.write(buffer, 0, length); # out is in OutputStream
}And then you ignore the InputStream where the image was, and copy all the zeroes from
the byte array to the output.
that did not display any image.
what may the problem be ?Do you need more explanation?

How to display "Image" object in the browser?

can anyone please tell me how can i display "Image" object in the browser?
I have an image object that i retrieved from AS400 BLOB object by using toolbox.jar (for as400 access for java including all necessary classes like jdbc driver, security etc.).
i want to display this object in the browser so i will be able to web-enable my BLOB objects stored on as400.thx...

In your HTML:
<img src="ImageServlet">
In ImageServlet:
Make calls to DB to get your image as byte array and store it in:
byte[] buffer = new byte[imageSize];
ServletOutputStream out = response.getOutputStream();
for(int i = 0; i < imageSize; i++)
out.write(buffer, i, 1);
out.close();

Can an ImageComponent object reference an image in other server locations?

Hello all -
I need display images stored in a folder on the server other than the folder where the web application is stored. However, pointing to any of those jpg images renders nothing as the application runs! To be able to render them, I must copy the images to the web directory of the application and reference them therein, just like in http://www.netbeans.org/kb/55/vwp-fileupload.html. So, this piece of code would work nicely:
String file = "/resources/1.jpg";
image1.setUrl(file);where of course file is a relative path inside the web app, and image1 of type ImageComponent is dropped straight from the pallette. But this would not:
String file = "c:/researcherData/images/1.jpg";
image1.setUrl(file);Is there a way to enable an imageComponent object to reference non-web-app files? Thank you.

Take a look at
http://developers.sun.com/jscreator/learning/tutorials
/2/file_upload.html#07.Thanks jetsons. That particular code sample (#7 in SJSC, #8 in Netbeans) shows only how to serialize a file to a different location on the server, not how to reference a file (not stored within the app forlder) to be rendered as a result of hyperlink click for example. Reading a little further in that page, it says:
Be careful when putting the uploaded files in the web application as anyone can access the files by URL, such as http://localhost:29080/MyWebApplication/faces/upload/images/myPicture.gif.
So, I am thinking that for added security, may be it is meant to be that I can't make an imageComponent reference a file outside of the wep app folder, but I am just guessing. In which case, I will simply have to store all such files within the web app folder before attempting to access them, unless someone has a better answer.

How to hide front panel objects behind other front panel objects

Hi,
I need tho change an existing project and to make it simple just want to hide some front panel objects behind others. But I can't find how to put the one I wnt to the front hiding all others. So now there are some in front that should be hidden.
Is there a button or menu item "Move to front / back" like in many other programs?
Thanks
Martin
Solved!
Go to Solution.

Hi Martin,
what about the link I provided in my previous post? What else do you need?
What about the chapter "fundamentals" in the LabVIEW help?
Going the way "Fundamentals -> Building the FrontPanel -> How-To -> Reordering Objects" seems rather logically to me…

Photoshop CC displays images 25% smaller than other apps?

Why is Photoshop CC displaying images 25% smaller than my other applications? If I open a 72 ppi square pixel aspect image in Photoshop, I have to zoom to 125% for it to be the same size on screen as in my browser or any other image viewer. Photoshop reads the correct pixel sizes, but displays it smaller.
I design and build websites and have been using Photoshop for over 15 years and haven't noticed this until CC. If I save the images and build out the site, or even just drag the image into a browser and then overlay that browser window above the Photoshop window to see both images side by side, I can clearly see a 25% difference in size.
If I zoom in Photoshop to 125%, then the sizes match. So, the problem is when designing a website, everything looks smaller in photoshop. Then when I build it out, everything is way too big.
My browsers are definitely at 100% zoom and I can open the image in any other image viewer at 100% and the affect is the same.
Is there a setting that can be adjusted in Photoshop to correct this?

I also have the same issue. I can reporoduce exactly what Roger2012Jr mentions above.
I have Photoshop CC, Windows 8.1, screen resolution 1920 x 1080. Files look really sharp in Photoshop, but when the file is exported (for web or not) the image is blurry and about 125% the size it was in Photoshop. Also, when I bring an image from the web, tried with a random image it still looks perfectly sharp in Photoshop, just about 80% actual size. That same image exported still looks perfect in the browser, same as it was originally.
So starting from scratch with an image, there's no way to guarantee the quality when exported and quality looks really blurry. I can't use the program with any sense of confidence.
Can someone from Adobe shed any light on this?
