Diff between images as .png

Hi Adobe Forum users,
I am trying to export the difference of two images as a png for use by another program.
One image is of a room with lights off, the second image is of the exact same room with lights on (everything lines up perfectly as they are CAD/rendered images). Is it possible to extract the difference (essentially just the effect of light) and place it onto a new layer with transparency?
I need to save this difference layer as a png and be able to overlay it on the image with lights off in the other program.
Thanks in advance,
Julian

Hi, thanks for your reply,
Yes I suspected as much.
The images are for a home automtion interface where multiple lights come on in a scene. Since there are multiple lights in the scene and each one can be individually switched I cant simply overlay one image. I need to overlay multiple images, one for each light circuit and these require alpha channels so other light images shine through.
It becomes difficult when multiple light effects overlap in the scene.
If your manual method could be useful in this situation please do explain further.
My Initial thought was that photoshop can detect the difference in two images and combined the images and exclude the difference. As far as I know it can then also isolate the difference but not with transparency. For my purposes I suppose it needs to be able to detect what colour pixels are in the 'lights off' image and what colours it needs to overlay to create the same effect as the 'lights on' image. . . but place these on a separate layer or as a colour overlay of some sort.
Maybe I am just expecting a little too much...
Thank you for any help!
Julian

Colours differ between image in PS CS4 and final saved image

Hi
Having an issue that is probably colour prifile ralated, but its got me stumped - i've tweeked everything to no avail!
(See system specs at bottom of post)
Ok, so IN photoshop itself, I open an image taken on my Nikon D300, which is set to Adobe RGB, the images are not RAW, just JPG.
In Windows itself the photos look ok, pretty faithful to the screen on the camera, however when i open one in PS, it is hugely over-saturated.
I have a nice photo of some red chillies on a green plate, looks good, lots of detail in the reds and greens, when viewed in windows preview, OR IN Internet explorer - and being a web designer - internet explorer is my baseline.
Once opened in PS, the red seems to be just pure RGB red... well not that extreme but close to.
If i soft proof, this helps a bit, but if i then save the image again, the resulting image is dull, and flat, (FAR duller than the soft proof) etc etc..
If someone can answer this id be very greatful
System:
Macbook with nvidia 9400 graphics (latest drivers) running Windows 7 (32 bit)
SCREEN CALIBRATED with a HUEY pro

I suggest you recalibrate again and make sure the resulting profile is saved in the correct place.
Also in case it's a Mac issue, you would be better off posting in the Mac forum.

Convert a Tiff Image to png and show

Hello;
I wanto to convert a Tif image to png and show this in my web page but i dont want to save the png iamge in my server.
Actualy i do that:
byte[] bytes = imagenData;
                ByteArraySeekableStream tiffStrm = new ByteArraySeekableStream(bytes);
                String[] CdcNms = ImageCodec.getDecoderNames(tiffStrm);
                ImageDecoder tifDecoder = ImageCodec.createImageDecoder(CdcNms[0], tiffStrm, new TIFFDecodeParam());
//                 Check the number of pages
                int IFDs = tifDecoder.getNumPages();
//                 Get the first page
                RenderedImage ren = tifDecoder.decodeAsRenderedImage(1);
                byte[] bytes2 = doSingleConversion(ren);AND
protected byte[] doSingleConversion(RenderedImage tifImage) throws Exception
          byte[] bytes = null;
          String out = "temp.png";
          try {
               //      Create the PNG file
               PNGEncodeParam pngParm = PNGEncodeParam.getDefaultEncodeParam(tifImage);
               JAI.create("filestore", tifImage, out, "PNG", pngParm);
               //Read the file into a byte array
               File f = new File(out);
               FileInputStream in = new FileInputStream(f);
               bytes = new byte[(int) f.length()];
               in.read(bytes);
               in.close();
               return bytes;
          catch(Exception e) {
               e.printStackTrace ();
               throw(e);
     }But this code save de image in the server; it�s posible do it without save.

Numbers the iWorks program? Not sure you can convert it to that or just a list of numbers. Never heard of anyone that would even want to convert an Image file, Photo, to any other format. Other then another image format like JPG, PNG or a PSD Photoshop file.

How can I make a server differ between two or more clients?

How can I make a server differ between two or more clients?
The clients can connect and talk to the server fine, but how can I make the server talk to one, two or all clients? i.e. what would be a good way to implement this?
Currently, the server listens for connections like this:
while (listening) {
try {
new ServerThread(this, serverSocket.accept()).start();
I guess one way would be to add the ServerThreads to a Hashtable with the client ID as key, and then get the ServerThread with the proper client ID, but this seems unnecessary complicated. Any ideas?

Complicated was perhaps the wrong word, I should have
written something like it doesn't "feel" right. Or is
this a common and good way to solve communication
between a server and multiple clients?Thats pretty much how I do it. I normally use an array or ArrayList of Sockets instead of HashTable, with [0] being the first player etc.... Then you can communicate with exactly who you want. If you want to send bytes to all of them, just send the same thing to each socket individually (or is there a better way to do this?).

In LSMW, what is diff between LSMW-BAPI and LSMW-IDOC

hello all
In LSMW, what is diff between LSMW-BAPI and LSMW-IDOC

Hi Swamy,
The differences between IDoc and BAPI are as follows:
IDOC
IDocs are text encoded documents with a rigid structure that are used to exchange data between R/3 and a foreign system.
Idocs are processed asynchronously and no information whatsoever is returned to the client.
The target system need not be always online. The IDOC would be created and would send the IDOC once the target system is available (tRFC concept). Hence supports guaranteed delivery.
With asynchronous links the sub-process on the client can be finished even if the communication line or the server is not available. In this case the message is stored in the database and the communication can be done later.
The disadvantage of asynchronous links is that the sub-process on the server cannot return information to the calling sub-process on the client. A special way for sending information back to the client is required. In addition, a special error handling mechanism is required to handle errors on the receiving side.
IDOCs may be more changeable from release to release.
IDOCs are poorly documented.
BAPI
BAPIs are a subset of the RFC-enabled function modules, especially designed as Application Programming Interface (API) to the SAP business object, or in other words: are function modules officially released by SAP to be called from external programs.
BAPIs are called synchronously and (usually) return information.
For BAPIs the client code needs to do the appropriate error handling.
Problems with synchronous links occur if the communication line or the server is temporarily not available. If this happens, the sub-process on the client cannot be finished (otherwise there would be data inconsistencies).
Synchronous links have the advantage that the sub-process on the server can return values to the sub-process on the client that has started the link.
BAPIs are not totally immune to upgrades.
BAPIs are reasonably well documented.
Reward points if useful.
Best Regards,
Sekhar

Dragging images to the desktop copies image as .png instead of .jpg

I have nearly identical computers at home and work. Both are XP Pro, with Firefox 3.6.
When I drag an image out of a web page, onto the desktop, my home computer saves/names the image as a .jpg, but my work computer saves/names the image as .png.
I want my work computer to save/name the image as .jpg. How do I change it?

Do you get a real PNG file or a JPG file that has a .png file extension?

Diff between programme BBP_GET_STATUS_2 & CLEAN_REQREQ_UP in SRM7.0

Hi Experts ,
We have ECC6.04 with SRM 7.0 with Classic Scenarion
I am confused over exactly what BBP_GET_STATUS_2 do in SRM ?
I believe CLEAN_REQREQ_UP update the SC with follow on document i..e Classic PO....
and BBP_GET_STATUS_2 update the entries in BBP_DOCUMENT_TAB..but not getting exactly what is does..since if we change qty in Classic Po ..it automatically updates automatically in SC follow on document...if we Craete GR in ECC it updates automatically in SC follow on document...
Can anyone please suggest me exactly what BBP_GET_STATUS_2 do in SRM ( what is exact diff between both )?
Thanks
NAP

Hello,
Report : BBP_GET_STATUS_2
Function : This reports updates the requirement coverage requests (Shopping carts) to ensure that information on the status of backedn purchase requisitions, purchase orders, and reservations is up-to-date.
You should schedule this report to run daily in the SRM server system.
Report : CLEAN_REQREQ_UP
Function : Interval for update check.
Updating of documents (purchase requisitions, purchase orders, reservations) is executed asynchronously in the backend system. You can only process the requirement coverage request in the SRM server system further after the update has been carried out. At the interval defined by you in Customizing, the system checks whether the documents have been updated and thus if you can further process the requirement coverage request.You should schedule this report periodically.
Hope this helps.
Best Regards,
Rahul

Saving images to PNG

Hi,
I'm trying to save my images to PNG so that I can upload them on the web. I need the images to be a specific size - which I stipulate via the artboard size.
However when I try to save my images (via File, Save for Web and Devices) the image never saves to the size/outline of the artboard.
Does anyone know why this happens and how I can get my images to save to the pixel size that I need?
I'm using Windows 7 and have Illustrator CS5
Thanks

When you create your original document do you set the profile to Web and check that the ppi/dpi settings are the same as the output you need for your webpage?

Spaces in between images ; textbox help

in my dreamweaver HTML page, after i insert say like, 5 images, they clump all together, and i'm unable to separate them (like how i'd be able to do them in microsoft powerpoint)
is there anyway that will enable me to freely shift around these images, so that they are not always joined together?
another questions, how can i insert a space for me to type what i want, without the annoying form box, where you fill in stuff in surveys. it'd be like inserting a text box in microsoft ppt, just allocating a space for you to put in your words
hope you guys know what i mean!
EDIT: i've realised that i can put in the H and V space. but how would i say, put in a paypal "buy now" button HTML code, under that space? is the space usable?

Building web pages in Dreamweaver is nothing like working with PowerPoint. This isn't a click and drag application. If you switch to Code View, you can insert non-breaking spaces ( ) between images like so:
<img src="some-image.jpg"> insert space, insert space, <img src="some-other-image.jpg">
To add captions to images, you will need a working knowlege of CSS and HTML code.

Diff between Thin client and Rich client

Hi Everyone,
Can someone give me a clear picture of the what is the diff between Thin client and Rich client.
Thanks,
Krishna

Hi,
thick client (rich client) has/stores all the data inside itself
so it can do application processing without the server with data
thin client uses resources from host computer (from server)
and wihtout that you are not able to work with that kind of client
does that answer your question ?

Diff between Seeburger Adapter and File Adapter

Hi All,
My company needs to interact with some banks and the banks are particular that they want SFTP, which is not supported by File Adapter, so we have decided to go with Seeburger adapter.
Now what are the differences between File adapter and seeburger adapter?
I believe that Seeburger adapter does not support File Content Conversion, Archiving etc.
Could you all pls put some light on the diff between file adapter and seeburger adapter when it comes to dealing with files?
Xier

Hi
You are aware with working of File Adapter.
The most direct way of using the Seeburger adaptors is to configure the BIC as a module. There is a software component from seeburger called bicmapper which will allow you to
1. Define or import the inbound message metadefinition in various formats ( edifact, xml,...)
2. Using a mapping create an xml variant as the output metadefinition or edifact in the other direction.
3. Create a one to one mapping between input en output.
4. Export the metadata in xsd or sda format for import in XI
5. Generate an SDA which can be deployed in XI and used as a module.
