Image loading bad performance!!!!

I have a background image on a Jpanel and i have added some buttons on the JPanel. The problem is when I start my application, the buttons are visible about 5 secondes before my background image. So, how can I improve my dowloading performance of my background image...
thanks all.....
Yannick

How do you add the background image? Do you have a custom component? If you do, then use the ImageObserver interface.

My firefox is loading Bad quality images, but actully the images are perfectly alright

My firefox is loading Bad quality images, but actully the images are perfectly alright

In my experience, print quality settings such as dpi/ppi are hidden in your printer driver settings and not directly available through Firefox's UI. In the print dialog, if you click the Properties button, you hopefully will gain access to this setting. Obviously native web resolution (96ppi) can give disappointing results, so hopefully you can find a place to increase it.

Problems with image loader 'swissarmy.js' in 7.0.1

My Javascript image loader 'swissarmy.js' at www.sustainableaggregates.com loads images right justified in 7.0.1, in older versions of Firefox or all other current browsers it's OK.
Is this a bug in Firefox 7.0.1 rendering engine or is it down to a bad piece of Javascript. Swissarmy.js is used a lot in many websites.
Will a future imminent FF upgrade cure this or do I need to source a new image loader script?

Issue with Image Loader in 14.0

Hi All,
In our application, we have a custom function module in ECC, which is passing the URL of an image uploaded on the content management server(KPRO). Custom FM calls 'SDOK_PHIO_GET_URL_FOR_GET' to get the URL of the image.
When we execute the FM in ECC, we get the URL as:
http://gbswidkprodb01.global.rexam.net:81/ContentServer/ContentServer.dll?get&pVersion=0046&contRep=YA&docId=001F296E9EB61ED3B6F490000438C20C&compId=TJ12A.jpg&accessMode=r&authId=CN%3DBC3,OU%3DI0520020335,OU%3DSAPWebAS,O%3DSAPTrustCommunity,C%3DDE&expirat
when I use this URL in the browser the image gets loaded in browser.
When I capture the output of JCO call in write file URL returned from FM is:
http://<server>:81/ContentServer/ContentServer.dll?get&pVersion=0046&contRep=YA&docId=001F296E9EB61ED3B6F490000438C20C&compId=TJ12A.jpg&accessMode=r&authId=CN%3DBC3,OU%3DI0520020335,OU%3DSAPWebAS,O%3DSAPTrustCommunity,C%3DDE&expiration=20140617181313&secKey=MIIBUgYJKoZIhvcNAQcCoIIBQzCCAT8CAQExCzAJBgUrDgMCGgUAMAsGCSqGSIb3DQEHATGCAR4wggEaAgEBMG8wZDELMAkGA1UEBhMCREUxHDAaBgNVBAoTE1NBUCBUcnVzdCBDb21tdW5pdHkxEzARBgNVBAsTClNBUCBXZWIgQVMxFDASBgNVBAsTC0kwNTIwMDIwMzM1MQwwCgYDVQQDEwNCQzMCByASCCcTUiEwCQYFKw4DAhoFAKBdMBgGCSqGSIb3DQEJAzELBgkqhkiG9w0BBwEwHAYJKoZIhvcNAQkFMQ8XDTE0MDYxNzE2MTMxM1owIwYJKoZIhvcNAQkEMRYEFM%2FKd4MzWL0y1KfF58AHNg9PYqOlMAkGByqGSM44BAMELzAtAhUAtqASnXbD3E2ZM8EhG%2FLxgJhKCs0CFH0qFlBxzWlzS8kjeFw3kad63SHW
when I use this URL in the browser I get 'HTTP 400' error.
Using either of the two URL's in the image loader I get the error:
[WARN] [ImageLoader_0]ImageLoader_0 Status: 400 - (bad request)
We are currently on SAP MII 14.0 SP05(patch 3).
Thanks in advance for your help.

Sam,
I tried logging in to ECC with the same user as the one that is making the Jco connection and it is giving the same URL which i was getting earlier when i was executing the FM with my user id. I am testing the FM through SE37.
There is no logic in the custom BAPI to replace the <server> keyword. Based on the image name, it gives the URL of where the image is stored on the KPRO server.
Could not find URL Decode function in the MII link editor, i believe it is the decode function which you are referring to. Even that is not working. If it is something other than this, do let me know.
PS: This works fine in the 11.5 system from which we have upgraded to 14.0.

No Action Until Image Loads, Please

For some reason the squares of color that are supposed to load behind the image that acts as a mask load first, momentarily showing while the image loads, which looks bad. Hre is the code:

I have experimented with adding the square child elsewhere (such as in the code where it is created twice), but that proves even more disastrous. Please advise.

How to solve bad performance in vi server

I'm useing vi server in a recursively programming structure in labview 7.1.
I have very bad performance result so i made a test comparing the speed of che various vi server call and the native.
my tests are:
normal calling.
vi server calling by reference node
vi server calling by invoke node
for each vi server calling type i tried:
unique reference calling
different reference calling
different reference, preloaded, calling
the only 1 case i found a loosing of performace acceptable 24% respect the normal calling: vi server calling by reference node with unique reference.
unfortunately this kind of calling is able to catch come kind of recunsion an forbidden it and this calling wait all the time the end of the execution of the vi called.
All the oter kinds of caling have very bad performance: from 90% to 99,9% LESS then the normal calling (10 to 1000 times more in execution time).
In addition there is a prblem in invoke colling: if you execute a invoke node with wait until done true, the mouse pointer fliks with the busy icone. that heppens in all the possible configuration.
I would like ti know if someuone as some solution to this performance problem and if Labview 8.0 fixs this problems.
Best regarda.
ing. Luca Benvegnù

Hi Luca,
I've made some researches for you and, what can I say is that there is a certain number of requests about "vi server performances". There are some things that are in general suggested in this situation:
1) Be "minimalist" about the use of images, graph,... And avoid Large data structures: wiring large structures into/out-of sub-VI's can take time: pass the smallest amount of data.
2) Avoid repeated calls. Calling the sub-VI's frequently, in a loop for example, create a call over-head that could be an issue. For the same reason put the "wait until" function with a specification of time in order to run loops only as often as strictly required.
However, about your question of fixing the problem with LabVIEW 8.0, I suggest you to download the Evaluation Version of LabVIEW 8.2 and try by yourself if performances are better.
I hope I've been of some help.

Question about image loading problem

Dear Java Gurus,
I am writing a simple Java Applet application. Basically what it does is every 3 seconds, it tries to get an image from a server and display it (also based on the browser�s client size to do some resize of the image to fit the width of the browser�s client area). But frequently I got this kind of exceptions:
----------------------------- Exception 1 --------------------------------------
Uncaught error fetching image:
java.lang.ArrayIndexOutOfBoundsException
at java.lang.System.arraycopy(Native Method)
at sun.awt.image.PNGFilterInputStream.read(Unknown Source)

at sun.awt.image.InputStreamImageSource.doFetch(Unknown Source)
at sun.awt.image.ImageFetcher.fetchloop(Unknown Source)
at sun.awt.image.ImageFetcher.run(Unknown Source)
----------------------------- Exception 2 ------------------------------------------
sun.awt.image.PNGImageDecoder$PNGException: crc corruption

at sun.awt.image.InputStreamImageSource.doFetch(Unknown Source)
at sun.awt.image.ImageFetcher.fetchloop(Unknown Source)
at sun.awt.image.ImageFetcher.run(Unknown Source)
Which will cause the image goes to blank in the browser and also degreed down the performance, and I do not know where they are coming from. I tried to put try-catch blocks at possible method calls, but still it does not catch these kind exceptions.

Master column tree - bad performance

Hello,
I have a table with master column that uses recursive node without Load Children event. the whole table loads at startup. I Have very bad performance : every click on the little triangle takes about 6-7 seconds, and there is even no round-trip to server because all data is already at the client!
I need to show list of products by there family (50 families, each has 10 products). How can i imporve my performance (maybe server configuration or my code or another method)
I work with ep 7 sp12.
Thanks
Roni.

Hi Roni,
Yes, you have to manipulate the add element on before loading the tree. Best Practice is to use onLoadChildren event. Loading the tree at once will always have performance issues.
Refer to these tutorial for creating tree using onLoadChildren event.

Bad performance video in on vivo card?

This opinion posted as a reply in other thread. But because I think It is proper to be an issue for discussion
I am posting in a new thread. Let alone the difficulty in configuration, the vivo of this card seems to have a poor performance.
I too have a GeForce 4 Ti4200-VTD8X-8894 AGP 8X 128MB.
Vidio in working in a machine, but not in other machine.
I also have a ati tv wonder pci, The configurations of the capture driver on both machine appeares to be the same but behave differently, which I don't know why at all.
What I've found so far :
1. For tv(videoin) decoding: dscaler1.7(alpha) works on both machine(but on bad one freezes often)
2. On the bad machine using any capture driver causes pending (ie. in windows movie maker or virtual dub), drivers(1.27 or 1.22) have the same behavior.
3. While comparing the performance of tv decoding, I found a big issue. Tvwonder was very vivid on screen and the cpu usage was only 8% while vivo was very rough(skipping, ...) and the cpu load was over 60%.
So the conclusion?
The tv in of this card is only for the poor. If you can bear the poor performanc, you can spend lots of time to enable it and get bad performance. I'd rather buy a h/w decoding tv card for $30 or more. With amd xp 2.1G, and Tvwonder and window media encoder, I was able to broadcast to 1.5g bandwidth of video quality while watching the movie on Window media player on the same machine. The cpu usage was around 80%. But with this card, I cannot dream of it at all.
It is said that this card has bt848 decoder(So can be played using dscaler1.7). Then how come this card be so slow on decoding? Bad configuration? Possibly. If anyone who could watch tv(through vcr) fast enough with low cpu usage, please let me know the secret.

I started again from scratch (3:th time), installed win98 on a clean HD and installed the vga driver from the cd in the box. Then I installed Winproducer from the cd, but the capture program I have to browse on the cd to install. The capture seems to work now, but I can not save my recording from my camcorder, some error message is poping up and the same message is when I tried to play the saved file (there is a saved file anyway).
I have problem whith my network card also byt only in win98, complaining about ndis.vxd (can´t load ndis.vxd).
So I have to install W2000 to get internet.
When I installed the Winproducer on W2000 the computer rebooted all the time, is Winproducer not compatible whith W2000 ??
I have not downloded anything yet (se abow).
And where can I find this 28.32 or 29.42 ?
WDM, I have installed this time.
Thanks NE

Very bad performance of NWBC in IE11

Hello colleagues!
I've faced with a bad performance of NWBC in IE11 after update to NW7.02 SP16 GRC10 SP18. According to the pam IE 11 is supported.
When I log in and try to create an access request I get a picture with slow circle
(the message at the bottom of the window indicates that I've switched off all security settings and plug-ins)
After 1-1,5 minute I get a normal screen
If I try select an entry from any drop list or perform any other actions the window hangs with information (Not responding)
Has anyone experienced the same problem in GRC or similar products?
My search results for this issue were not successful.
I suspect that the problem is in NWBC, because webgui works fine, and hope that someone can provide with the corrections.
I've tried to use httpwatch, but it hasn't shown any useful information. I only identified that big time consumption happens when load one page (see below)
Could any one advice how to resolve the issue ?

Previously I had 7.33.3.68.0.
So, I don't know what else can do... If I roll back to Explorer 9, the problem disappears, however another user with IE9 experiences the same problem. FF works fine.
Could you give me please another idea to resolve the data?

CMP 6.1 Entity bad performance.

I'am using entity 1.1 EJB on WL 6.1 and facing very bad performances:
around 150ms for an insert (i have 20 columns).
When accessing an order interface to read 2 fields in a session bean method: around
90 ms.
I'am very disapointed and confused. What should I look up for
to increase the performance ? Any important tuning or parameters ? Should I use EJB
2.0 to have significant perf ?
Thanks for any advice because we are thinking to switch all the application on stored
procedures. A solution without Entity and fewer stateless session beans.
My config:
WL: 6.1 on Sun sparc
SGBD: Sybase
Entity: WebLogic 6.0.0 EJB 1.1 RDBMS (weblogic-rdbms11-persistence-600.dtd)
Thanks

Historically its hard to get good performance & scalability out of sybase
without using stored procs. Using dynamic sql on sybase just doesnt do as
well as procs. Oracle on the other hand can get very close to stored proc
speed out of well written dynamic sql.
As far as weblogic goes, my experience is the focus of their testing for db
related stuff is Oracle, then DB2, then MSSQLServer. Sybase is usually last
on the list.
As far as the 6.1 cmp, haven't used it much, but because of these other
things I would be cautious about using it with Sybase.

hey sorry for posting it in this forum.
but do u have sample code for making it work.. since i am able to do it on PDF format(image from Database and another stored in the webserver) using
byte image[] =(byte[]) outData.get("image");
                    ByteArrayInputStream img = new ByteArrayInputStream(image);
                    hmimg.put("P_PARAMV3", img);
print = JasperFillManager.fillReport(reportFileName, hmimg, jrxmlds);
bdata= JasperExportManager.exportReportToPdf(print);

Bad performance when open a bi publisher report in excel

We use bi publisher(xml publisher) to create a customized report. For a small report, user like it very much. But for a bigger report, users complain about the performance when they open the file.
I know it is not a native excel file, that may cause the bad performance. So I ask my user to save it to a new file as a native excel format. The new file still worse than a normal excel file when we open it.
I did a test. We try to save a bi publish report to excel format, the size shrink to 4Mb. But if we "copy all" and "Paste Special" value only to a new excel file, the size is only 1Mb.
Do I have any way to improve that, users are complaining everyday. Thanks!
I did a test today.
I create a test report
Test 1: Original file from BIP in EBS is 10Mb. We save it in my local disk, when we open the file, it takes 43 sec.
Test 2: We save the file in native excel format, the file size is 2.28Mb, it takes 7 sec. to open.
Test 3: We copy all cell and "PasteSpecial" to a new excel file with value only. The file size is 1.66Mb, it takes only 1 sec to open.

EBS or Standalone BIP?
If EBS see this thread for suggestions on performance tuning and hints and tips:
EBS BIP Performance Tuning - Definitive Guide?
Note also that I did end up rewriting my report as PL/SQL producing a csv file and have done with several large reports in BIP on EBS.

How can i control what images load on my project to save preload time and avoid loading all images, elements, divs not yet visible?

Sup buddies,
How can I control what images load on my project to save preload time and avoid loading all images, elements, divs not yet visible?
As the project grows in size the load time increases. How does one control not loading all images ,divs,elements etc. until they're
needed on the timeline? For example some sections are off and only become visible when recalled. My projects slowly grow in size so loading
all images , is counter productive . My other option would be to create separate htmls but that breaks the seamless user experience .

hello, kiwi

yes.
maybe,...
1. you might think of making DVD backups first prior to importing the photos into Aperture. "Store Files: In their current location" once in Aperture make low rez Previews, and export finished Project.
or,
2. bring in the photographs to hard drive first prior to importing the photos into Aperture. "Store Files: In their current location" once in Aperture make low rez Previews, and export finished Project.
the low rez Previews will stay in Aperture but the high quality Versions will be exported onto DVDs and gone from the hard drive (if you delete the originals).
another way would be to export small about 50-70 pixel wide high quality jpegs to a folder on your Desktop and import & keep these in Aperture Library as a reference. make metadata to show where the original Project DVDs are stored and DVD filing system used.

Any Way I Can Make My Page's Images Load One At a Time?

Hi folks,
I have a page with a stack of large images. It takes several seconds for them all to load, but I was wondering if there's any way I could dictate the order in which all of these images load? This way, the top image would load first, then the the next one down, and so on, leaving little perceivable page load time for visitors.
It seems like this would be a common necessity for a web page, does anyone know an easy (because I know very little about this) way to do this?
Thanks!

One major problem, is that you have scaled the images in DW, and not in a graphics program. I have your page open in the background and it's been a while loading and it's still not finished :-)
eg: the following images has properties of:
http://www.selfeffacingtheories.com/web-content/pictures/picpics/holes.jpg
933px × 699px but you have scaled it to: 615px × 458px
Trying to put your page through the Web Optimiser - doesn't show a very good result - it couldn't be tested because it exceed the size requirement.
http://www.websiteoptimization.com/services/analyze/
The size of this web page (4264698 bytes) has exceeded the maximum size of 3000000 bytes.
This is just way too big a file size and seriously needs to be optimised. The only way to do this is to scale down the images in either Photoshop or Fireworks.
Why not use a lightbox effect, where you show a much smaller size of the image and then when someone clicks on it they see a much larger version of the image:
My small demo here: (using the Dreamweaver Lightbox Extension)

Image loading bad performance!!!!
