Client side image resize

Hi,
is client side image resizeit possible with flash? If so,
then from which version?
Cheers,
Sven

you have to load the image into flash before flash could do
anything. then if you want flash to resize the image that would
only require flash 4 and all that would be done on the client-side.
however, if you want to upload the file without using
server-side code you'll need flash 8.

Client side image resizing

Hi all,
Is flash capable to resize images in clients computer and
then upload them, keeping in mind the sandbox security of flash?

The only way I see is to use the BitmapData class if you have
Flash 8 (it's Flash 8 only). It could get the pixel values of the
scaled image and transfer those to the server, where the picture
gets re-created by the values. I guess this will result in a larger
amount of data than transfering the image itself.
Maybe there's another way with 3rd party software, that
allows Flash to save the scaled image. It's not possible with Flash
alone, but probably with some extra software.

Possible to use RMI to upload client side image files?

Is it possible to use RMI to upload client side image files? My intent is to allow remote clients to upload a number of small image files (jpg & gif) to a central server DBMS, by modifying a "Customer" object (eg adding a new Image object to a vector of Images?) Is this possible? Any suggestions greatly appreciated :))

Is it possible to use RMI to upload client side image
files? One possibility is to implement a serializable image object that you can upload to the server as any other object. When your server receives this serialized image object, just generate a new gif/jpg from it.
But if your client-program is an applet, the situation is different: how can applet read image-file from users harddrive?

Creating Client-side Image Map in Web Dynpro

Hi,
How can I create a client-side Image Map in Web Dynpro application?
My application consists of a screen-size image in which several areas will have to link to URLs and actions. I have browsed through the "Web Dynpro UI Element Reference Guide," but could not find anything appropriate.
Can someone give me an advice? Thanks.
Teecheu

It doesn't, there is no corresponding UI control for this.
There is only onAction event on BusinessGraphics (have not working with them since SP5, eventing did not work at that time) and onObjectAction in GeoMap (never see it in action, probably an option for you if your map is geographic map

Creat a client-side image map in JSC

Has anyone sucessfully created and implemented a client-side image map in JSC? I can get it to compile but it falls over on execution with a 500 error:

How to implement a client side map with ObjectImage control?

We need to implement a client side map with an ADF Faces ObjectImage control. In the code below, the JSF Faces GraphicImage contol does support a client side image map using the usemap property. However, it appears that the ADF Faces ObjectImage control does not support a client side map. Is there someway of implementing this functionality in an ObjectImage control?
<h:graphicImage url="/images/map-usa.gif"
usemap="#m_mapusa"
binding="#{backing_map.graphicImage2}"
id="graphicImage2"
style="border-style:none;"/>
<af:objectImage source="/images/map-usa.gif"
binding="#{backing_map.objectImage2}"
id="objectImage2" />
We could use the Graphic Image control except we have a problem by mixing a JSF GraphicImage control in the same table with a variety of ADF Faces controls in that when a user clicks on the GraphicImage, then the browser windows scrolls down to center the GraphicImage control. A user then needs to scroll back up to see the rest of the page. If an ObjectImage control is used with an onClick action, then the page does not scroll, which is what we want. So if we can figure out how to add a client side map to an ObjectImage control we would get the desired results.
An alternative might be to use a server side map with the ObjectImage control. But our question here is how to implement the existing client side image map in a backing bean. As the following map code shows, not all image map areas are rectangles - some are polygons.
<area id="_state_05" href="#"
shape="rect"
coords="681,38,702,50"
target="_self" value="VT" alt="Vermont"
onclick="javascript:getDtl(this);"/>
<area id="_state_06" href="#"
shape="poly"
coords="221,442,209,436,209,418,191,403,155,382,116,367,101,370,98,364,

Problem in creating client side PDF with image using flex and AlivePD

I need a favor I am creating client side PDF with image using flex and AlivePDF for a web based application. Images have been generated on that pdf but it is creating problem for large size images as half of the image disappeared from that pdf.I am taking the image inside a canvas . How do i control my images so that they come fit on that pdf file for any image size that i take.
Thanks in advance
Atishay

I am having a similar and more serious problem. It takes a
long time to execute, but even attaching a small image balloons the
pdf to 6MB plus. After a few images it gets up to 20MB. These are
100k jpeg files being attached. The resulting PDF is too large to
email or process effectively. Does anyone know how to reduce
size/processing?

How to load images from client side when the swf is hosted on a server without uplaoding it to server?

I'm trying to build a online image resize tool.
problem i face are:
1. I build a button that allow user to browse the file. Once
file is selected, it doesnt show full path.
2. lets say if it shows fullpath, but i try to load it into a
movieclip, and it doesnt work because the swf file is located at
the server and not the client's place.
3. as far as i know, flash can only load images which is
located in the same server or internet.
4. if i use php, asp, cgi.. it can only allow me to 1st
upload the image then resize later, but this is not wat i want.
5. I need to 1st resize then upload later, because if i have
100 and more photos taken from digicam, it's going to be very slow
and heavy.
What i have tested:
1. upload "image3.jpg" into the same directory as the
"viewer.swf", and it works.
2. do not upload the swf to the server, but run locally from
the user's computer and open "image3.jpg" and it works.
3. upload the swf to the server and open "image3.jpg" from
the user's computer and IT DOESN"T WORK!
please help me out.
Thanks~!

Crystal report printing in client side

Hi ...
I have using asp.net web app with crystal report version 10.5.3700.0
I have uploaded the project and database in the below link. Check out.
http://www.2shared.com/file/vHTSGl13/ASPnet_Webapp_using_CR_Rpt_Pri.html
http://i52.tinypic.com/2rdds7d.jpg
I have few requirement in the crytsal report asp,net page:-
1) If user click Print button of crystal report viewer toolbar then it goes to PDf then its show me all of my pages instead of showing me the current page on which i click print.
2) I want to use client side print..if user click on a my print button then i need to show print dailogue like image above in that if user click print then i need to print that current page.. let us consider im viewing I3 Invoice number using Crysatl report viewer Navagition then it show me as 3/7 in toolbar if user click on my print button then i need to print the page 3 only.. coz user clicked print on Page3.
3)My asp.net web app is in Hosting server if user click my print button then i need to show client print dailogue and it will show my cleint connected printer. Here crytsal report toolbar and other things should be hide. It should be like what we have designed in crystal report that alone should be get printed.
4) One more thing i want is if user gives I4 invoice no. in my textbox1 then click view report button then it will show that Invoice Report now its shows two pages, here if user click print then i need to print two pages coz it has two pages...
Please do a code using my webapp which is above and waiitng for your codes..
Thank you
Note: please do a code so that i can know, i already visited some of the website like http://aspalliance.com/ i didt undertstand how to do so im posting here to get a code.

*i tried this also but it show me the same only hosting server printer not a client side printer*
if (System.Drawing.Printing.PrinterSettings.InstalledPrinters.Count > 0)
            foreach (String myPrinter in System.Drawing.Printing.PrinterSettings.InstalledPrinters)

How to 'client-side include for secondary menu on page'

Hi there.
The following page refers:
test page for early
draft
The linked page is in fact a DW CS3 tmp preview file, for
that reason the CSS has been pulled into the html file by DW, it
won't look that way in the eventual page file.
After lengthy battles with the Spry Horizontal menu, I
eventually resorted to Pop Menu Magic 2 (PPM2) to generate menus.
I'm very happy with the product (I'm not looking for PPM2 support,
but rather support pertaining to CSS-driven menu's in general
relating to caching). I started out with a single main navigation
menu, which was very comprehensive - but also very big (ito file
size). I was hoping to cache a part of the menu on the client-side
to reduce download times once the site visitor has downloaded the
first page in the site (where he enters the site is not
applicable). But that proved impossible (I think...).
I then followed some advice to break up my main navigation
menu, keep only the more important stuff in there and rather
distribute the lower levels of the main menu into their own
dedicated menus. From there the page linked above.
The main menu at the top is fine, no problem there. On the
left below the masthead I've created two menus, one above the other
(it displays as a single menu but the first menu ends above the
"Other tour lists" item). The first of these two menus contains the
bulk of the heavy navigation elements (±160kb of the total
page file size of 220kb). The div info that applies to this menu =
<div id="p7PMM_2" class="p7PMMv06">. I'd love to cache this
menu, either in full or the bulk thereof, on the client-side. That
is implement a client-side include. When a visitor first enters our
site the include file with the 160kb (secondary) menu gets
downloaded together with CSS stylesheets, etc. When the visitor
links through to a following page in our site, his machine
(client-side) dishes up the menu to that next page without having
to download it from our hosting server a second time.
Is this possible and how? Any and all suggestions will be
appreciated!
Our clients are mostly wealthy and thus probably (virtually)
all have high-speed broadband connections. I seriously doubt that
any of them are running dial-up connections. Thus this issue is not
going to sink our site. But I'd love to cut page file size if
possible.
Furthermore, I'm not too worried about the small portion of
visitors that may have their javascript disabled in their browsers.
The main navigation menu at the top of the page will still allow
them to navigate the site. Much the same goes for SEO.
I've tried one or two CSI javascripts and succeeded in
actually getting the relevant tags and contents inserted in the
html document, but the javascript would then 'break'. That is all
the coding and menu contents would be there, but the javascript
won't function (menu's won't pop / fly-out). I'm a little clueless
when it comes to Javascript, and many other things :-), but I
suspect that the Javascript in the include file does not get
called. If the Javascript is kept in the html file, the menu
content (elements) in the include file arrives in the html file
after the relevant script has been called and doesn't get
rendered??
Once again any help / suggestions will be appreciated!

> But that proved impossible (I
> think...).
Even without doing anything on your part, the images, the
CSS, and the
javascript is already cached client-side. You cannot cache
any of the
structural code client-side.

Can we access popularity trends using client side script?

Hi,
I have a requirement to show the hit count for my image library's item(s). When ever I am opening an image from the image library, I just wanted to show the hit counts. For this I have created a Number column and updating this column by using CSOM
when ever hit happens to that particular item.
The problem arises here, for visitors ( who has read only permission to the site) I am not able to update the column due to permission issue. Since we all know that we can't elevate the privilege from client side script. And also our design says that we
can't give the contribute permission to all the users at the library level. How can we update the count at item level even when the visitors are opening an item from the image library?
Please help me...
Thanks in advance

Client-side caching of Javascript (for Google Web Toolkit *.cache.* files

Hi all,
I'm trying out the use of Google Web Toolkit (GWT) for AJAX code development, leveraging RPC calling back-end Web Services for a document browser prototype. When the JavaScript code is generated by GWT, it has the ability to automatically distinguish between cacheable and non-cacheable content via file extensions (.cache. and .nocache.).
Now when running in a Tomcat environment with appropriate caching settings; the application runs extremely fast even on really poor latency sites (>500ms round trip); however on a NetWeaver stack, I can't find any information on how to set an attribute on .cache. files to set an expiry of 1 year.
Anyone know how to do this on a NetWeaver J2EE stack?
Thanks,
Matt
PS. For reference, GWT is a very cool open source project worth watching in the Enterprise space for targeted high-usability, high performance apps. Just the image bundles concept themselves are an awesome approach to minimizing impact of small images on performance.

Hi again,
I thought I should post the solution I came up with in case people search on GWT in the future. In terms of caching, the Portal does a good job of making nearly everything that GWT produces to be cached at the client; and for the life of me, I couldn't get nocache files not cached at the client side.
So thanks to my friendly local SAP experts in the portal space; I discovered there's not much you can do to get this working except try use standard browser tags like the following to prevent caching on the browser:
Note - Can't seem to save this post in SDN with Meta tags that I'm trying to display so check out http://www.willmaster.com/library/tutorials/preventing_content_cache.php for more info...
Unfortunately, the way that GWT creates the nocache files, it is not possible to modify the .js files to do this so I needed an alternative approach.
Then I thought, well, the html file that includes the JS file is cached, but it's not very big, so how about I just write a script to modify the html file when I deploy to production to point to the nocache file with a date suffix.
Let me explain in more detail:
1. The original html file that includes the nocache.js file gets modified to point to nocache.<date>.js.
2. The original nocache.js file gets changed to nocache.<date>.js
3. Now produce an external bat file to do this automatically for you before deployment which DevStudio can call as part of an Ant script or similar.
That's it. So when you are developing, you can manually delete your cache, but just before you go to production, you do this conversion, and you will never have an issue with clients having the wrong version of javascript files.
Note - GWT takes care of caching of most of the files by using a GUID equivalenet each time you compile, so it's just a couple of files that really need to not be cached.
Anyway, I'm not explaining this solution very well, but drop us a line if you need to understand this approach further.
And lastly, my feedback about GWT - It Rocks! Everyone loves the result, it's easy to build and maintain, it offers a great user experience, and it's fast. Not a replacement for transactional apps; but for the occasional user - go for it.

ACE30 - PING to VIP and Client side SVI not working

Hi Guys,
Having setup the ACE30 based on the configuration guides, I've been able to get basic load balancing working, probes, stickness etc. However in testing connectivty, I've noticed that from the real server on the backend I cannot seem to PING:
1. The VIP for the web service that the server is a part of
2. The Client side SVI
I'd like this to work to ensure full connectivity.
I've applied ACLs to the Client side SVI (on the ACE) to allow this in both directions, and also removed any ACLs attached to the client side SVI on the MSFC where the subnet is actually homed. However I just cannot seem to PING the Client side SVI on the ACE, or the VIP. Trying to understand if this is normal behavior.
Have inserted my config below for completeness.

To ping your VIP of the webserver, you should apple the service-policy input command on VLAN 186 too. Currently the VIP only listens on VLAN 11. For the SVI i think that was forbidden by security reason, but i cant remember anymore. Maybe you just need to put the management policy on the interface VLAN 186. If it dont work, then my first guess was right

Image-resize servlet

Hi,
I�ve been working on an image-resizing servlet on and off for quite some time now, and I just cant seem to get it to load the image correctly.
I guess its very simple once you figure it out. The following is the interesting part:
Image image = Toolkit.getDefaultToolkit().getImage("../pictures/pic" + pictureId + ".jpg");
MediaTracker tracker = new MediaTracker( new JFrame() );
tracker.addImage(image, 1);
// Load image
try {
tracker.waitForAll();
} catch (InterruptedException e) {}
// Scale image
image = image.getScaledInstance(width, height, Image.SCALE_DEFAULT);I then copy the Graphics from the Image to another Graphics before it is sent to the client (have some cache-stuff going on in the middle), but all images turn out beeing plain black.
Anyone with ideas/sample code?

hi flaperman
i did something similar in my resizing servlet:
BufferedImage image = ImageIO.read(new File(path));
Image im = image.getScaledInstance(width, height, Image.SCALE_FAST);
BufferedImage thumbnail = toBufferedImage(im);
ImageIO.write(thumbnail, "jpeg", response.getOutputStream());
i found the code of the method toBufferedImage() on the following page http://developers.sun.com/solaris/tech_topics/java/articles/awt.html
maybe this will help you. but i'm afraid it is slow and it seems to be leaking memory (a lot).
cheers

Applet without JMF installation at client side

hello,
I am trying developing an applet SIP phone based on Jain Sip Applet Phone( which originally can only deal with audio signal). But I found a big problem that I have to make every client install the JMF, however the clients hope there is no software to be installed locally.
In application, I can run it without JMF installation by copying all the dlls to system32 directory and add some related JMF source code into my own project. Or just simply put the jmf.property to the "lib" directory, which also works.
However, as for the applet, it dosen't that simple for the security thing. Here is the output in cosole:

java.lang.RuntimeException: No permission to capture from applets
-> Couldn't connect to audio capture device
java.lang.RuntimeException: No permission to capture from applets
-> Couldn't connect to video capture device
      I found that my applet can detect two device which is correct but has "no permission to capture from applets".
      In the progress of installation the JMF, and option is "permit recording from an applet". I read the source code, and found it dose the following works:
      if I choose "permit recording from an applet", then "allowCapture=1", and in "settingPanel.java" it dose:
     "boolean allowCapture = checkAllowCapture.getState();
      Registry.set("secure.allowCaptureFromApplets", new Boolean(allowCapture));"
      I want to do what the installation progress did to give permition to applet, however, when I do the following:
       private static final String PROP_ALLOW_CAPTURE_FROM_APPLETS
        = "secure.allowCaptureFromApplets";
       Registry.set(PROP_ALLOW_CAPTURE_FROM_APPLETS, new Boolean(true));
       Registry.commit();
      in my project , it throws exception like this: "Failed to initially commit JMFRegistry. Ignoring err.java.lang.SecurityException: commit: Permission denied"
      The code which i thought could give applet the rights is denied.
      Till now, I have also read some similar questions in different forums, but there is no good answer.
      Can you help me? Is there any possibility to run the applet without installation on the client side ? Is my method right? If not, how should I do?

BTW - have you investigated JavaFX? It is effectively the replacement for JMF, and possibly has a better end-user experience than trying to install JMF.
However, as for the applet, it dosen't that simple for the security thing. Here is the output in cosole:

Imagine if you visited a web page with a 1px x 1px applet (effectively invisible) that could hear everything you say, and transmit it back to the server. Sun is not about to allow that, unless the end-user has granted the applet extended permissions.
