Re: byte array to Image

2011-09-18 Thread leandro borbosa
I also needed this one.
Thx for sharing !

 Hi All,

 Thank you so much for the many replies.
 Tried out the solution and library suggested by Xi just now, since his
 solution was the easiest to verify.
 It works.

 After having downloaded this library:
 http://sourceforge.net/projects/migbase64/

 I convert the byte string like this:
 String base64String = data:image/png;base64, +
 Base64.encodeToString(image,false);

 Then simply use it at the client side like this:
 Image image = new Image(base64String);

 The image now displays. I think the base64 library I initially used
 was not browser safe as Jens and Thad suggested.
 Would have build a servlet as Jens suggested if it had not worked.

 As for your question Alexandre, I don't know why the service developer
 suggested I could not use base64.
 Could have been inexperience on his behalf :-). Clearly base64 does
 work.

  Hi,
 
  I've usedhttp://sourceforge.net/projects/migbase64/in my

  pretty well and efficient
  My code is like : String base64 = data:image/png;base64, +
  Base64.encodeToString(bytes,false);
  And at the client side, you just set the value into an image
  element's src attribute.
 
  But be careful, IE CAN NOT take charge of an image that bigger
  than 32KB by using the Base64 way.
 
  Hope this can help you.

   Hi all,
 
   From a web service I am receiving a byte array that represents a
   image.
   I need to somehow squeeze this byte array into a image widget or
   similar widget on my client side.
 
   First I tried to convert the byte array to a base64 string:
   String base64 = Base64Utils.toBase64(image);
   base64 = data:image/png;base64,+base64;
 
   This didn't work. The developer of the web service informed me that I
   should not convert the byte array to a base64 string, and just use it
   directly.
 
   To test if the byte array represented a correct image, I saved the
   byte array to a physical image:
   InputStream in = new ByteArrayInputStream(image);
   BufferedImage bImage = ImageIO.read(in);
 
   File outputfile = new File(saved.png);
   ImageIO.write(bImage, png, outputfile);
 
   This succesfully resulted in a physical image being created.
 
   However I don't want to write the file and then send the URL to the
   image widget on my client side.
 
   Anybody have any suggestion about how I can get this byte array
   squeezed into a image?
   Or convert this byte array to a base64 string that does work?

Re: Gwt4Titanium Mobile 1.1.0 Preview: Introducing DevMode

I second Gal: great job Emitrom Team !
With DevMode this is a totally different story

I wonder how this work ?
Honeslty i doubted this could even be possible.
Did you wrote a plugin for Titanium Mobile similar  to the browser plug in ?
Most importantly  is the preview available somewhere to play with ?

 Hello folks,
 Some days  ago we introduced *  Gwt4Titanium Mobile*, which aims to give
 developers the ability to write* native mobile applications* for Android
 and  IOS
 by leveraging  *GWT* and the* Appcelerator Titanium Platform*. Next to
 provide a *100% coverage of the Titanium API*, we added other features
  like :

 - I18N Support.
 - GWT-RPC, RequestFactory as well as RequestBuilder
 - Dependency Injection support via GIN.
 - JSON and XML to POJOs support.
 - Event Bus support.
 - etc...

 But a really important part was missing: The ability to run and debug the
 Java code right frm the GWT project without compiling it to JavaScript.
 At Emitrom we have been working really hard to provide this missing part.

 With version 1.1 coming out soon we are glad to introduce* DevMode
 for Gwt4Titanium Mobile*.
 Please visit : http://www.youtube.com/watch?v=HYa_ctox6iw   to see it in
 action.

 We are looking forward to hearing your inputs.

 @Denis.
 The ActionScript part of gwt4air is not  opensource. Also i dont know if
 i ll open that yet. Need to think about it.

 @Leandro
 The idea of gwt4air started after we had a requirement to implement a web
 and a desktop client for the same application. We wanted to be able to do
 that using only one code basis. GWT provided us the right platform to do so.
 Because GWT generates HTML/JS and CSS we could deploy the same code to the
 browser and to AIR. Then  then client wanted to also hav a Flex widget on
 the web client (to enable client side PDF generation). Because i wanted to
  that using GWT I started looking for a solution. And the results of those
 researchs is what you see in gwt4air

 Hello Alexandro,

 Thank you for your kind words.
 I m glad that you like the project. I m also happy that it can help you
 solve some of the problems you have.
 Gwt4Air is  a free time project. We use it internally at the company i
 work but i dont get paid for that. It s small company so i decided to play
 the nice guy :).But I wish I could do this full time  dough.

 i m know the link you provided. As a matter of fact i have a comment
 there.
 While searching for ideas on how to implement the Flex API i came accross
 that post. What i did not like about that solution was the fact that the
 user must deal with both sides. Flex and GWT. I wanted a more simpler
 solution where one will only programm in Java like any GWT project.
 Hopefully i did a good job at that.

 Concerning what the Adobe Engineer told you: I think  what he ment is
 that  for every MXML based Flex project the MXML Compiler  does  some
 initialization work that you will have to do manually  if you dont want to
 use MXML. And that initialization is a quiet complex thing. So  he probably
 thought that no one would be crazy enough to try to figure out what the
 compiler really does . But because i wanted to use GWT to write Flex
 applicatons i had to be  crazy enough lol.

Re: Clientside file generation with GWT

You are really coming up with some incredible stuff lately man.
Clientside file generation is definitly something really needed.
The demo works pretty well.
Good work.

 Great work Alain!! Thanks for share it


 2011/6/12 Alain Ekambi jazzmatad...@googlemail.com

 Beeing able to generate files on the client is a common requirement  and a
 usefull  feature for a webapplication .
 In one of our applications for example we have users generating reports
 every 30-45 seconds. By beeing able to do that on the client we do not need
 to scale our servers when the number of users grows.

 Gwt4Air (http://code.google.com/p/gwt4air/)  introduced in version 2.1 a
 File API that uses Flex and let u create files(PDF , Excel, Text, PNG,
 JPEG...) on the client by adding a Flex widget into your GWT application.
 The problem with that approach is that you needed to load  an entire
 instance of the Flex framework just to be able to read/write files on the
 client

 Gwt4air 2.2 will introcude a more lightweigt solution that does not
 require Flex(Flash is still needed dough).  Please take a minute to visit:

 http://gwt4air.googlecode.com/svn/trunk/exporter/GwtAir.html

 to see the preview in action

 I m lookig forward to hearing your feedback.

Re: GWT meets Adobe Flex: gwt4air 2.1 is here !

2011-06-08 Thread leandro borbosa
This is a free time project ? ?
Really impressive stuff.

Hopefully i did a good job at that.
I  ve played around with the library i must say you did more then a good job
at that.
I still cant believe i m writing a Flex application.

I just wonder what makes you start this project. I mean Flex is not a small
framework. Exporting it to GWT must have been some hard work.

 Hello Alexandro,

 Thank you for your kind words.
 I m glad that you like the project. I m also happy that it can help you
 solve some of the problems you have.
 Gwt4Air is  a free time project. We use it internally at the company i work
 but i dont get paid for that. It s small company so i decided to play the
 nice guy :).But I wish I could do this full time  dough.

 i m know the link you provided. As a matter of fact i have a comment there.
 While searching for ideas on how to implement the Flex API i came accross
 that post. What i did not like about that solution was the fact that the
 user must deal with both sides. Flex and GWT. I wanted a more simpler
 solution where one will only programm in Java like any GWT project.
 Hopefully i did a good job at that.

 Concerning what the Adobe Engineer told you: I think  what he ment is that
  for every MXML based Flex project the MXML Compiler  does  some
 initialization work that you will have to do manually  if you dont want to
 use MXML. And that initialization is a quiet complex thing. So  he probably
 thought that no one would be crazy enough to try to figure out what the
 compiler really does . But because i wanted to use GWT to write Flex
 applicatons i had to be  crazy enough lol.

 cheers,

 Alain

 Hi,
 I just went to your project and i have to say this is just mind blowing!
 Are you doing this full time ?
 Really i wonder how you guyz come up with this kind of stuff.
 We have been struggling integrating  flex client into how existing GWT
 application.
 We ve tried this  solution here
 http://lgrammel.blogspot.com/2010/02/i-am-working-on-project-that-integrates.html
 but  that did not scale very well. Maintining MXML/AS3, JavaScript and
 Java in the same project is a nightmare.
 Last year at Adobe Max i asked an engineer at from adobe if it s possible
 to write Flex applications without using AS3 and MXML because we wanted to
 keep everything in Java
 and he basically said that s impossible. So i wonder how do you do this ?
 I  cant wait to play to hero tomorrow at the office when i present the
 solution that will solve our problems :)

 Good work man

 Alexandro
