Question

URGENT: Image manipulation with JSP or Java

Asked by: gbvreddy

Hello,

Trying to build a web application to do basic image manipulations like rotating and cropping. I kind of have an idea on how to handle this on the client side using javascript. On the server side, if I was using php I could have used something like ImageMagick to do server side processing of the image. Basically get the crop sizes and coordinates of the image from the javascript and pass it to the ImageMagick pluin in php to do processing for that image.

I want to know what similar options do I have when using jsp or any j2ee/java based solution?

I would use JMagick (Java port of ImageMagick)

 

by: objectsPosted on 2009-11-01 at 15:03:41ID: 25716078

no need to use external library with java it already includes image manipulation support with java2D

a. You know Magick
b. It's much better than Java's image support

 

by: gbvreddyPosted on 2009-11-01 at 16:00:29ID: 25716276

Thanks Objects and CEHJ. Both are very good solutions that I looked at.

 @ objects:- I like a pure java solution. But the image class is in the awt package. I am looking for a pure server side solution without any UI. I would like to take the parameters from the webpage pass it to a server side image processor and crop or rotate the image. I am not sure if the image class can be used without a GUI?

@CEHJ:- Is JMagick widely used? I appears to be fairly new. Also due to JNI, not sure of performance,scallability etc., We are planning to do some benchmarking.

Pure Java can be used if you set the System property java.awt.headless to true, but you'll get much better results from native code

 

by: gbvreddyPosted on 2009-11-01 at 16:07:42ID: 25716293

Thanks CEHJ. Have a few questions: Do you know if JMagick is supported on AIX? Can you point me to any good examples on using JMagick?

 

by: objectsPosted on 2009-11-01 at 16:11:03ID: 25716300

> b. It's much better than Java's image support

thats incorrect, all thats needed is a simple crop and rotate which java2d will do with a few lines of code and without having to import native libraries and all the associated overhead.

It does not require any UI

>  I am not sure if the image class can be used without a GUI?

It can

>  Is JMagick widely used?

I don't believe so, I've done lots of imaging work over the years and never come across a client that needed or used it.

 

by: gbvreddyPosted on 2009-11-01 at 16:14:38ID: 25716310

@objects:- Can I use it as a pure server side solution without a UI? Is the solution to set headless to true? or is there another solution?

Thanks for your help..

 

by: CEHJPosted on 2009-11-01 at 16:15:38ID: 25716312

There's no need to worry about which is better - just try them both ;-)

 

by: objectsPosted on 2009-11-01 at 16:20:28ID: 25716326

> @objects:- Can I use it as a pure server side solution without a UI?

yes

> Is the solution to set headless to true? or is there another solution?

headless has nothing to do with whether your app has a UI or not.

headless is used when you are running on a box without a monitor (or just a console)
and just requires setting a property in your containers startup options

I'm getting confused :-D

Which is exactly what's implied *is* happening
