I want to merge two JPGs (from the class javafx.scene.image.Image) using JavaFX 2.0.
I think one way should be to convert them somehow into BufferedImage (not sure how to do that), and then make it in the old Java way.
Is there any solution available for this in JavaFX?
Thanks!
I solved the problem. It seems there is no built-in function for this in FX (it should be available soon). I found this post:

With this class, you can save your node to an image file. I could use the output image as the merged one.
If anyone have a better solution, pease share it.

I need to merge two audio files together. Basically place one audio file on top of another and make one file. I have seen some posts on concatenating two audio files, but none on this. Thanks for any help.
I recommend you take a look at JSyn. I would discourage you to attempt to do it yourself, since it can get complicated with multiple audio formats. It supports a lot more as well.
This worked for me. Use jresources.org to help you. You could use their example: http://www.jsresources.org/examples/MixingAudioInputStream.java.html. For the org.tritonus.share.sampled.TConversionTool package, if you have problems using their library, then download their source code (http://sourceforge.net/projects/tritonus/files/): it's open source, and try using it. I tried it and it worked for me :D. I'm grateful for those guys!
I'm creating an android apps that use basic image manipulation (open image,copy, crop, paste).
Basically, the program will have multiple image input and it will be manipulated(copy, crop, paste). Then, an output image will be saved. I had done this in python using PIL library and would like to do the same using Java.
So, how do i do this in? Can someone point me a good library that have all the features? Thanks.
Hope this makes your work on this easy. I was going through some links and found this.
Let me know if you need anything else. Thanks.Image Manipulation in Java
I have a tiff image with many directories and subdirectories. I would like to navigate this tiff directory tree and import the image into a 2D array, so I can process this image. I am relatively new to java and cannot figure out how to do this. Will someone please reply to my question with a tutorial and examples of code?
Also, does anyone else find the java API documentation difficult to find, difficult to navigate, and somewhat sparse? I am trying to do this as a workaround for a processing sketch I am creating. Are there different workarounds?
Thank you.
Well i didn't even know a tiff could have directories and sub directories... But I would have a look in java File class as a start point to try to see those directories from your app. If you can see them, than you probably can parse them too.
Using Java I need to be able to create an empty CD image and also to inject/extract files into/from this image. Do you know any java libs for that? Is there a way to accomplish it without using JNI? (if not, then your JNI solution is appreciated). Thank you guys.
PS. This task is required for data transportation between emulated environment created by Qemu emulator.
In principle this is simple to implement, just write a file that is properly structured as CD-image. In practice thats probably a lot of work.
Simply googling for "java create iso image" reveal there is already an implementation to do just that: http://jiic.berlios.de/
I am working on google appengine to create a tool for comparing image similarity.
I need to extract the pixel values of each image to perform this.
Unfortunately appengine does not support the java image libs.So I am unable to proceed.
Is there any appengine safe image library in java capable of extracting image data?
I saw some techniques in python but dont want to switch to python if I can do it in java somehow...
GAEJ has its own graphic library with fairly limited features and java.awt.image.BufferedImage is a restricted class (ie, java.awt.Image is not supported and still not present in the Jre Class White List ).
There's an open issue here, that you might want to star.
EDIT:
Somebody has patched pngj to work with InputStream.(You could use it to read a PNG pixel by pixel)
The new version of pngj now an alternative pngj-sandbox.jar that only references whitelisted classes, it should run in google-app-engine.
can https://github.com/witwall/appengine-awt help to you? i believe it willbe enough to add theis lib as dependency to the project to make BufferedImage working (but havent' tried this yet)
