Hello,

Anyone have any recommendations on an open source library I can use to create Images from  user uploaded images.  I have the file upload part working but I need to take that image and create a two new ones with a default width and a height that is in proportion and then store those on a linux box.  Thanks for the suggestions!

You mean you want to scale the pictures?
What is the format of image files which your are uploading?

Try JMagick - it's fast and you'll probably find that at least some of the dependencies are already installed:

A user is uploading files of type jpg, gif and png and then I need to take those and resize them.  One a thumbnail and one a larger image.

you would either read image from stream, or read it from a the byte array read from user using ImageIO
then you can resize it using Java2D

Where I'm not sure is that I can go one of two routes.  I can store the uploaded file in some temp directory and create two images from it or I can convert the upload image into a byte[].  What is easier to work with?  I just need to take the incoming file and create a 200x200 and a 800x800 image from it.  Thanks for all the help!

you don't need to create a file, you can process the image directly

>  or I can convert the upload image into a byte[].

the uploaded image should already be a byte array

Objects,
I have the below code I want to use but instead of a file I have a InputStream inputStream = event.getFile().getInputstream(); How do I create a BufferedImage using an InputStream?  Thanks for all your help!


BufferedImage image = ImageIO.read(new File("C:\\Users\\User\\Downloads\\picture.jpg"));

For InputStream 'in':


BufferedImage image = ImageIO.read(in);

Open in new window
