resize outputstream

[Lalit Chattar]

hi everyone

i want to resize image in thimble preciew which is retrive from database as a outputsream. How we can resize outputstream in jsp.

Thank you..

You cannot resize the output stream. You need to resize the image.

There is nothing in JSP that will help you with this. You'll need to use a Java package (perhaps JAI) that manipulates images.

Moved to a more appropriate forum.

but i don't know how resize image in jsp. Can we temporary write image in server directory and resize then.

You could just use size attributes in the image tag. If that doesn't work, you could do a normal image transform and stream the resulting bytes--you don't need to write and read and entirely new file, although by doing so you'd have a "cached" transformed image.

Check out the following classes:
- ImageIO
- BufferedImage
- java.awt.Image

You can still use these without a graphical user interface.
