Reading checkboxes's values

Re: Reading checkboxes's values
Nancy: If you only want to select one color, why not use radio buttons instead?

Re: Any idea of how to draw a line or a square on top of an image?
Julia, I think the only way to place an image on top of another image is through Cascading Style Sheets (CSS) absolute positioning. This is not supported in older browsers and can be tricky to manipulate though. Depending on what you are trying to do, you could get the appropriate request paramaters and manipulate an inline styelsheet and/or the square img width= and height= tags. By dynamically getting the width and height tags from a users input you could manipulate the size of the sqaure. Hope that helps...

Re: Any idea of how to draw a line or a square on top of an image?
Hi Julia, You can just read the image into a BufferedImage, then use any of the Java drawing commands to write text or graphics on it, then use com.sun.image.codec methods to convert the BufferedImage to whatever format you want, then send it. You can read the image in from disk or you can grab it from the page in memory by saving it in the session, for example. Rick Hello everyone: I have an image in a page, and I need to paint a square (or 4 lines )on top of it depending of certain parameters, to represent a selected area. Any idea of how can I do this? Or how can jsp help to do this? Thanks a lot, Julia === To unsubscribe: mailto [EMAIL PROTECTED] with body: signoff JSP-INTEREST.

Re: Reading checkboxes's values
