The easiest option (imho) would be to use the java 2d api (should be perfectly safe in server mode) to find the image size on the server and use those values to write to your DirectArea.

Hi, everyone, I'm a beginner with tapestry 4 and got stuck with a problem for 3 weeks already... my task is: 1. create a dynamic image based on some data provided from user's input 2. create a buffered image and display that image on the page 3. use image map to make some regions of that image clickable now I've done the first 2 steps and part of the 3rd step. In step 3, I used @DirectArea custom component(explained in Tapestry in Action as well as used in the Pet Shop example) to create the image map, but I cannot dynamically specify the "coords" attribute in <area> tag which is inside <map> tag. @DirectArea component statically pre-defines the "coords" attribute in .html file(e.g. <area [EMAIL PROTECTED] listeners="ognl:listeners.selectPage1" coords="50,50 50,50" /> ), because as for Pet Shop example the image already exists whereas in my case that buffered image will be created dynamically and sends to OutputStream to display it. What I want is to take the "coords" attribute's value from user input at the same time in step 1 and specify the "coords" attribute(for example: pass "50, 50 50,50" as a string) for image map after creating the buffered image. should I modify the DirectArea.java? does anyone have any idea how to make it...? many thanks in advance. -- View this message in context: http://www.nabble.com/help-please%2C-problem-with-image-map-using-Tapestry-4-%21%21%21-tf1897938.html#a5192038 Sent from the Tapestry - User forum at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
