[flexcoders] TIF to JPEG Converter Using ActionScript
Since the ImageViewer control doesn't handle the TIF foramt, We are thinking about using server side conversion using Sun's JIMI. But, we are not sure if that is going to be a performance bottleneck in a multi-user environment (J2EE App on the server side doing the conversion using JIMI). Has anyone come across a client side TIF to JPEG converter that is based on ActionScript? Regards Hari Kolasani

Kwong wrote: I'm really at a lost as to how we're supposed to work with the hierarchical data that's used with the Tree component. The XML approach seems to be the most supported at the moment, so consider this simple XML: var rootNode: XML = node label="Root" node label="Child1"/ node label="Child2"/ /node The dataProvider for the Tree then becomes an XMLListCollection. It displays fine. But now what's the expected way to modify the data so that the Tree updates? From the docs, I read: "You can use the ICollectionView interface with list-based or hierarchical data. The following sections describe the basic ICollectionView operations using a list-based collection, but can also apply to similar operations on a hierarchical collection." How is ICollectionView used with hierarchical data? Michael Montagna gave a hint in the quoted code at the bottom, but it seems like XMLListCollection is no more hierarchy-aware than ArrayCollection. If I use a cursor with the above example, I find that the collection has just one item--the root node. I can add siblings to the root node via the cursor, but that's not very useful. How do I get to the children via the collection/cursor? So then I tried modifying the XML objects directly. I tried doing this: [EMAIL PROTECTED] = "Hello"; And to my surprise, the Tree updated! So I thought this was the answer. Well, sort of. With the root node open in the Tree, I tried this: rootNode.appendChild(node label="Child3"/); The Tree does update itself with a new row, but it shows up empty (I can select it, though). If I collapse and expand the root, Child3 shows up ok. Now, if I try this: rootNode.node[1].appendChild(node label="Child3"/); The Flash Player crashes, taking the browser with it. Looks like converting a leaf to a branch while it's being displayed is a no-no. Works ok if the root node is collapsed.
