I've seen this effect in Director, but when I try to replicate it in this platform, arise the problem of cross platform differences with the Ink effects. >The biggest problem I've run into is drag >performance with translucent objects. Does this happen even with the Alwaysbuffer set to true? Maintaining the fuzzy edges could be another real problem. There is stack in the Runrev users contributions area that shows how to use a small graphic inside an image to show parts of a large image. Like the pane windows of Photoshop. Maybe two stacks could do the same effect... >I've tried using a large PNG image that has a small >transparent spot in the middle: dragging response is >OK, but not good.

That could be an interesting sight. ;-) >Ideally I (we) need to be able to apply the blendLevel >to draw graphics but since the Rev folks >probably won't get to this any time soon, That probably will require to deal with the bitmap representation of vector graphics on the screen. Maybe SVG and Flash engines could provide to the RunRev team inspiration for this task. >Has anyone found a creative way to build an >irregularly shaped translucent object? Some time ago, I try to create a polygon graphic in a hidden (or out of sight) stack (this works), then take the imagedata of the windows of this hidden stack to create an image, (this works too), (see Ken Ray site) but when I try to set the transparency of the newly created image all I get is a crash. I left it for a while. If this method will work someday, then It could be possible to have infinite shapes for our stacks, because the vector polygon data is small compared to the bitmaps of images.
