I think MOVE effects may use bitmap caching, but I don't think RESIZE does.

I know I've put effects I didn't need on certain components that contained textFields that weren't behaving properly (such as the text ignoring .alpha and such). -J On Wed, May 28, 2008 at 1:06 AM, Alex Harui <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: I'll have to ask the player rendering guys for the exact answer. I do know the player works in 20ths of a pixel, so that'd be my first guess. I'm not sure what you mean in the last question. Effects or no effects, all transforms we do attempt to not use bitmaps (unless the raw data is a bitmap), in order to get highest-fidelity. ________________________________ From: [email protected] <mailto:[email protected]> [mailto:[email protected] <mailto:[email protected]> ] On Behalf Of Josh McDonald Sent: Monday, May 26, 2008 10:01 PM To: [email protected] <mailto:[email protected]> Subject: Re: [flexcomponents] Fwd: Center/Shrink To Fit Yeah you're right, my bad :) As for scaling - I'm definitely not as knowledgeable as I'd like to be about what goes on (when dealing with non-bitmaps). What does flash do if you scale down rather than up? Does it scale drawing commands to sub-pixel values? What about stroke widths? Do they bottom out at say 1 or half a pixel? If you have an effect on your component, does it scale and then convert to bitmap? -J On Tue, May 27, 2008 at 2:39 PM, Alex Harui <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: I'm not sure you can get at _scaleX in the override. I would override invalidateSize() and have it check a flag as to whether to call the default behavior. That's what happens in ListBaseContentHolder. Going to bitmap will have smoothing problems when scaled, and take up much more memory in most cases. ________________________________ From: [email protected] <mailto:[email protected]> [mailto:[email protected] <mailto:[email protected]> ] On Behalf Of Josh McDonald Sent: Monday, May 26, 2008 9:37 PM To: [email protected] <mailto:[email protected]> Subject: Re: [flexcomponents] Fwd: Center/Shrink To Fit That's a great idea Alex - subclass Canvas for your scaling child, and override set scaleX and set scaleY like so: override public function set scaleX(value:Number):void { if (_scaleX == value) return; _scaleX = value; invalidateProperties(); //invalidateSize(); dispatchEvent(new Event("scaleXChanged")); } Although I think that will come back to bite you if you ever have something else that changes the scaleX or scaleY on that component, as your container probably won't be notified about the different size. Of course, if there's no interaction with the object you're trying to scale, I'd probably just render it to a bitmap and display that at whatever size you please. Seems less hacky. -J On Tue, May 27, 2008 at 2:02 PM, Alex Harui <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> > wrote: One way is to block invalidateSize when scaling the child.

I'm thinking maybe I should emulate SWFLoader and use a DisplayObject as "content container". Advice appreciated. ---------- Forwarded message ---------- From: Richard Rodseth <[EMAIL PROTECTED] <mailto:rrodseth%40gmail.com> > Date: Fri, May 23, 2008 at 5:00 PM Subject: Re: Center/Shrink To Fit To: [EMAIL PROTECTED] <mailto:flexcoders%40yahoogroups.com> Is there a way to set the scale of a component without triggering invalidateSize() ? My initial effort to create a "ScaleToFit" component involved setting scaleX and scaleY in updateDisplayList. But that results in some recursion. Perhaps this is the wrong place to set the scale. I notice that SWFLoader uses a DisplayObject as a content holder, but my attempts to cast "this" to DisplayObject before setting the property didn't help - the UIComponent version of "set scaleX" is still invoked.
