Hi take look at the flash.display.LoaderInfo; after the open event, you can target the myLoader.LoaderInfo.height Cato Paus --- In flexcoders@yahoogroups.com, "Jayson" <[EMAIL PROTECTED]> wrote: > > I'm having a problem similar to this one.. is there a way to get the > height of an image that is being loaded? > > I looked to be able to do this in the asp script I have generating > the XML document, so I could have this in the XML, but I couldn't > figure out how to do it.

[flexcoders] Re: Convert ByteArray to Bitmap
I'm having a problem similar to this one.. is there a way to get the height of an image that is being loaded? I looked to be able to do this in the asp script I have generating the XML document, so I could have this in the XML, but I couldn't figure out how to do it. I figured I didn't need the width or height because the image could be scaled, but it turns out that I do need the height. Anyone know how to do this or is able to point me in the right direction? Thanks..

[flexcoders] Re: Convert ByteArray to Bitmap
If you're loading an image type supported by Flex (gif, jpeg, png, swf) then you don't need to know anything about the image. You don't need to know the width or height. All you do is use Loader.loadBytes(byteArray). This would load the image exactly the same as if you loaded from a URL.

[flexcoders] Re: Convert ByteArray to Bitmap
I agree with Franto friend: You need to know something about the bytearray you are receiving, i.e. format, disposition, etc. Most of image formats have a kind of header where you could find its width, height and so on. Once you know the dimensions and the format, you would need to use the apropriate decoder to transform the bytearray in pixels of a Flex Bitmapdata object. --- In flexcoders@yahoogroups.com, franto <[EMAIL PROTECTED]> wrote: > > if you dont know what is it ByteArray how you want todisplayit :) > you have to know at least 1 parameter, width or height... > > thats my opinion > Franto > > On 1/26/07, Steve Cox <[EMAIL PROTECTED]> wrote: > > > >All, > > > > > > > > I'm retrieving an image via remoting as a ByteArray.
