[flexcoders] Resizing Images.
Hello! Our application needs the ability to take a logo (which gets uploaded in a different interface via rails) and resize it dynamically depending on which item they are purchasing. As of right now, I am using a Loader and when Event.COMPLETE is dispatched, I catch it, create a new width/height, call myMatrix.scale(newW,HewH), than bitmapFill on a UIComponent using the bitmapData and my matrix. Everything works, in that it does resize the image, but they quality is not very good, some of them are decent looking, and others do not handle aliasing well at all. Smoothing is set to true when I do the bitmapFill. Is there a better way to do this? Should I be creating a new image with the data rather than resizing the data dynamically? Halp! :( Thanks!
[flexcoders] Resizing Images
Hi. I have a space that is 175x100 and I am loading images into it on the fly. I am loading images that are as big as 200x115 and I need to shrink them to fit but also preserve their quality. If I don't specify the Image component's height and width, the image retains its quality, but it also retains its own unique height and width, and could spill outside of my 175x100 box. I then turned on the scaleContent property and set the horizontal and vertical align to center/middle. This solves the resizing problem, but not the image quality. The image looks jagged and smooth lines now look broken. Does anyone know of a way to keep an image within my constraints and retain image quality?
Re: [flexcoders] Resizing Images
Perhaps making sure that the resizing snaps to pixels. I have the same issue on mine and I'm trying to find a solution too. I'm thinking of using server-side resizing to get it to work neatly.

RE: [flexcoders] Resizing Images
There is a .smoothing property that you can apply to bitmaps/bitmapData, which is probably what you're looking for. On a quick check it looks like the Image component doesn't expose it (Ely Greenfields superImage component might?), and offhand I'm not sure if you can just apply it to the source bitmap (if that's what you're using). Sorry I don't have the whole answer just at the moment (I don't use the image component, in general), but hopefully it might set you on the right track for a google. -Original Message- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Chris Ivens Sent: 25 June 2008 15:49 To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Resizing Images Perhaps making sure that the resizing snaps to pixels.

Re: [flexcoders] Resizing Images
Yes, I think SuperImage does that, and I've seen other blog posts address this. Example from Googling flex image smoothing: http://weblogs.macromedia.com/mc/archives/2006/09/enable_smoothin.html Hope this helps.

Hi, i have a little problem with a TileList in Flex 1.5.
The cellrenderer of my TileList, is a Thumbnail.mxml that´s only has
an mx:Image:
?xml version=1.0 encoding=utf-8?
mx:VBox xmlns:mx=http://www.macromedia.com/2003/mxml;
horizontalAlign=center
verticalGap=0
width=100%
height=100%
hScrollPolicy=off
vScrollPolicy=off
mx:Script
var element:Object;
var thumb:Object;
function setValue(str: String, item: Object) {
if (item==undefined) {
visible = false;
return;
} else {
element = item;
thumb = element.REPRESENTACIONES;
visible=true;
}
}
/mx:Script
mx:Image id=image
width=100
height=100
source={thumb.THUMB}
horizontalAlign=center
verticalAlign=middle
scaleContent=true/
/mx:VBox
I have an mx:HSlider that´s determine the size of the tilelist´s
items. When i change the value of HSlider, the size of items changed
too, but the image dissapear.
Anyone can help me?

RE: [flexcoders] Resizing images in a TileList
Hmm, is the tile too small for the image
now? What happens if you re-assign the dataProvider after youve
adjusted the slider, do the images appear?
