I’m trying the .SWC in Flashdevelop with Flash CS4
error: ReferenceError: Error #1065: Variable de.popforge.imageprocessing.core::Image is not defined.

I don’t get it – why would I apply grayscale filter to an image which is already in grayscale format? :) I thought it would work as conversion from ImageFormat.RGB to ImageFormat.GRAYSCALE.

There are lots of uses for images which are not displayed. Your problem is that you apply a grayscale filter to an image which is RGB and this is probably implemented wrong.

I did not work on the library for a while, but grayscale filters are conversion only, so if your image is a GRAYSCALE format and you load a bitmap data into it the grayscale filter will be used for conversion.

I think it was like that.

Undoubtly it is more flexible now, but what is the use of image if you don’t want to display it? :) Ain’t gonna argue about this, I just thought it would be more intuitive like this:

[Embed(source = 'image.jpg')]
var imgAsset:Class;
var image:Image = new Image(imgAsset as IBitmapDataDrawable, ImageFormat.RGB);
addChild(image);

Nevermind, it is your project ;) Can you please tell what am I doing wrong here:

public class Test extends Sprite {

[Embed(source = 'image.jpg')]
private var imgAsset:Class;

private var image:Image
public var bitmap:Bitmap

public function Test() {

var imageSource:Bitmap = new imgAsset();
var image:Image = new Image(imageSource.width, imageSource.height, ImageFormat.RGB);
image.loadBitmapData(imageSource.bitmapData);

trace(image.format); //trace: 4

var g:GrayscaleRMY = new GrayscaleRMY();
g.apply(image);

trace(image.format); //trace: 4

addChild(new Bitmap(image.bitmapData));
}

}

The result is black rectangle..

Because everything is working on a BitmapData basis. There is no need to display anything basically. This would be an unnecessary overhead.

Hi joa,

Great work. I just have a little question – why does Image, Histogram, Layer etc does not extend DisplayObject class?

Cheers

Hi,

I’m trying to use your library in a Flex project.
How do I resolve ambiguous references between mx:Image and your Image class?

Thanks,

Hi Joa,

Thanks for publishing such a good image library!

I wish I can test it right now !
But the flex 2 sdk throw the same error as Jvy, “multiple point”.

How can we fix this ?

Thank you

Dear Joa,

First of all, very great work you have done and contributed. I am experimenting with face recognition and background subtraction for my college project and I found your site. However I am not able to import your ImageProcessing.swc either in the FLEX SDK or FLEX Builder. I am using Flex 2.0.143459 on WinXP Pro SP2. The error message is:

D:\Adobe\Flex2\Flex SDK 2\bin\ImageProcessing>..\mxmlc.exe -strict -optimize -l
.\swc\ -o .\lab.swf -use-network=false .\lab\Main.as
Loading configuration file D:\Adobe\Flex2\Flex SDK 2\frameworks\flex-config.xml
Error: unable to load SWC ImageProcessing.swc: multiple points.

I search around your blog and found that some other users have encounter similar problems. I hope to get some tips from you what went wrong.

Many Many Thanks Indeed, Danke!!

hi Joa,
cool stuff you have here, im eager to start playing ’round with it and get a real grasp of its power.
good work!!

Yes please (what Julian said) – or maybe some hints on installing the SWC directly to the Components. Everything I’ve tried hasn’t worked and I’m dying to give it a go in Flash CS3.

Hi Joa,

I was wondering if you where going to publish the .swc using Flash CS3 so we can use it for Flash. I am assuming it was built with Flex and I can’t seem to get it to work in CS3.

Hi Joa,
Thanks for the heads up i finally managed to get some working examples.. I was wondering if you could point me in the direction of a good tutorial that would explain to me a method for creating these kinds of effects, as i would like to ideally create some of my own and who know’s they might be good enough to add to your library.
Thanks for any advice, examples or tutorials.

It is comatible with Flex but a design bug indeed. It is possible (see the Battlebay using Flex) but you have to do somehing like image = new de.popforge.imageprocessing.core.Image();

Hi Joa,
This class seems cool however i was wondering if it is compatible with Flex?
I tried to add it as a library and i get a conflict error bcs you use some of Flex’s internal namespaces for example Image.
Is there a way around this or have you not published a Flex compatible version?
