Thank you very much.

Hello friend kosglad
Thank you for your help, I apologize but I have no idea how to solve this problem, I don't even know where to start, where to move, this has never happened to me before.

check the pngencoder package 

mx.graphics.codec.PNGEncoder

Hello friend kglad
Once again, I thank you for your help. I did what you asked me to do. I read everything trying to understand how to solve the problem, but I confess that I could not understand how to solve it. I am not a Flash user with excellent experience like you, just a regular user. I apologize for not understanding how this type of problem works.
I really appreciate your attention.

remove your

import com.adobe.images.PNGEncoder;

and replace with

import mx.graphics.codec.PNGEncoder;

Hello friend kosglad
I still have the same problem, I think something is missing, my project is to take a photo with the Webcam and save it as a png or jpg, I have done other similar projects and did not have this problem.

[kglad]

maybe pngencoder is no longer part of the library.

you could download it and import it https://github.com/mikechambers/as3corelib/blob/master/src/com/adobe/images/PNGEncoder.as

Hello, my friend kglad
I really appreciate your help and patience. It really solved the problem. I created a folder next to my project and put the PNGEncoder.as file in it. Then I imported it. It worked perfectly.
However, I have a question. When I save the file, it says "This file type is not supported." Can you tell me if it's still a problem with Flash? Should I change something in my script?
I'm grateful.

Hi.

Use the BitmapData's encode method and the PNGEncoderOptions class. Like this:

import flash.display.BitmapData;
import flash.display.DisplayObject;
import flash.display.PNGEncoderOptions;
import flash.geom.Rectangle;
import flash.net.FileReference;
import flash.utils.ByteArray;

function snapshot(target:DisplayObject, fileName:String):void
{
	var bitmapData:BitmapData = new BitmapData(target.width, target.height);
	var byteArray:ByteArray = new ByteArray();
	var fileReference:FileReference;
	
	bitmapData.draw(target);
	bitmapData.encode(new Rectangle(0, 0, bitmapData.width, bitmapData.height), new PNGEncoderOptions(), byteArray);
	fileReference = new FileReference();
	fileReference.save(byteArray, fileName);
}

snapshot(yourContainer, "capture_" + new Date().time + ".png");

Regards,
JC

Vou tentar isso tambem, apesar que deu certo, apenas quando salvo o arquivo e quando tento abrir, ele diz que "Não tem suporte para este tipo de aquivo", será que ainda é algum tipo de problema com o Flash ??

The code exports a .png but it seems you're opening a .jpg.

Make sure the extension is correct.

[kglad]

or you can use JPEGEncoder class (using the same link).

Hello my friends kglad and JoãoCésar
I managed to solve the problem, it was really the JPGEncoder, the path inside the ".as" needed to be changed too, and soon there was also a problem in the BitString that I already knew how to solve, I changed my code using "ByteArray", then everything worked perfectly.
I owe you a huge thank you for having the patience to help me because it was by following your instructions that I managed to solve it.
I am happy to be able to count on you.
Thank you very much.
