ActionScript 3.0 :: ImageSnapshot And PNGEncoder In Flash
Sep 27, 2010
As usual I've come across something easy to do in Flex but not in Flash. Flex has ImageSnapshot and PNGEncoder to get a .png out of a display object. Any way to do this in flash without using a 3rd party API as I can't distribute a license with my app. I'm using Flash CS5. I wish there was as much support for Flash as there is for Flex. I've had to write my own tree component, if I'd have used Flex I could have just used the Flex tree component. I'm hoping I don't have to write my own display object to png class myself.

I'm loading and displaying a large image say 6000 x 6000 px using an image tag. I wanted to take a snapshot of the image. But the maximum limit I get is 2880 px dimensions using Flex 4, flash player 10. Didn't the limit of FP 10 increased to 4096 px? Then why am I getting 2880? Is there a way to increase that size.

I'm trying to import an image and assign it to a Loader object, which works just fine, though I want to use the PNGEncoder rather than a the JPGEncoder, because if the source image has an alpha channel (transparency) I want that data preserved. The code, or the encoder, or something is preventing or deleting the alpha channel data. What should be transparent is showing as white.

I am creating a program that is effectively an sprite creator. I'm very new to AS3, but I know JQuery, JS, PHP, etc. After going through multiple steps of selecting pieces to customize a character, you are supposed to be able to download the final product using fileReference(). Everything works, and I can download the image in the end, but the problem is that I cannot capture all of several movieclips on the stage, I can only capture one. Maybe this will help clarify:

Could it be that each of the movieclips I'm adding to the sprite have children of their own?

I'm trying to take an ImageSnapshot of the whole stage in FlashCS5:
ActionScript Code:
// set up save image
var image:ImageSnapshot;
var fileSave:FileReference;
[Code].....
It works, but it takes the snapshot, that's in the upperleft corner of the image, and has this long black background.
Is there anyway to specify and print everything on the stage, and in the stages bounds?

I can take snapshot of a component. But the problem is the component is lil bigger with scroll bars. The saved image has scrollbars (only the visible area is getting saved). What i need is I want the entire component to be saved as an image.
This exact functionality is available while we print the component using FlexPrintJob, where by setting the FlexPrintJobScaleType.NONE.

I am trying to utilize the PNGEncoder with the dynamicfash Base64 to send a Base64 String to PHP and save the PNG File but for some reason that i cannot figure out, the PNG file is never readable. It is there and has a size (contains data) but cannot be opened by anything so is not a valid png file. Here is my code...
Code:
var target:MovieClip = new MovieClip();
target.graphics.beginFill(0xff0000,5.0);[code]..........

I'm trying to use PNGEncoder to encode a bitmapData object into a png ByteArray so I can send the data to the server. Everything would be peachy except the bitmapData is 4000x4000px and when I run the PNGEncoder.encode function on it the whole app stops (UI is blocked) for 5-8 seconds while it runs. Does anybody have any suggestions on how to not make it block so bad, I read about chunking up the process (since you can't multithread in AS3) but can't find any sample code on chunking up the process.

I have a large image that exceeds the bitmapdata limits, so I am trying to break it up into 4 separate images and encode them separately using the PNGEncoder. The first 1 comes out great. The remaining 3 all contain the same bytearray data and result in a blank image.
Code:
public function encodeUsersDrawing():void{
pngImageQuadrant1 = new BitmapData(1875, 2400, true);
pngImageQuadrant2 = new BitmapData(1875, 2400, true);
pngImageQuadrant3 = new BitmapData(1875, 2400, true);
pngImageQuadrant4 = new BitmapData(1875, 2400, true);

Also i understand that i only get 96dpi from image, because of my monitor dpi, but I need to make sure that even it generates 96dpi, it really is 300dpi quality.
I am taking 28 original images from user and making a "thumbnail picture collage" out of it for printing. I dont get the crisp quality in generated collage images, compared to originals. Here are my function, I really need to generate photo quality images for printing.
private function createImages(object:Object):void
{
progress.text = "Start Generating Images ( "+(index+1)+" - 28 )";
images_array.push(ImageSnapshot.captureImage(album.tilesList[index],30 0,new PNGEncoder()));

I'm working through Dreamweaver fairly well, and I'm now wanted to import Flash buttons I've created myself into Dreamweaver for a website I'm currently building, and it's here that I'm finding the problem. I have been to the 'get URL Function', but it says something about needing to link to a web page? But my problem is how can I link Flash Buttons to a web page, when my site is still being developed and not published? Do I have to publish first?

Are there any programs or features in flash that can simplify flash vector art?
I just realized that one of the reasons why my program might be running so slow is that I made the images out of lots and lots of circles. When things didn't look right I often just put larger circles over smaller ones. I didn't think that flash might still be drawing the invisible circles underneath-

We've got a green screened video playing in a flash movie over top of our html content.when the movie ends, flash uses external interface .api to call a javascript function which swaps the flash movie out with a 5 x 5 pixel flash movie (rewrites the <div>).this works and you can interact with the html content after the flash movie in all browsers except firefox.anyone know of any work-arounds or is there a better way of handling flash over html in this fashion?

We are developing our app in flash/flex builder for the front end hitting .NET backend webservices. There is one section of the old app that will not be initially converted, so we need have it appear in an iFrame.
So far all that works fine.We shrink the size of the SWF in the host page to just be the menu/nav area. And underneat that I have an iframe control that loads in this page from the old site.Now the problem. in the SWF is a drop down list to enable picking a client. Since the SWF has been shrunk to about 100px high, the drop-down will only occupy within that 100px area which it's opened. This is NOT good as you can imagine. How can I make the drop-down list descend over-top of the IFRAME control and thus extend outside the SWF dimensions? Is this possible?
I tried to make the internal stage transparent and leave the SWF a little larger, about 400 px high, but the IFRAME still appears behind the SWF.

Is the Flash Video (or Flex VideoDisplay) component capable of seeking to an exact moment in a video?It seems to always 'snap' to keyframes (which is understandable). I'm just wondering if there are any mechanisms in the video classes for seeking to exact frames, ie it should do the translation from keyframe to specific frame in the background rather than having to actually play the video forward to the desired frame.This is not a streaming file and has nothing to do with buffering. The player is just downloading a movie file from the web and playing it from memory.

Situation: Got a flash object with an icon bar (div with pngs) on top of it. Works on all browsers except Firefox 3.6 on Ubuntu 8. Example: http://ListAndPlay.com
Problem: Icons suddenly disappear after the flash is being loaded. See this screenshot: http:[url]...What I've tried: Setting z-index, recoding the JQuery behind it, nothing works.
