The JPGEncoder is buggy, because if i want to post/save jpgstream, the image file is corrupt (async and normal encode too)

When i use com.adobe.images.JPGEncoder it’s fine.

as3 post
var header:URLRequestHeader = new URLRequestHeader (“Content-type”, “application/octet-stream”);
var jpgURLRequest:URLRequest = new URLRequest (jpgSaveURL);
jpgURLRequest.requestHeaders.push(header);
jpgURLRequest.method = URLRequestMethod.POST;
jpgURLRequest.data = jpgStream;

var jpgURLLoader:URLLoader = new URLLoader();
jpgURLLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
jpgURLLoader.load( jpgURLRequest );

php
$img = $GLOBALS["HTTP_RAW_POST_DATA"];
$handle = fopen($fullFilePath,”w”);
fwrite($handle,$img);
fclose($handle);

[...] it’s class a little to implement asynchronous encoding and add merging method as in my previous example here. In the example below you can choose desired result image size and generate JPEG file. It generates [...]

Very nice script. I am using this to try and merge a bunch of different bitmapdata objects. When the total merged size is ~8000pixels it works fine, but as soon as I step up to 9000 it runs fast and stuff but the resulting merged image is just white with random black spaces, nothing at all like what i receive at 8000px. Any idea why this is happening and/or if it can be fixed/worked around? I think AS has a ceiling of like 8kx8k pixels but im trying this at 8kx100px and 9kx100px – any ideas or is this just a limit that can’t be worked around?

Thanks!
Dan

@squirtgun this encoder is specialy designed to work in Flash 9 and higher and the one from bytearray is for Flash 10 only. So you decide wich one you need.

Is there anything like this for the PNG encoder? Also, there is some great work being done over at http://www.bytearray.org/?p=775 to optimize the JPEG encoder using flash player 10 vector class instead of normal arrays. The speed increase is huge. Both of these combined would be great!

Also I have seen your Random class in Google Code (http://code.google.com/p/in-spirit/source/browse/trunk/projects/FlickrMosaic/src/ru/inspirit/utils/Random.as).
Maybe my fastRandom implementation, which is about 3 times faster than the built-in could help.
