Flash :: Flex - Client-side Image Processing?
Sep 20, 2011
I'm creating some image uploader in Flex with client-side image processing. Processing consists of two steps:
1. Resizing (solved)
2. Converting resized image (represented by ByteArray in PNG32 with alpha-channel) to gray-scale PNG with bit-depth = 2 and no color-palette. Is there any existing library that is capable of second step? Something like libpng for C++, maybe?Edit:It seem I stumbled upon rarely encountered problem. However my descision was to create an AS3 class that is capable of converting bitmapData to 2bit grayscale PNG. I used standart PNGEncoder and PNG format specification (which is not so good as I expected) as basis.

We're building a web-based application that requires heavy image processing. We'd like this processing load to be on the client as much as possible and we'd like to support as much platforms (even mobiles) as much as possible. Here's the info: Image processing is rasterization from some data. Think like creating a PNG image from a PDF file. We don't have a lot of server power. So client-side processing is a bit of a must.
So, we're considering: Flash - most widespread, but from what i read has lackluster development tools. (and no iPhone/iPad support for now). Silverlight - allows us to use .NET CLR, so a big ++ (a lot of code is in .NET). But is not supported for most mobiles ( rumored android support in the future) HTML5 + Javascript - probably the most "portable" option. The problem is having to rewrite all that image processing code in Javascript.
Clarification: I don't need further ideas on what libraries are available for Silverlight and Javascript. My dilemma is choosing Silverlight means no support for most mobiles choosing Flash means we have to redevelop most of our code AND no iPhone/iPad support HTML5 + Javascript we have to redevelop most of our code and not fully supported yet in all browsers choosing two (Silverlight + Flash) will be too costly Any out-of-the-box or bright ideas / alternatives

I want to create an application that has these features
- At client side: Display a list of images, when user click on one image, data will be stored in MySQL database.
- At server side: Manage images used in client side, I can delete, add new images.
Is this possible for me to achieve this using Flex? And if it is able, will my output be 2 separate SWF files? And where can I find the materials to read on writing such applications?

I am creating client side PDF with image using flex and AlivePDF for a web based application. Images have been generated on that pdf but it is creating problem for large size images as half of the image disappeared from that pdf. I am taking the image inside a canvas. How do I control my images so that they come fit on that pdf file for any image size that I take.

I'm rather inexperienced with flash and as3, and I've been given a task of writing a program that downloads images from URLs that are provided, and saves them to a specified location on the user's computer.
The idea is to be able to download multiple images (user selects them) and download them all to a single directory (which the user selects first) so that he doesn't have to download them one by one. Also, putting them in an archive and downloading as one file wasn't an option.The only solution I found is using FileReference.save(), which won't work for me because it opens a save dialog.

In flex, what we do, we normally upload the image from flex end and upload it to the serveri want to know, can we do some details checking, like i want to find out the imageesolution(on the client side) before it is uploaded to the server,There are going to be two profits, first the client doesn't need to wait for long to image get uploaded, and in case if finding the image resolution is on the server end, so it willtake time, even the image to be uploaded is not of expected resolutionsecond, the user interaction & interface with the flex application will be improved,

User interacts with Adobe flex webpage to configure reports based on some data stored server side. They configure their view and have THAT view emailed to them daily. I've got the report builder, the part I'm trying to figure out is how to render the report server side and send it out as email (native flex functionality? convert to html? take screenshot? assume something is running client side?...)

We want a web app that allows a user to edit images on the browser and we're trying to decide which technology to use. We want to support simple image customization, such as high-quality resizing, cropping, image merging, and color transformations, as well as the addition of text elements with different fonts and colors.
The current options are: Flash: no worries about cross-browser compatibility; could use same image library on client and server; no iPhone/iPad support. Java (compiled to javascript with GWT): need to find a good image library in pure Java so it can be compiled to JS. Plain old javascript + HTML5: may be a mess due to multiple browsers; may need to write image editing code from scratch. Here's what's most important to us / criteria for choosing:
Image consistency: the image that the client edits on the browser must be exactly the same as the one we'll eventually use on the backend. We can achieve this by (a) having the same library both on the client and server to process images, (b) having the client generate the image and upload it to the server, or (c) use two different image processing libraries on the client/server and hope for the best in terms of consistency.
Option (a) seems best, but it would only be possible if we use Flash or Java/GWT. We don't like option (b) because the images are large; we'd rather save a sequence of operations to perform on a raw image than saving multiple transformed images. And we don't really know if option (c) is safe or not. Scalability: We prefer the client to do as much work as possible to decrease server load. Image quality must be kept high
Cross-platform: We'd like to support as many platforms as possible without rewriting everything (big negative for Flash due to iPhone/iPads).

I have an upload form for an image. The user clicks browse and selects a file. How can I get the image dimensions the moment the user selects the file (before the file is even uploaded to the server). It obviously has to be something client-side with maybe javascript/jquery or flash/flex (prefer js//jquery though), but can either of them do this? This is the code I'm using to tie into zozo's getImgSize() function, but it gives me 0*0 as size.

We're writing a flash application that can download a MP3 file, convert it to a Sound object, get the raw data and make some processing (like adding sounds, change octaves). After the processing, we want to send the data back to the server in chunks, so the server will be able to glue the data together and recover the new generated file. The problem is: if we send to the server "wav" pieces of sound, we are able to glue them together without any problem in the generated file. However, if we convert each wav piece to a mp3 file (so we can send a smaller file to the server) and join the mp3 files at the server, the result is a sound with some problems at the merge point.
This is how we load the mp3 file from the server:
sourceSnd.load(new URLRequest("sample url to mp3"));
sourceSnd.addEventListener(Event.COMPLETE, carregou);
This is how we convert each piece of mp3 to bytearray and wav:

Since I'm developing a multiplayer card game for Facebook using Flex as client side and Java SE as server side, I wanted to know how do I actually make the connection between Flex and Java? the server and client should be able to send each other data(cards,movement,room information etc...) across and I wonder what's the easiest way to do it without complicating it. where to read about it ? I know JAVA but I find JavaEE hard to understand.

We are trying to create a sqlite db file using java on the server, and encrypt it.Then we send the encrypted db file to a client's pc, which has an Adobe Air desktop app running.The air app then needs to be able to open/read-from the encrypted db file (client is read-only).We are using java 1.6, flex/actionscript 4.5, and Air 3.1.We can create the sqlite db file on the server and send it to the client, and it can be read by the client without issues, when we do not encrypt it.But we are having trouble with the encryption part. We've read quite a lot of documentation about Actionscript's ability to open encrypted sqlite files using AES + CCM (URL...).And we're trying to use java's crypto package to encrypt the sqlite db file.The encryption is important because we don't want the client to be able to open the sqlite db file with any sqlite browser, only with our Air application.
