I’ve created an flash application that will post variables to a PHP page. This PHP page will then take the variables and using GD Libraries, create a JPEG image on my server and save it. I’m writing in AS3 based on the AS2 tutorial I found here.
The variables I’m sending are height and width of the image, and then a very long string containing all the values of the pixel colours, with rows and columns separated by characters. (ie ffffff,dddddd-aaaaaa,cccccc). The example here is only a 2×2 image, so a small 400×300 image is 120,000 pixels x 6 characters = 720,000 characters + all the separators! This method is working quite well, but can take about 20-30 seconds to send on a slow connection.
My explanation is very long but the question is quite simple. I know you can get progress events and bytesTotal and bytesLoaded on incoming URLVariables, but has anyone discovered a way to track the progress of sending out variables?
Any help is much appreciated
