Image Encode with Flash and PHP
hi, this is a little project to save export/save images from flash.
This application allow you to see how to export in different image formats like: png, jpg and bmp.
I create class ImageCreator, whit it it’s this easy create images on server. You call the class like this:
1 2 | var imagecreator:ImageCreator = new ImageCreator(image_spr, ImageCreator.EXPORT_TYPE_PNG, name); imagecreator.addEventListener(ImageCreator.EVENT_COMPLETE_SAVING, completeWritingEvent); |
Event ImageCreator.EVENT_COMPLETE_SAVING, will be dispatched when image is correctly saved on your server.
This is ImageCreator Class
