1 | FileToDataURI
2 | =============
3 |
4 | **EDIT**: [FileReader](https://developer.mozilla.org/docs/Web/API/FileReader) should now be [safe to use](https://caniuse.com/#search=FileReader) instead of involving Flash.
5 |
6 | A cross-browser solution to read a local file and provide the base64 encoded content with Flash.
7 | See the [example](http://aymkdn.github.com/FileToDataURI/) to know how to use it.
8 | The example provides a polyfill-like solution (based on this swf file and on the FileReader API when available).
9 |
10 | You'll need to define in your JavaScript the below code:
11 | ```
12 | var Flash = {
13 | getFileData: function(base64) {
14 | /* this function is mandatory to deal with the base64 for the Flash version (old browser) */
15 | },
16 | getButtonLabel: function() {
17 | return "Load your file";
18 | /* you can use this function if you want to customize the button label for the Flash version (old browser) */
19 | }
20 | };
21 | ```
22 |
23 | Customization
24 | =============
25 |
26 | 1. Do the changes you need in the mxml file (Flex);
27 | 2. Download the [Flex SDK](https://www.adobe.com/devnet/flex/flex-sdk-download.html);
28 | 3. Unzip and open a console;
29 | 4. Run the following command:
30 | ```
31 | $ ./bin/mxmlc FileToDataURI.mxml
32 | ```
33 |
34 | You'll have some warning messages as below:
35 | > Chargement du fichier de configuration D:\flex_sdk_4.6\frameworks\flex-config.xml
36 | > RSL requis :
37 | > http://fpdownload.adobe.com/pub/swz/flex/4.6.0.23201/framework_4.6.0.23201.swz avec 1 basculement.
38 | > http://fpdownload.adobe.com/pub/swz/tlf/2.0.0.232/textLayout_2.0.0.232.swz avec 1 basculement.
39 | > http://fpdownload.adobe.com/pub/swz/flex/4.6.0.23201/spark_4.6.0.23201.swz avec 1 basculement.
40 | > http://fpdownload.adobe.com/pub/swz/flex/4.6.0.23201/sparkskins_4.6.0.23201.swz avec 1 basculement.
41 | > http://fpdownload.adobe.com/pub/swz/flex/4.6.0.23201/mx_4.6.0.23201.swz avec 1 basculement.
42 |
43 | But it will work and you'll find the *FileToDataURI.swf* file in your working directory.
44 |
45 | Inspiration
46 | ===========
47 |
48 | Thanks to [Country/FileToDataURI](https://github.com/Country/FileToDataURI) for giving me the inspiration !
49 |
50 | Note
51 | ====
52 |
53 | For the first run, it's going to be a bit long to load the swf file. Actually the browser will connect to Adobe to download the swz files above. It's doing it just once, then no more download.
