EXIF Reader in Flex+AIR II

Now that files and folders can be selected, I move on to the next step, which contains the following substeps:

• Validating the selected files/folders
• Batch Loading the files
• On every file load, get the EXIF info for that file and save it as XML

A.Validating the selected files/folders

For the purpose of validating and loading Files I have created a class called "EXIFReaderClass"

<mx:Button x="10" y="534" label="Run EXIFReader" width="482" click="startReading()"/>

private function startReading():void{

             objEXIFReader.init(fsTree.selectedPaths)

}

The selectedPaths contains all the selections from the FileSystemTree component.

The validation is done in the EXIFReader Class:

EXIF Reader in Flex+AIR

Hi

I was posting some images on a blog, and I required to post the EXIF tags info there. It was a tedious job typing all those values, and I thought then to make a app that would do this for me.

First I tried .net, then on a search came to know of the EXIF Reader available on google code.

I then created this app for reading the EXIF tags on a image file using Flex and AIR. I will be posting the step by process I used for development.

Let me know if there are any issues or suggestions....

Step One: File and Folder Selection

The first step was to allow for file and folder selection. I used the FileSystemTree Component(AIR Only) for this purpose.

I added two buttons for file and folder selection and accordingly modified the FileSystemTree.

The mxml code for this :

<mx:FileSystemTree id="fsTree" enabled="false" showIcons="true" fileChoose="onChooseFile(event)" x="10" y="36" width="482" height="460"/>
<mx:Button id="fileBtn" x="103" y="504" label="Select A File" click="openDialogFile()"/>
<mx:Button id="folderBtn" x="275" y="504" label="Select A Folder" click="openDialogFolder()"/>

The methods for the file and folder selection are:

private function openDialogFile():void{

fsTree.enumerationMode = "filesAndDirectories"

fsTree.enabled = true;

fsTree.allowMultipleSelection=true;

fileBtn.enabled = false;

folderBtn.enabled = true;

}

private function openDialogFolder():void{

fsTree.enumerationMode="directoriesOnly";

fsTree.enabled = true;

fsTree.allowMultipleSelection=false;

fileBtn.enabled = true;

folderBtn.enabled = false;

}

This allows for file and folder selection.
