LokPix Gallery Buttons
View a Picture
The built-in View module lets you see your photos in greater detail. You can zoom in and out, and pan around the zoomed-in Picture. When you tap the View button, LokPix must decrypt the primary image file:
This can take some time (5-20 seconds), depending on the size of the picture, and the strength of the encryption. You may of course, cancel at any time, but you won't be rewarded with your picture in that case...
Here are the controls for the Viewer:
Tap the screen - zoom into the Picture.
Long tap (hold your finger on the screen for a few seconds) - zoom out
Trackball up - zoom in
Trackball down - zoom out
Trackball click - reset to the original view
Slide across the screen - pan across the zoomed picture
Back - return to the Gallery
Export a Picture
If you want to do more with your pictures than just look at them in the Viewer, you'll need to get them somewhere else in a format that other applications can understand. This button lets you export a decrypted copy of the current picture into the /sdcard/dcim/Camera directory on the SD card, which happens to be where the Android Pictures application expects to find it.
Note: Obviously, this removes the privacy from the exported picture. The new copy is not encrypted, and may leave traces on the SD card, even after it's deleted.
This is what it looks like:
You have two options here. [Copy] puts a decrypted version of the photo in the Pictures application, and leaves the secured copy in the Gallery. [Move] decrypts the photo just like [Copy], but then securely deletes it from the Gallery.
The photo in the Pictures directory will have the same numeric filename that it did in LokPix, except the extension will be changed to ".jpg".
Import a Picture
This button allows you to import a photo taken with the default Android Camera application into the LokPix encrypted Gallery. It will be saved under the current passkey, just as if you had taken it with the LokPix Camera.
Once you select a photo from the Android gallery, you will be prompted to Copy or Move it. The Copy option creates an encrypted version in LokPix, and leaves the original in the Android Gallery. The Move option, on the other hand, overwrites and erases the original after it's been secured in LokPix. If you check the Android Gallery after a Move, you'll find that it's not there anymore.
Importing and encrypting takes just about as long as capturing and encrypting a photo - up to 15 seconds for the highest level of encryption. Don't rush it.
LokPix doesn't keep track of how many times you Import a photo - it'll happily create multiple copies in your Gallery, until you reach the limit, or fill your SD card. The newly-imported photo will have a different filename than the original one.
Note:
It is entirely possible to Import a picture that's too large to view with the Viewer. This is because the Viewer has to load the entire image in the phone's limited memory, while the import and Export functions work on a smaller chunk of the image at a time. Your large photo is still safely encrypted, you just have to Export it to view it at full size.
Erase a Picture
This is how you get rid of the clutter. To permanently delete a picture from the Gallery, select it then press this button. You'll be prompted to make sure:
If you click [Yes - Erase], the file is over-written with zeros, and then deleted. This, combined with the encryption, should be enough to prevent anyone from recovering this picture. Including you - so make sure you really want to do this.
There is an option in
Gallery Settings to prevent anyone from Erasing a Locked picture.
