Basic Picture Viewer
|
||
|
|
====================
|
||
|
|
|
||
|
|
This simple image browser demonstrates the scatter widget. You should
|
||
|
|
see three framed photographs on a background. You can click and drag
|
||
|
|
the photos around, or multi-touch to drop a red dot to scale and rotate the
|
||
|
|
photos.
|
||
|
|
|
||
|
|
The photos are loaded from the local images directory, while the background
|
||
|
|
picture is from the data shipped with kivy in kivy/data/images/background.jpg.
|
||
|
|
The file pictures.kv describes the interface and the file shadow32.png is
|
||
|
|
the border to make the images look like framed photographs. Finally,
|
||
|
|
the file android.txt is used to package the application for use with the
|
||
|
|
Kivy Launcher Android application.
|
||
|
|
|
||
|
|
For Android devices, you can copy/paste this directory into
|
||
|
|
/sdcard/kivy/pictures on your Android device.
|
||
|
|
|
||
|
|
The images in the image directory are from the Internet Archive,
|
||
|
|
`https://archive.org/details/PublicDomainImages`, and are in the public
|
||
|
|
domain.
