Description

The Camera control lets you take pictures using your device's camera and display them in a PictureBox. The contents of that PictureBox can be saved in a database or sent to a server. All the settings needed to take a picture can be set at design time in AppStudio: no additional code needs to be written.

The default icon is a camera icon. You can change this to a different icon or text.

The control requires iOS7.1 or later. For Android web apps, use Chrome 31 or greater. If you are using VoltBuilder, use the cordova-plugin-camera plugin.

When saving to an SQL data base via a PHP script, the data can be corrupted. If you encodeURIComponent the Base64 string it is saved ok. As follows:

 postData = postData & "&imgBase64=" & encodeURIComponent(PictureBox1.toDataURL())
