Classes

TAccessCameraAppForm is the main form that represents the main window of the sample. It contains the following components:

• A TActionList object.

• A TTakePhotoFromCameraAction object

• A TImage object.

• A ToolBar object with a Tbutton and a TLabel object.

Implementation

• The sample uses TTakePhotoFromCameraAction to take photos from the camera device.
• The sample uses TImage to display and define 2D image components. When you run the aplication, the sample shows a picture and a button with the stylelookup set to cameratoolbuttonbordered. The TTakePhotoFromCameraAction is attached to this button. If you click the button, the camera window is displayed and allows you to choose the camera to be used (front or back) and to take a photo. Once the photo has been taken, the OnDidFinishTaking event assigns the image retrieved from the camera to the TImage component.
