Camera.takePicture

From GiderosMobile


Available since: Gideros 2021.8
Class: camera

Description

Take a picture. This function must be called while preview is active, that is Camera.start() has been called. If it returns true, then the platform will asynchronously take a picture from the Camera (eventually using flash) then call Camera.onEvent callback one or more times.
It is your responsability to define Camera.onEvent before calling Camera.takePicture(). Camera.onEvent function takes two arguments:

  • a number, indicating the type of event
  • a data buffer (string) depending on the event type

Event types are:

  • 0: shutter sound is triggered, data is empty (if supported)
  • 1: uncompressed image ready, data contains the uncompressed image (android only, optional)
  • 2: jpeg image ready, data contains jpeg image. This event is always fired if takePicture() was successful
(boolean) = camera.takePicture()

Parameters

Return values
