Android Question Capturing an area of a photo using Mediachooser for TextRecognition

There is no built-in (standard) crop feature. You can implement one yourself using one of the libraries: https://www.b4x.com/android/forum/pages/results/?query=crop

Thank you Erel.


When using the crop library, does the "crop" only happen after a full-size photo is taken?

My intention is to adjust the "size" of the image captured by camera. And the users should know what area (i.e. only a rectangular area at the centre of their screen) they are capturing even before they press the shutter.

After. If you want to have more control over the camera then use CameraEx or Camera2 library instead of MediaChooser and capture the photo from inside your app. The downside is that it is more difficult to implement and requires the camera permission.

Thank you Erel
