RecordTexture

This part presents how to display and record phone camera input.

Warning: Required configuration:
Audio and video nodes require a Java ME including JSR135 and MeMo player build with audio and video options.
Supported formats (for audio and video) depend of mobile phone.

Note:
Many MeMoPlayer versions does not support audio and video nodes.
To change the MeMo Player, add following line in your app.properties file.
player.name=OWP
RecordTexture node is not supported by MicroEmulator.
Install the Sun Wireless ToolKit to test video on PC.

We use RecordTexture to display and save picture/snapshot on mobile.
See RecordTexture documentation.

We define a RecordTexture node.
We define, via the fileUrl property, the target file (where snapshot is saved).

texture DEF recordImage RecordTexture {
  fileUrl "file:///root1/capture.jpg"
  singleShot TRUE
}

Note:
In example, we save snapshot in root1 folder.
On MS Windows, file is saved in C:\Documents and Settings\<user_login>\j2mewtk\2.5.2\appdb\DefaultColorPhone\filesystem\root1 folder.

In first time, we define a key to take snapshot. We use the left softkey...

# Key sensor to catch left softkey event
DEF KEY_SENSOR KeySensor { url "E" }

DEF SCRIPT Script {

  # Catch left softkey event
  eventIn SFTime pressTime

  url "
    //Call when left softkey is pressed
    function pressTime(time) {
      //Here, take the photo.
    }
  "
}
#Route key sensor to script event/function
ROUTE KEY_SENSOR.pressTime TO SCRIPT.pressTime

After, we use the startTime field of RecordTexture to take the photo.

# Declare RecordTexture field in script
field SFNode recordImage USE recordImage

url "
  //Call when left softkey is pressed
  function pressTime(time) {
    //Take the snapshot
    recordImage.startTime = time;
  }
"

Group {
  children [
    # Background
    Shape {
      appearance Appearance {
        material Material2D { filled TRUE emissiveColor 1 1 1 }
      }
      geometry Rectangle { size 300 300 }
    }
    
    # RecordTexture
    Shape {
      appearance Appearance {
        texture DEF recordImage RecordTexture {
          fileUrl "file:///root1/capture.jpg"
          singleShot TRUE
        }
      }
      geometry Rectangle { size 98 98 }
    }

    # Key sensor to catch left soft key 
    DEF KEY_SENSOR KeySensor { url "E" }

    DEF SCRIPT Script {

        eventIn SFTime pressTime

        field SFNode recordImage USE recordImage
        
        url "
        function pressTime(time) {
          recordImage.startTime = time;
        }
        "
    }
    
    ROUTE KEY_SENSOR.pressTime TO SCRIPT.pressTime 
  ]
}
