Hi all, I'm a b4a newb so please bare with me. I'm trying to access a photo stored on my ext. sd card then simply rotate it in an imageviewer. Here is my code:
The photo loads up fine in the imageviewer however when I click to rotate, I just get a "unfortunately, the process b4a example has stopped" My device is a Galaxy S3. Can anyone help?
B4X:
Sub Process_Globals
'These global variables will be declared once when the application starts.
'These variables can be accessed from all modules.
Dim IMG1 As Bitmap
Dim IMGPROC As RSImageEffects
End Sub
Sub Globals
'These global variables will be redeclared each time the activity is created.
'These variables can only be accessed from this module.
Dim rot_button As Button
Dim ImageView1 As ImageView
End Sub
Sub Activity_Create(FirstTime As Boolean)
'Do not forget to load the layout file created with the visual designer. For example:
Activity.LoadLayout("caschy_imgprv")
IMG1 = LoadBitmap(Main.img_dir,Main.img_fn)
ImageView1.Gravity = Gravity.NO_GRAVITY
ImageView1.Bitmap = LoadBitmapSample(Main.img_dir,Main.img_fn,640,480)
End Sub
Sub Activity_Resume
End Sub
Sub Activity_Pause (UserClosed As Boolean)
End Sub
Sub Activity_KeyPress (KeyCode As Int) As Boolean 'return true if you want to consume the event
If KeyCode = KeyCodes.KEYCODE_BACK Then
Activity.Finish
Activity.RemoveViewAt(1)
StartActivity(Main)
End If
End Sub
Sub rot_button_Click
ImageView1.Bitmap = IMGPROC.rotate(IMG1,90)
End Sub
The photo loads up fine in the imageviewer however when I click to rotate, I just get a "unfortunately, the process b4a example has stopped" My device is a Galaxy S3. Can anyone help?
