What device are u using and could u show me the source?

NeoTechni · Jun 13, 2011

Xperia Play

Dim shouldbe As String
shouldbe = "SEPIA"
cam.setColourEffect = Shouldbe
Msgbox("Is: " & cam.getCurrentColourEffect & CRLF & "Supported: " & cam.getSupportedColourEffect, "Should be: '" & shouldbe & "' length=" & shouldbe.Length )

I use my Play too and I have no problems.
Could you post your whole activity project? Or pm it to me.

I can check it better this way.

Hi, Thanks for the library, I downloaded so that I could get the preview in the correct portrait orientation....

Unfortunately I am getting an error saying that I have a java,lang,NullPointerException when using

cameraRear.Initialize(panelPicture, "CameraRear")
cameraRear.OriPortrait()

in Activity_Resume

Please let me know what I am doing wrong!

Cheers

XverhelstX · Jun 20, 2011

What android version are you testing it on?

cooperlegend · Jun 20, 2011

Hi, I am on 2.3.3 SGSII

I just moved this line of code from the Activity_Resume to Sub CameraRear_Ready and it is now working

Was this the likely cause?

Cheers

XverhelstX · Jun 20, 2011

Yes, because the surface is initialized when the camere is ready.
check out the first topic and see an example of it.

Question for library developers:

I'm adding a video recorder to my Advanced Camera Library.
But I receive an error here:

B4X:

m_recorder.setPreviewDisplay(sv.getHolder());

The method setPreviewDisplay(Surface) in the type MediaRecorder is not applicable for the arguments (SurfaceHolder)

Auto fix does this: (Surface) sv.getHolder()

but that gives me an error.

What should be the right surface/ holder for it?

XverhelstX · Jun 22, 2011

Any idea on this?

See above post

agraham · Jun 22, 2011

Maybe

m_recorder.setPreviewDisplay( sv.getHolder().getSurface());

camara issues

I have 2 issues with the advanced camara dll.
1) the preview is always sideways
2) I cannot get the setzoom to work.

Hey Library developers,

I seem to be stuck with the library at the moment.

I show with an inputlist all available colour effects that the device supports but at the end, the colour effect is not active.

here is my code

B4X:

Sub mnuList_Click
'Declare the variables.
Dim strColourEffect As String
Dim strSelectedItem As String
Dim arrayColourEffects() As String
Dim List1 As List

strColourEffect = camera1.SupportedColourEffect 'Gets all the supported effects from the device
strColourEffect = strColourEffect.SubString2(1,strColourEffect.Length-1) ' Removes the '[' and ']' at the beginning and the end of the string
arrayColourEffects = Regex.Split(", ",strColourEffect) ' Splits all the items with ', ' (space included) and puts it in an arrayDim List1 As List
      List1.Initialize
      For i = 0 To arrayColourEffects.Length-1 ' adds the items to the list. (.Length shows how many items there are)
       List1.Add(arrayColourEffects(i)) 'Add the items
      Next
      
      Dim reslist As Int
      reslist = InputList(List1, "Select Colour Effect.", -1) 'show list with the items.
      For i = 0 To arrayColourEffects.Length-1 ' works with the items
          If reslist = i Then
         strSelectedItem = list1.Get(i)
         If strSelectedItem.ToUpperCase = "SEPIA" Then
         Msgbox(strSelectedItem,strSelectedItem.Length) 'Displays the item. 
         End If
         camera1.ColourEffect = strSelectedItem.ToUpperCase 'Sets the value. Uppercase it to work with the Advanced Camera Library.
         End If
      Next
End Sub

At the end: camera1.ColourEffect = strSelectedItem.ToUpperCase, doesn't show the colour effect SEPIA even WHEN the msgbox above it displays?

here is the Java code:

B4X:

/**
    * Sets the color effect of a picture. The following effects are: AQUA,
    * BLACKBOARD, MONO, NEGATIVE, NONE, POSTERIZE, SEPIA, SOLARIZE, WHITEBOARD.
    * For example: Camera1.setColourEffect = "SEPIA"
    */
   public void setColourEffect(String Effect) {
      Camera.Parameters params = c.getParameters();
      if (Effect == "AQUA") {
         params.setColorEffect(Camera.Parameters.EFFECT_AQUA);
         c.setParameters(params);
      }
      if (Effect == "BLACKBOARD") {
         params.setColorEffect(Camera.Parameters.EFFECT_BLACKBOARD);
         c.setParameters(params);
      }
      if (Effect == "MONO") {
         params.setColorEffect(Camera.Parameters.EFFECT_MONO);
         c.setParameters(params);
      }
      if (Effect == "NEGATIVE") {
         params.setColorEffect(Camera.Parameters.EFFECT_NEGATIVE);
         c.setParameters(params);
      }
      if (Effect == "NONE") {
         params.setColorEffect(Camera.Parameters.EFFECT_NONE);
         c.setParameters(params);
      }
      if (Effect == "POSTERIZE") {
         params.setColorEffect(Camera.Parameters.EFFECT_POSTERIZE);
         c.setParameters(params);
      }
      if (Effect == "SEPIA") {
         params.setColorEffect(Camera.Parameters.EFFECT_SEPIA);
         c.setParameters(params);
      }
      if (Effect == "SOLARIZE") {
         params.setColorEffect(Camera.Parameters.EFFECT_SOLARIZE);
         c.setParameters(params);
      }
      if (Effect == "WHITEBOARD") {
         params.setColorEffect(Camera.Parameters.EFFECT_WHITEBOARD);
         c.setParameters(params);
      }
      if (Effect == "sepia") {
         params.setColorEffect(Camera.Parameters.EFFECT_SEPIA);
         c.setParameters(params);
      }
   }

It seemed to be that NeoTechni also struggled with this.
Is this string related or something?

Thanks in advance,

XverhelstX

agraham · Jul 17, 2011

You've fallen into a Java trap that I fell into often coming to Java from C#

Effect == "AQUA"

isn't doing what you think. If you had put some logs in your Java code you would have seen that the condition never succeeds because the == is comparing the string instances by their identity and not by their contents. Sometimes == works because the instances are the same object but in this case you are comparing a string generated in the library to a string instance passed in from Basi4android code. You need

Effect.Equals("AQUA")

XverhelstX · Jul 17, 2011

Oh, I see. Thank you very much, Agraham!
it works now!

Flash?

Hi XverhelstX,

i've testet your extending libary

. Unfortunately the flash mode setting will not work. I tried the examples you have postet on a samsung galaxy tab (7'') with 2.2.

Camera1.getSupportedFlashMode gives me: on, off, auto and torch; but Camera1.FlashOn will not work

.

Thanks in advance.

Cableguy · Jul 19, 2011

Wich galaxy??? there are a few models out there, The S, The new S2, the Mini, The Tab... some, like the S, do not have built-in Flash!

Silentsea · Jul 20, 2011

Sry, the tab, see my edited post.

Camera1.getSupportedFlashMode gets the result, thats because I'm wondering.

Flash is working by builtin cam api

.

Another question for me is, how to show the user a waiting animation, for example with the gif lib, but the ui thread is blocked by loading the cam?

Silentsea · Jul 24, 2011

I tried some other features of your lib, still waiting on feedback on the flash question for my samsung galaxy tab.

For Example, setting picture size. Im my scenario the cam supports 0.4Mp, W0.6, W1.5, 2M, W2.4M, 3.2M

I found out that your lib doesn't support the "w" formats. I can only switch by setting picture size to the next full size. 1600 x 960 will not be possible, i have to choose 1600x 1200.

Only to note

.

Hi,
I tried the following code but it does not seem to work for some reason (device: Motorola MB525) - does nothing. MaxZoom is returned as 5, but setting it to any value does nothing at all. Obviously I am doing something wrong ...

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'return true if you want to consume the event
Select KeyCode
Case KeyCodes.KEYCODE_VOLUME_DOWN:
maxZoom = cam.getMaxZoom
If CamZoom < maxZoom Then
CamZoom = CamZoom + 1
cam.setZoom = CamZoom
End If
Return True
Case KeyCodes.KEYCODE_VOLUME_UP:
If CamZoom > 0 Then
CamZoom = CamZoom - 1
cam.setZoom = CamZoom
End If
Return True
End Select
End Sub
