Android Question Cameraexclass: Distortion problem

[grafsoft]

Hi,

this is my code

#Region  Activity Attributes
   #FullScreen: false
   #IncludeTitle: true
#End Region

Private Sub InitializeCamera
   Try
   camEx.Initialize(Panel1, frontCamera, Me, "Camera1")
   frontCamera = camEx.Front
   Catch
     Dim s As String
     s="Camera Resume " & LastException.Message
     Log (s)
     Main.prot.Add (s)
   End Try
End Sub

Sub camera1_Ready (Success As Boolean)
   Try
   If Success Then
     camEx.SetJpegQuality(Settings.jpgquality)
     
     camEx.CommitParameters
     ' camEx.SetPictureSize (Panel1.Width,Panel1.Height)
     camEx.StartPreview
     Log(camEx.GetPreviewSize)
     camerasetbuttons
     
     
     
   Else
     ToastMessageShow("Die Kamera funktioniert nicht.", True)
   End If
   Catch
     Dim s As String
     s="Camera ready " & LastException.Message
     Log (s)
     Main.prot.Add (s)
   End Try
End Sub

This produces no distortion.

When I reverse the variables for fullscreen and includetitle to true and false, the picture becomes distsorted, everything is too wide. Setpicturesize does not help.

What am I doing wrong?

Thank you

Peter

The preview images are distorted? What is the size of the preview panel?

 

[grafsoft]

The size of the panel is 897*720. The preview is distorted, everything looks higher. The picture taken has the right proportions.

Since I need some buttons, the panel is 75%x to 100%y. Should I take care that the panel has the same proportions of the entire screen?

 

[grafsoft]

Stupid me, that was the answer. Thank you!

 

[grafsoft]

Sorry, still not solved.

The photo is OK, the preview is distorted. I need to have a preview with other width/height ratio than the screen.

 

[grafsoft]

Maybe bacvause of this:

camEx.SetPictureSize (Panel1.Width,Panel1.Height)

Why this?

 

[grafsoft]

Here https://www.b4x.com/android/forum/t...ibrary-functionality.23801/page-7#post-172191 a method called setpreviewsize is mentioned. But it does not work.

 

[Erel]

Both methods are part of Android SDK: http://developer.android.com/reference/android/hardware/Camera.Parameters.html#setPictureSize(int, int)

Which device are you using?
Can you upload your project?

 

[grafsoft]

Thank you very much for your help! I really need it.

When you start the app, you start the activity "Kamera". I need the right margin, because I need to put the buttons somewhere.

You see it is slightly distorted here.

When you take the picture, you come to another activity, "Draw", where you can draw on the picture (not in this app, I wanted to keep it simple). You see it is distorted the other way round.

You see it best when you make a picture of a round object.

Thanks

Peter

Have you solved the NoSuchMethodException error?

 

[grafsoft]

No. If you uncomment line 136 in "Kamera", it will compile, but then I get the error.

 

[Erel]

Why shouldn't it be distorted? You are not checking the bitmap width and height. How do you know that the ratio is the same ratio as the ratio of pnlDrawing?

 

[grafsoft]

It is 90%x * 100%y in both cases.

I know I must make a mistake somewhere, but I do not find it.

 

[Erel]

You need to check the bitmap width and height and set the panel to be the same size (or ratio) as the bitmap size.

 

[grafsoft]

>ou mean

cvsBackground.DrawBitmap(LoadBitmap(Main.outdir, Main.thepic), Null, rectPanels)

?

I can check that. But in the module Kamera, where the image is saved, ther is not bitmap, and the image is saved distorted. The bigger problem lies here.

 

[Erel]

The camera provides you the bitmap (its data). Its size has no relation to the preview panel size. You need to load the bitmap and check its size.

 

[grafsoft]

Thank you, that solved the distortion problem!
