AdvancedCameraLibrary Update

Updated to ACL 4.6

- Fixed ACL.ACL.base64 bug
- Added reconnect.
- Zoom functions (please test this.)
- More camera light things have been added. (try them out, I only have 1 device to test on.)
- Front camera gingerbread update
- CurrentPictureSizeHeight - CurrentPictureSizeWidth (proper values) ( CurrentPictureSize deprecated)
- SupportedPictureSizeHeight - SupportedPictureSizeWidth - SupportedPictureSize ( proper values)
- rotateBitmap - rotoateBitmap2: be able to rotate a bitmap quickly after taken a picture. (Bitmap parameter of Bytearray param.)
- Record camera functions removed - See Erel's RecordVideoView
- and some more functions

From 4.5:

Thanks to Canalrun, you can now read, and write strings and integers to the camera! With:

"Read Camera Parameter Key" (rCPKey)
"Write Integer Camera Parameter Key" (wiCPKey)
"Write String Camera Parameter Key" (wsCPKey)
"get Parameter String" (ParmStr)
"set parameter String" (ParmStr)

See more info here: http://www.b4x.com/forum/additional...nced-camera-library-v1-00-a-15.html#post71782

Note that I may now within 1-3 weeks completely rewrite the ACL camera again. (For the 3rd time). This is to make programming much easier, better syntaxis, more declarations, e.g (dim face as FaceRecognition, etc) all in the ACL.

If you have some more questions, found bugs, comments, please post them here.

Hello.

First, thanks for your updates.

One question. ¿How can we control camera Brightness?

We have Samsung Galaxy mini for our peoble and this phone does not have flash. We only can "play" with Brightness to make better photos.

Thanks in advance

Hi,

I discovered a big problem with 'TakePicture2'. The size is much bigger than 'TakePicture' and takes a lot longer to process. I use 90 degrees.

After some pictures, I get an out of memory exception when taking portrait pictures and save them with 'TakePicture2'.

In Landscape mode and 'TakePicture', I have no problems and no exceptions.

Any idea?

Greetings,
Sigurd

ToastMessageShow("Kamera konnte nicht geöffnet werden.", True)
End If
End Sub

Advanced Camera, help needed

I have a "main app" with one layout and then I added another layout ("1") for the camera that I grabbed from another camera project.

If I compile and run the camera sample it works and it show up in the Panel1 window. My problem is that I have this code:

result = Msgbox2("Want to take picture and upload?", "Take Picture", "Yes", "", "No",Null)

If result = DialogResponse.Positive Then

Activity.LoadLayout("1")
Camera1.StartPreview
Camera1.FlashAuto()
Panel1.BringToFront

End If

What I want to do is to take a picture if the user answers Yes but the preview in the Panel1 is not showing up and I can't figure out what to do
Any suggestions?

TakePicture2 Not Working

Hi,

First of all - Nice library! Excellent job!

I am having problems using TakePicture2 with ACL 4.6 - It always hangs!

This works:-
B4X: 
camera1.TakePicture

This hangs every time:-
B4X: 
camera1.TakePicture2(90)

The shutter sound is made, but then things hang and the PictureTaken event is never fired.

Hope someone can help!

Kind regards,
BobsYourUncle

Seem to have solved the problem myself.

When you use Camera1.TakePicture2, it raises

B4X: 
Sub Camera1_PictureTaken2 (Data() As Byte)

instead of

B4X: 
Sub Camera1_PictureTaken (Data() As Byte)

Hi XverhelstX

I have no experience with B4android.
But we are going to use it.
I want to create a little app that works like a lamp for a GSM Mobile phone.

Is there a procedure in de Advance camera lib to put on the led of the camera constant ON are OFF.
So we can use this as a lamp.

Dirk

Hi Tomas
Thank you for this library, I just checked it today and found a wide world of opportunities !

First problem - I can't get the front camera on my Asus Transformer (3.2) to show or take pictures. The back cam works.
I tried both ways - but no

rather lost in eclipse with ACL

Hello all,
Hope one of you can help.
Professional programmer by trade, but rather new to eclipse and java (too many years with assembler/C#/Delphi etc). In one of the earlier posts somebody mentioned that he managed to overrided onPreviewFrame.

I am attempting to do the same as would like to get access to the image data as soon as possible in its most raw format, but becoming rather confused.

I attempted with JarPlug on the acl.jar file, with lines like the following:
public void setResolution(int width, int height);
0 getstatic xvs.ACL.ACL.c : android.hardware.Camera [173]
3 invokevirtual android.hardware.Camera.getParameters() : android.hardware.Camera$Parameters [296]
6 astore_3 [params]
7 aload_3 [params]
from the post earlier it felt that the fellow had access to the source.

Would be very greatful if somebody could point me in the right direction to be able to do the override, or access the source.

Which version of eclipse should I be using?
Should I work with JarPlug?
What is the trick of getting to the source, or do I override in a seperate unit, then rebuild this into a new Jar file for use in B4a?
Or do I have this all totally confused, I should go and have a nice cup of tea?

I am after the image data hopefully in RGB format, in some sort of memory dump, rather than it being passed over as a jpeg, or bmp, then having to turn it back to its origional format. If I can access the data with a picture[calculated offset for red component] rather than calling a routiene that poddles off and gets the values slowly, it would also help.

Any ideas?

Regards,
Jonathan/Molando.

Android Camera API - Tutorial

In this example, the camera works perfectly in front Galaxy S. It's simple, apparently, and I think that could be implemented in the library .... if the developer wants to clear. This would cease to be problems by the use of the camera.

Thank you.

Camera1.SupportedPreviewFpsRange

Mar 5 2012

How do you fetch the values from Camera1.SupportedPreviewFpsRange.

This list is different because each element has an integer array of TWO values.
