It is not possible with this lib, sorry...

If you find a better library (java) i can try to do a wrap for it.

Hi Don,
I am using your crop library (which works great) but I am combining it with CameraEX.
I want to take a photo, save it to a file, then allow the user to crop it and save it.
when I combine the two:

• CameraEx takes the photo and saves it
• I then startactivity(crop), which is your demo
• when the LoadLayout("Layout1") executes, I get

** Activity (main) Create, isFirst = true **
automode false
** Activity (main) Resume **
Continuous focus mode is not available
[Height=480, IsInitialized=false, Width=640
]
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
** Activity (crop) Create, isFirst = true **
Error occurred on line: 19 (Crop)

Line 19 is:

Sub Activity_Create(FirstTime As Boolean)
 LINE 19 >>---->   Activity.LoadLayout("layout1")
                            
End Sub

any ideas what is in the Layout1 (your original layout) that might be causing this?
Thanks Rusty

 

[DonManfred]

My guess is that the camera is still in use by your camera ex class in first activity

 

[Rusty]

Sub btnCrop_Click
    camEx.CloseNow
    camEx.Release
    StartActivity(Crop)
End Sub

This is the code calling the startactivity(crop)

 

[DonManfred]

Try to move the StartActivity to a new Sub And Use callsubplus to start the Sub in 500ms

 

[Rusty]

I moved it to a new sub and called callsubplus and waited 1000ms

Sub btnCrop_Click
    camEx.CloseNow
    camEx.Release
    Dim callPlus As CallSubPlus
    callPlus.Initialize
    callPlus.CallSubPlus(Me, StartAct, 1000)
End Sub

Sub StartAct
    StartActivity(Crop)
End Sub

Still no happiness.
I have even tried removing the civ from the layout1.bal file and adding it in code, but it dies on that too...
Thanks ,

 

[DonManfred]

hmm, ok. I´ll investigate

 

[Rusty]

I looked at the Module attributes and I must have overlaid the #AdditionalRes: ..\resources
I added that back and now it seems to load
Sorry to waste your time
Thanks for the help.

Hi Don,
Your class works great
Is there a way to move the crop rectangle to a specific x, y coordinate (as center)?
Thanks
Rusty

 

[DonManfred]

Unfortunatly no.

 

[Rusty]

Thanks Don!
Can the background image be moved behind the rectangle to center it appropriately?

 

[DonManfred]

again no. Sorry, there is no method in the library to do...
