Picture is saved rotated

I have the attached stack that takes a picture using the celular camera, without human intervention, and saves it to the device album.
Everything works OK with the device in Portrait mode, but when the mobile is in landscape the picture gets saved rotated by 90 degrees and I haven't been able to fix it, despite the hints I got on related posts ...
This is the code
Code: Select all
on mouseUp
-- set the virtual camera
cameraControlCreate"myFirstCamera"
cameraControlSet "myFirstCamera", "device", "rear"
cameraControlSet "myFirstCamera", "rect", the rect of image "Img1"
cameraControlSet "myFirstCamera", "visible", true
-- take the picture and show it
cameraControlDo "myFirstCamera", "takePicture"
put the result into image "Img1"
cameraControlSet "myFirstCamera", "visible", false
-- save the picture
put the long ID of the last image into tImageID
mobileExportImageToAlbum tImageID
end mouseUp
Looking forward to get help from the gurus...

I have updated my code and now I can rotate the image but I'm getting a
"not a supported format" error when I try to save it to the album.
What am I missing? How to fix it? I'm working on this for several days with no success.
Thanks
Code: Select all
on mouseUp
-- clean previous image
set the visible of img "Img1" to false
set the width of img "Img1" to 300
set the height of img "Img1" to 300
set the locked of img "Img1" to true
-- set the virtual camera
cameraControlCreate"myFirstCamera"
cameraControlSet "myFirstCamera", "device", "rear"
cameraControlSet "myFirstCamera", "rect", the rect of img "Img1"
cameraControlSet "myFirstCamera", "visible", true
-- take the picture and show it
cameraControlDo "myFirstCamera", "takePicture"
put the result into img "Img1"
cameraControlSet "myFirstCamera", "visible", false
set the visible of img "Img1" to true
-- rotate picture according to device orientation
put mobileDeviceOrientation() into theInterfaceOrientation
switch theInterfaceOrientation
case "Landscape Left"
set the angle of img "Img1" to the angle of img "Img1" + 90
break
case "Landscape Right"
set the angle of img "Img1" to the angle of img "Img1" - 90
break
case "Portrait upside down"
set the angle of img "Img1" to the angle of img "Img1" + 180
break
end switch
set the locked of img "Img1" to true
import snapshot from img "Img1"
delete img "Img1"
set the name of last img to "Img1"
-- save the picture
put the long ID of the last img into tImageID
mobileExportImageToAlbum tImageID
put the result into temp
answer temp
end mouseUp

Hi Simon,
two things:
1. "locked" is no valid LC property, please use the correct "lockloc"!
2. Set the paintcompression first to a value that will be accepted by the OS.
Obviously the default value is not compatible with iOS:
Code: Select all
...
end switch
set the lockloc of img "Img1" to true
set the paintcompression to "jpeg"
## or "png"
import snapshot from img "Img1"
...
Hope that helps!
Best
Klaus
