Rotate photo in Android

Hi. I have learned that Androids take pictures using landscape. My app uses portrait layout.
I can deal with taking a picture using landscape, but when I bring it into the app, it displays sideways. I want to rotate it so it looks OK on the app.
I tried looking at revRotatePoly - but it it not for mobile applications.
How do I rotate an image 90 degress on an Android?
Thank you.

sorry - I didn't realize that the simple command rotate worked in android. As usual, I was looking for a more complex solution.

mobile didn't work.
Thank you Klaus - as usual, you are right on...
except, it needs to be -90
set the angle of image "libImage" to -90
does the trick

Hi cusingerBUSCw5N,

yep, "rotate" is more an "image editing" command, since it is destructive and will really ROTATE the complete image!
Setting the "angle" is non-destructive.

Hey, but you didn't specify a direction!

Thank Klaus for this post. I'm using it but having I resize the image by a scale factor that get to have the image at (a sort of) full screen, when then I rotate it, it keeps the original (big) size. Any advice?
Code: Select all
put (the width of image myImage/the width of this card) into resizeFactor -- (for example 5.4)
set the width of image myImage to the width of image myImage / resizeFactor
set the height of image myImage to the height of image myImage / resizeFactor
if the platform is "android" then
set the angle of image nomeImmagine to -90
end if
set the loc of image myImage to the loc of this card

Hi Mag,
sorry, what is happening with the rect and widht and height of an image
when its angle <> 0 is still a complete mistery to me, so I avoid that

Just replace all the above with:
Code: Select all
if the platform is "android" then
set the angle of image myImage to -90
end if
And just used an image control with the correct sizes and its lockloc set to true
