Save image to file

[macerau]

Hi Erel,
From what I read a lot in the documentation and realized all looking for an answer that I'm sure is very simple.
a routine that writes image to a file from ImageView.
I have no doubts that this can help many users
Please see if you can make this routine

....
SavePhoto (Photo.bitmap,"MyPhoto.png")

....


Sub SavePhoto (Pt As Bitmap,NewFile As String)
?
?
End Sub

See Bitmap.WriteToStream documentation:
Basic4android Search: bitmap.writetostream

....
SavePhoto (Photo.bitmap,"MyPhoto.png")

....


Sub SavePhoto (Pt As Bitmap,NewFile As String)
 Dim Out As OutputStream 
 Out = File.OpenOutput(File.DirRootExternal, NewFile, False)
 Pt.WriteToStream(out, 100, "PNG") 
 Out.Close
End Sub

Very Well This work!
had tried this routine several times, and it did not work because I was used File.DirAssets.
It is not possible to write in File.DirAssets?

My satisfaction of both the program and the support is 10! Keep it up!

No it is not, File.dirAssets is READ ONLY.

File.dir assets Is a pretend folder that really just unzips and let's you read files you include. file.dirinternal is always there' its phone memory. Direxternal may or may not exist. Eg, sdcard.
