[hanyelmehy]

i use this code ,but saved image have nothing

Private pnDraw As B4XView
pnDraw.SetLayoutAnimated(0, 0, 0,600,600)
pnDraw.LoadLayout("CartImg1")
'add test to layout'
Dim Out2 As OutputStream
Out2 = File.OpenOutput(WorkPath,"file-name".jpg", False)
pnDraw.Snapshot.WriteToStream(Out2,80,"JPEG")
Out2.Close

Hard to say without a small runnable example.

Try to add Sleep(0) before the snapshot.

i try sleep without success
Note :layout have B4XImageView ,i load layout then load image to B4XImageView ,then try to save

Create a small project and upload

Out2 = File.OpenOutput(WorkPath,"file-name".jpg", False)

You should also get an error, compiling: there is one quotation mark too many (after -name)

-it's a big project it well be difficult to split code
- file-name".jpg just to explain issue
-when change pnDraw from B4XView to Pane Snapshot work ,but it capture only (B4XImageView with images) ,labels not captured
-when test same code on real form ,every thing show correctly ,and when use (RootPane.Snapshot) ,every thing captured
