Hard to say without a small runnable example.

Try to add Sleep(0) before the snapshot.

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
