Hello,

First, get a handle to the canvas bitmap by using the GetCtrlBitmap function:

int bitmap;

GetCtrlBitmap (pnlHandle, PNL_CANVAS, 0, &bitmap);

Then, you can use SaveBitmapToBMPFile, or SaveBitmapToJPEGFile to save the bitmap to a file. Don't forget to discard the bitmap afterwards (DiscardBitmap).
