<format> ::= {BMP | BMP8bit | PNG}
<palette> ::= {COLor | GRAYscale}
The :DISPlay:DATA? query reads screen image data. You can choose 24-bit BMP,
8-bit BMP8bit, or 24-bit PNG formats in color or grayscale.
If no format or palette option is specified, the screen image is returned in BMP,

Example Code
' IMAGE_TRANSFER - In this example, we will query for the image data
' with ":DISPlay:DATA?", read the data, and then save it to a file.
Dim byteData() As Byte
myScope.IO.Timeout = 15000
myScope.WriteString ":DISPlay:DATA? BMP, COLOR"
byteData = myScope.ReadIEEEBlock(BinaryType_UI1)
' Output display data to a file:
strPath = "c:\scope\data\screen.bmp"
' Remove file if it exists.
If Len(Dir(strPath)) Then
Kill strPath
End If
Close #1 ' If #1 is open, close it.
Open strPath For Binary Access Write Lock Write As #1 ' Open file f
or output.
Put #1, , byteData ' Write data.
Close #1 ' Close file.
