Save file to Bob's desktop as GIF file on macOS:
MBS( "GMImage.WriteToFile"; $BigImageRef; "/Users/Bob/Desktop/test.gif" )
Save file to Bob's desktop as JPG file on Windows:
MBS( "GMImage.WriteToFile"; $BigImageRef; "C:\Data\logo.jpg" )
Convert image to 1 bit TIFF:
# Load from container
$Image = MBS("GMImage.NewFromContainer"; GraphicsMagick::image);
# make black and white with threshold
$Result = MBS("GMImage.Threshold";$Image; 127);
# mark as monochrome image
$Result = MBS("GMImage.SetMonochrome";$Image; 1);
# set type to 1 for black/white
$Result = MBS("GMImage.SetType";$Image; 1);
# set to use TIFF for compression
$Result = MBS("GMImage.SetMagick";$Image; "TIFF");
# set to use CCITT 4 Fax compression
$Result = MBS("GMImage.SetCompressType";$Image; 4);
# and write to a file
$Result = MBS("GMImage.WriteToFile"; $Image; "/tmp/test.tif");
# cleanup
$Error = MBS("GMImage.Release";$Image)
Loads from file and writes to other file:
Set Variable [$img; Value:MBS("GMImage.NewImagesFromFile"; "/Users/cs/Desktop/test.jpg")]
If [MBS("IsError") = 0]
Set Variable [$r; Value:MBS( "GMImage.WriteToFile"; $img; "/Users/cs/Desktop/test.tif" )]
Set Variable [$r; Value:MBS( "GMImage.Release"; $img)]
End If

# New Image
Set Variable [$img; Value:MBS("GMImage.New"; "300x200"; "RGB 1 1 1")]
# Set colors and line width

Set Variable [$r; Value:MBS("GMImage.SetFillColor"; $img; "RGB 0 0 1")]
Set Variable [$r; Value:MBS("GMImage.SetLineWidth"; $img; 5)]
# draw a rectangle
Set Variable [$r; Value:MBS("GMImage.DrawRectangle"; $img; 50; 50; 250; 150)]
# save to test.png on desktop:
Set Variable [$DesktopPath; Value:MBS( "Folders.UserDesktop" )]
Set Variable [$path; Value:MBS( "Path.AddPathComponent"; $DesktopPath; "test.png")]
Set Variable [$r; Value:MBS("GMImage.WriteToFile"; $img; $path)]
# cleanup
Set Variable [$r; Value:MBS("GMImage.Release"; $img)]
