I have QGIS version 3.4.3 which does not have print composer. I have a series of lines/tracks/boundaries, etc that are in a layer. I am trying to export that layer with a transparent background for installation in a Garmin GPS unit. I have successfully completed all steps with the exception of creating the transparent background.
I have scoured the web, looked through the technique in Print Composer which is not available in this version and tried to no avail at GPS File Depot.
What am I overlooking?
