Exporting Geotiff loaded data only.

DafaDafa Global Mapper UserPosts: 2

I am trying to export a geotiff image loaded data only. 
My source data is a Tif file with TFW file. I use a prj file to load it into global mapper. Than I configure the data to a Geo/WGS 84 file to export it and use for some mapping software where several similar maps need to be glued together. The result is seen In Image 1
I want to get rid of the yellow band around the map. I assume the problem is the exporting setting but I don't find the solution

Best regards

    Try putting a check next to Make Background (Void) Pixels Transparent on the GeoTIFF Export Options screen.

    Hi, i am having the same issue.  ie I click transparent, however background is in black.  The generated geotiff areas are correct, just the background is black for each tile.  sample screen dump below overlayed on GoogleEarthPro.
