Open Traffic program-click right into drawing-

-change transparency-Select to black-finish

thank you magd

Message in Traffic when you do this:
'transparent color from opposite corner only possible with TVL files Continue?'
When you click Yes a windows opens, to search for the tvl file.

Transparent to Black files must have the BMP. Format
