I am trying to remove black borders around the edge of a GeoTIFF. The Black border around the GeoTIFF has an RGB value of
(0,0,0). I have tried assigning
0 as a
"No Data" value to the tiff, but QGIS then makes all pixels which contain a
0 such as
"No Data" pixels. This leaves holes in the map.
Is there a way of only classifying a
"No Data" pixel if
0 is found across all 3 RGB bands on a pixel(pure black pixel)?
I am using the latest version of QGIS 3.8 Zanzibar. Here are 2 screenshots to clarify the situation.
