Offset labels

Have you explored the MapnikRasterizer?

I haven't used it much, but believe this should be able to do what you’re after

yes, but I don’t want my export to be a raster. I need all the text to be selectable, therefore I need my data to be vector.

Hello ​@fazacasbianca 

I’m not sure if there’s a specific attribute you can set, but you can use a spatial join between the text and its associated line using a NeighborFinder. Then, use the distance attribute created by the NeighborFinder in an Offsetter to position the label correctly.

For pipes, this should be easy (one label per line).For manholes, since multiple lines may be connected, it’s best to restrict the spatial join to horizontal lines. Because I suppose that on the printed plan, all manhole labels are oriented horizontally.

Otherwise the Labeller transformer is also a great alternative to the TextAdder.
