Hey, thanks a lot for the article. I am trying to rasterize a layer that I imported into a psd document. I posted the question on stack overflow but didn't get any reply. from photoshop import Session with Session("C:/Users/Admin/Documents/images/edit_wall.psd", action="open") as ps: doc = ps.active_document desc = ps.ActionDescriptor desc.putPath(ps.app.charIDToTypeID("null"), "C:/CG_CONTENT/wall_height.exr") event_id = ps.app.charIDToTypeID("Plc ") # `Plc` need one space in here. ps.app.executeAction(ps.app.charIDToTypeID("Plc "), desc) currentLayer = doc.activeLayer doc.rasterize(currentLayer) Can you point me in the right direction? Thanks.
