| row | INT | -1 | Row (horizontal) or column (vertical) index to extract; -1 uses the centre row/column (-1-10000) |
| direction | dropdown | horizontal | Profile direction: horizontal (extract a row) or vertical (extract a column) |
| mode | dropdown | overlay | Combination mode: overlay (field_a profile only), mean (average of both), or difference (field_a minus field_b) |
| blend | FLOAT | 0.5 | Opacity of field B in the preview (0 = only A, 1 = only B). Affects the preview image only, not the extracted profile. |
## Interactive preview
The preview shows field A blended with field B and highlights the row or column being sampled. Click or drag on the image to move the line; switch between row and column extraction with the `direction` control.
