# Image Stitch
|
|
|
|
Combine two overlapping scans into a single image. Uses cross-correlation to align the images and blends the overlap region. Equivalent to Gwyddion's merge.c / stitch.c modules.
|
|
|
|
## Inputs
|
|
|
|
| Name | Type | Required | Description |
|
|
|------|------|----------|-------------|
|
|
| field_a | DATA_FIELD | Yes | First (reference) field |
|
|
| field_b | DATA_FIELD | Yes | Second field to stitch onto field_a |
|
|
|
|
## Outputs
|
|
|
|
| Name | Type | Description |
|
|
|------|------|-------------|
|
|
| stitched | DATA_FIELD | Combined field |
|
|
|
|
## Controls
|
|
|
|
| Name | Type | Default | Description |
|
|
|------|------|---------|-------------|
|
|
| direction | dropdown | auto | How field_b is positioned relative to field_a: right, below, or auto (determined by cross-correlation) |
|
|
| blend | dropdown | linear | Overlap blending: linear (smooth transition) or none (hard cut) |
|
|
|
|
## Notes
|
|
|
|
- Auto direction uses cross-correlation to determine whether field_b is to the right or below field_a.
|
|
- Linear blending produces a smooth transition in the overlap region, avoiding visible seams.
|
|
- Both fields should have the same pixel size (dx, dy) for correct physical dimensions in the output.
|
|
- The output field's physical dimensions are updated to reflect the combined area.
