# Crop / Resize
|
|
|
|
Crop a DATA_FIELD with a draggable rectangle defined by two corners, then optionally resize it. Cropping updates physical extents and offsets; resizing preserves the cropped physical size.
|
|
|
|
## Inputs
|
|
|
|
| Name | Type | Required | Description |
|
|
|------|------|----------|-------------|
|
|
| field | DATA_FIELD | Yes | Input field to crop |
|
|
| corner_a | COORD | No | Locks the top-left corner of the crop box |
|
|
| corner_b | COORD | No | Locks the bottom-right corner of the crop box |
|
|
|
|
## Outputs
|
|
|
|
| Name | Type | Description |
|
|
|------|------|-------------|
|
|
| field | DATA_FIELD | Cropped (and optionally resampled) field |
|
|
|
|
## Controls
|
|
|
|
| Name | Type | Default | Description |
|
|
|------|------|---------|-------------|
|
|
| target_width | INT | 0 | Output pixel width after resampling (0 = keep cropped width) |
|
|
| target_height | INT | 0 | Output pixel height after resampling (0 = keep cropped height) |
|
|
| interpolation | dropdown | bilinear | Resampling interpolation: bilinear, nearest, or bicubic |
|
|
|
|
## Notes
|
|
|
|
- The crop region must have non-zero width and height; an error is raised otherwise.
|
|
- If only one of target_width or target_height is set, the other dimension is computed to preserve aspect ratio.
|
|
- Physical extents are scaled proportionally when resampling.
