Using the Android Document Scanner SDK's cleanup UI screen
Overview
The Scanbot SDK includes a Cleanup Screen to draw over objects and document marks and then remove them from the document. This is particularly useful when users want to remove document artifacts precisely.
Example configuration of the Cleanup UI

Cleanup engine configuration options
Configure the cleanup behavior of the underlying engine through DocumentCleanupConfiguration. In the Ready-to-Use UI, pass it as screens.cleanup.engineConfiguration.
| Property | Type | Default | Description |
|---|---|---|---|
keepText | Boolean | true | If true, the SDK keeps detected text intact while the user erases around it. Text detection runs once up front and can take a moment, so construct the cleanup pipeline asynchronously to keep the UI responsive. |
maxUndoRedoStackSize | Int | 10 | How many undo and redo steps the SDK keeps in memory. Use at least 1 so that reset can always restore the original image. When the limit is reached, the SDK merges the two oldest steps into one. The user can still return to the original image, but with fewer steps in between. |
maxCleanupResolution | Int | 0 | Caps the brushed area the SDK processes in one cleanup step, as width × height in pixels. Larger areas are processed at a lower resolution and scaled back up, which saves memory but can soften the edges near the stroke. 0 means no limit. For example, 1200000 keeps peak memory at about 0.5 GB for a 12 MP image. Prefer cleaning smaller areas over relying on this limit. |
