Seven guides, each covering one task: waiting for a screen to settle, recording how it changed over time, keeping it open across calls, comparing two frames, selecting parts of it, bounding the payload, and cropping what changed. They build on the getting-started pages but do not repeat them, so if the coordinate transform is not yet second nature, read that first — several of these depend on it.
If you read three
- 01Replacing sleep()Replaces a fixed delay with three commands: wait for the screen to change, wait for it to stop changing, or run both in sequence.
- 02Persistent sessionsKeeps one connection and a history of raw frames open, and measures what that saves against reconnecting each time.
- 03Regions and overviewsRequests a large overview plus small regions at full detail, instead of one full-resolution frame of everything.
