zoom_region
Zoom into a specific rectangle of the current screenshot and recapture it at native resolution for a sharp, legible magnified view. Use to read exact coordinates on surfaces without visible marks or to stay focused on one area.
Instructions
Zoom into a rectangle of the CURRENT image (the last screenshot's pixel space) and re-capture it at native resolution — a sharp, legible magnified view. Only that rectangle is captured (not the whole display), so it is also smaller and quicker to take than a full-display shot. Use it to read exact positions on surfaces that expose no marks (canvas/games, custom-rendered views) before clicking, or to stay scoped while working inside one area. Pass x, y, width, height in the current image's pixels (width,height > 0). The returned image becomes the new coordinate space, and clicks afterward map into the zoomed region automatically. marks defaults OFF (read coordinates off the overlaid grid); grid defaults ON. Take a screenshot first so there is an image to zoom into.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| x | Yes | Left edge of the rectangle, in the CURRENT image's pixel space (the last screenshot's coordinates). | |
| y | Yes | Top edge of the rectangle, in the current image's pixel space. | |
| grid | No | Overlay a labeled coordinate grid. Defaults ON for a zoom (coordinate mode); pass grid=false to suppress it. | |
| marks | No | Set-of-Mark numbering. Defaults OFF for a zoom — the zoom is the tool for surfaces that expose no marks, so you read coordinates off the grid. Pass marks=true to also number any actionable elements inside the region. | |
| width | Yes | Width of the rectangle in current-image pixels. Must be > 0. | |
| height | Yes | Height of the rectangle in current-image pixels. Must be > 0. |
