Crop Image
Click the Features | Image | Crop command or the 
button to interactively crop an image. When Crop is enabled, the image extents
can be adjusted by clicking and dragging the sides or corners of the image
limits rectangle or by drawing a new limits rectangle while holding CTRL. The image limits rectangle can be clicked and dragged to move. An image or Base(raster) layer must be selected to enable the Features | Image | Crop command.
The plot window appearance changes when the Crop command is clicked. The areas outside the image limits are shaded. Regions of the plot window within the image limits are displayed normally. The image limits are represented by a blue rectangle with yellow selection handles. Additionally, the Crop command button is highlighted when Crop is active.
Crop Image Tips
The following keyboard and mouse actions control the Crop command mode.
- Click and drag the yellow selection handles to move the map limits.
- Press and hold CTRL, then click and drag to
draw a rectangle to specify the map limits. The cursor will change
to a crosshair
to
indicate draw mode. - Double-click in the plot window or press ENTER to update the map with new map limits and exit Crop mode. Alternatively, right-click in the plot window and click Save to update the image and exit Crop mode.
- Press ESC to exit Crop mode without making any changes to the map. Alternatively, right-click in the plot window and click Cancel to exit Crop mode without making changes.
- Use the mouse wheel or scroll bars to zoom and pan the plot window.
- The Undo command will undo changes to the image limits after you press ENTER or double-click the plot window. However, using the Undo command while Crop is activated will undo actions made prior to activating Crop mode. If you wish to make changes to the image limits while still in Crop mode, click and drag the selection handles or press CTRL and draw a new rectangle.
- The Features | Image | Crop command is disabled for tilted images/maps, rotated images/maps, Base(raster) layers with non-affine warps, and Base(raster) layers that are geotransformed. Crop the image as needed before applying one of these changes.
