Trimming corners are used to trim imported pictures that are overscanned to show the edges of a print or negative frame. Once placed on the image, trimming corners can be moved to reposition them:
Rectangles are used for trimming with fixed-size rectangles and when previewing tentative image changes. Ordinary rectangles can usually be resized by moving their edges, but cannot be moved arbitrarily:
Please read about the Color tool (Tools menu), the Sharpen command (New image menu), and the section “Adjusting exposure matching and brightness falloff” in Chapter 6, “Correcting stitching problems” for examples of preview rectangles.
Fine tuning tiles are used to fine-tune image alignment by making local adjustments in an overlap region. A line radiating from the center of each tile shows the direction and magnitude of the adjustment. Fine tuning tiles can be resized by moving their edges and the direction and magnitude of the adjustment can be changed:
The Crop command (New image menu) displays a cropping rectangle. Cropping rectangles show a center horizon line which may be rotated to follow the average rise or fall of a panorama. Cropping rectangles can be resized by by moving their edges, but cannot be moved arbitrarily:
Spots, movable circles, movable rectangles and polygons are used to indicate hotspots for web page hyper linking. Movable circles and rectangles are distinguished from ordinary circles and rectangles by central crosses. Spots, movable circles, movable rectangles and polygons can be moved arbitrarily. Movable circles and movable rectangles can be resized. Polygons can be edited to change their shape:
Irregular outlines show the blending regions between each image and the next in a stitched panorama. Please refer to “Classic step 2 – Stitch the images into a panorama” in Chapter 4, “Using the Classic interface, step by step” for examples of irregular outlines.
A warping grid is used to adjust the panoramic image warping to correct a curved horizon or slanted vertical lines in the stitched image. Please read “Wizard step 7/9 – Preview at low resolution” in Chapter 3, “Using the Stitching Wizard to make a panorama” for examples of the warping grid.
