Crop command (Image menu)

Use this command to crop the current image. The Panorama Factory displays a cropping rectangle with a horizon line superimposed on the current image.

	Indicates that the cursor is over one of the vertical sides of the cropping rectangle. Dragging changes the width of the rectangle without affecting its height or orientation.
	Indicates that the cursor is over the top or bottom or the horizon line of the cropping orientation. Dragging the top or bottom changes the height of the rectangle without affecting its width or orientation. Dragging the horizon line repositions it without affecting the rectangle’s size or orientation.
	Indicates that the cursor is over one of the corners of the cropping rectangle. Dragging changes the width and height of the rectangle without affecting its orientation.
	Indicates that the cursor is over the intersection of the horizon line with the left or right side of the cropping rectangle. Dragging repositions the intersection point and also changes the width and orientation of the cropping rectangle.
	Indicates that clicking will delete the cropping rectangle. To get this cursor, you have to hold the CTRL key and position the cursor over one of the sides, one of the corners or the horizon line.
	Indicates that the cursor is not over any part of the cropping rectangle. Dragging draws a new cropping rectangle. This cursor appears only when there is no cropping rectangle present. If you have a cropping rectangle, you must delete it in order to get this cursor.

The cropping rectangle is used to simultaneously crop and rotate the image. You use the horizon line to set the rotation. You drag and rotate the horizon line until it is parallel to the horizon in your image. If you are making a 360 degree panorama it’s even easier—you just drag the lefthand and righthand horizon line intersections onto the same feature at the left and right sides of the image. Once you have the horizon line parallel to the image’s horizon, you stretch the four sides of the cropping rectangle to enclose the portion of the image that you want to keep.

When you have the cropping rectangle where you want it, use the Image Approve command to generate the cropped image. The cropped image is added to the end of the computed thumbnails list. If you want to change the cropping rectangle later, select the cropped image and use the Image Show source command to redisplay the cropping rectangle.
