The Edit Window

Edit Windows form the main work area within ReefMaster and are where individual assets, such as Tracks, Map Projects and Sidescan Mosaics can be viewed and edited.

All edit windows consist of a window with a map view, where the geographic components of the selected asset are display:

Each open edit window has its own tab (1). Switch between different assets for editing by clicking on the the required assets' tab, to activate that asset window. Edit windows can also be rearranged within the workspace, so that more than one asset can be viewed at the same time. See Application Layout for more information.

The main area (3) within an edit window contains a graphical view of the asset(s) to be edited and a pop-out mouse mode toolbar (2).

·Zoom by using the mouse wheel, + or - keys, or one the zoom tool in the View menu bar.

·Panned by using the mouse in Pan mode, the arrow keys or by using the middle mouse button whilst in any mouse mode.

·To fit the current view to the assets displayed, use the Fit Window command in the View menu bar, or double click with the left mouse button anywhere within the main work area.

·Individual edit windows can be made full-screen by using the F11 button. Press F11 again to exit full-screen mode.

All asset edit windows, with the exception the the Global View and Background Images, have properties that can be edited in the Edit Panel. The edit panel shows the properties for whichever edit view is active, and can be opened by clicking the Edit tab at the right of the screen.

The View Menu Bar

The View menu bar is available for all edit windows and contains controls for the display of the active edit window:

1. Mouse Modes

The mouse mode selector is used to select what operation the left mouse button performs within the main editing area. The mouse cursor within the edit area changes to reflect the selected mode, and the selected mode is highlighted within the toolbar; in the example above, Select mode is active.

·The mouse wheel is always used for zooming; push the wheel forwards to zoom in, and backwards to zoom out.

·The right mouse button is used to activate a Context Menu. If the mouse pointer is over an asset, then an asset specific menu is shown, otherwise the screen-level context menu is shown.

·The view can be panned by using the middle mouse button, regardless of the currently selected mouse mode.

A mouse mode selector is also available as a pop-up in the top-left corner of the edit window, and within the right-button menu of the edit window.

Select

Select is the default mouse mode. In select mode, a single click of the left mouse button selects an item in the display, if the item is selectable. If an item can be edited, double-clicking the left mouse button on the item will open that item for editing.

Zoom

A Zoom Box is used to zoom the edit area to fit a rectangular area drawn by holding the left mouse button down and dragging the mouse.

Pan

In Pan mode the entire contents of the edit area can be "grabbed" and panned. Note that the view can also be panned by using the middle mouse button, regardless of the currently selected mouse mode.

Region Select

The Region Select tool is used to select multiple items within the edit area. All items are selected within a rectangular region defined by holding the left mouse button down and dragging the mouse. Operations that can be performed on the selected assets vary according to the asset type(s) selected, and the type of edit window in use.

Drop Waypoint

Clicking the left mouse button when in this mode drops a Waypoint at the point underneath the tip of the mouse cursor. The Edit Waypoint window is displayed, where further information, such as the waypoint name, can be entered.

Measure Distance

Measure a distance between two points. Click and hold the left mouse at the start point and move the mouse pointer to the second point; the ruler updates as the mouse is moved.

Notes on measuring distances

The measure tool measures the shortest distance between two points on a constant bearing (along a rhumb line). This is not the same as the shortest geographical distance (great circle), although the difference is not significant at the short distances typically required for measuring maps, waypoint distances etc. Another effect of this behaviour is that distances shown on the ruler tool may appear to reduce as the ruler length is increased to over half the circumference of the earth. This is because the calculated distance is the shortest distance between the two points, and becomes shorter going the other way around the earth.

2. Zoom

Fit Window

Zoom the display area to fit the geographical extent of the asset being edited. The fit window function can also be activated by double-clicking anywhere within the map view.

Zoom in/out

Zoom in and out by a preset amount by clicking the zoom buttons. Zooming can also be achieved by using the mouse wheel or the + and - keyboard keys.

3. Background

Grid Lines

Show or hide the map grid lines, and vary the frequency of the lines. A slider is shown when this button is pressed. Moving the slider to the right increases the density of grid lines shown on the map. Moving the slider all the way to the left removes the grid lines entirely.

Show Background Map

Show or hide the background map using the Show Background Map toggle button. The map which is shown is selected in Global Settings.

Background Images

Any background images that have been imported into the workspace can be displayed as backgrounds in an edit window. The visibility of individual images can be toggled in the background images drop-down, and the opacity adjusted.

The Context Menu

The screen-level context menu can be activated using the right mouse button whilst the mouse pointer is held over open space in the graphical edit area; i.e., the pointer is not held over an asset. Different asset edit windows have different options available in their context menus, with some operations common to most asset types.

Keyboard Shortcuts

·Edit windows can be zoomed by using the + or - minus keys. Hold down the CTRL key in conjunction with the + or - key to increase the zoom amount.

·Edit windows can be panned by using the arrow keys. Hold down the CTRL key in conjunction with an arrow key to increase the speed of the pan.
