"FengShui Transparent Compass" is a tool used for measuring orientation on "maps" and "house architectural floor plans." It provides various polar scales, acting as a transparent compass overlaid on a map or image to facilitate orientation measurement and Feng Shui assessment. Provides more than a dozen compass face options. File Management: (Offers file management with thumbnail previews to easily manage all manipulated files) Supports iCloud Cloud Backup and Data Recovery functions (backing up overlay files and settings). Base Maps:  ●Map: Capture maps to use as base maps, with three display modes: Normal, Satellite, and Hybrid. You can also search for addresses (which can be recorded in the current file).  ●Album: Choose images from the device's photo album as base maps.  ●Camera: Use the camera to take photos and use them as base maps.  ●Edit: Crop and rotate base maps. Central Positioning:  ●Purpose: Measure the central position of a specific area on the base map.  ●Styles: Offers seven styles – 2x2, 3x3, 4x4, 5x5, 6x6, 7x7, and Polygon.  ●Fixed Display: Check to keep it displayed continuously and save the state.  ●Operating Steps:   ●Place a polygon and align it with a specific area on the base map.   ●Adjust its size and rotation freely.   ●Tap "Place Polar Scale in Center" to position the polar scale at the center. Note that the rotation angle does not affect the polar scale; the primary purpose is alignment with the base map.  ●Polygon Operation:   ●Drag the red dot to align with the measured area.   ●Tap on a line and drag to add a new point. The blue central dot represents the center of the polygon. Polar Scale:  ●Adjust the angles of the "Polar Scale" and "Crosshair" to align with the orientation of the buildings on the base map.  ●Input angles or use sliders to adjust them.  ●Sync Option:   ●Map as the base map: Uncheck synchronization since the map's orientation is fixed at True North, and you only need to adjust the crosshair orientation.   ●Photo as the base map: Synchronization is automatically checked. If the bottom is "Zuo Shan" and the top is "Xiang Shan," synchronization is adjusted accordingly. (Exceptional cases can uncheck synchronization and adjust separately.)  ●Transparency: Adjust the transparency of the polar scale based on the base map's color.  ●Crosshair: Show or hide the crosshair.  ●Gesture Controls:   ●Tap the polar scale once to reveal buttons at its four corners.    ●Hold the top-left and top-right corners to resize and rotate the polar scale.    ●Hold the bottom-left and bottom-right corners to resize the polar scale (use this if you don't want to change the angle).   ●Two fingers to zoom in and out.  ●You can also share the overlay via Google Cloud Print, WeChat, Line, Messenger, and other platforms depending on device sharing options. Double Star Explanation:  ●When using a 1-9 Yun Xuan Kong Flying Star chart, tapping on a palace will display a double star explanation (editable in settings). Auxiliary Lines:  ●Offers three auxiliary line colors: Red, Blue, Green.  ●Tap the bottom function to display a specific auxiliary line, or uncheck it to hide.  ●Methods to adjust auxiliary line angles:   1.From within the polar scale, drag to rotate the auxiliary lines.   2.Use the angle buttons below to input angles.   3.Use the slider below to adjust angles. Magnetic Declination:  ●Specify latitude, longitude, and date to obtain magnetic declination from the NOAA website, or manually input magnetic declination.  ●You can apply magnetic declination to correct the orientation of the base map. Preferences Settings... ● This tool is only an auxiliary tool for Feng Shui identification, and the user needs to have relevant knowledge of Feng Shui. ● Operation interface: Traditional Chinese, Simplified Chinese, Japanese, English. ● It also supports tablet large screen display in any direction.
