堪輿透明羅盤 app for iPhone and iPad

"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 devices 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 four styles – Crosshair, Nine Palaces Grid, 7x7 Grid, 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 maps 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 maps 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 dont 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.
