Rotating Images - GPS TrackMaker Reference Manual

11.2 Rotating Images

This option is available only in GPS TrackMaker Professional®.
GPS TrackMaker® uses a process of calibration with two stages:
1 – Image rotation to match the angle of the map grid with the program grid.
2 – Image calibration with two points, changing the position, height and width of the image.
Only Raster images are rotated. Vector images like WMF, EMF and icons cannot be rotated. It is possible to rotate
images with hundredth-degree accuracy.
