static void | helmert (const QVector< QgsPointXY > &sourceCoordinates, const QVector< QgsPointXY > &destinationCoordinates, QgsPointXY &origin, double &pixelSize, double &rotation) |
Transforms the point at origin in-place, using a helmert transformation calculated from the list of source and destination Ground Control Points (GCPs). | |
static void | linear (const QVector< QgsPointXY > &sourceCoordinates, const QVector< QgsPointXY > &destinationCoordinates, QgsPointXY &origin, double &pixelXSize, double &pixelYSize) |
Transforms the point at origin in-place, using a linear transformation calculated from the list of source and destination Ground Control Points (GCPs). | |
static void | projective (const QVector< QgsPointXY > &sourceCoordinates, const QVector< QgsPointXY > &destinationCoordinates, double H[9]) |
