Inherited Members

Remarks

A world file is an attribute file that is associated with a corresponding image file. Typically, the world file consists of 6 lines of numbers.

Constructors

WorldFile()

This is the default constructor for the WorldFile class.

public WorldFile()

Remarks

None

WorldFile(double, double, double, double, double, double)

This is a constructor that passes 6 attributes in double associated with the corresponding image file.

public WorldFile(double horizontalResolution, double rotationRow, double rotationColumn, double verticalResolution, double upperLeftX, double upperLeftY)

Parameters

horizontalResolution double

This parameter specifies the size of pixels in the x direction.

rotationRow double

This parameter specifies the rotation term for row.

rotationColumn double

This parameter specifes the rotation term for column.

verticalResolution double

This parameter specifies the size of pixels in the y direction.

upperLeftX double

This parameter represents the x coordinate of the center of the upper-leftmost pixel in map units.

upperLeftY double

This parameter represents the y coordinate of the center of the upper-leftmost pixel in map units.

WorldFile(float, float, float, float, float, float)

This is a constructor that passes 6 attributes in float associated with the corresponding image file.

public WorldFile(float horizontalResolution, float rotationRow, float rotationColumn, float verticalResolution, float upperLeftX, float upperLeftY)

Parameters

horizontalResolution float

This parameter specifies the size of pixels in the x direction.

rotationRow float
