TransformPoint

This class provides a list-like interface for accessing and modifying specific coordinate pairs within a raster's geotransform. It maps properties such as origin, scale, and skew to their respective indices, allowing for direct manipulation of spatial parameters through x and y attributes. Changes made to these attributes are automatically synchronized back to the underlying raster object.

Attributes

Attribute	Type	Description
indices	dict = {"origin": (0, 3), "scale": (1, 5), "skew": (2, 4)}	A dictionary mapping transformation property names to their corresponding coordinate index pairs within a GDAL geotransform array.

Constructor

Signature

def TransformPoint(
    raster: object,
    prop: string
) - > null

Parameters

Name	Type	Description
raster	object	The raster object containing the geotransform data.
prop	string	The property key (origin, scale, or skew) used to look up indices in the geotransform.

---

Signature

def TransformPoint(
    raster: Raster,
    prop: string
)

Parameters

Name	Type	Description
raster	Raster	The raster object containing the geotransform array to be accessed and modified.
prop	string	The property key (origin, scale, or skew) used to determine which indices to extract from the geotransform.

---

Methods

---

x()

@classmethod
def x(
    value: float
) - > float

Gets or sets the X-coordinate component of the transform property, automatically updating the underlying raster's geotransform array upon assignment.

Parameters

Name	Type	Description
value	float	The new X-coordinate value to apply to the raster's geotransform at the appropriate index.

Returns

Type	Description
float	The current X-axis value for the specified transform property.

---

y()

@classmethod
def y(
    value: float
) - > float

Gets or sets the Y-coordinate component of the transform property, ensuring changes are persisted back to the raster's geotransform metadata.

Parameters

Name	Type	Description
value	float	The new Y-coordinate value to apply to the raster's geotransform at the appropriate index.

Returns

Type	Description
float	The current Y-axis value for the specified transform property.
