Return type: tuple[float]
Returns: The border color, formatted (ddd) (r, g, b).

getCenter()

This routine retrieves the center associated with the texture. This will return None if the center is the default center of (0,0). The center is only used for shearing and rotation.

Return type: tuple[float] or None
Returns: The center, formatted (dd) (u, v).

getOffset()

This routine retrieves the offset associated with the texture. This will return None if the offset is the default offset of (0,0).

Return type: tuple[float]
Returns: The offset, formatted (dd) (u, v).

getRotation()

This routine retrieves the rotation angle associated with the texture. The angle is stored in degrees CCW from the x-axis, and is by default 0. Rotation is centered according to the Center variable. This return None if the scaling is the default angle of 0.

Return type: int
Returns: The angle of rotation.

getScaling()

This routine retrieves the scaling factors associated with the texture. This will return None if the scaling is the default scaling of (1,1).

Return type: tuple[float] or None
Returns: The scaling factors, formatted (dd) (u, v), or None.

getShear()

This routine retrieves the shearing factors associated with the texture. Shearing is centered according to the Center variable. This will return None if the shearing is the default shearing of (0,0).

Return type: tuple[float]
Returns: The shearing factors, formatted (dd) (u, v).

getTextureWrap()

This routine retrieves the wrapping style associated with the texture. The style is stored as a Texture Wrap value, and is by default FME_TEXTURE_REPEAT_BOTH, which results in the texture being tiled in both the u and v direction.

Return type: int
Returns: The wrapping style associated with the texture. One of : FME_TEXTURE_BORDER_FILL, FME_TEXTURE_REPEAT_BOTH, FME_TEXTURE_CLAMP_BOTH, :py:obj`FME_TEXTURE_CLAMP_U_REPEAT_V`, FME_TEXTURE_REPEAT_U_CLAMP_V, FME_TEXTURE_MIRROR, FME_TEXTURE_NONE.

getTransformationMatrix()

This routine retrieves the texture transformation matrix associated with the texture, it is a combination of the rotation, scaling, shear and translation factors, applied in that order.

Return type: list[list[float]]
Returns: The texture’s tranformation matrix, formatted [[ddd][ddd]].

getTransformationMatrixReverse()

This routine retrieves the texture transformation matrix associated with the texture in the reverse order and inverse of each operation, that consists of offset, negative shear, 1 / scale, and negative rotation in that order. This matrix can be used to transform the texture coordinates that are associated with this texture.

Return type: list[list[float]]
Returns: The texture’s tranformation matrix, formatted [[ddd][ddd]].

hasNonIdentityTransform()

This routine returns True if any non-default texture transform factors are set. The default texture transform matrix is identity and this returns False.

Return type: bool
Returns: Returns True if any non-default texture transform factors are set, or False otherwise.

setBorderColor(r, g, b)

This routine sets the border color of this Texture. The color values should be in r g b color space with values between 0.0 and 1.0. The border color is used only if the Texture Wrap value is set to FME_TEXTURE_BORDER_FILL. Setting the border color will also set the Texture Wrap value to FME_TEXTURE_BORDER_FILL. Setting the any color value to a negative value will remove the color from this Texture and the Texture Wrap value will be reset to FME_TEXTURE_REPEAT_BOTH. If the underlying raster is single channel, the gray-scale equivalent border color will be calculated.

Parameters

g (float) – The g value of the border color of this Texture.
b (float) – The b value of the border color of this Texture.

Return type

None

setTextureWrap(wrapStyle)

This routine sets the wrapping style associated with the texture. The style is stored as a Texture Wrap value. If the style is set to FME_TEXTURE_BORDER_FILL, the default border color of black (0,0,0), will be set. If the style is set to something other than FME_TEXTURE_BORDER_FILL, the border color will be removed from the texture.
