Class FMETexture

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__

Returns: a new object with type S, a subtype of T

Overrides: object.__new__

This routine makes a duplicate of itself.

Returns: FMETexture

Returns a duplicate of the texture

This routine retrieves the border color of this Texture. The color is a vector in r g b color space with values between 0.0 and 1.0. This will return None if it did not have a border color set.

Returns: tuple of floats

The border color, formatted (ddd) (r, g, b).

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.

Returns: tuple of floats or None

The center, formatted (dd) (u, v).

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

Returns: tuple of floats

The offset, formatted (dd) (u, v).

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.

Returns: int

The angle of rotation.

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

Returns: tuple of floats or None

The scaling factors, formatted (dd) (u, v), or None.

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).

Returns: tuple of floats

The shearing factors, formatted (dd) (u, v).

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

Returns: int

The wrapping style associated with the texture.

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.

Returns: list of lists of floats

The texture's tranformation matrix, formatted [[ddd][ddd]].

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.

Returns: list of lists of floats

The texture's tranformation matrix, formatted [[ddd][ddd]].

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

Returns: bool

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

This routine sets the border color of this Texture. The color values should be in r g b color space withvalues between 0.0 and 1.0. The border color is used only if the FME_TextureWrap value is set to FME_TEXTURE_BORDER_FILL. Setting the border color will also set the FME_TextureWrap value to FME_TEXTURE_BORDER_FILL. Setting the any color value to a negative value will remove the color from this Texture and the FME_TextureWrap 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:

• r (float) - The r value of the border color of this Texture.
• g (float) - The g value of the border color of this Texture.
• b (float) - The b value of the border color of this Texture.

Returns: None

This routine sets the center associated with the texture. The default center for a texture is (0,0). The center is only used for shearing and rotation.

Parameters:

• u (float) - The u point of center.
• v (float) - The v point of the center.

Returns: None

This routine sets the offset associated with the texture. The default offset for a texture is (0,0).

Parameters:

• u (float) - The u point of offset.
• v (float) - The v point of the offset.

Returns: None

This routine sets the rotation angle associated with the texture. Rotation is centered according to the Center variable. The angle is stored in degrees CCW from the x-axis, and is by default 0.

Parameters:

• angle (float) - The angle OF the rotation.

Returns: None

This routine sets the scaling factors associated with the texture. The default scaling for a texture is (1,1).

Parameters:

• u (float) - The u scaling factor.
• v (float) - The v scaling factor.

Returns: None

This routine sets the shearing factors associated with the texture. Shearing is centered according to the Center variable. The default shearing for a texture is (0,0).

Parameters:

• u (float) - The u shear factor.
• v (float) - The v shear factor.

Returns: None

This routine sets the wrapping style associated with the texture. The style is stored as a FME_TextureWrap 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.

Parameters:

• wrapStyle (int) - The wrapping style associated with the texture.

Returns: None

This routine sets the texture transformation matrix associated with the texture. The shear, offset, rotation and will be calculated from the matrix so that when rotation, shear, scale and translation are applied in order, it is the equivalent of the input matrix. If the non-translation component of the matrix has a zero determinant or m[0][0] = 0, the matrix will not be used and existing parameters will remain unchanged.

Parameters:

• matrix (list of lists of floats) - The transformation matrix, formatted [[ddd][ddd]].

Returns: None
