Flip the specified drawable either vertically or horizontally.

This procedure flips the specified drawable if no selection exists. If a selection exists, the portion of the drawable which lies under the selection is cut from the drawable and made into a floating selection which is then flipped. If auto_center is set to TRUE, the flip is around the selection's center. Otherwise, the coordinate of the axis needs to be specified. The return value is the ID of the flipped drawable. If there was no selection, this will be equal to the drawable ID supplied as input. Otherwise, this will be the newly created and flipped drawable.

`drawable_ID` : | The affected drawable.
`flip_type` : | Type of flip.
`auto_center` : | Whether to automatically position the axis in the selection center.
`axis` : | coord. of flip axis.
`clip_result` : | Whether to clip results.
Returns : | The flipped drawable.

Flip the specified drawable around a given line.

This procedure flips the specified drawable if no selection exists. If a selection exists, the portion of the drawable which lies under the selection is cut from the drawable and made into a floating selection which is then flipped. The axis to flip around is specified by specifying two points from that line. The return value is the ID of the flipped drawable. If there was no selection, this will be equal to the drawable ID supplied as input. Otherwise, this will be the newly created and flipped drawable. The clip results parameter specifies wheter current selection will affect the transform.

`drawable_ID` : | The affected drawable.
`x0` : | horz. coord. of one end of axis.
`y0` : | vert. coord. of one end of axis.
`x1` : | horz. coord. of other end of axis.
`y1` : | vert. coord. of other end of axis.
`transform_direction` : | Direction of transformation.
`interpolation` : | Type of interpolation.
`supersample` : | This parameter is ignored, supersampling is performed based on the interpolation type.
`recursion_level` : | Maximum recursion level used for supersampling (3 is a nice value).
`clip_result` : | Whether to clip results.
Returns : | The flipped drawable.

Perform a possibly non-affine transformation on the specified drawable, with extra parameters.

This procedure performs a possibly non-affine transformation on the specified drawable by allowing the corners of the original bounding box to be arbitrarily remapped to any values. The specified drawable is remapped if no selection exists. However, if a selection exists, the portion of the drawable which lies under the selection is cut from the drawable and made into a floating selection which is then remapped as specified. The return value is the ID of the remapped drawable. If there was no selection, this will be equal to the drawable ID supplied as input. Otherwise, this will be the newly created and remapped drawable. The 4 coordinates specify the new locations of each corner of the original bounding box. By specifying these values, any affine transformation (rotation, scaling, translation) can be affected. Additionally, these values can be specified such that the resulting transformed drawable will appear to have been projected via a perspective transform.

`drawable_ID` : | The affected drawable.
`x0` : | The new x coordinate of upper-left corner of original bounding box.
`y0` : | The new y coordinate of upper-left corner of original bounding box.

Rotate the specified drawable about given coordinates through the specified angle.

This function rotates the specified drawable if no selection exists. If a selection exists, the portion of the drawable which lies under the selection is cut from the drawable and made into a floating selection which is then rotated by the specified amount. The return value is the ID of the rotated drawable. If there was no selection, this will be equal to the drawable ID supplied as input. Otherwise, this will be the newly created and rotated drawable.

Rotate the specified drawable about given coordinates through the specified angle.

This function rotates the specified drawable if no selection exists. If a selection exists, the portion of the drawable which lies under the selection is cut from the drawable and made into a floating selection which is then rotated by the specified amount. The return value is the ID of the rotated drawable. If there was no selection, this will be equal to the drawable ID supplied as input. Otherwise, this will be the newly created and rotated drawable.

`drawable_ID` : | The affected drawable.
`angle` : | The angle of rotation (radians).
`auto_center` : | Whether to automatically rotate around the selection center.
`center_x` : | The hor. coordinate of the center of rotation.
`center_y` : | The vert. coordinate of the center of rotation.
`transform_direction` : | Direction of transformation.
`interpolation` : | Type of interpolation.
`supersample` : | This parameter is ignored, supersampling is performed based on the interpolation type.
`recursion_level` : | Maximum recursion level used for supersampling (3 is a nice value).
`clip_result` : | How to clip results.
Returns : | The rotated drawable.

This procedure transforms the specified drawable if no selection exists. If a selection exists, the portion of the drawable which lies under the selection is cut from the drawable and made into a floating selection which is then transformed. The transformation is done by scaling the image by the x and y scale factors about the point (source_x, source_y), then rotating around the same point, then translating that point to the new position (dest_x, dest_y).

Transform the specified drawable in 2d, with extra parameters.

This procedure is a variant of `gimp_drawable_transform_matrix()` which uses no interpolation/supersampling at all, or default values (depending on the 'interpolate' parameter).

`drawable_ID` : | The affected drawable.
`coeff_0_0` : | coefficient (0,0) of the transformation matrix.
`coeff_0_1` : | coefficient (0,1) of the transformation matrix.
`coeff_0_2` : | coefficient (0,2) of the transformation matrix.
`coeff_1_0` : | coefficient (1,0) of the transformation matrix.
`coeff_1_1` : | coefficient (1,1) of the transformation matrix.
`coeff_1_2` : | coefficient (1,2) of the transformation matrix.
`coeff_2_0` : | coefficient (2,0) of the transformation matrix.
`coeff_2_1` : | coefficient (2,1) of the transformation matrix.
`coeff_2_2` : | coefficient (2,2) of the transformation matrix.
`interpolate` : | Whether to use interpolation and supersampling.
`clip_result` : | How to clip results.
Returns : | The transformed drawable.
