Declaration [src]
GimpItem*
gimp_item_transform_2d (
GimpItem* item,
gdouble source_x,
gdouble source_y,
gdouble scale_x,
gdouble scale_y,
gdouble angle,
gdouble dest_x,
gdouble dest_y
)
Description [src]
Transform the specified item in 2d.
This procedure transforms the specified item.
The transformation is done by scaling 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).
If a selection exists and the item is a drawable, 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 as specified. The return value is the ID of the transformed floating selection.
If there is no selection or the item is not a drawable, the entire item will be transformed according to the specified parameters. The return value will be equal to the item ID supplied as input.
This procedure is affected by the following context setters: gimp_context_set_interpolation(), gimp_context_set_transform_direction(), gimp_context_set_transform_resize().
Available since: 2.8
Parameters
source_x-
Type:
gdoubleX coordinate of the transformation center.
source_y-
Type:
gdoubleY coordinate of the transformation center.
scale_x-
Type:
gdoubleAmount to scale in x direction.
scale_y-
Type:
gdoubleAmount to scale in y direction.
angle-
Type:
gdoubleThe angle of rotation (radians).
dest_x-
Type:
gdoubleX coordinate of where the center goes.
dest_y-
Type:
gdoubleY coordinate of where the center goes.
Return value
Type: GimpItem
The transformed item.
