Description

Functions giving access to toolbox transform tools.

Functions

gimp_flip ()

gint32
gimp_flip (gint32 drawable_ID,
           GimpOrientationType flip_type);

gimp_flip is deprecated and should not be used in newly-written code.

Use gimp_item_transform_flip_simple() instead.

Parameters

drawable_ID	The affected drawable.
flip_type	Type of flip.

Returns

The flipped drawable.

gimp_perspective ()

gint32
gimp_perspective (gint32 drawable_ID,
                  gboolean interpolation,
                  gdouble x0,
                  gdouble y0,
                  gdouble x1,
                  gdouble y1,
                  gdouble x2,
                  gdouble y2,
                  gdouble x3,
                  gdouble y3);

gimp_perspective is deprecated and should not be used in newly-written code.

Use gimp_item_transform_perspective() instead.

Parameters

drawable_ID	The affected drawable.
interpolation	Whether to use interpolation.
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.
x1	The new x coordinate of upper-right corner of original bounding box.
y1	The new y coordinate of upper-right corner of original bounding box.
x2	The new x coordinate of lower-left corner of original bounding box.
y2	The new y coordinate of lower-left corner of original bounding box.
x3	The new x coordinate of lower-right corner of original bounding box.
y3	The new y coordinate of lower-right corner of original bounding box.

Returns

The newly mapped drawable.

gimp_rotate ()

gint32
gimp_rotate (gint32 drawable_ID,
             gboolean interpolation,
             gdouble angle);

gimp_rotate is deprecated and should not be used in newly-written code.

Use gimp_item_transform_rotate() instead.

Parameters

drawable_ID	The affected drawable.
interpolation	Whether to use interpolation.
angle	The angle of rotation (radians).

Returns

The rotated drawable.

gimp_scale ()

gint32
gimp_scale (gint32 drawable_ID,
            gboolean interpolation,
            gdouble x0,
            gdouble y0,
            gdouble x1,
            gdouble y1);

gimp_scale is deprecated and should not be used in newly-written code.

Use gimp_item_transform_scale() instead.

Parameters

drawable_ID	The affected drawable.
interpolation	Whether to use interpolation.
x0	The new x coordinate of the upper-left corner of the scaled region.
y0	The new y coordinate of the upper-left corner of the scaled region.
x1	The new x coordinate of the lower-right corner of the scaled region.
y1	The new y coordinate of the lower-right corner of the scaled region.

Returns

The scaled drawable.

gimp_shear ()

gint32
gimp_shear (gint32 drawable_ID,
            gboolean interpolation,
            GimpOrientationType shear_type,
            gdouble magnitude);

gimp_shear is deprecated and should not be used in newly-written code.

Use gimp_item_transform_shear() instead.

Parameters
