Types and Values

GimpRgnIterator

Description

The GimpRgnIterator functions provide a variety of common ways to traverse a PixelRegion, using a pre-defined function pointer per pixel.

Functions

GimpRgnFunc1 ()

void
(*GimpRgnFunc1) (const guchar *src,
                 gint bpp,
                 gpointer data);

GimpRgnFunc2 ()

void
(*GimpRgnFunc2) (const guchar *src,
                 guchar *dest,
                 gint bpp,
                 gpointer data);

GimpRgnFuncSrc ()

void
(*GimpRgnFuncSrc) (gint x,
                   gint y,
                   const guchar *src,
                   gint bpp,
                   gpointer data);

GimpRgnFuncDest ()

void
(*GimpRgnFuncDest) (gint x,
                    gint y,
                    guchar *dest,
                    gint bpp,
                    gpointer data);

GimpRgnFuncSrcDest ()

void
(*GimpRgnFuncSrcDest) (gint x,
                       gint y,
                       const guchar *src,
                       guchar *dest,
                       gint bpp,
                       gpointer data);

gimp_rgn_iterator_new ()

GimpRgnIterator *
gimp_rgn_iterator_new (GimpDrawable *drawable,
                       GimpRunMode unused);

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

Creates a new GimpRgnIterator for drawable . The GimpRunMode parameter is ignored. Use gimp_rgn_iterator_free() to free this iterator.

Parameters

drawable	a GimpDrawable
unused	ignored

Returns

a newly allocated GimpRgnIterator.

gimp_rgn_iterator_free ()

void
gimp_rgn_iterator_free (GimpRgnIterator *iter);

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

Frees the resources allocated for iter .

Parameters

iter

a GimpRgnIterator

gimp_rgn_iterator_src ()

void
gimp_rgn_iterator_src (GimpRgnIterator *iter,
                       GimpRgnFuncSrc func,
                       gpointer data);

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

gimp_rgn_iterator_dest ()

void
gimp_rgn_iterator_dest (GimpRgnIterator *iter,
                        GimpRgnFuncDest func,
                        gpointer data);

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

gimp_rgn_iterator_src_dest ()

void
gimp_rgn_iterator_src_dest (GimpRgnIterator *iter,
                            GimpRgnFuncSrcDest func,
                            gpointer data);

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

gimp_rgn_iterate1 ()

void
gimp_rgn_iterate1 (GimpDrawable *drawable,
                   GimpRunMode unused,
                   GimpRgnFunc1 func,
                   gpointer data);

gimp_rgn_iterate1 is deprecated and should not be used in newly-written code.

gimp_rgn_iterate2 ()

void
gimp_rgn_iterate2 (GimpDrawable *drawable,
                   GimpRunMode unused,
                   GimpRgnFunc2 func,
                   gpointer data);

gimp_rgn_iterate2 is deprecated and should not be used in newly-written code.
