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

+++++ + + + + + +
