## Description

Functions to manipulate drawables.

## Details

### GimpDrawable

    typedef struct {
      gint32    drawable_id;   /* drawable ID */
      guint     width;         /* width of drawble */
      guint     height;        /* height of drawble */
      guint     bpp;           /* bytes per pixel of drawable */
      guint     ntile_rows;    /* # of tile rows */
      guint     ntile_cols;    /* # of tile columns */
      GimpTile *tiles;         /* the normal tiles */
      GimpTile *shadow_tiles;  /* the shadow tiles */
    } GimpDrawable;

### gimp_drawable_get ()

    GimpDrawable *      gimp_drawable_get                   (gint32 drawable_ID);

This function creates a GimpDrawable structure for the core drawable identified by `drawable_ID`. The returned structure contains some basic information about the drawable and can also hold tile data for transfer to and from the core.

Note that the name of this function is somewhat misleading, because it suggests that it simply returns a handle. This is not the case: if the function is called multiple times, it creates separate tile lists each time, which will usually produce undesired results.

When a plug-in has finished working with a drawable, before exiting it should call `gimp_drawable_detach()` to make sure that all tile data is transferred back to the core.

`drawable_ID` : | the ID of the drawable
Returns : | a new GimpDrawable wrapper

### gimp_drawable_detach ()

    void                gimp_drawable_detach                (GimpDrawable *drawable);

This function is called when a plug-in is finished working with a drawable. It forces all tile data held in the tile list of the GimpDrawable to be transferred to the core, and then frees all associated memory. You must not access the `drawable` after having called `gimp_drawable_detach()`.

`drawable` : | The GimpDrawable to detach from the core

### gimp_drawable_flush ()

    void                gimp_drawable_flush                 (GimpDrawable *drawable);

This function causes all tile data in the tile list of `drawable` to be transferred to the core. It is usually called in situations where a plug-in acts on a drawable, and then needs to read the results of its actions. Data transferred back from the core will not generally be valid unless `gimp_drawable_flush()` has been called beforehand.

`drawable` : | The GimpDrawable whose tile data is to be transferred to the core.

### gimp_drawable_delete ()

    gboolean            gimp_drawable_delete                (gint32 drawable_ID);

### Warning

`gimp_drawable_delete` is deprecated and should not be used in newly-written code. Use `gimp_item_delete()` instead.

`drawable_ID` : | The drawable to delete.
Returns : | TRUE on success.

### gimp_drawable_is_valid ()

    gboolean            gimp_drawable_is_valid              (gint32 drawable_ID);

### Warning

`gimp_drawable_is_valid` is deprecated and should not be used in newly-written code. Use `gimp_item_is_valid()` instead.

`drawable_ID` : | The drawable to check.
Returns : | Whether the drawable ID is valid.

Since GIMP 2.4

### gimp_drawable_get_name ()

    gchar *             gimp_drawable_get_name              (gint32 drawable_ID);

### Warning

`gimp_drawable_get_name` is deprecated and should not be used in newly-written code. Use `gimp_item_get_name()` instead.

`drawable_ID` : | The drawable.
Returns : | The drawable name.

### gimp_drawable_set_name ()

    gboolean            gimp_drawable_set_name              (gint32 drawable_ID,
                                                             const gchar *name);

### Warning

`gimp_drawable_set_name` is deprecated and should not be used in newly-written code. Use `gimp_item_set_name()` instead.

`drawable_ID` : | The drawable.
`name` : | The new drawable name.
Returns : | TRUE on success.

### gimp_drawable_get_visible ()

    gboolean            gimp_drawable_get_visible           (gint32 drawable_ID);

### Warning

`gimp_drawable_get_visible` is deprecated and should not be used in newly-written code. Use `gimp_item_get_visible()` instead.

`drawable_ID` : | The drawable.
Returns : | The drawable visibility.

### gimp_drawable_set_visible ()

    gboolean            gimp_drawable_set_visible           (gint32 drawable_ID,
                                                             gboolean visible);

### Warning

`gimp_drawable_set_visible` is deprecated and should not be used in newly-written code. Use `gimp_item_set_visible()` instead.

`drawable_ID` : | The drawable.
`visible` : | The new drawable visibility.

Merge the shadow buffer with the specified drawable.

This procedure combines the contents of the drawable's shadow buffer (for temporary processing) with the specified drawable. The 'undo' parameter specifies whether to add an undo step for the operation. Requesting no undo is useful for such applications as 'auto-apply'.

`drawable_ID` : | The drawable.

Returns : | TRUE on success.

### gimp_drawable_free_shadow ()

    gboolean            gimp_drawable_free_shadow           (gint32 drawable_ID);

This procedure is intended as a memory saving device. If any shadow memory has been allocated, it will be freed automatically when the drawable is removed from the image, or when the plug-in procedure which allocated it returns.

`drawable_ID` : | The drawable.
Returns : | TRUE on success.

Fill the drawable with the specified fill mode.

This procedure fills the drawable. If the fill mode is foreground the current foreground color is used. If the fill mode is background, the current background color is used. If the fill type is white, then white is used. Transparent fill only affects layers with an alpha channel, in which case the alpha channel is set to transparent. If the drawable has no alpha channel, it is filled to white. No fill leaves the drawable's contents undefined. This procedure is unlike `gimp_edit_fill()` or the bucket fill tool because it fills regardless of a selection. Its main purpose is to fill a newly created drawable before adding it to the image. This operation cannot be undone.

`drawable_ID` : | The drawable.
`fill_type` : | The type of fill.
Returns : | TRUE on success.

### gimp_drawable_update ()

Update the specified region of the drawable.

This procedure updates the specified region of the drawable. The (x, y) coordinate pair is relative to the drawable's origin, not to the image origin. Therefore, the entire drawable can be updated using (0, 0, width, height).

`drawable_ID` : | The drawable.
`x` : | x coordinate of upper left corner of update region.
`y` : | y coordinate of upper left corner of update region.
`width` : | Width of update region.
`height` : | Height of update region.

Find the bounding box of the current selection in relation to the specified drawable.

This procedure returns whether there is a selection. If there is one, the upper left and lower right-hand corners of its bounding box are returned. These coordinates are specified relative to the drawable's origin, and bounded by the drawable's extents. Please note that the pixel specified by the lower right-hand coordinate of the bounding box is not part of the selection. The selection ends at the upper left corner of this pixel. This means the width of the selection can be calculated as (x2 - x1), its height as (y2 - y1). Note that the returned boolean does NOT correspond with the returned region being empty or not, it always returns whether the selection is non_empty. See `gimp_drawable_mask_intersect()` for a boolean return value which is more useful in most cases.

`drawable_ID` : | The drawable.
`x1` : | x coordinate of the upper left corner of selection bounds.
`y1` : | y coordinate of the upper left corner of selection bounds.
`x2` : | x coordinate of the lower right corner of selection bounds.
`y2` : | y coordinate of the lower right corner of selection bounds.
Returns : | TRUE if there is a selection.

Find the bounding box of the current selection in relation to the specified drawable.

This procedure returns whether there is an intersection between the drawable and the selection. Unlike `gimp_drawable_mask_bounds()`, the intersection's bounds are returned as x, y, width, height. If there is no selection this function returns TRUE and the returned bounds are the extents of the whole drawable.

`drawable_ID` : | The drawable.
`x` : | x coordinate of the upper left corner of the intersection.
`y` : | y coordinate of the upper left corner of the intersection.
`width` : | width of the intersection.
`height` : | height of the intersection.
Returns : | TRUE if the returned area is not empty.
