                                             gboolean undo);

Merge the shadow buffer with the specified drawable.

This procedure combines the contents of the image'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.
undo : Push merge to undo stack?
Returns : TRUE on success.


gimp_drawable_fill ()

gboolean    gimp_drawable_fill              (gint32 drawable_ID,
                                             GimpFillType fill_type);

Fill the drawable with the specified fill mode.

This procedure fills the drawable with the fill mode. 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 the bucket fill tool because it fills regardless of a selection

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

                                             gint height);

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 with: {x->0, y->0, w->width, h->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.
Returns : TRUE on success.

                                             gint *y2);

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

This procedure returns the whether there is a selection. If there is one, the upper left and lower righthand corners of its bounding box are returned. These coordinates are specified relative to the drawable's origin, and bounded by the drawable's extents.

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.

drawable_ID : The drawable.
Returns : Does the drawable have an alpha channel?


gimp_drawable_type_with_alpha ()

GimpImageType gimp_drawable_type_with_alpha (gint32 drawable_ID);

Returns the drawable's type with alpha.

This procedure returns the drawable's type if an alpha channel were added. If the type is currently Gray, for instance, the returned type would be GrayA. If the drawable already has an alpha channel, the drawable's type is simply returned.

drawable_ID : The drawable.
Returns : The drawable's type with alpha.


gimp_drawable_is_rgb ()

gboolean    gimp_drawable_is_rgb            (gint32 drawable_ID);

Returns : non-zero if the drawable is an RGB type.


gimp_drawable_is_gray ()

gboolean    gimp_drawable_is_gray           (gint32 drawable_ID);

Returns whether the drawable is a grayscale type.

This procedure returns non-zero if the specified drawable is of type { Gray, GrayA }.

drawable_ID : The drawable.
Returns : Bytes per pixel.


gimp_drawable_width ()

gint        gimp_drawable_width             (gint32 drawable_ID);

Returns the width of the drawable.

This procedure returns the specified drawable's width in pixels.

drawable_ID : The drawable.

gimp_drawable_height ()

gint        gimp_drawable_height            (gint32 drawable_ID);
