## Description

Functions to manipulate a plug-in's context.

## Details

### gimp_context_push ()

    gboolean            gimp_context_push                   (void);

Pushes a context to the top of the plug-in's context stack.

This procedure creates a new context by copying the current context. This copy becomes the new current context for the calling plug-in until it is popped again.

Returns : | TRUE on success.

Since GIMP 2.2

### gimp_context_pop ()

    gboolean            gimp_context_pop                    (void);

Pops the topmost context from the plug-in's context stack.

This procedure creates a new context and makes it the current context for the calling plug-in.

Returns : | TRUE on success.

Since GIMP 2.2

### gimp_context_get_foreground ()

    gboolean            gimp_context_get_foreground         (GimpRGB *foreground);

Get the current GIMP foreground color.

This procedure returns the current GIMP foreground color. The foreground color is used in a variety of tools such as paint tools, blending, and bucket fill.

`foreground` : | The foreground color.
Returns : | TRUE on success.

Since GIMP 2.2

### gimp_context_set_foreground ()

    gboolean            gimp_context_set_foreground         (const GimpRGB *foreground);

Set the current GIMP foreground color.

This procedure sets the current GIMP foreground color. After this is set, operations which use foreground such as paint tools, blending, and bucket fill will use the new value.

`foreground` : | The foreground color.
Returns : | TRUE on success.

Since GIMP 2.2

### gimp_context_get_background ()

    gboolean            gimp_context_get_background         (GimpRGB *background);

Get the current GIMP background color.

This procedure returns the current GIMP background color. The background color is used in a variety of tools such as blending, erasing (with non-alpha images), and image filling.

`background` : | The background color.
Returns : | TRUE on success.

Since GIMP 2.2

### gimp_context_set_background ()

    gboolean            gimp_context_set_background         (const GimpRGB *background);

Set the current GIMP background color.

This procedure sets the current GIMP background color. After this is set, operations which use background such as blending, filling images, clearing, and erasing (in non-alpha images) will use the new value.

`background` : | The background color.
Returns : | TRUE on success.

Since GIMP 2.2

### gimp_context_set_default_colors ()

    gboolean            gimp_context_set_default_colors     (void);

Set the current GIMP foreground and background colors to black and white.

This procedure sets the current GIMP foreground and background colors to their initial default values, black and white.

Returns : | TRUE on success.

Since GIMP 2.2

### gimp_context_swap_colors ()

    gboolean            gimp_context_swap_colors            (void);

Swap the current GIMP foreground and background colors.

This procedure swaps the current GIMP foreground and background colors, so that the new foreground color becomes the old background color and vice versa.

Returns : | TRUE on success.

Since GIMP 2.2

### gimp_context_get_opacity ()

    gdouble             gimp_context_get_opacity            (void);

### gimp_context_set_opacity ()

    gboolean            gimp_context_set_opacity            (gdouble opacity);

Set the opacity.

This procedure modifies the opacity setting. The value should be a floating point number between 0 and 100.

`opacity` : | The opacity.
Returns : | TRUE on success.

Since GIMP 2.2

### gimp_context_get_paint_mode ()

    GimpLayerModeEffects gimp_context_get_paint_mode        (void);

Get the paint mode.

This procedure returns the paint-mode setting. The return value is an integer which corresponds to the values listed in the argument description.

Returns : | The paint mode.

Since GIMP 2.2

### gimp_context_set_paint_mode ()

    gboolean            gimp_context_set_paint_mode         (GimpLayerModeEffects paint_mode);

Set the paint mode.

This procedure modifies the paint_mode setting.

`paint_mode` : | The paint mode.
Returns : | TRUE on success.

Since GIMP 2.2

### gimp_context_get_brush ()

    gchar*              gimp_context_get_brush              (void);

Retrieve the currently active brush.

This procedure returns the nme of the currently active brush. All paint operations and stroke operations use this brush to control the application of paint to the image.

Returns : | The name of the active brush.

Since GIMP 2.2

### gimp_context_set_brush ()

    gboolean            gimp_context_set_brush              (const gchar *name);

Set the specified brush as the active brush.

This procedure allows the active brush to be set by specifying its name. The name is simply a string which corresponds to one of the names of the installed brushes. If there is no matching brush found, this procedure will return an error. Otherwise, the specified brush becomes active and will be used in all subsequent paint operations.

`name` : | The name o the brush.
