## Description

Operations on complete images: creation, resizing/rescaling, and operations involving multiple layers.

## Functions

### gimp_image_list ()

    gint *
    gimp_image_list (gint *num_images);

Returns the list of images currently open.

This procedure returns the list of images currently open in GIMP.

#### Parameters

num_images | The number of images currently open. |

#### Returns

The list of images currently open. The returned value must be freed with `g_free()`.

### gimp_image_new ()

    gint32
    gimp_image_new (gint width,
                    gint height,
                    GimpImageBaseType type);

Creates a new image with the specified width, height, and type.

Creates a new image, undisplayed, with the specified extents and type. A layer should be created and added before this image is displayed, or subsequent calls to `gimp_display_new()` with this image as an argument will fail. Layers can be created using the `gimp_layer_new()` commands. They can be added to an image using the `gimp_image_insert_layer()` command.

If your image's type if INDEXED, a colormap must also be added with `gimp_image_set_colormap()`. An indexed image without a colormap will output unexpected colors.

#### Parameters

width | The width of the image. |
height | The height of the image. |
type | The type of image. |

#### Returns

The ID of the newly created image.

### gimp_image_new_with_precision ()

    gint32
    gimp_image_new_with_precision (gint width,

                                   GimpImageBaseType type,
                                   GimpPrecision precision);

Creates a new image with the specified width, height, type and precision.

Creates a new image, undisplayed with the specified extents, type and precision. Indexed images can only be created at GIMP_PRECISION_U8_GAMMA precision. See `gimp_image_new()` for further details.

#### Parameters

width | The width of the image. |
height | The height of the image. |
type | The type of image. |
precision | The precision. |

#### Returns

The ID of the newly created image.

Since: 2.10

### gimp_image_get_uri ()

    gchar *
    gimp_image_get_uri (gint32 image_ID);

Returns the URI for the specified image.

This procedure returns the URI associated with the specified image. The image has an URI only if it was loaded or imported from a file or has since been saved or exported. Otherwise, this function returns `NULL`. See also gimp-image-get-imported-uri to get the URI of the current file if it was imported from a non-GIMP file format and not yet saved, or gimp-image-get-exported-uri if the image has been exported to a non-GIMP file format.

#### Parameters

image_ID | The image. |

#### Returns

The URI. The returned value must be freed with `g_free()`.

Since: 2.8

### gimp_image_get_xcf_uri ()

    gchar *
    gimp_image_get_xcf_uri (gint32 image_ID);

Returns the XCF URI for the specified image.

This procedure returns the XCF URI associated with the image. If there is no such URI, this procedure returns `NULL`.

#### Parameters

image_ID | The image. |

#### Returns

The imported URI. The returned value must be freed with `g_free()`.

Since: 2.8

### gimp_image_get_exported_uri ()

    gchar *
    gimp_image_get_exported_uri (gint32 image_ID);

Returns the exported URI for the specified image.

This procedure returns the URI associated with the specified image if the image was exported a non-native GIMP format. If the image was not exported, this procedure returns `NULL`.

#### Returns

The exported URI. The returned value must be freed with `g_free()`.

Since: 2.8

### gimp_image_get_imported_uri ()

    gchar *
    gimp_image_get_imported_uri (gint32 image_ID);

Returns the imported URI for the specified image.

This procedure returns the URI associated with the specified image if the image was imported from a non-native Gimp format. If the image was not imported, or has since been saved in the native Gimp format, this procedure returns `NULL`.

#### Parameters

image_ID | The image. |

#### Returns

The imported URI. The returned value must be freed with `g_free()`.

Since: 2.8

### gimp_image_duplicate ()

### gimp_image_delete ()

    gboolean
    gimp_image_delete (gint32 image_ID);

Delete the specified image.

If there are no displays associated with this image it will be deleted. This means that you can not delete an image through the PDB that was created by the user. If the associated display was however created through the PDB and you know the display ID, you may delete the display. Removal of the last associated display will then delete the image.

#### Parameters

image_ID | The image. |

                           GimpRGB *color);

Determine the color at the given drawable coordinates

This tool determines the color at the specified coordinates. The returned color is an RGB triplet even for grayscale and indexed drawables. If the coordinates lie outside of the extents of the specified drawable, then an error is returned. If the drawable has an alpha channel, the algorithm examines the alpha value of the drawable at the coordinates. If the alpha value is completely transparent (0), then an error is returned. If the sample_merged parameter is TRUE, the data of the composite image will be used instead of that for the specified drawable. This is equivalent to sampling for colors after merging all visible layers. In the case of a merged sampling, the supplied drawable is ignored.

#### Parameters

image_ID | The image. |
drawable_ID | The drawable to pick from. |
x | x coordinate of upper-left corner of rectangle. |
y | y coordinate of upper-left corner of rectangle. |
sample_merged | Use the composite image, not the drawable. |
sample_average | Average the color of all the pixels in a specified radius. |
average_radius | The radius of pixels to average. |
color | The return color. |

#### Returns

TRUE on success.

### gimp_image_pick_correlate_layer ()

Find the layer visible at the specified coordinates.

This procedure finds the layer which is visible at the specified coordinates. Layers which do not qualify are those whose extents do not pass within the specified coordinates, or which are transparent at the specified coordinates. This procedure will return -1 if no layer is found.

#### Parameters

x | The x coordinate for the pick. |
y | The y coordinate for the pick. |

#### Returns

#### Returns

TRUE if the image has unsaved changes.

Add the specified vectors to the image.

This procedure adds the specified vectors to the image at the given position. Since vectors groups are not currently supported, the parent argument must always be 0. The position argument specifies the location of the vectors inside the stack, starting from the top (0) and increasing. If the position is specified as -1, then the vectors is inserted above the active vectors.

image_ID | The image. |
vectors_ID | The vectors. |
parent_ID | The parent vectors. |
position | The vectors position. |

#### Returns

TRUE on success.
