#### Classes

BatchProcedure | Batch procedures implement an interpreter able to run commands as input.
Brush | Installable object used by painting and stroking tools.
Channel | Functions for manipulating channels.
Choice |
ColorConfig | Color management settings.
ColorProfile | Definitions and Functions relating to LCMS.
ColorTransform | Definitions and Functions relating to LCMS.
ConfigPath |
Curve |
Display | Functions to create, delete and flush displays (views) on an image.
Drawable | Functions to manipulate drawables.
DrawableFilter | Operations on drawable filters: creation, editing.
DrawableFilterConfig | The base class for `GimpDrawableFilter` specific config objects. since: 3.0
ExportOptions | A class holding generic export options.
ExportProcedure | Export procedures implement image export.
FileProcedure | File procedures implement file support. They cannot be created directly. Instead, you will create an instance of one of the subclasses (such as export or load procedures). This provides a common interface for file-related functions on these objects.
Font | Installable object used by text tools.
Gradient | Installable object used by the gradient rendering tool.
GroupLayer | Operations on a group layer.
Image | Operations on complete images: creation, resizing/rescaling, and operations involving multiple layers.
ImageProcedure | A `GimpProcedure` subclass that makes it easier to write standard plug-in procedures that operate on drawables.
Item | Functions to manipulate items.
Layer | Operations on a single layer.
LayerMask |
LinkLayer | Functions for querying and manipulating link layers.
LoadProcedure | A `GimpProcedure` subclass that makes it easier to write file load procedures.
Memsize | Functions to (de)serialize a given memory size.
Metadata | Basic functions for handling `GimpMetadata` objects.
Module | `GimpModule` is a generic mechanism to dynamically load modules into GIMP. It is a `GTypeModule` subclass, implementing module loading using `GModule`. `GimpModule` does not know which functionality is implemented by the modules, it just provides a framework to get arbitrary `GType` implementations loaded from disk.
ModuleDB | Keeps a list of `GimpModule`‘s found in a given searchpath.
Palette | Installable object, a small set of colors a user can choose from.

stack_trace_print | Attempts to generate a stack trace at current code position in `prog_name`. `prog_name` is mostly a helper and can be set to NULL. Nevertheless if set, it has to be the current program name (argv[0]). This function is not meant to generate stack trace for third-party programs, and will attach the current process id only. Internally, this function uses `gdb` or `lldb` if they are available, or the `stacktrace()` API on platforms where it is available. It always fails on Win32. since: 2.10
stack_trace_query | This is mostly the same as `g_on_error_query()` except that we use our own backtrace function, much more complete. `prog_name` must be the current program name (argv[0]). It does nothing on Win32. since: 2.10

type_get_translation_domain | Retrieves the gettext translation domain identifier that has been previously set using gimp_type_set_translation_domain(). You should not need to use this function directly, use `gimp_enum_get_value()` or `gimp_enum_value_get_desc()` instead. since: 2.2
type_set_translation_context | This function attaches a constant string as a translation context to a `GType`. The only purpose of this function is to use it when registering a #G_TYPE_ENUM with translatable value names. since: 2.8
type_set_translation_domain | This function attaches a constant string as a gettext translation domain identifier to a `GType`. The only purpose of this function is to use it when registering a #G_TYPE_ENUM with translatable value names. since: 2.2

vector_2d_to_3d_val | This function is identical to `gimp_vector_2d_to_3d()` but the position of the `observer` and the resulting point `p` are passed by value rather than by reference.
vector_3d_to_2d | Convert the given 3D point to 2D (project it onto the viewing plane, (sx, sy, 0) - (sx + w, sy + h, 0). The input is assumed to be in the unit square (0, 0, z) - (1, 1, z). The viewpoint of the observer is passed in vp.
version | Returns the host GIMP version.

#### Constants

API_VERSION |
CHECK_DARK | The dark gray value for the default checkerboard pattern.
CHECK_LIGHT | The dark light value for the default checkerboard pattern.
CHECK_SIZE | The default checkerboard size in pixels. This is configurable in the core but GIMP plug-ins can’t access the user preference and should use this constant instead.
CHECK_SIZE_SM | The default small checkerboard size in pixels.
CONFIG_PARAM_AGGREGATE | The object property is to be treated as part of the parent object.
CONFIG_PARAM_CONFIRM | Changes to this property should be confirmed by the user before being applied.
CONFIG_PARAM_DEFAULTS | Don’t serialize this property if it has the default value.
CONFIG_PARAM_DONT_COMPARE | Ignore this property when comparing objects.
CONFIG_PARAM_FLAG_SHIFT | Minimum shift count to be used for core application defined `GParamFlags`.
CONFIG_PARAM_FLAGS | The default flags that should be used for serializable `GimpConfig` properties.
CONFIG_PARAM_IGNORE | This property exists for obscure reasons or is needed for backward compatibility. Ignore the value read and don’t serialize it.
CONFIG_PARAM_RESTART | Changes to this property take effect only after a restart.
CONFIG_PARAM_SERIALIZE | A property that can and should be serialized and deserialized.
MAJOR_VERSION | The major GIMP version number.
MAX_IMAGE_SIZE | The maximum width and height of a GIMP image in pixels. This is a somewhat arbitrary value that can be used when an upper value for pixel sizes is needed; for example to give a spin button an upper limit.
MAX_MEMSIZE | A large but arbitrary value that can be used when an upper limit for a memory size (in bytes) is needed. It is smaller than `G_MAXDOUBLE` since the `GimpMemsizeEntry` doesn’t handle larger values.
MAX_RESOLUTION | The maximum resolution of a GIMP image in pixels per inch. This is a somewhat arbitrary value that can be used to when an upper value for a resolution is needed. GIMP will not accept resolutions larger than this value.
MICRO_VERSION | The micro GIMP version number.
MIN_IMAGE_SIZE | The minimum width and height of a GIMP image in pixels.
MIN_RESOLUTION | The minimum resolution of a GIMP image in pixels per inch. This is a somewhat arbitrary value that can be used when a lower value for a resolution is needed. GIMP will not accept resolutions smaller than this value.
MINOR_VERSION | The minor GIMP version number.
MODULE_ABI_VERSION | The version of the module system’s ABI. Modules put this value into `GimpModuleInfo`‘s `abi_version` field so the code loading the modules can check if it was compiled against the same module ABI the modules are compiled against.
PARAM_DONT_SERIALIZE | This property will be ignored when serializing and deserializing. This is useful for GimpProcedure arguments for which you never want the last run values to be restored.
PARAM_FLAG_SHIFT | Minimum shift count to be used for libgimpconfig defined `GParamFlags` (see libgimpconfig/gimpconfig-params.h).
PARAM_NO_VALIDATE | Since 3.0
PARAM_READABLE |
PARAM_READWRITE |
PARAM_STATIC_STRINGS |
PARAM_WRITABLE |
PARASITE_ATTACH_GRANDPARENT |
PARASITE_ATTACH_PARENT |
PARASITE_GRANDPARENT_PERSISTENT |
PARASITE_GRANDPARENT_UNDOABLE |
PARASITE_PARENT_PERSISTENT |
PARASITE_PARENT_UNDOABLE |
PARASITE_PERSISTENT | A persistent parasite will be saved to XCF and can be used again after reloading. A non persistent parasite will only be available during the current session. See `GimpParasite`.
PARASITE_UNDOABLE | An undoable parasite that was added, can be removed using the Undo action. If this flag is not set, undoing will not change the parasite. See `GimpParasite`.
PIXPIPE_MAXDIM |
VERSION | The GIMP version as a string.
