Description:

Content:

Namespaces:

• Gdk

Classes:

• Pixbuf - A pixel buffer.
• PixbufAnimation - An opaque object representing an animation.
• PixbufAnimationIter - An opaque object representing an iterator which points to a certain position in an animation.
• PixbufFormat - A `GdkPixbufFormat` contains information about the image format accepted by a module.
• PixbufLoader - Incremental image loader.
• PixbufNonAnim
• PixbufSimpleAnim - An opaque struct representing a simple animation.
• PixbufSimpleAnimIter

Structs:

• PixbufModule - A `GdkPixbufModule` contains the necessary functions to load and save images in a certain file format.
• PixbufModulePattern - The signature prefix for a module.
• Pixdata - A pixel buffer suitable for serialization and streaming.

Enums:

• Colorspace - This enumeration defines the color spaces that are supported by the gdk-pixbuf library.
• InterpType - Interpolation modes for scaling functions.
• PixbufAlphaMode - Control the alpha channel for drawables.
• PixbufFormatFlags - Flags which allow a module to specify further details about the supported operations.
• PixbufRotation - The possible rotations which can be passed to rotate_simple.
• PixdataDumpType - An enumeration which is used by to_csource to determine the form of C source to be generated.
• PixdataType - An enumeration containing three sets of flags for a Pixdata struct: one for the used colorspace, one for the width of the samples and one for the encoding of the pixel data.

Error domains:

• PixbufError - An error code in the `GDK_PIXBUF_ERROR` domain.

Constants:

• public const int PIXBUF_MAGIC_NUMBER
  Magic number for Pixdata structures.
• public const int PIXBUF_MAJOR
  Major version of gdk-pixbuf library, that is the "0" in "0.8.2" for example.
• public const int PIXBUF_MICRO
  Micro version of gdk-pixbuf library, that is the "2" in "0.8.2" for example.
• public const int PIXBUF_MINOR
  Minor version of gdk-pixbuf library, that is the "8" in "0.8.2" for example.
• public const string PIXBUF_VERSION
  Contains the full version of GdkPixbuf as a string.
• public const int PIXDATA_HEADER_LENGTH
  The length of a Pixdata structure without the pixel_data pointer.

Delegates:

• public delegate void PixbufDestroyNotify (uint8[] pixels)
  A function of this type is responsible for freeing the pixel array of a pixbuf.
• public delegate void* PixbufModuleBeginLoadFunc (PixbufModuleSizeFunc size_func, PixbufModulePreparedFunc prepared_func, PixbufModuleUpdatedFunc updated_func) throws Error
  Sets up the image loading state.
• public delegate void PixbufModuleFillInfoFunc (PixbufFormat info)
  Defines the type of the function used to fill a PixbufFormat structure with information about a module.
• public delegate void PixbufModuleFillVtableFunc (PixbufModule module)
  Defines the type of the function used to set the vtable of a PixbufModule when it is loaded.
• public delegate bool PixbufModuleIsSaveOptionSupportedFunc (string option_key)
• public delegate unowned PixbufAnimation PixbufModuleLoadAnimationFunc (void* f) throws Error
  Loads a file from a standard C file stream into a new `GdkPixbufAnimation`.
• public delegate unowned Pixbuf PixbufModuleLoadFunc (void* f) throws Error
  Loads a file from a standard C file stream into a new `GdkPixbuf`.
• public delegate bool PixbufModuleLoadIncrementFunc (void* context, uint8[] buf) throws Error
• public delegate unowned Pixbuf PixbufModuleLoadXpmDataFunc (string data)
  Loads XPM data into a new `GdkPixbuf`.
• public delegate void PixbufModulePreparedFunc (Pixbuf pixbuf, PixbufAnimation anim)
  Defines the type of the function that gets called once the initial setup of pixbuf is done.
• public delegate bool PixbufModuleSaveFunc (void* f, Pixbuf pixbuf, string[] param_keys, string[] param_values) throws Error
  Saves a `GdkPixbuf` into a standard C file stream.
• public delegate bool PixbufModuleSaveToCallbackFunc (PixbufSaveFunc save_func, Pixbuf pixbuf, string[] option_keys, string[] option_values) throws Error
• public delegate void PixbufModuleSizeFunc (int width, int height)
  Defines the type of the function that gets called once the size of the loaded image is known.
• public delegate bool PixbufModuleStopLoadFunc (void* context) throws Error
  Finalizes the image loading state.
• public delegate void PixbufModuleUpdatedFunc (Pixbuf pixbuf, int x, int y, int width, int height)
  Defines the type of the function that gets called every time a region of pixbuf is updated.
• public delegate bool PixbufSaveFunc (uint8[] buf) throws Error
  Save functions used by [method@GdkPixbuf.
