Namespaces:

• Gdk

Classes:

• Pixbuf - This is the main structure in the &gdk-pixbuf; library. It is used to represent images. It contains information about the image's pixel data, its color space, bits per sample, width and height, and the rowstride (the number of bytes between the start of one row and the start of the next).
• PixbufAnimation - An opaque struct representing an animation.
• PixbufAnimationIter - An opaque struct representing an iterator which points to a certain position in an animation.
• PixbufFormat -
• PixbufLoader - The PixbufLoader struct contains only private fields.
• PixbufSimpleAnim - An opaque struct representing a simple animation.
• PixbufSimpleAnimIter -

Structs:

• Pixdata - A Pixdata contains pixbuf information in a form suitable for serialization and streaming.

Enums:

• Colorspace - This enumeration defines the color spaces that are supported by the &gdk-pixbuf; library. Currently only RGB is supported.
• InterpType - This enumeration describes the different interpolation modes that can be used with the scaling functions. GDK_INTERP_NEAREST is the fastest scaling method, but has horrible quality when scaling down. GDK_INTERP_BILINEAR is the best choice if you aren't sure what to choose, it has a good speed/quality balance.
• PixbufAlphaMode - These values can be passed to gdk_pixbuf_render_to_drawable_alpha to control how the alpha channel of an image should be handled. This function can create a bilevel clipping mask (black and white) and use it while painting the image. In the future, when the X Window System gets an alpha channel extension, it will be possible to do full alpha compositing onto arbitrary drawables. For now both cases fall back to a bilevel clipping mask.
• PixbufRotation - The possible rotations which can be passed to rotate_simple. To make them easier to use, their numerical values are the actual degrees.
• PixdataDumpType - An enumeration which is used by to_csource to determine the form of C source to be generated. The three values and GDK_PIXDATA_DUMP_MACROS are mutually exclusive, as are elements are optional flags that can be freely added.
• PixdataType - 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 PixbufError domain. Many &gdk-pixbuf; operations can cause errors in this domain, or in the FileError domain.

Constants:

• public const int PIXBUF_FEATURES_H
• public const int PIXBUF_MAGIC_NUMBER
• public const int PIXBUF_MAJOR
• public const int PIXBUF_MICRO
• public const int PIXBUF_MINOR
• public const unowned string PIXBUF_VERSION
• public const int PIXDATA_HEADER_LENGTH

Delegates:

• public delegate void PixbufDestroyNotify (uint8[] pixels)
• public delegate bool PixbufSaveFunc (uint8[] buf) throws Error
