type
PixbufModuleUpdatedFunc = Pixbuf -> Int32 -> Int32 -> Int32 -> Int32 -> IO ()gi-gdkpixbuf GI.GdkPixbuf.Callbacks Defines the type of the function that gets called every time a region of pixbuf is updated. PixbufLoader uses a function of this type to emit the "<link linkend="GdkPixbufLoader-area-updated">area_updated</link>" signal. Since: 2.2

type
PixbufSaveFunc = ByteString -> IO (Bool, GError)gi-gdkpixbuf GI.GdkPixbuf.Callbacks Save functions used by Pixbuf.save_to_callback(). This function is called once for each block of bytes that is "written" by gdk_pixbuf_save_to_callback(). If successful it should return TRUE; if an error occurs it should set error and return FALSE, in which case gdk_pixbuf_save_to_callback() will fail with the same error. Since: 2.4
type
PixbufSaveFunc_WithClosures = ByteString -> Ptr () -> IO (Bool, GError)gi-gdkpixbuf GI.GdkPixbuf.Callbacks Save functions used by Pixbuf.save_to_callback(). This function is called once for each block of bytes that is "written" by gdk_pixbuf_save_to_callback(). If successful it should return TRUE; if an error occurs it should set error and return FALSE, in which case gdk_pixbuf_save_to_callback() will fail with the same error. Since: 2.4

PIXBUF_VERSION :: Textgi-gdkpixbuf GI.GdkPixbuf.Constants Contains the full version of GdkPixbuf as a string. This is the version being compiled against; contrast with gdk_pixbuf_version.

gi-gdkpixbuf GI.GdkPixbuf.Enums Deprecated: (Since version 2.42)There is no user of GdkPixbufAlphaMode in GdkPixbuf,and the Xlib utility functions have been split out to their ownlibrary, gdk-pixbuf-xlib
PixbufAlphaModeBilevel :: PixbufAlphaModegi-gdkpixbuf GI.GdkPixbuf.Enums A bilevel clipping mask (black and white) will be created and used to draw the image. Pixels below 0.5 opacity will be considered fully transparent, and all others will be considered fully opaque.
