type
PixbufDestroyNotify_WithClosures = Ptr Word8 -> Ptr () -> IO ()gi-gdkpixbuf GI.GdkPixbuf.Callbacks A function of this type is responsible for freeing the pixel array of a pixbuf. The pixbufNewFromData function lets you pass in a pre-allocated pixel array so that a pixbuf can be created from it; in this case you will need to pass in a function of type GdkPixbufDestroyNotify so that the pixel data can be freed when the pixbuf is finalized.
type
PixbufModuleFillInfoFunc = PixbufFormat -> IO ()gi-gdkpixbuf GI.GdkPixbuf.Callbacks Defines the type of the function used to fill a PixbufFormat structure with information about a module. Since: 2.2
type
PixbufModuleFillVtableFunc = PixbufModule -> IO ()gi-gdkpixbuf GI.GdkPixbuf.Callbacks Defines the type of the function used to set the vtable of a PixbufModule when it is loaded. Since: 2.2
type
PixbufModuleIncrementLoadFunc = Ptr () -> ByteString -> IO ()gi-gdkpixbuf GI.GdkPixbuf.Callbacks Incrementally loads a buffer into the image data.
type
PixbufModuleLoadAnimationFunc = Ptr () -> IO PixbufAnimationgi-gdkpixbuf GI.GdkPixbuf.Callbacks Loads a file from a standard C file stream into a new GdkPixbufAnimation. In case of error, this function should return NULL and set the error argument.
type
PixbufModuleLoadFunc = Ptr () -> IO Pixbufgi-gdkpixbuf GI.GdkPixbuf.Callbacks Loads a file from a standard C file stream into a new GdkPixbuf. In case of error, this function should return NULL and set the error argument.
type
PixbufModuleLoadXpmDataFunc = [Text] -> IO Pixbufgi-gdkpixbuf GI.GdkPixbuf.Callbacks Loads XPM data into a new GdkPixbuf.
type
PixbufModulePreparedFunc = Pixbuf -> PixbufAnimation -> IO ()gi-gdkpixbuf GI.GdkPixbuf.Callbacks Defines the type of the function that gets called once the initial setup of pixbuf is done. PixbufLoader uses a function of this type to emit the "<link linkend="GdkPixbufLoader-area-prepared">area_prepared</link>" signal. Since: 2.2
type
PixbufModulePreparedFunc_WithClosures = Pixbuf -> PixbufAnimation -> Ptr () -> IO ()gi-gdkpixbuf GI.GdkPixbuf.Callbacks Defines the type of the function that gets called once the initial setup of pixbuf is done. PixbufLoader uses a function of this type to emit the "<link linkend="GdkPixbufLoader-area-prepared">area_prepared</link>" signal. Since: 2.2
type
PixbufModuleSaveFunc = Ptr () -> Pixbuf -> Maybe [Text] -> Maybe [Text] -> IO ()gi-gdkpixbuf GI.GdkPixbuf.Callbacks Saves a GdkPixbuf into a standard C file stream. The optional param_keys and param_values arrays contain the keys and values (in the same order) for attributes to be saved alongside the image data.
