gdkPixbufSaveToCallback

Description

Saves pixbuf in format type by feeding the produced data to a callback. Can be used when you want to store the image to something other than a file, such as an in-memory buffer or a socket. If error is set, FALSE will be returned. Possible errors include those in the GDK_PIXBUF_ERROR domain and whatever the save function generates.

Usage

gdkPixbufSaveToCallback(object, save.func, user.data, type, ..., 
    .errwarn = TRUE)

Arguments

`object`	a `GdkPixbuf`.
`save.func`	a function that is called to save each block of data that the save routine generates.
`user.data`	user data to pass to the save function.
`type`	name of file format.
`...`	whether an error was set
`.errwarn`	Whether to issue a warning on error or fail silently

Details

See gdkPixbufSave for more details. Since 2.4

Value

A list containing the following elements:

`retval`	[logical] whether an error was set
`error`	return location for error, or `NULL`. [ allow-none ]
