Pixdata

A pixel buffer suitable for serialization and streaming.

Using GdkPixdata, images can be compiled into an application, making it unnecessary to refer to external image files at runtime.

GdkPixbuf includes a utility named gdk-pixbuf-csource, which can be used to convert image files into GdkPixdata structures suitable for inclusion in C sources. To convert the GdkPixdata structures back into a GdkPixbuf, use gdk_pixbuf_from_pixdata().

Constructors

this this(GdkPixdata* gdkPixdata, bool ownedRef): Sets our main struct and passes it to the parent class.

Destructor

~this ~this(): Undocumented in source.

Members

Functions

deserialize bool deserialize(ubyte[] stream): Deserializes (reconstruct) a #GdkPixdata structure from a byte stream.
fromPixbuf ubyte[] fromPixbuf(Pixbuf pixbuf, bool useRle): Converts a GdkPixbuf to a GdkPixdata.
getPixdataStruct GdkPixdata* getPixdataStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
serialize ubyte[] serialize(): Serializes a #GdkPixdata structure into a byte stream. The byte stream consists of a straightforward writeout of the #GdkPixdata fields in network byte order, plus the @pixel_data bytes the structure points to.
toCsource StringG toCsource(string name, GdkPixdataDumpType dumpType): Generates C source code suitable for compiling images directly into programs.

Properties

height uint height [@property getter]
uint height [@property setter]: Height of the image in pixels
length int length [@property getter]
int length [@property setter]: less than 1 to disable length checks, otherwise GDK_PIXDATA_HEADER_LENGTH plus the length of pixel_data
magic uint magic [@property getter]
uint magic [@property setter]: magic number. A valid GdkPixdata structure must have GDK_PIXBUF_MAGIC_NUMBER here
pixdataType uint pixdataType [@property getter]
uint pixdataType [@property setter]: information about colorspace, sample width and encoding, in a GdkPixdataType
rowstride uint rowstride [@property getter]
uint rowstride [@property setter]: Distance in bytes between rows
width uint width [@property getter]
uint width [@property setter]: Width of the image in pixels

Variables

gdkPixdata GdkPixdata* gdkPixdata;: the main Gtk struct
ownedRef bool ownedRef;: Undocumented in source.

Detailed Description

Deprecated: GdkPixdata should not be used any more. GResource should be used to save the original compressed images inside the program's binary
