Pixdata

A #GdkPixdata contains pixbuf information in a form suitable for serialization and streaming.

class Pixdata {

GdkPixdata* gdkPixdata;

bool ownedRef;

GdkPixdata* getPixdataStruct();

void* getStruct();

this(GdkPixdata* gdkPixdata, bool ownedRef);

bool deserialize(ubyte[] stream);

void* fromPixbuf(Pixbuf pixbuf, bool useRle);

ubyte[] serialize();

StringG toCsource(string name, GdkPixdataDumpType dumpType);

}

Constructors

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

Members

Functions

deserialize bool deserialize(ubyte[] stream): Deserializes (reconstruct) a #GdkPixdata structure from 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. The @pixdata contents are reconstructed byte by byte and are checked for validity. This function may fail with %GDK_PIXBUF_ERROR_CORRUPT_IMAGE or %GDK_PIXBUF_ERROR_UNKNOWN_TYPE.
fromPixbuf void* fromPixbuf(Pixbuf pixbuf, bool useRle): Converts a #GdkPixbuf to a #GdkPixdata. If @use_rle is %TRUE, the pixel data is run-length encoded into newly-allocated memory and a pointer to that memory is returned.
getPixdataStruct GdkPixdata* getPixdataStruct(): 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.

Variables

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