Pixdata

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

Constructors

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

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(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.

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 + 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.
