Pixdata

A gdkpixbuf.Pixdata 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.

A destructor is present on this object, but not explicitly documented in the source.

deserialize bool deserialize(ubyte[] stream): Deserializes (reconstruct) a gdkpixbuf.Pixdata structure from a byte stream. The byte stream consists of a straightforward writeout of the gdkpixbuf.Pixdata 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 gdk.Pixbuf to a gdkpixbuf.Pixdata 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 gdkpixbuf.Pixdata structure into a byte stream. The byte stream consists of a straightforward writeout of the gdkpixbuf.Pixdata 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 gdkpixbuf.Pixdata 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.
