Pixdata

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 GdkPixbufs, use gdk_pixbuf_from_pixdata.

class Pixdata {

protected

GdkPixdata* gdkPixdata;

GdkPixdata* getPixdataStruct();

void* getStruct();

this(GdkPixdata* gdkPixdata);

void* fromPixbuf(Pixbuf pixbuf, int useRle);

Pixbuf gdkPixbufFromPixdata(int copyPixels);

ubyte[] serialize();

int deserialize(ubyte[] stream);

StringG toCsource(string name, GdkPixdataDumpType dumpType);

}

Constructors

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

Functions

deserialize int 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, int 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.
gdkPixbufFromPixdata Pixbuf gdkPixbufFromPixdata(int copyPixels): Converts a GdkPixdata to a GdkPixbuf. If copy_pixels is TRUE or if the pixel data is run-length-encoded, the pixel data is copied into newly-allocated memory; otherwise it is reused.
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. gdk-pixbuf ships with a program called gdk-pixbuf-csource which offers a command line interface to this function.
