Struct

GdkPixdataPixdata

Description [src]

struct GdkPixdata {
  guint32 magic;
  gint32 length;
  guint32 pixdata_type;
  guint32 rowstride;
  guint32 width;
  guint32 height;
  guint8* pixel_data;
}

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().

Structure members

`magic`	Magic number. A valid `GdkPixdata` structure must have `GDK_PIXBUF_MAGIC_NUMBER` here.
`length`	Less than 1 to disable length checks, otherwise `GDK_PIXDATA_HEADER_LENGTH` plus the length of `pixel_data`
`pixdata_type`	Information about colorspace, sample width and encoding, in a `GdkPixdataType`
`rowstride`	Distance in bytes between rows.
`width`	Width of the image in pixels.
`height`	Height of the image in pixels.
`pixel_data`	`width` x `height` pixels, encoded according to `pixdata_type` and `rowstride`

Deprecated since:	2.32
`GdkPixdata` should not be used any more. `GResource` should be used to save the original compressed images inside the program’s binary.

Instance methods

gdk_pixdata_deserialize

Deserializes (reconstruct) a GdkPixdata structure from a byte stream.

Deprecated since: 2.32

gdk_pixdata_from_pixbuf

Converts a GdkPixbuf to a GdkPixdata.

Deprecated since: 2.32

gdk_pixdata_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.

Deprecated since: 2.32

gdk_pixdata_to_csource

Generates C source code suitable for compiling images directly into programs.

Deprecated since: 2.32
