Description

A GfImage is a abstract representation of static images. Since nothing is known about the image, like it's format, we can not preform any sort of modifications to it.

typedef struct _GfImage GfImage;

GfImage is an opaque structure that should not be used directly.

gf_image_new_from_file ()

GfImage*    gf_image_new_from_file          (const gchar *filename);

Creates a new GfImage from a file.

`filename` :	The name of the file to create the image from.
Returns :	The new GfImage or NULL.

gf_image_new_from_data ()

GfImage*    gf_image_new_from_data          (const guchar *data,
                                             gsize data_sz);

Creates a new GfImage from data.

`data` :	The image data.
`data_sz` :	The size of the image data.
Returns :	The new GfImage or NULL.

gf_image_set_data ()

void        gf_image_set_data               (GfImage *image,
                                             const guchar *data,
                                             gsize data_sz);

`data_sz` :	The size of `data`.

gf_image_get_data ()

const guchar* gf_image_get_data             (const GfImage *image,
                                             gsize *data_sz);
