Description

Functions

go_mime_to_image_format ()

char *
go_mime_to_image_format (char const *mime_type);

Parameters

mime_type

a mime type string

  

Returns

file extension for the given mime type.

go_image_format_to_mime ()

char *
go_image_format_to_mime (char const *format);

Parameters

format

a file extension string

  

Returns

corresponding mime type.

go_image_get_format_info ()

GOImageFormatInfo const *
go_image_get_format_info (GOImageFormat format);

Retrieves infromation associated to format .

Parameters

format

a GOImageFormat

  

Returns

a GOImageFormatInfo struct.

go_image_get_format_from_name ()

GOImageFormat
go_image_get_format_from_name (char const *name);

Parameters

name

a string

  

Returns

corresponding GOImageFormat.

go_image_get_formats_with_pixbuf_saver ()

GSList *
go_image_get_formats_with_pixbuf_saver
                               (void);

Returns

a list of GOImageFormat that can be created from a pixbuf.

GO_IMAGE()

#define GO_IMAGE(o) (G_TYPE_CHECK_INSTANCE_CAST ((o), GO_TYPE_IMAGE, GOImage))

GO_IS_IMAGE()

#define GO_IS_IMAGE(o) (G_TYPE_CHECK_INSTANCE_TYPE ((o), GO_TYPE_IMAGE))

go_image_get_type ()

GType
go_image_get_type (void);

go_image_get_cairo ()

cairo_t *
go_image_get_cairo (GOImage *image);

go_image_create_cairo_pattern ()

cairo_pattern_t *
go_image_create_cairo_pattern (GOImage *image);

Parameters

image

a GOImage.

  

Returns

a cairo_pattern usable for cairo_set_source.

Note: this function has lifespan issues. The resulting pattern in only valid until (a) a pixbuf is set for the, or (b) a pixbuf is _read_ from the image. In either of these cases, the pattern must have been destroyed beforehand. In particular, if the pattern has been attached to a surface, that surface must either be finished itself, or have had a new pattern attached. See 632439.
