char * go_mime_to_image_format (char const *mime_type);
|
a mime type string |
Returns : |
file extension for the given mime type. |
char * go_image_format_to_mime (char const *format);
|
a file extension string |
Returns : |
corresponding mime type. |
GOImageFormatInfo const * go_image_get_format_info (GOImageFormat format);
Retrieves infromation associated to format.
|
a GOImageFormat |
Returns : |
a GOImageFormatInfo struct. |
GOImageFormat go_image_get_format_from_name (char const *name);
|
a string |
Returns : |
corresponding GOImageFormat. |
GSList * go_image_get_formats_with_pixbuf_saver
(void);
Returns : |
a list of GOImageFormat that can be created from a pixbuf. |
cairo_pattern_t * go_image_create_cairo_pattern (GOImage *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. |
