Struct gdk_pixbuf::PixbufFormat

source ·
pub struct PixbufFormat { /* private fields */ }
Expand description

A PixbufFormat contains information about the image format accepted by a module.

Only modules should access the fields directly, applications should use the gdk_pixbuf_format_* family of functions.

Implementations§

source§

impl PixbufFormat

source

pub fn as_ptr(&self) -> *mut GdkPixbufFormat

Return the inner pointer to the underlying C value.

source

pub unsafe fn from_glib_ptr_borrow<'a>( ptr: *const *const GdkPixbufFormat ) -> &'a Self

Borrows the underlying C value.

source

pub unsafe fn from_glib_ptr_borrow_mut<'a>( ptr: *mut *mut GdkPixbufFormat ) -> &'a mut Self

Borrows the underlying C value mutably.

source§

impl PixbufFormat

source

pub fn description(&self) -> Option<GString>

Returns a description of the format.

§Returns

a description of the format.

source

pub fn extensions(&self) -> Vec<GString>

Returns the filename extensions typically used for files in the given format.

§Returns

an array of filename extensions

source

pub fn license(&self) -> Option<GString>

Returns information about the license of the image loader for the format.

The returned string should be a shorthand for a well known license, e.g. “LGPL”, “GPL”, “QPL”, “GPL/QPL”, or “other” to indicate some other license.

§Returns

a string describing the license of the pixbuf format

source

pub fn mime_types(&self) -> Vec<GString>

Returns the mime types supported by the format.

§Returns

an array of mime types

source

pub fn name(&self) -> Option<GString>

Returns the name of the format.

§Returns

the name of the format.

source

pub fn is_disabled(&self) -> bool

Returns whether this image format is disabled.

See gdk_pixbuf_format_set_disabled().

§Returns

whether this image format is disabled.

source

pub fn is_save_option_supported(&self, option_key: &str) -> bool

Returns TRUE if the save option specified by @option_key is supported when saving a pixbuf using the module implementing @self.

See gdk_pixbuf_save() for more information about option keys.

§option_key

the name of an option

§Returns

TRUE if the specified option is supported

source

pub fn is_scalable(&self) -> bool

Returns whether this image format is scalable.

If a file is in a scalable format, it is preferable to load it at the desired size, rather than loading it at the default size and scaling the resulting pixbuf to the desired size.

§Returns

whether this image format is scalable.

source

pub fn is_writable(&self) -> bool

Returns whether pixbufs can be saved in the given format.

§Returns

whether pixbufs can be saved in the given format.

source

pub fn set_disabled(&mut self, disabled: bool)

Disables or enables an image format.

If a format is disabled, GdkPixbuf won’t use the image loader for this format to load images.

Applications can use this to avoid using image loaders with an inappropriate license, see gdk_pixbuf_format_get_license().

§disabled

TRUE to disable the format @self
