Struct gdk_pixbuf::PixbufFormat

pub struct PixbufFormat { /* private fields */ }

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.

GLib type: Boxed type with copy-on-clone semantics.

Implementations

impl PixbufFormat

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

Return the inner pointer to the underlying C value.

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

Borrows the underlying C value.

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

Borrows the underlying C value mutably.

impl PixbufFormat

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

Returns a description of the format.

Returns

a description of the format.

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

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

Returns

an array of filename extensions

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

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

Returns the mime types supported by the format.

Returns

an array of mime types

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

Returns the name of the format.

Returns

the name of the format.

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.

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

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.

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.

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

Trait Implementations

impl Clone for PixbufFormat

fn clone(&self) -> Self

Copies the boxed type with the type-specific copy function.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PixbufFormat

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<PixbufFormat> for Value

fn from(o: PixbufFormat) -> Self

Converts to this type from the input type.

impl HasParamSpec for PixbufFormat

type ParamSpec = ParamSpecBoxed

type SetValue = PixbufFormat

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecBoxedBuilder<'_, PixbufFormat>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for PixbufFormat

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PixbufFormat

fn cmp(&self, other: &PixbufFormat) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

impl PartialEq for PixbufFormat

fn eq(&self, other: &PixbufFormat) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
