pub struct TextureDownloader { /* private fields */ }
v4_10
only.Expand description
The TextureDownloader
is used to download the contents of a
Texture
.
It is intended to be created as a short-term object for a single download, but can be used for multiple downloads of different textures or with different settings.
TextureDownloader
can be used to convert data between different formats.
Create a Texture
for the existing format and then download it in a
different format.
GLib type: Boxed type with copy-on-clone semantics.
Implementations§
Source§impl TextureDownloader
impl TextureDownloader
Sourcepub fn as_ptr(&self) -> *mut GdkTextureDownloader
pub fn as_ptr(&self) -> *mut GdkTextureDownloader
Return the inner pointer to the underlying C value.
Sourcepub unsafe fn from_glib_ptr_borrow(ptr: &*mut GdkTextureDownloader) -> &Self
pub unsafe fn from_glib_ptr_borrow(ptr: &*mut GdkTextureDownloader) -> &Self
Borrows the underlying C value.
Sourcepub unsafe fn from_glib_ptr_borrow_mut(
ptr: &mut *mut GdkTextureDownloader,
) -> &mut Self
pub unsafe fn from_glib_ptr_borrow_mut( ptr: &mut *mut GdkTextureDownloader, ) -> &mut Self
Borrows the underlying C value mutably.
Source§impl TextureDownloader
impl TextureDownloader
Sourcepub fn new(texture: &impl IsA<Texture>) -> TextureDownloader
pub fn new(texture: &impl IsA<Texture>) -> TextureDownloader
Sourcepub fn download_bytes(&self) -> (Bytes, usize)
pub fn download_bytes(&self) -> (Bytes, usize)
Downloads the given texture pixels into a GBytes
. The rowstride will
be stored in the stride value.
This function will abort if it tries to download a large texture and
fails to allocate memory. If you think that may happen, you should handle
memory allocation yourself and use Gdk::TextureDownloader::download_into()
once allocation succeeded.
§Returns
The downloaded pixels
§out_stride
The stride of the resulting data in bytes
Sourcepub fn format(&self) -> MemoryFormat
pub fn format(&self) -> MemoryFormat
Sourcepub fn set_format(&mut self, format: MemoryFormat)
pub fn set_format(&mut self, format: MemoryFormat)
Sets the format the downloader will download.
By default, GDK_MEMORY_DEFAULT is set.
§format
the format to use
Sourcepub fn set_texture(&mut self, texture: &impl IsA<Texture>)
pub fn set_texture(&mut self, texture: &impl IsA<Texture>)
