Struct gdk_pixbuf::Pixbuf

source ·
#[repr(transparent)]
pub struct Pixbuf { /* private fields */ }

Implementations§

Available on crate feature v2_40 only.

Creates a Pixbuf from a type implementing Read (like File).

use std::fs::File;
use gdk_pixbuf::Pixbuf;

let f = File::open("some_file.png").expect("failed to open image");
let pixbuf = Pixbuf::from_read(f).expect("failed to load image");

Returns a mutable slice to the pixbuf’s pixel data.

This function will cause an implicit copy if the pixbuf was created from read-only data.

Please see the section on image data for information about how the pixel data is stored in memory.

Safety

No other reference to this pixbuf’s data must exist when this method is called.

Until you drop the returned reference, you must not call any methods on the pixbuf which may read or write to the data.
