Struct winsafe::IPicture

pub struct IPicture(/* private fields */);

Available on crate feature ole only.

IPicture COM interface over IPictureVT.

Automatically calls Release when the object goes out of scope.

Examples

Loading an image from bytes:

use winsafe::{self as w, prelude::*};

let image_bytes: Vec<u8>; // initialized somewhere

let stream = w::SHCreateMemStream(&image_bytes)?;
let ipic = w::OleLoadPicture(&stream, None, true)?;

impl ole_IUnknown for IPicture

const IID: IID = _

The COM interface ID.

unsafe fn from_ptr(p: *mut c_void) -> Self

Creates an object from a COM virtual table pointer.

unsafe fn as_mut(&mut self) -> &mut *mut c_void

Returns a mutable reference do the underlying COM virtual table pointer.

fn ptr(&self) -> *mut c_void

Returns the pointer to the underlying COM virtual table.

unsafe fn null() -> Self

Creates an object from a null COM virtual table pointer.

fn leak(&mut self) -> *mut c_void

Returns the pointer to the underlying COM virtual table and sets the internal pointer to null, so that Release won’t be called.
