Expand description

This trait is enabled with the ole feature, and provides methods for IPicture.

Prefer importing this trait through the prelude:

use winsafe::prelude::*;

Provided Methods§

Source

Returns the value in HIMETRIC units.

§Examples

Converting height from HIMETRIC to pixels:

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

let pic: w::IPicture; // initialized somewhere
let pic = unsafe { w::IPicture::null() };

let cy_hm = pic.get_Height()?;
let hdc_screen = w::HWND::NULL.GetDC()?;
let (_, cy_px) = hdc_screen.HiMetricToPixel(0, cy_hm);

Source

fn get_hPal(&self) -> HrResult<HPALETTE>

IPicture::get_hPal method.

Source

fn get_KeepOriginalFormat(&self) -> HrResult<bool>

IPicture::get_KeepOriginalFormat method.

Source

fn get_Type(&self) -> HrResult<PICTYPE>

IPicture::get_Type method.

Source

fn get_Width(&self) -> HrResult<i32>

IPicture::get_Width method.

Returns the value in HIMETRIC units.

§Examples

Converting width from HIMETRIC to pixels:

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

let pic: w::IPicture; // initialized somewhere
let pic = unsafe { w::IPicture::null() };

let cx_hm = pic.get_Width()?;
let hdc_screen = w::HWND::NULL.GetDC()?;
let (cx_px, _) = hdc_screen.HiMetricToPixel(cx_hm, 0);

Source

fn PictureChanged(&self) -> HrResult<()>

IPicture::PictureChanged method.

Source

fn put_KeepOriginalFormat(&self, keep: bool) -> HrResult<()>

IPicture::put_KeepOriginalFormat method.

Source

fn Render( &self, hdc: &HDC, dest_pt: Option<POINT>, dest_sz: Option<SIZE>, src_offset_himetric: Option<POINT>, src_extent_himetric: Option<SIZE>, metafile_bounds: Option<&RECT>, ) -> AnyResult<()>

IPicture::Render method.

This method will automatically perform the inverse height calculations – convert src_extent_himetric.cy to a negative value and compensate src_offset_himetric.y. This is necessary because HIMETRIC height is rendered in reverse order (bottom to top) when compared to HDC height.
