h04x / win-screenshot Goto Github PK

The screenshot taken by the example (full screen) is completly broken:

use image::RgbaImage;
use win_screenshot::prelude::*;

fn main() {
    let buf = capture_display().unwrap();
    let img = RgbaImage::from_raw(buf.width, buf.height, buf.pixels).unwrap();
    img.save("screenshot.jpg").unwrap();
}

Is it because I cross-compile on ubuntu linux using cargo build --target x86_64-pc-windows-gnu?

I executed the complied example on a virtual (qemu/kvm) win10 machine.

I am really impressed with this crate regarding capturing individual windows!
Capturing works with windows that are

• covered by other windows
• partially outside the monitor space
• on a different Virtual Desktop
• or even overlapping different screens with different scaling/dpi settings

The only thing that is not quite perfect is that if the window is minimized then only a few pixels of the maximize and close button are screenshotted.

Is there a recommended way to programmatically unminimize a window before taking a screenshot?

I'm using win-screenshot to take screenshots of a specific window but there was a little problem with the resulting image. The dimension given to the image does not take into account the window frame and title bar. The resulting image is cropped because of this.

To fix the problem in my project I modified lines 72-73 of lib.rs:

let width = (*rc).right - (*rc).left + 16;
let height = (*rc).bottom - (*rc).top + 39;

It works perfect for my resolution (1920x1080) and windows version (Win10 21H2) but of course it is not an universal fix.

Hi,

Thanks for making win-screenshot! It's basically the only screenshot lib I've found that allows capturing specific windows.

I am capturing a subregion of a window in a loop and found that passing my desired width and height dimensions to CreateCompatibleBitmap is much faster than capturing the whole window and then paring down the image buffer afterwards. Can a new capture_window function be added with x,y,w,h parameters?

Thank you

I have two computers, the one is ok, the second only capture part of the screen.
The captured image is like this:

The full screen is like this:
