Add API to read CF_BITMAP

Is it possible to write an image file to clipboard currently?

[DoumanAsh]

Sadly no, I'm only able to read BMP as CF_DIB

I wasn't sure how to write it so I left it for now.
I would welcome help because I'm really not familiar with these aspects on winapi

Is it correct that I saw that the image module is not exposed (even included) in the library?
I've recently managed to extract a CF_BITMAP from the clipboard. You can check the code here (the get_clipboard_bitmap function):

I'm too not familiar with using winapi from rust, but maybe we can work together to implement this feature?
Anyways, thanks for the crate!

I've been having such a hard time placing an image into the clipboard, that I've decided to wait.
At first I was trying to do this with the API directly, but it's really not straight forward.
Since I'm new to both Rust and the winapi, I wont be much help implementing it, but I totally support you guys !
I'll be a day one user !

Ok, I'll give it a try on this weekend and will try to implement simple API to serialize BMP into suitable format for clipboard

[DoumanAsh]

@matheuslessarodrigues I wasn't able to make CF_BITMAP work and only CF_DIB works via https://docs.rs/clipboard-win/3.0.2/clipboard_win/struct.Clipboard.html#method.get_dib

I'll give your code a try on this weekend

I tired using CF_DIB however it almost worked: I could not get to generate valid bmp from a print from ShareX.

Also, sorry about this but I just dicovered that the code I posted does NOT work in release mode.
Oh well, I'll try to fix it before you try it.

Just updated the code in https://github.com/matheuslessarodrigues/copycat/blob/master/src/main.rs
After wrapping some unsafe code, I managed to make it work in release mode as well. I think rust was trying to deallocate some
memory twice.

Btw, that code was translated from this: https://docs.microsoft.com/en-us/windows/win32/gdi/storing-an-image

[DoumanAsh]

hm you probably could just make PR? :)
I'd just review your code

[vamolessa]

Just made one! #13
