Floatsnip

Capture any area of your screen and use the captured image as a window.

Features

Keep a captured image on screen as a "Float window". It can stay on top of other windows.
Zoom a Float window with the mouse wheel, change its opacity with Ctrl + wheel, and rotate or flip it with Shift + arrow keys.
Capture a selected area, a selected window, a saved area, a saved window, or the active window.
Assign a hotkey to each type of capture.
Save as JPG or PNG, copy to the clipboard, or open the image in another application.
Works with multiple monitors and high-DPI displays.
The interface is available in Japanese and English.

Installing and removing

Install: extract the 7z file anywhere you like and run Floatsnip.exe in the Main folder. There is no installer.
Update: extract the new 7z file and replace your existing Floatsnip.exe with the new one. Your settings are kept.
Remove: delete the extracted folder. Check the Images folder first for any images you want to keep.

Open the "VersionInfo" window in the app to check whether a newer version is available.
