If you're looking to create a tool like Gyazo, which captures a selected area and uploads, or a Gif capturer tool like GyazoGif, you're looking at the right repository.
WiseCapturer gives you a full control of selecting an area, capturing a gif, and a screenshot, and simply get the captured file with a few of line calls.
Firstly, for your capturing instance, you need to select a capturer - there are currently two capturing tools:
Captures a simple PNG image of the selected area.
Hotkeys
ESCAPE to cancel selection
Captures a gif animation image of the selected area
Hotkeys
ESCAPE to cancel selection
ENTER to finish capture, and save.
Bootstrap is the main class in WiseCapturer, therefore you need to create a new instance of it.
Bootstrap requires an instance of Capturer, any of the capturers I have included in this library.
For instance:
Bootstrap b = new Bootstrap(new ScreenshotCapturer());
To capture an area, you need to call Bootstrap#beginCapture method which requires an instance of ScreenCaptureCallback
for instance:
Bootstrap b = new Bootstrap(new GifCapturer());
b.beginCapture(new ScreenCaptureCallback() {
@Override
public void captureEnded(CapturedImage image) {
System.out.println("Hello World!");
}
});
In the example above, beginCapturer recevies a new instance of ScreenCaptureCallback, that class gets the CapturedImage object from the library, it basiaclly listens and waits till the capturer sends the captured result.
ScreenCaptureCallback#captureEnded gets called by the Capturer class, when the capturing process has ended and is ready to be sent.
The file you receive as a parameter in ScreenCaptureCallback~#captureEnded is the ready file image, you either upload it, or convert it to BufferedImage and do whatever you want. The file is saved into a temporary file, therefore you can't have multiple screenshots at a time.
