Screenshot only capturing upper-left corner of the visible window

[1hella]

I'm having trouble capturing the entire page. It appears to only be capturing the top-left corner of the page.

webDriver.navigate().to("https://www.reddit.com/");
				
String screenshotDirectoryPath = "target/site/screenshots/test/";
new File(screenshotDirectoryPath).mkdirs();
		
String outputFileName = "reddit.jpg";
File outputFile = new File(screenshotDirectoryPath + "/" + outputFileName);

Screenshot takeScreenshot = new AShot()
		.shootingStrategy(ShootingStrategies.viewportPasting(100))
		.takeScreenshot(Browser.getDriver());
BufferedImage image = takeScreenshot.getImage();

try {
	ImageIO.write(image, "jpg", outputFile);
} catch (IOException e1) {
	System.out.println("Unable to save screenshot");
	e1.printStackTrace();
}

Here's the screenshot I get with this code:

And here's a comparable screenshot I got using a chrome plugin:

Specs:

• Google Chrome 59.0.3071.115 (Official Build) (64-bit)
• Chromedriver 2.29
• Mac OS Sierra 10.12.5
• 2880 x 1800 resolution
• Selenium 3.4.0
• Java 8

@1hella Thanks for report! I guess it is related to #96

No problem. Is there anything I can do to help?

@1hella Sorry for confusing you. The problem is that your screen DPR is 2 (Retina display). Taken image is 4 times bigger than it actually is. We have workaround for it. Take a look to ShootingStrategies factory. You can find viewportRetina method there. That's exactly you are looking for.

@pazone Got it, thanks.

Changing from .shootingStrategy(ShootingStrategies.viewportPasting(100)) to .shootingStrategy(ShootingStrategies.viewportRetina(100, 0, 0, 2)) works for me.

image size got reduced and only capturing the current viewport in MacOS High Sierra (Chrome and Firefox)
final Screenshot screenshot = new AShot().shootingStrategy(ShootingStrategies.viewportRetina(100, 0, 0, 2)).takeScreenshot(driver);
