Hi Alexander,
Please review updated patch. http://cr.openjdk.java.net/~pkbalakr/8162959/webrev.01/ Added a new public API "Image createHiDPIScreenCapture(Rectangle screenRect)". Returns an ordinary screenshot(BufferedImage) if the UI scale is 1. Returns MultiResolutionImage for HiDPI display with two resolution variants, 1. Low Resolution/base image with user input width and height, I have used interpolation algorithm for scaling , adapted from JavaFX Robot (http://hg.openjdk.java.net/openjfx/9-dev/rt/rev/89a5de54b7dc), 2. High Resolution image with scaled width and height .

Patch: http://hg.openjdk.java.net/openjfx/9-dev/rt/rev/89a5de54b7dc New Public API " BufferedImage createScreenCapture(Rectangle screenRect, boolean isHiDPI)" is added, Which will have a parameter to specify if HiDPI. It is better to a add public method which returns MultiResolution image on HiDPI display and consists of two resoltion variants - base image which has size requested by a user - high-resolution image which creates an original screen capture The proposed by your algorithm can be applied to the base image. For more details see JDK-8020618 [macosx] java.awt.Robot makes blurry screen captures on Retina Thanks, Alexandr. Regards, Prem
