From fe28bc125429b38cdcd016746081f4a6d521c6fd Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Wed, 8 Jan 2014 21:27:20 +0100 Subject: Bug 935: NEWT PointerIcon: Add Toolkit Agnostic PixelFormat and Conversion Utilities (Allowing 'arbitrary' PointerIcon data input) To allowing 'arbitrary' PointerIcon data input, i.e. via raw pixels we need to define an agnostic PixelFormat and required conversion utilities. The latter is not hw accelereated (toolkit agnostic), but this shall be expected and satisfying for small amount of 'pixels'. --- .../javax/media/nativewindow/util/PixelFormat.java | 196 +++++++++++ .../media/nativewindow/util/PixelFormatUtil.java | 374 +++++++++++++++++++++ .../media/nativewindow/util/PixelRectangle.java | 193 +++++++++++ 3 files changed, 763 insertions(+) create mode 100644 src/nativewindow/classes/javax/media/nativewindow/util/PixelFormat.java create mode 100644 src/nativewindow/classes/javax/media/nativewindow/util/PixelFormatUtil.java create mode 100644 src/nativewindow/classes/javax/media/nativewindow/util/PixelRectangle.java (limited to 'src/nativewindow/classes/javax/media') diff --git a/src/nativewindow/classes/javax/media/nativewindow/util/PixelFormat.java b/src/nativewindow/classes/javax/media/nativewindow/util/PixelFormat.java new file mode 100644 index 000000000..823496a92 --- /dev/null +++ b/src/nativewindow/classes/javax/media/nativewindow/util/PixelFormat.java @@ -0,0 +1,196 @@ +/** + * Copyright (c) 2014 JogAmp Community.
