From bd98b927b910d9421e63cf0dbc2b746eec019f80 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Wed, 8 Jan 2014 21:56:26 +0100 Subject: Bug 935: NEWT PointerIcon: Utilize Toolkit Agnostic PixelFormat and Conversion Utilities (Allowing 'arbitrary' PointerIcon data input) Commit fe28bc125429b38cdcd016746081f4a6d521c6fd added the notion of toolkit agnostic PixelFormat and conversion utilities, utilized and further tested by this patch. +++ - PointerIcon is a PixelRectangle and hence holds the decoded data. This allows on-the-fly conversion if required as well as recreation w/o PNG re-decoding. - Using array-backed PointerIcon data where possible, allowing better performance when converting PixelFormat etc. - NEWT Display adds 'createPointerIcon(final IOUtil.ClassResources pngResource...' method to support agnostic PointerIcon creation. - NEWT Display adds methods to allow users to avoid PixelFormat and Buffer NIO type forced conversion: - PixelFormat getNativePointerIconPixelFormat() - boolean getNativePointerIconForceDirectNIO() +++ PNGImage -> PNGPixelRect Deleted: com.jogamp.opengl.util.texture.spi.PNGImage Added: com.jogamp.opengl.util.PNGPixelRect (We hope nobody was using PNGImage directly since it was a service-plugin for TextureIO) PNGPixelRect is a PixelRectangle PNGPixelRect actually is implemented OpenGL agnostic, however - since our PNGJ support lives under package 'jogamp.opengl.util.pngj' it cannot be moved up (yet). PNGPixelRect now handles all PixelFormat for the target format and also added support for grayscale+alpha (2 channels). The latter is force-converted to RGB* - similar to paletted. Further more, PNGPixelRect allows simply passing an OutputStream to write the PNG data. Used by: TextureIO and NEWT +++ - OffscreenSurfaceLayer's setCursor(..) uses the agnostic PixelRectangle instead of a PNG resource. - AWTMisc uses the PixelRectangle to produce the AWT Cursor and converts it to the required format. Hence same pixels are used for NEWT and AWT pointer/cursor icon. - TestGearsES2Newt and NewtAWTReparentingKeyAdapter 'tests' iterate over 3 custom PointerIcon when pressed 'c'. - JOGLNewtAppletBase uses the new custom PointerIcon 'newt/data/crosshair-lumina-trans-32x32.png', which is included in NEWT (213 bytes only). - --- .../com/jogamp/opengl/util/PNGPixelRect.java | 335 +++++++++++++++++++++ 1 file changed, 335 insertions(+) create mode 100644 src/jogl/classes/com/jogamp/opengl/util/PNGPixelRect.java (limited to 'src/jogl/classes/com/jogamp/opengl/util/PNGPixelRect.java') diff --git a/src/jogl/classes/com/jogamp/opengl/util/PNGPixelRect.java b/src/jogl/classes/com/jogamp/opengl/util/PNGPixelRect.java new file mode 100644 index 000000000..1bbc12f32 --- /dev/null +++ b/src/jogl/classes/com/jogamp/opengl/util/PNGPixelRect.java @@ -0,0 +1,335 @@ +/** + * Copyright 2012 JogAmp Community.
