From a53e87a84c92444e8a3173f25ce86dcfd536d6a8 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Sat, 6 Dec 2014 21:12:18 +0100 Subject: Bug 1107 - Refine PixelFormat, GLPixelBuffer and DirectDataBufferInt/BufferedImageInt - PixelFormat Refine definition allowing complete format conversion by its attributes instead of static 'knowledge'. - PixelFormat has_a *new* PixelFormat.Composition - PixelFormat.Composition contains all pixel component layout information as required for inspection and conversion. Component names are enumerated via PixelFormat.CType. - PixelFormatUtil.convert(..) utilizes generic conversion based on PixelFormat.Composition rather static type mapping. However, a int32 RGBA static conversion is still supported for performance. Utilizes Bitstream for varying pixel component bit-width. - Complete w/ hashCode() and equals(..) - GLPixelBuffer - Take 'pack' mode into account when determine GLPixelAttributes, i.e. on GLES pack=true (e.g. glReadPixel) only RGBA is guaranteed to work. Hence querying GLPixelAttributes requires the GLProfile, PixelFormat and pack mode. - Complete GLPixelAttributes conversions from PixelFormat or GL format/data-type, while taking GL data-type into account, as well as pack-mode. - Complete w/ hashCode() and equals(..) - SingletonGLPixelBufferProvider queries singleton GLPixelBuffer via - PixelFormat.Composition hostPixelComp, - GLPixelAttributes pixelAttributes, - boolean pack which comprise a unique key, allowing the implementation to utilize a hash map. This is implemented in AWTSingletonGLPixelBufferProvider. This allows distinct singleton GLPixelBuffer for different host PixelFormat (conversion) and GLPixelAttributes (depending on GLProfile). - Removes field 'componentCount' which was 'hacked in' to pass information about an optional host memory layout. Implementations utilizing conversion, e.g. AWTGLPixelBuffer, can implement GLPixelBufferProvider's 'PixelFormat.Composition getHostPixelComp(final GLProfile glp, final int componentCount)' and manage such implementation details, see use-case GLJPanel. - DirectDataBufferInt/BufferedImageInt: Expose underlying NIO ByteBuffer - AWTMisc.createCursor(..) uses DirectDataBufferInt.BufferedImageInt exposed NIO ByteBuffer, allowing to use generic PixelFormatUtil.convert(..). --- src/newt/classes/jogamp/newt/DisplayImpl.java | 2 +- src/newt/classes/jogamp/newt/PointerIconImpl.java | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'src/newt/classes') diff --git a/src/newt/classes/jogamp/newt/DisplayImpl.java b/src/newt/classes/jogamp/newt/DisplayImpl.java index 5f67c95c1..c94d7d40e 100644 --- a/src/newt/classes/jogamp/newt/DisplayImpl.java +++ b/src/newt/classes/jogamp/newt/DisplayImpl.java @@ -165,7 +165,7 @@ public abstract class DisplayImpl extends Display { final PixelRectangle fpixelrect; if( getNativePointerIconPixelFormat() != pixelrect.getPixelformat() || pixelrect.isGLOriented() ) { // conversion ! - fpixelrect = PixelFormatUtil.convert32(pixelrect, getNativePointerIconPixelFormat(), + fpixelrect = PixelFormatUtil.convert(pixelrect, getNativePointerIconPixelFormat(), 0 /* ddestStride */, false /* isGLOriented */, getNativePointerIconForceDirectNIO() ); if( DEBUG_POINTER_ICON ) { System.err.println("createPointerIconRES.0: Conversion-FMT "+pixelrect+" -> "+fpixelrect); diff --git a/src/newt/classes/jogamp/newt/PointerIconImpl.java b/src/newt/classes/jogamp/newt/PointerIconImpl.java index 546a463de..f2b24a3b3 100644 --- a/src/newt/classes/jogamp/newt/PointerIconImpl.java +++ b/src/newt/classes/jogamp/newt/PointerIconImpl.java @@ -154,7 +154,7 @@ public class PointerIconImpl implements PointerIcon { } @Override public final int getStride() { - return size.getWidth() * pixelformat.bytesPerPixel(); + return size.getWidth() * pixelformat.comp.bytesPerPixel(); } @Override public final boolean isGLOriented() { -- cgit v1.2.3
