It's not properly checking the arch, and none of our compilers use it.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The GCC-LLVM compilers on Snow Leopard have advanced enough to make them worth the effort to make sure they at least work again. These are the minimum changes needed to make things work. The current gcc-llvm compilers on Mac OS X support Objective-C++ so, no need to special case them anymore either. You STILL need to make sure your path is correct however.

It provides a device-independent and vendor-neutral interface - for sophisticated 2D graphical applications, while allowing device manufacturers to - provide hardware acceleration where appropriate. + OpenVG is optimized for 2D vector operations, and closely matches + the functionality in QPainter.

If this is not the case, then + modifications may be needed to the code under \c{src/gui/egl} and + \c{src/plugins/graphicssystems/openvg} to accomodate the EGL + implementation. + + The ShivaVG graphics system under \c{src/plugins/graphicssystems/shivavg} + is an example of how to integrate a non-EGL implementation of + OpenVG into Qt. It is currently only supported with Qt/X11 + and being an example only, the resulting screen output may not + be as good as with other OpenVG engines. + + \section1 Using the OpenVG graphics system + + Once the graphics system plugin has been built and installed, + applications can be run as follows to use the plugin: + + \code + app -graphicssystem OpenVG + \endcode + + If ShivaVG is being used, then substitute \c ShivaVG instead of + \c OpenVG in the line above. + + If the plugin fails to load, try setting the \c QT_DEBUG_PLUGINS + environment variable to 1 and try again. Usually the plugin + cannot be loaded because Qt cannot locate it in the directory + \c{plugins/graphicssystems} within the Qt installation, or the + dynamic library path does not include the directory containing + the system's \c libOpenVG.so library. + + \section1 Supported features + + \section2 Context modes + + The default configuration is "single-context" mode, where a single + EGLContext object is used for all drawing, regardless of the surface. + Multiple EGLSurfaces are created, one for each window surface or pixmap. + eglMakeCurrent() is called with the same EGLContext every time, but a + different EGLSurface. + + Single-context mode is necessary for QPixmapData to be implemented in + terms of a VGImage. If single-context mode is not enabled, then QPixmapData + will use the fallback QRasterPixmapData implementation, which is less + efficient performance-wise. + + Single-context mode can be disabled with the QVG_NO_SINGLE_CONTEXT define + if the OpenVG engine does not support one context with multiple surfaces. + + \section2 Transformation matrices + + All affine and projective transformation matrices are supported. + + QVGPaintEngine will use the engine to accelerate affine transformation + matrices only. When a projective transformation matrix is used, + QVGPaintEngine will transform the coordinates before passing them + to the engine. This will probably incur a performance penalty. + + Pixmaps and images are always transformed by the engine, because + OpenVG specifies that projective transformations must work for images. + + It is recommended that client applications should avoid using projective + transformations for non-image elements in performance critical code. + + \section2 Composition modes + + The following composition modes are supported: + + \list + \o QPainter::CompositionMode_SourceOver + \o QPainter::CompositionMode_DestinationOver + \o QPainter::CompositionMode_Source + \o QPainter::CompositionMode_SourceIn + \o QPainter::CompositionMode_DestinationIn + \o QPainter::CompositionMode_Plus + \o QPainter::CompositionMode_Multiply + \o QPainter::CompositionMode_Screen + \o QPainter::CompositionMode_Darken + \o QPainter::CompositionMode_Lighten + \endlist + + The other members of QPainter::CompositionMode are not supported + because OpenVG 1.1 does not have an equivalent in its \c VGBlendMode + enumeration. Any attempt to set an unsupported mode will result in + the actual mode being set to QPainter::CompositionMode_SourceOver. + Client applications should avoid using unsupported modes. + + \section2 Pens and brushes + + All pen styles are supported, including cosmetic pens. + + All brush styles are supported except for conical gradients, which are + not supported by OpenVG 1.1. Conical gradients will be converted into a + solid color brush corresponding to the first color in the gradient's + color ramp. + + Affine matrices are supported for brush transforms, but not projective + matrices. + + \section2 Rectangles, lines, and points + + Rectangles and lines use cached VGPath objects to try to accelerate + drawing operations. vgModifyPathCoords() is used to modify the + co-ordinates in the cached VGPath object each time fillRect(), + drawRects(), or drawLines() is called. + + If the engine does not implement vgModifyPathCoords() properly, then the + QVG_NO_MODIFY_PATH define can be set to disable path caching. This will + incur a performance penalty. + + Points are implemented as lines from the point to itself. The cached + line drawing VGPath object is used when drawing points. + + \section2 Polygons and Ellipses + + Polygon and ellipse drawing creates a new VGPath object every time + drawPolygon() or drawEllipse() is called. If the client application is + making heavy use of these functions, the constant creation and destruction + of VGPath objects could have an impact on performance. + + If a projective transformation is active, ellipses are converted into + cubic curves prior to transformation, which may further impact performance. + + Client applications should avoid polygon and ellipse drawing in performance + critical code if possible. + + \section2 Other Objects + + Most other objects (arcs, pies, etc) use drawPath(), which takes a + QPainterPath argument. The default implementation in QPainterEngineEx + converts the QPainterPath into a QVectorPath and then calls draw(), + which in turn converts the QVectorPath into a VGPath for drawing. + + To reduce the overhead, we have overridden drawPath() in QVGPaintEngine + to convert QPainterPath's directly into VGPath's. This should help improve + performance compared to the default implementation. + + Client applications should try to avoid these types of objects in + performance critical code because of the QPainterPath to VGPath + conversion cost. + + \section2 Clipping + + Clipping with QRect, QRectF, and QRegion objects is supported on all + OpenVG engines with vgMask() if the transformation matrix is the identity + or a simple origin translation. + + Clipping with an arbitrary QPainterPath, or setting the clip region when + the transformation matrix is simple, is supported only if the OpenVG engine + has the vgRenderToMask() function (OpenVG 1.1 and higher). + + The QVG_NO_RENDER_TO_MASK define will disable the use of vgRenderToMask(). + + The QVG_SCISSOR_CLIP define will disable clipping with vgMask() or + vgRenderToMask() and instead use the scissor rectangle list to perform + clipping. Clipping with an arbitrary QPainterPath will not be supported. + The QVG_SCISSOR_CLIP define should only be used if the OpenVG engine + does not support vgMask() or vgRenderToMask(). + + \section2 Opacity + + Opacity is supported for all drawing operations. Solid color pens, + solid color brushes, gradient brushes, and image drawing with drawPixmap() + and drawImage() will probably have the best performance compared to + other kinds of pens and brushes. + + \section2 Text Drawing + + If OpenVG 1.1 is used, the paint engine will use VG fonts to cache glyphs + while drawing. If the engine does not support VG fonts correctly, + QVG_NO_DRAW_GLYPHS can be defined to disable this mode. Text drawing + performance will suffer if VG fonts are not used. + + By default, image-based glyphs are used. If QVG_NO_IMAGE_GLYPHS is defined, + then path-based glyphs will be used instead. QVG_NO_IMAGE_GLYPHS is ignored + if QVG_NO_DRAW_GLYPHS is defined. + + If path-based glyphs are used, then the OpenVG engine will need to + support hinting to render text with good results. Image-based glyphs + avoids the need for hinting and will usually give better results than + path-based glyphs. + + \section2 Pixmaps + + In single-context mode, pixmaps will be implemented using VGImage + unless QVG_NO_PIXMAP_DATA is defined. + + QVGPixmapData will convert QImage's into VGImage's when the application + calls drawPixmap(), and the pixmap will be kept in VGImage form for the + lifetime of the QVGPixmapData object. When the application tries to paint + into a QPixmap with QPainter, the data will be converted back into a + QImage and the raster paint engine will be used to render into the QImage. + + This arrangement optimizes for the case of drawing the same static pixmap + over and over (e.g. for icons), but does not optimize the case of drawing + into pixmaps. + + Bitmaps must use QRasterPixmapData. They are not accelerated with + VGImage at present. + + \section2 Pixmap filters + + Convolution, colorize, and drop shadow filters are accelerated using + OpenVG operations. + + \section1 Known issues + + Performance of copying the contents of an OpenVG-rendered window to the + screen needs platform-specific work in the QVGWindowSurface class. + + Clipping with arbitrary non-rectangular paths only works on engines + that support vgRenderToMask(). Simple rectangular paths are supported + on all engines that correctly implement vgMask(). + + The paint engine is not yet thread-safe, so it is not recommended for + use in threaded Qt applications that draw from multiple threads. + Drawing should be limited to the main GUI thread. + + Performance of projective matrices for non-image drawing is not as good + as for affine matrices. + + QPixmap's are implemented as VGImage objects so that they can be quickly + rendered with drawPixmap(). Rendering into a QPixmap using QPainter + will use the default Qt raster paint engine on a QImage copy of the + QPixmap, and will not be accelerated. This issue may be addressed in + a future version of the engine. + + ShivaVG support is highly experimental and limited to Qt/X11. It is + provided as an example of how to integrate a non-EGL engine. */ diff --git a/doc/src/qtscript.qdoc b/doc/src/qtscript.qdoc index ac13ddf..f2ac6c9 100644 --- a/doc/src/qtscript.qdoc +++ b/doc/src/qtscript.qdoc @@ -44,7 +44,7 @@ \title QtScript Module \since 4.3 \contentspage Qt's Modules - \previouspage QtOpenGL + \previouspage QtOpenVG \nextpage QtScriptTools \ingroup modules \ingroup scripting -- cgit v0.12
