And QPainter can do this across a + variety of different hardware and software stacks. Naturally the + underlying combination of hardware and software has some + implications for performance, and ensuring that every single + operation is fast in combination with all the various combinations + of composition modes, brushes, clipping, transformation, etc, is + close to an impossible task because of the number of + permutations. As a compromise we have selected a subset of the + QPainter API and backends, were performance is guaranteed to be as + good as we can sensibly get it for the given combination of + hardware and software. + + The backends we focus on as high-performance engines are: + + \list + + \o Raster - This backend implements all rendering in pure software + and is always used to render into QImages. For optimal performance + only use the format types QImage::Format_ARGB32_Premultiplied, + QImage::Format_RGB32 or QImage::Format_RGB16. Any other format, + including QImage::Format_ARGB32, has significantly worse + performance. This engine is also used by default on Windows and on + QWS. It can be used as default graphics system on any + OS/hardware/software combination by passing \c {-graphicssystem + raster} on the command line + + \o OpenGL 2.0 (ES) - This backend is the primary backend for + hardware accelerated graphics. It can be run on desktop machines + and embedded devices supporting the OpenGL 2.0 or OpenGL/ES 2.0 + specification. This includes most graphics chips produced in the + last couple of years. The engine can be enabled by using QPainter + onto a QGLWidget or by passing \c {-graphicssystem opengl} on the + command line when the underlying system supports it. + + \o OpenVG - This backend implements the Khronos standard for 2D + and Vector Graphics. It is primarily for embedded devices with + hardware support for OpenVG.

When you specify a + family, you can either use the old hyphenated "foundry-family" + format or the bracketed "family [foundry]" format; for example: + "Cronyx-Helvetica" or "Helvetica [Cronyx]". If the family has a + foundry it is always returned using the bracketed format, as is + the case with the value returned by families(). The font() function returns a QFont given a family, style and point size. diff --git a/src/gui/text/qfontengine.cpp b/src/gui/text/qfontengine.cpp index 27fc3c1..d364025 100644 --- a/src/gui/text/qfontengine.cpp +++ b/src/gui/text/qfontengine.cpp @@ -185,22 +185,11 @@ QFontEngine::QFontEngine() QFontEngine::~QFontEngine() { - for (GlyphPointerHash::const_iterator it = m_glyphPointerHash.constBegin(), - end = m_glyphPointerHash.constEnd(); it != end; ++it) { - for (QList<QFontEngineGlyphCache*>::const_iterator it2 = it.value().constBegin(), - end2 = it.value().constEnd(); it2 != end2; ++it2) { - delete *it2; - } - } - m_glyphPointerHash.clear(); - for (GlyphIntHash::const_iterator it = m_glyphIntHash.constBegin(), - end = m_glyphIntHash.constEnd(); it != end; ++it) { - for (QList<QFontEngineGlyphCache*>::const_iterator it2 = it.value().constBegin(), - end2 = it.value().constEnd(); it2 != end2; ++it2) { - delete *it2; - } + for (QLinkedList<GlyphCacheEntry>::const_iterator it = m_glyphCaches.constBegin(), + end = m_glyphCaches.constEnd(); it != end; ++it) { + delete it->cache; } - m_glyphIntHash.clear(); + m_glyphCaches.clear(); qHBFreeFace(hbFace); } @@ -713,103 +702,30 @@ QByteArray QFontEngine::getSfntTable(uint tag) const return table; } -void QFontEngine::expireGlyphCache() -{ - if (m_glyphCacheQueue.count() > 10) { // hold only 10 caches in memory. - QFontEngineGlyphCache *old = m_glyphCacheQueue.takeFirst(); - // remove the value from either of our hashes - for (GlyphPointerHash::iterator i = m_glyphPointerHash.begin(); i != m_glyphPointerHash.end(); ++i) { - QList<QFontEngineGlyphCache *> list = i.value(); - if (list.removeAll(old)) { - if (list.isEmpty()) - m_glyphPointerHash.remove(i.key()); - else - m_glyphPointerHash.insert(i.key(), list); - break; - } - } - for (GlyphIntHash::iterator i = m_glyphIntHash.begin(); i != m_glyphIntHash.end(); ++i) { - QList<QFontEngineGlyphCache *> list = i.value(); - if (list.removeAll(old)) { - if (list.isEmpty()) - m_glyphIntHash.remove(i.key()); - else - m_glyphIntHash.insert(i.key(), list); - break; - } - } - delete old; - } -} - void QFontEngine::setGlyphCache(void *key, QFontEngineGlyphCache *data) { Q_ASSERT(data); - QList<QFontEngineGlyphCache*> items = m_glyphPointerHash.value(key); - - for (QList<QFontEngineGlyphCache*>::iterator it = items.begin(), end = items.end(); it != end; ++it) { - QFontEngineGlyphCache *c = *it; - if (qtransform_equals_no_translate(c->m_transform, data->m_transform)) { - if (c == data) - return; - items.removeAll(c); - delete c; - break; - } - } - items.append(data); - m_glyphPointerHash.insert(key, items); - m_glyphCacheQueue.append(data); - expireGlyphCache(); -} + GlyphCacheEntry entry = { key, data }; + if (m_glyphCaches.contains(entry)) + return; -void QFontEngine::setGlyphCache(QFontEngineGlyphCache::Type key, QFontEngineGlyphCache *data) -{ - Q_ASSERT(data); - QList<QFontEngineGlyphCache*> items = m_glyphIntHash.value(key); - - for (QList<QFontEngineGlyphCache*>::iterator it = items.begin(), end = items.end(); it != end; ++it) { - QFontEngineGlyphCache *c = *it; - if (qtransform_equals_no_translate(c->m_transform, data->m_transform)) { - if (c == data) - return; - items.removeAll(c); - delete c; - break; - } - } - items.append(data); - m_glyphIntHash.insert(key, items); + // Limit the glyph caches to 4.
