From 4035ec3e9ed5ef904dd6f22adaf5e9deb24e9455 Mon Sep 17 00:00:00 2001 From: Kim Motoyoshi Kalland Date: Wed, 22 Sep 2010 12:12:57 +0200 Subject: Revert "Fixed painter path drawing on FBO without stencil buffer." This reverts commit 89cbb165600de9a557a8a621dc41b93c2a7a2b52. The patch should be applied to Qt 4.8, not 4.7. --- .../gl2paintengineex/qpaintengineex_opengl2.cpp | 26 ---------------------- src/opengl/qglframebufferobject.cpp | 4 ---- 2 files changed, 30 deletions(-) diff --git a/src/opengl/gl2paintengineex/qpaintengineex_opengl2.cpp b/src/opengl/gl2paintengineex/qpaintengineex_opengl2.cpp index 2347e66..aa217f6 100644 --- a/src/opengl/gl2paintengineex/qpaintengineex_opengl2.cpp +++ b/src/opengl/gl2paintengineex/qpaintengineex_opengl2.cpp @@ -866,32 +866,6 @@ void QGL2PaintEngineExPrivate::fill(const QVectorPath& path) if (do_vectorpath_cache) path.makeCacheable(); - if (!device->format().stencil()) { - // If there is no stencil buffer, triangulate the path instead. - - QRectF bbox = path.controlPointRect(); - // If the path doesn't fit within these limits, it is possible that the triangulation will fail. - bool withinLimits = (bbox.left() > -0x8000 * inverseScale) - && (bbox.right() < 0x8000 * inverseScale) - && (bbox.top() > -0x8000 * inverseScale) - && (bbox.bottom() < 0x8000 * inverseScale); - if (withinLimits) { - QTriangleSet polys = qTriangulate(path, QTransform().scale(1 / inverseScale, 1 / inverseScale)); - - QVarLengthArray vertices(polys.vertices.size()); - for (int i = 0; i < polys.vertices.size(); ++i) - vertices[i] = float(inverseScale * polys.vertices.at(i)); - - prepareForDraw(currentBrush.isOpaque()); - setVertexAttributePointer(QT_VERTEX_COORDS_ATTR, vertices.constData()); - glDrawElements(GL_TRIANGLES, polys.indices.size(), GL_UNSIGNED_INT, polys.indices.constData()); - } else { - // We can't handle big, concave painter paths with OpenGL without stencil buffer. - qWarning("Painter path exceeds +/-32767 pixels."); - } - return; - } - // The path is too complicated & needs the stencil technique vertexCoordinateArray.clear(); vertexCoordinateArray.addPath(path, inverseScale, false); diff --git a/src/opengl/qglframebufferobject.cpp b/src/opengl/qglframebufferobject.cpp index 7c84946..ba23cab 100644 --- a/src/opengl/qglframebufferobject.cpp +++ b/src/opengl/qglframebufferobject.cpp @@ -324,10 +324,6 @@ void QGLFBOGLPaintDevice::setFBO(QGLFramebufferObject* f, fboFormat.setStencil(true); } else if (attachment == QGLFramebufferObject::Depth) { fboFormat.setDepth(true); - fboFormat.setStencil(false); - } else { - fboFormat.setDepth(false); - fboFormat.setStencil(false); } GLenum format = f->format().internalTextureFormat(); -- cgit v0.12
