Pixels between vertices will be linearly interpolated. The colors can contain transparency.</p> <p>The geometry to be rendered with vertex color must have the following layout. Attribute position 0 must contain vertices. Attribute position 1 must contain colors, a tuple of 4 values with RGBA layout. Both floats in the range of 0 to 1 and unsigned bytes in the range 0 to 255 are valid for the color values.</p> <p><b>Note: </b>The rendering pipeline expects pixels with premultiplied alpha.</p><p><a href="qsggeometry.html#defaultAttributes_ColoredPoint2D">QSGGeometry::defaultAttributes_ColoredPoint2D</a>() can be used to construct an attribute set that is compatible with this material.</p> <p>The vertex color material respects both current opacity and current matrix when updating it's rendering state.</p> </div> <!-- @@@QSGVertexColorMaterial --> <div class="func"> <h2>Member Function Documentation</h2> <!-- $$$QSGVertexColorMaterial[overload1]$$$QSGVertexColorMaterial --> <h3 class="fn" id="QSGVertexColorMaterial"><a name="QSGVertexColorMaterial"></a>QSGVertexColorMaterial::<span class="name">QSGVertexColorMaterial</span>()</h3> <p>Creates a new vertex color material.</p> <!-- @@@QSGVertexColorMaterial --> </div> </div> </div> </div> </div> </div> <div class="footer"> <p> <acronym title="Copyright">©</acronym> 2017 The Qt Company Ltd.
