How to write the fastest Direct2D app

• • • • • • Animate complex content fast Clip content to an arbitrary shape fast Draw text fast Render Direct2D effects fast Scale performance on multiple cores Draw mixed 2D/3D content fast

// create a bitmap size nullptr 0 dpiX dpiY // preserve pre-existing target ComPtr

// render to the sceneBitmap // render sceneBitmap to oldTarget

// create an opacity bitmap size nullptr 0 dpiX dpiY // preserve pre-existing target ComPtr

// render to the opacityBitmap // call FillOpacityBitmap()

// enables rasterizing only the changed content DXGI_PRESENT_PARAMETERS

Use bitmaps for caching display output Use command list for caching print output.

// create the layer resource // render to the layer with the clipping geometry boundsRect geometricMask

// create opacity bitmap and render content // create opacity brush from the opacity bitmap // call FillGeometry() by passing in the clip geometry and the opacity brush to

Draw text fast

// Create text layout once text length maxWidth maxHeight // draw the text layout repeatedly origin

GrayScale text rendering mode

• • Set the rendering mode to grayscale explicitly SetTextAntiAliasMode(D2D1_TEXT_ANTIALIAS_MODE_GRAYSCALE)
