How to write the fastest Direct 2 D app

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

// create a bitmap size dpi. X dpi. Y // preserve pre-existing target Com. Ptr<ID 2 D 1 Image> nullptr 0

// render to the scene. Bitmap // render scene. Bitmap to old. Target

// create an opacity bitmap size dpi. X dpi. Y // preserve pre-existing target Com. Ptr<ID 2 D 1 Image> nullptr 0

// render to the opacity. Bitmap // call Fill. Opacity. Bitmap()

// 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 bounds. Rect geometric. Mask

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

Draw text fast

// Create text layout once text length max. Width max. Height // draw the text layout repeatedly origin

Gray. Scale text rendering mode • Set the rendering mode to grayscale explicitly • Set. Text. Anti. Alias. Mode(D 2 D 1_TEXT_ANTIALIAS_MODE_GRAYSCALE)
