Development of Windows 8 Direct2D-Metro application example based on Visual Studio 11 (2) international text display

Direct2d is used by Microsoft to replace DirectDraw and new technologies such as GDI and GDI + [1]. It mainly provides 2D animation hardware acceleration. Currently, it only supports Windows Vista SP2 and Windows 7 and later [2].
 
The direct2d technical architecture is built on the direct3d 10.1 API. It can build 2D images through hardware acceleration and fully supports transparent and Alpha mixing. Direct2d also supports software Rasterizer (software Rasterizer), that is, when the video card does not support hardware acceleration, direct2d can still be depicted using software, and the effect is still better than that of GDI.
 
Direct2d can use dxgi (DirectX graphics infrastructure) and interactive operations. direct2d also supports directwrite.
 
Direct2d Supports high-quality rendering and has the following features:
Supports cleartype text rendering (provided by directwrite)
Remove the original image (per primitive antialiasing)
Draw and fill in geometric shapes (straight lines, curves) and bitmap.
Solid color and linearity.
Depicts the middle layer.
Multiple geometric operations (such as unions, intersections, widening, and outlining)

The direct template is provided in Microsoft vs11.

 

After creating an application,
