Directwrite api

DirectWrite has multiple layers of functionality, including text layout, script processing, glyph rendering, and the font system. Physical Fonts It will be helpful in the discussion that follows to distinguish between logical and physical fonts. However, what I mean by a physical font in the context of computer typography is the actual data that defines the appearance of text in a particular font.

Applications can choose to use it exclusively with CPU, the so-called software rendering by using it in conjunction with WARP10 in situations when hardware capability is not available, such as when running within a device with minimal GPU support, under terminal serviceWindows session 0or when directwrite api rendering is performed in a remote server with the graphical result sent back to the client device.

Direct2D performance and memory usage scale linearly with primitive counts in both software and hardware. Direct2D [6] [7] supports high-quality rendering with the following key features: Boolean operationspath widening, outlining, etc.

Composite layers Primitive blend modes e. Such interoperability allows developers to gradually replace critical code paths with Direct2D code without the need to overhaul their entire source code.

This release also introduced a brand-new API extension to support digital ink, which is highly leveraged by the brand-new Microsoft Edge browser as well as the new ink canvas XAML control.

The result is a set of pixel-space trapezoids and additional shaded geometry to compute fractional coverage for the left and right edges of the trapezoids. These trapezoids and shaded geometry are then rasterized by the GPU. The resulting performance is generally better than entirely CPU-based approaches and requires no ancillary storage for multisample or stencil state ; Direct2D renders directly into an aliased framebuffer with properly antialiased results.

First, we optimized our implementation of tessellation when rendering simple geometries like rectangles, lines, rounded rectangles, and ellipses.

Dramatic improvements were made possible because of that partnership. If another fill mode is used e. Since hardware tessellation is available in base Direct3D11 not necessarily Windows 8 on non-TIR hardware.DirectWrite API This page is automatically generated from the assembly documentation.

It provides links between managed types and methods in the barnweddingvt.com2D1 assembly and the original documentation of the DirectWrite API on MSDN.

I'm toying with a little 2D game engine in C# and decided to use Direct2D and DirectWrite for rendering. I know there's the Windows API Code Pack and SlimDX, but I'd really like to dig in and write. The following sections describe the DirectWrite API in detail. In this section. Topic Description; Functions: DirectWrite provides the following function.

All other operations are performed by using DirectWrite interface objects that are created by the IDWriteFactory object that is created with the function below. DirectWrite API This page is automatically generated from the assembly documentation.

It provides links between managed types and methods in the barnweddingvt.com2D1 assembly and the original documentation of the DirectWrite API on MSDN. DirectWrite is an incredibly powerful text layout API.

It powers practically all of the leading Windows applications and technologies, from the Windows Runtime (WinRT) implementation of XAML and Office , to Internet Explorer 11 and more. To use the DirectWrite API, include the dwrite.h header. Like Direct2D, DirectWrite uses a factory, IDWriteFactory to create text objects.

Use the DWriteCreateFactory function to create a factory, and then use its Create methods to create DirectWrite resources (such as IDWriteTextFormat).
