ContextConfigAttributes

​

Data object ContextConfigAttributes

interface struct ContextConfigAttributes

Interface that encapsulates various client desired attributes related to context configuration. ContextConfigAttributes helps clients choose the desired context configuration. Clients can retrieve a set of supported and available context configurations (IContextConfig) based on a ContextConfigAttributes object. While creating IContext and IGraphicsSurface, the desired IContextConfig object needs to be passed in. While building ContextConfigAttributes, clients must set each mandatory field explicitly. A field is mandatory unless marked as optional.

Fields

​

numRedBits

i32 — Required

Number of red bits in color buffer. System would use optimal value if ‘-1’ is passed.

​

numGreenBits

i32 — Required

Number of green bits in color buffer. System would use optimal value if ‘-1’ is passed.

​

numBlueBits

i32 — Required

Number of blue bits in color buffer. System would use optimal value if ‘-1’ is passed.

​

numAlphaBits

i32 — Required

Number of alpha bits in color buffer. System would use optimal value if ‘-1’ is passed.

​

numDepthBits

i32 — Required

Number of depth bits in depth buffer. System would use optimal value if ‘-1’ is passed.

​

numStencilBits

i32 — Required

Number of stencil bits in stencil buffer. System would use optimal value if ‘-1’ is passed.

​

needPackedDepthStencilBuffer

bool — Required

Needs a packed depth stencil buffer.

​

numSamplesPerPixel

i32 — Required

Number of samples per pixel. System would use optimal value if ‘-1’ is passed.

​

presentationMode

PresentationMode — Required

Refers to how images are presented to the screen

​

compressionPolicy

CompressionPolicy — Required

Refers to levels of internal compression system can enable.

​

isLossyCompressionOk

bool — Required

Indicates if lossy compression is OK

​

nativeConfigAttributes

i32[] — Required

Array of native attributes and their values. Most clients should’t have to pass anything for this unless they need some native config attributes which couldn’t be represented by above ones. This is an optional field.
