Members

version

version : Null<Int>
The WebGL version to request. default: 1
stencil

stencil : Null<Bool>
If the value is true, the drawing buffer has a stencil buffer of at least 8 bits. If the value is false, no stencil buffer is available. snow default: uses render config stencil flag webgl default: false
preserveDrawingBuffer

preserveDrawingBuffer : Null<Bool>
If false, once the drawing buffer is presented as described in theDrawing Buffer section, the contents of the drawing buffer are cleared to their default values. All elements of the drawing buffer (color, depth and stencil) are cleared. If the value is true the buffers will not be cleared and will preserve their values until cleared or overwritten by the author. On some hardware setting the preserveDrawingBuffer flag to true can have significant performance implications. snow default: uses webgl default webgl default: false
premultipliedAlpha

premultipliedAlpha : Null<Bool>
If the value is true the page compositor will assume the drawing buffer contains colors with premultiplied alpha. If the value is false the page compositor will assume that colors in the drawing buffer are not premultiplied. This flag is ignored if the alpha flag is false. snow default: false webgl default: true
preferLowPowerToHighPerformance

preferLowPowerToHighPerformance : Null<Bool>
Provides a hint to the implementation suggesting that, if possible, it creates a context that optimizes for power consumption over performance. For example, on hardware that has more than one GPU, it may be the case that one of them is less powerful but also uses less power. An implementation may choose to, and may have to, ignore this hint. snow default: uses webgl default webgl default: false
failIfMajorPerformanceCaveat

failIfMajorPerformanceCaveat : Null<Bool>
If the value is true, context creation will fail if the implementation determines that the performance of the created WebGL context would be dramatically lower than that of a native application making equivalent OpenGL calls. snow default: uses webgl default webgl default: false
depth

depth : Null<Bool>
If the value is true, the drawing buffer has a depth buffer of at least 16 bits. If the value is false, no depth buffer is available. snow default: uses render config depth flag webgl default:true
antialias

antialias : Null<Bool>
If the value is true and the implementation supports antialiasing the drawing buffer will perform antialiasing using its choice of technique (multisample/supersample) and quality. If the value is false or the implementation does not support antialiasing, no antialiasing is performed snow default: uses render config antialias flag webgl default: true
alpha

alpha : Null<Bool>
If the value is true, the drawing buffer has an alpha channel for the purposes of performing OpenGL destination alpha operations and compositing with the page. If the value is false, no alpha buffer is available. snow default: false webgl default:true
