MetalRenderer

MetalRenderer(
    device: MTLDeviceProtocol,
    colorPixelFormat: ULong,
    stencilPixelFormat: ULong,
    sampleCount: Int? = null,
    textureImageStore: TextureImageStore? = null
)

Parameters
`device: MTLDeviceProtocol`	`MTLDevice` to use for rendering.
`colorPixelFormat: ULong`	Format of the color texture being rendered.
`stencilPixelFormat: ULong`	Format of the stencil texture being rendered. If a stencil texture is not being used, this should be `MTLPixelFormatInvalid`.
`sampleCount: Int? = null`	The number of samples per pixel for MSAA. If unset or null, shader-based antialiasing will be used instead.
`textureImageStore: TextureImageStore? = null`	An optional callback for retrieving texture images by ID.

Public functions

draw

fun draw(
    renderEncoder: MTLRenderCommandEncoderProtocol,
    inProgressStroke: InProgressStroke,
    textureWidth: Double,
    textureHeight: Double,
    strokeToScreenTransform: AffineTransform
): Unit

Draws an in-progress stroke using the given render encoder.

Parameters
`renderEncoder: MTLRenderCommandEncoderProtocol`	`MTLRenderCommandEncoder` to draw with.
`inProgressStroke: InProgressStroke`	The in-progress stroke to draw.
`textureWidth: Double`	Width of the texture `renderEncoder` is drawing to, used to compute the projection transform.
`textureHeight: Double`	Height of the texture `renderEncoder` is drawing to, used to compute the projection transform.
`strokeToScreenTransform: AffineTransform`	Affine transform from stroke coordinates to view coordinates.

Parameters
`renderEncoder: MTLRenderCommandEncoderProtocol`	`MTLRenderCommandEncoder` to draw with.
