Functions

fun makeFromBackendRenderTarget(context: DirectContext, rt: BackendRenderTarget, origin: SurfaceOrigin, colorFormat: SurfaceColorFormat, colorSpace: ColorSpace?, surfaceProps: SurfaceProps? = null): Surface?

Wraps a GPU-backed buffer into Surface.

makeFromMTKView

fun makeFromMTKView(context: DirectContext, mtkViewPtr: NativePointer, origin: SurfaceOrigin, sampleCount: Int, colorFormat: SurfaceColorFormat, colorSpace: ColorSpace?, surfaceProps: SurfaceProps?): Surface

makeNull

fun makeNull(width: Int, height: Int): Surface

Returns Surface without backing pixels. Drawing to Canvas returned from Surface has no effect. Calling makeImageSnapshot() on returned Surface returns null.

makeRaster

fun makeRaster(imageInfo: ImageInfo): Surface

Allocates raster Surface. Canvas returned by Surface draws directly into pixels. Allocates and zeroes pixel memory. Pixel memory size is imageInfo.height() times imageInfo.minRowBytes(). Pixel memory is deleted when Surface is deleted.

fun makeRaster(imageInfo: ImageInfo, rowBytes: Int): Surface

fun makeRaster(imageInfo: ImageInfo, rowBytes: Int, surfaceProps: SurfaceProps?): Surface

Allocates raster Surface. Canvas returned by Surface draws directly into pixels. Allocates and zeroes pixel memory. Pixel memory size is imageInfo.height() times rowBytes, or times imageInfo.minRowBytes() if rowBytes is zero. Pixel memory is deleted when Surface is deleted.

makeRasterDirect

fun makeRasterDirect(pixmap: Pixmap): Surface

fun makeRasterDirect(pixmap: Pixmap, surfaceProps: SurfaceProps?): Surface

fun makeRasterDirect(imageInfo: ImageInfo, pixelsPtr: NativePointer, rowBytes: Int): Surface

fun makeRasterDirect(imageInfo: ImageInfo, pixelsPtr: NativePointer, rowBytes: Int, surfaceProps: SurfaceProps?): Surface

Allocates raster Surface. Canvas returned by Surface draws directly into pixels.

makeRasterN32Premul

fun makeRasterN32Premul(width: Int, height: Int): Surface

Allocates raster Surface.

makeRenderTarget

fun makeRenderTarget(context: DirectContext, budgeted: Boolean, imageInfo: ImageInfo): Surface

fun makeRenderTarget(context: DirectContext, budgeted: Boolean, imageInfo: ImageInfo, sampleCount: Int, surfaceProps: SurfaceProps?): Surface

fun makeRenderTarget(context: DirectContext, budgeted: Boolean, imageInfo: ImageInfo, sampleCount: Int, origin: SurfaceOrigin, surfaceProps: SurfaceProps?): Surface

fun makeRenderTarget(context: DirectContext, budgeted: Boolean, imageInfo: ImageInfo, sampleCount: Int, origin: SurfaceOrigin, surfaceProps: SurfaceProps?, shouldCreateWithMips: Boolean): Surface

Returns Surface on GPU indicated by context. Allocates memory for pixels, based on the width, height, and ColorType in ImageInfo. describes the pixel format in ColorType, and transparency in AlphaType, and color matching in ColorSpace.
