09/10/2022, 7:00 AMWhat is the most optimal way to write a load of pixels to Canvas or Image? I use drawPixels now, but I have a lot of different colors so that results in a lot of different drawPixels calls. In a non Compose world I'd just fill a bitmap and render that but I have trouble finding this. I see the ImageBitmap and Painter interfaces, but I haven't found a way to use them correctly.

Copy code
val info = ImageInfo.makeN32(1920, 1080, ColorAlphaType.OPAQUE)
val bmp = org.jetbrains.skia.Bitmap()
bmp.allocPixels(info)
bmp.installPixels(byteArray)
imageBitmap = bmp.asComposeImageBitmap()Radoslaw Juszczyk

Copy code
