WorldWind Kotlin/earth.worldwind.render.image/[ios]ImageTexture

ImageTexture

open class ImageTexture(image: ImageData) : Texture

iOS GL texture backed by tightly-packed RGBA8 bytes from ImageDecoder. The pixel format is fixed to RGBA8 (premultiplied) — same as Android and JS — so the standard texImage2D(ByteArray) overload can upload directly without extra format conversion.

Lifecycle: holds a strong reference to rgbaBytes until the first allocTexImage call, then drops it so the CPU copy can be GC'd while the GPU keeps the texture.

getTexParameter

fun getTexParameter(name: Int): Int

getTextureName

fun getTextureName(dc: DrawContext): KglTexture

release
