GPUCanvasContext: getCurrentTexture() method - Web APIs | MDN
Toggle sidebar
GPUCanvasContext: getCurrentTexture() method
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is available in Web Workers.
The getCurrentTexture() method of the
GPUCanvasContext interface returns the next GPUTexture to be composited to the document by the canvas context.
Syntax
js
getCurrentTexture()
Parameters
None.
Return value
A GPUTexture object instance.
Exceptions
InvalidStateErrorDOMException-
Thrown if
getCurrentTexture()is called on the canvas context before it is configured (i.e., beforeGPUCanvasContext.configure()has been called).
Examples
js
const canvas = document.querySelector("#gpuCanvas");
const context = canvas.getContext("webgpu");
context.configure({
device,
format: navigator.gpu.getPreferredCanvasFormat(),
alphaMode: "premultiplied",
});
// …
// Later on
const commandEncoder = device.createCommandEncoder();
const renderPassDescriptor = {
colorAttachments: [
{
clearValue: [0, 0, 0, 1], // Opaque black
loadOp: "clear",
storeOp: "store",
view: context.getCurrentTexture().createView(),
},
],
};
const passEncoder = commandEncoder.beginRenderPass(renderPassDescriptor);
