GPUCanvasContext: getConfiguration() method - Web APIs | MDN
Toggle sidebar
GPUCanvasContext: getConfiguration() 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 getConfiguration() method of the
GPUCanvasContext interface returns the current configuration set for the context.
Syntax
js
getConfiguration()
Parameters
None.
Return value
An object containing the configuration options set on the context (i.e., via the GPUCanvasContext.configure() method), or null if no configuration is set (either no configuration was previously set, or a configuration was set and then GPUCanvasContext.unconfigure() was called on the context).
Examples
js
const canvas = document.querySelector("canvas");
const context = canvas.getContext("webgpu");
if (!navigator.gpu) {
throw Error("WebGPU not supported.");
}
const adapter = await navigator.gpu.requestAdapter();
if (!adapter) {
throw Error("Couldn't request WebGPU adapter.");
}
const device = await adapter.requestDevice();
context.configure({
device,
format: navigator.gpu.getPreferredCanvasFormat(),
alphaMode: "premultiplied",
});
console.log(context.getConfiguration());
/* Logs something like:
{
"alphaMode": "premultiplied",
"colorSpace": "srgb",
"device": { ... },
"format": "bgra8unorm",
"toneMapping": {
"mode": "standard"
},
"usage": 16,
"viewFormats": []
}
