The read-only ImageData.pixelFormat property is a string indicating the pixel format of the image data.
The pixel format can be set during ImageData initialization using either the ImageData() constructor or the createImageData() method.
This property can have the following values:
"rgba-unorm8" representing RGBA with 8 bit per component unsigned normalized format, using a Uint8ClampedArray."rgba-float16" representing RGBA with 16 bits per component, using a Float16Array. Floating-point pixel values allow representing colors in arbitrarily wide gamuts and high dynamic range (HDR).Floating-point pixel values allow representing colors in arbitrarily wide gamuts and high dynamic range (HDR). You can set the pixelFormat setting to "rgba-float16" to use RGBA values with 16 bits per component. This requires the dataArray to be a Float16Array.
let floatArray = new Float16Array(4 * 200 * 200);
let imageData = new ImageData(floatArray, 200, 200, {
pixelFormat: "rgba-float16",
});
console.log(imageData.pixelFormat); // "rgba-float16"
