Function getSupportedPixelFormats

getSupportedPixelFormats(rasterMimes?: string[]): Promise<string[]>
Probes the browser environment to determine which image MIME types are supported for pixel-level operations. This function performs a one-time check by attempting to convert a OffscreenCanvas to MIME types. The result is cached to prevent redundant hardware-accelerated operations on subsequent calls.
Parameters
- rasterMimes: string[] = defaultRasterMimes
  List of MIME types to check
Returns Promise<string[]>
A Promise resolving to an array of supported MIME types from the rasterMimes list.
Default
```
['image/png',
  'image/jpeg',
  'image/webp',
  'image/avif',
  'image/gif',
  'image/bmp']
```
Throws
If the OffscreenCanvas context cannot be initialized.
Example
```
const supported = await getSupportedPixelFormats();
if (supported.includes('image/avif')) {
  console.log('High-efficiency formats available');
}
```
