BitmaskLabels
The Bitmask tag is for pixel-wise image segmentation tasks, and is used in the area where you want to apply a mask or use a brush to draw a region on the image.
Bitmask operates on the pixel level and outputs a base64-encoded PNG data URL image with black pixels on transparent background.
Export data example: data-url:image/png;[base64-encoded-string]

You need to set smoothing="false" on the <Image> tag to be able to work with individual pixels.
