BitmaskLabels

The BitmaskLabels tag for pixel-wise image segmentation tasks is used in the area where you want to apply a mask or use a brush to draw a region on the image.

BitmaskLabels operates on 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]

Note: You need to set smoothing="false" on the Image tag to be able to work with individual pixels;

Use with the following data types: image.
