The Quality parameter defines whether the image should be delivered as:

Name Definition
Default The source colour
Gray Grayscale
Bitonal Each pixel is black or white
Color The color image. This could be a colorized black and white image

This can be useful for some image processing tools like OCR generation. To see what types a image server supports you can look into the info.json profile section:


profile": [

        "supports": [
        "qualities": [
