Returns A file stream that contains the rendered region
Example /region?sessionId=sessionId&pathOrUid=path&timeframe=0&layer=0&channels=0&channelClipping=0,0&channelColor=ffffffff&gamma=1&x=0&y=0&width=1000&height=1000&scale=0.1
In the example request above, the system will render a 1000×1000 pixel portion of the full resolution image and scale it to 100×100 pixels before it returns it to the client.

| orientation | Optional The orientation of the macro (0 = auto; 1 = vertical; 2 = horizontal) |
| w | Optional Expected output width of the macro |
| h | Optional Expected output height of the macro |
Returns An image
Example /macro?sessionId=sessionId&pathOrUid=path
/barcode Renders the associated barcode of a slide
