Field notes
Panel selection is unusually concrete: the page names common sizes and resolutions, while also allowing a custom resolution up to 2048×2048. Its FAQ explains when to use each output format and points to driver-specific settings for bit order, inversion, rotation, and color planes. The site says cropping and resizing happen in the browser, while a resized copy is sent to the server for dithering and encoding.
