The maximum allowed image size is 680x680 pixels (this is library restriction). In application it might be restricted even further.

The only reason for having this restriction is a processing power of the device. Even for this relatively small image it might take up to 300 ms (depending upon device, of course). If decoding time is not an issue for you, we can increase the size and recompile the library, as you wish.

The ISO 16022 Standard requires so called Quiet Zone around the Data Matrix symbol. The width of this zone shall not be less than 2 Matrix module (cell) size.

In Online Decoder we “artificially” reconstruct Quiet Zone around the submitted symbol (about 20 pixels wide at each side) to ensure compliance with the ISO Standard. That is why our decoder was able to decode submitted symbols, which actually have no Quiet Zone around themselves.
