TurboCAD splits large image into pieces (horizontal stripes) in order to save memory while renederingrendering, and then stitches these fragments into a single image.
...
Maximal value – 256 megapixels, corresponds to the image size of 16000 x 16000 (maximum resolution).
If If you set "Tile Area" = 256, then for any size image of fragmentation will not work.
Please Please note: When installing large values "Tile Area" is very likely to be used throughout the computer's memory and system instability.
