The way that you set the bounds seems right. The range that you set is
small and doesn't include a buffer to add more features to the file
later, but that's sufficient for things to work.
What do you mean by "coordinates of the points in the tab file are very
large compared to the original file"? Is an error introduced by the lib?
Can you show us the coordinates that you get to compare with the
expected coordinates?
