No secrets at all. I have already "published" all steps involved, except for splitting the NA & SP pdfs to individual pdf files. All steps are scripted, except for the initial compromise when it comes to size/resolution used, after that, yes it could all be glued together, ...
But, there is a "but", the individual monthly pictures are not identical when it comes to geo referencing. For example The Cape of Good Hope is not on the same pixels in the Jan sheet as in the Sept sheet and so on. So in the end I have to adjust the tif2bsb header(template) file for each month, manually, by checking them in Gimp. This is also necessary because of a "hack" to force OpenCPN
to display the monthly charts in the right order.
