My Hanjie Process IX

If you have visited my Mental Exercise blog, you are probably aware of the fact that I have been making hanjie/nongram/griddler/crosspic/piccross/edel/Japanese puzzles for years. I have decided to show my process from start to finish on how I actually put these together including development of the image, preparing the numbers, testing, and conversion to PDF.
Last time, we finished making the puzzle. At least we hope we did. Not all puzzles are possible, so we need to test. We will start in the spreadsheet at: https://onedrive.live.com/redir?resid=2e6efb80915ed5bd!8539&authkey=!AGwW_344InPXWIA&ithint=file%2cxlsx in worksheet 12. This is the blank grid that we developed.

Here's a little tip for solving these puzzles. Large numbers can really help. Let's start with the largest. The 11th row shows a 2 and a 25.

If you start from the left, imagine the first 2 cells are shaded, the next cell is unshaded, and then the next 25 are shaded. This is the furthest left that these cells can be shaded.

Similarly, we can look at the right 25 cells as the furthest right the cells can be shaded.

We know how far left the 25 can go. We know how far right it can go. It can also go somewhere in between. These can be found in worksheet 13.

In all of these possible locations for the 25, there are 13 cells that are always shaded.

We don't know any cells that have to be left unshaded, and we don't have enough information at this point to find any cells that have to be a part of the 2. In the puzzle, we will leave most of our cells with the gray fill. The 13 cells that we know are part of the 25 will be filled with black. This is also in worksheet 13.

If you look back, you can see that the shaded section is essentially where the overlap is for the furthest left and furthest right the 25 can go. This is how I will refer to this type of shaded segment in the future.
