Confirm Grid Size
Confirm how many rows and columns of cells the grid on this chart page contains. You can let Markup R-XP work it out automatically with a contrast slider, or type the numbers in yourself.

What this step is for
You have just told Markup R-XP where the four corners of the grid sit. Now it needs to know how the area inside those corners is divided up: how many cells across (columns) and how many cells down (rows).
The cell count is what powers everything from this point onward - symbol detection, page-to-page tiling, marking stitches off as you work. If it is wrong by even one row or column, the grid lines drawn over your chart will drift further and further from the printed lines as you move across the page.
The wizard title updates live to show the count it currently has, for example “Confirm Grid Size (45x60)”. That count is what will be saved when you tap Done.
The screen at a glance
Auto and Manual modes
The two chips represent two different ways of arriving at the right cell count, and only one is active at a time. Tap a chip's body to switch into that mode - the active chip is outlined in amber.
Note. Touching the AUTO slider automatically switches into Auto mode; touching the MAN. row/column controls switches into Manual mode. You rarely need to tap the chip body explicitly - just touch the control you want to use.
Auto mode: the contrast slider
In Auto mode, Markup R-XP looks at the contrast between the printed grid lines and the background of the page to work out where each row and column sits. The slider controls how dark a line has to be before it is counted as a grid line.
- Slide the contrast value up or down. A lower value treats more faint marks as grid lines; a higher value only counts the boldest lines.
- Watch the grid lines on the chart redraw. Each change to the slider triggers a fresh detection pass. The wizard title and the cell count refresh too.
- Stop when the detected row and column count match the printed grid. Check the title bar: “Confirm Grid Size (45x60)” should match what is on the page.
Tip. If your chart has both a thin everyday grid and bold every-ten-cells grid, try the slider near the middle first - that usually picks up both.
Manual mode: rows and columns
In Manual mode you set the row and column counts directly. This is the right choice when the auto detection cannot find the grid, when the grid is partially obscured, or when you know the count from the original pattern instructions.
- Tap the ROWS or COLS value to bring up a numeric keyboard. Type the count and confirm.
- Or drag the value up and down to scrub it. Each scrub is a small step at slow speeds and a large step at fast speeds, so big and small changes are both quick.
- Or use the tiny chevron arrows beside the number to step it by one.
- Watch the grid lines redraw on the page. They divide the area inside your corners evenly according to your count.
Note. When you change a row or column count by hand, the wizard automatically switches into Manual mode. This stops the auto-detection from overwriting your number on the next slider tweak.
Showing and hiding the grid
The button beside the contrast slider on the AUTO chip toggles the detected grid lines on and off without changing the count.
Tap the icon again to bring the lines back. A brief toast confirms each change: “Grid lines shown” or “Grid lines hidden”.
Done or carry on to straightening
When the count is correct and the grid lines sit on top of the printed lines, you have two ways to leave this step.
Done
Saves the corners and the cell count straight to the project and takes you back to the Review Grids screen. Use this when the grid looks good and you do not need to straighten anything further.
Straighten Chart
Moves on to the Straighten Chart step, where you can fine-tune the grid intersections one by one if the chart was printed slightly skewed and the simple deskew has not fully cleaned it up.
Heads up. If your row count or column count is zero you will see a toast - “Unable to commit changes with 0 counts” - and the step will not save. Bump both values up before trying again.
Tap Back in the bottom-left corner if you want to return to Set Corners and reposition the corner handles.
Tips and common questions
Here are answers to the most common questions about confirming the grid size.
Q: The auto-detected count is one or two off. Should I tweak the slider or switch to manual?
Answer: Try the slider first.
A small move in either direction is often enough to pick up or drop the missing rows. If the slider cannot get it right - because the missing lines are too faint, too bold or too irregular - switch to manual and type the exact count from the printed pattern.
Q: I know my chart is 100 x 100 cells. Can I just type that and skip the slider?
Answer: Yes.
Tap one of the row/column values in the MAN. chip, type the number on the numeric keyboard, and repeat for the other dimension. Manual mode is the fastest path when you already know the answer.
Q: Why do the grid lines redraw a moment after I move the slider, not instantly?
Answer: Markup R-XP waits a fraction of a second to let your slider settle before re-running the detection.
This is so you can scrub freely without the app working overtime on every intermediate value. Stop moving for a moment and the new grid will appear.
Q: The cell count is right but the lines look slightly skewed. Should I worry?
Answer: Tap Straighten Chart instead of Done.
That step lets you nudge individual intersections to land exactly on the printed grid. It is the easiest way to deal with pages that were scanned at a small angle.
Q: I hid the grid by accident. How do I get it back?
Answer: Tap the grid icon on the AUTO chip again.
The icon toggles between a filled grid and an empty square. The icon you see is the state it will switch to next.
What's next?
If you tap Done, you go back to the Review Grids screen with this page's grid now saved.
If you tap Straighten Chart, the next step is Straighten Chart, where you can fine-tune individual grid intersections on a skewed scan before saving.
