В то время как сегментирование изображения, цикл пропускает полный столбец

Question

Мне поручено сегментировать скриншот и прокручивать скриншот, как сетка, сохраняющая каждый предопределенный блок как свой собственный образ, как диаграмма ниже. Фактический размер сетки - 10X8. Он продолжает пропускать колонку 2. Пожалуйста, просветите меня по моему логическому изъяну, поскольку я переписал блок if 100 раз, 10 различных способов за последние 3 дня безрезультатно.

 Col1 Col2 Col3 
Row1  1  2 3 
Row2  4  5 6 
Row3  7  8 9

Answer 1

1. $currentColumn is $null 

2. "Initializing Globals" 

3. $currentColumn = 1 

4. $newleftCoord = $startleftCoord #(is 293) 

5. $currentColumn++     #(now 2) 

6. if ($currentColumn -gt 1)   #(Yes, it's 2) 

7. $newleftCoord = $startleftCoord+($currentColumn*$cellwidth) 
       #= 293 + (2*100) 
       #= 493 

       #= jump from 293 to 493 = skipped column 

Fix: число, начиная с 0 вместо 1

293 + 0*100 
293 + 1*100 
293 + 2*100
