イメージをセグメント化するときに、ループは完全な列をスキップします

Question

私は、スクリーンショットをセグメント化し、グリッドのようなスクリーンショットをループすることで、あらかじめ定義された各ブロックを、実際のグリッドサイズは10X8です。それは2列目をスキップしています。私はブロックを100回書き直したので、私の論理的な欠陥について教えてください、過去3日間で10種類の方法は無駄です。

 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 

修正：1ではなく

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