Halcon 放大顯示目標區域

* 計算區域的外接矩形
smallest_rectangle1 (CharRotatedAll, Row1, Column1, Row2, Column2)
ZoomHeight := Row2 - Row1 + 1
ZoomWidth := Column2 - Column1 + 1
ZoomFactor := min([768 / ZoomWidth,576 / ZoomHeight])
ZoomRow := (Row1 + Row2) / 2
ZoomColumn := (Column1 + Column2) / 2
* 修改圖像的顯示部分
* 768原圖的寬 576原圖的高
 dev_set_part (ZoomRow - 576 / ZoomFactor / 2, ZoomColumn - 768 / ZoomFactor / 2, ZoomRow + 576 / ZoomFactor / 2 - 1, ZoomColumn + 768 / ZoomFactor / 2 - 1)
