halcon在一些应用场景需要缩放图片之后region还需还原回来。调用zoom_image_factor算子：
 

read_image (Image, 'C:/Users/52602/Desktop/微信图片_20210714102520.bmp')
zoom_image_factor (Image, ImageZoomed, 0.4, 0.4, 'constant')

get_image_size (Image, Width, Height)
get_image_size (ImageZoomed, Width1, Height1)

zoom_image_factor (ImageZoomed, ImageZoomed1, Width/(Width1*1.0), Height/(Height1*1.0), 'constant')
get_image_size (ImageZoomed1, Width2, Height2)
