如何通过脚本编写多个ROI作为DM中的图像？

Question

我想将这两个投资回报率裁剪为两张图片：

我正在考虑通过脚本同步裁剪这两个ROI，我找到了一个关于由D. R. G. Mitchell从ROI创建图像的代码。所以我写了这个：

image front := GetFrontImage()
imagedisplay imgdisp = front.ImageGetImageDisplay(0)
number roinum = imgdisp.ImageDisplayCountRois()
number x

for (x=0; x<roinum; x++)
{
roidisp = ImageDisplayGetROI(imgdisp,x)
image crop = front []
ShowImage(crop)
}

但它实际上只适用于一个投资回报率。如果您能给我一些关于如何处理多个ROI裁剪的线索，我将不胜感激。谢谢！

此示例可以帮助您：

// ROIs are objects of the image display, so get that one first
Image input := GetFrontImage()
ImageDisplay disp = input.ImageGetImageDisplay(0)

// Iterate over all ROIs found on the display
number nRoi = disp.ImageDisplayCountROIs()
for (number i=0; i<nRoi; i++ )
{
    ROI myRoi = disp.ImageDisplayGetROI( i )

    // Test if the ROI has the properties you want
    if ( !myROI.ROIIsRectangle() )  continue
    if ( !myROI.ROIGetVolatile() )  continue

    // Read the ROI region and use that to copy the data
    number t, l, b, r 
    myROI.ROIGetRectangle( t, l, b, r )

    // Use slice2 to address the area and ImageClone to get a clone
    // inclusing tags, calibration etc.
    image cut := input.Slice2(t,l,0, 0,(r-l),1, 1,(b-t),1 ).ImageClone()
    cut.ShowImage()

    // Optionally set some names
    cut.SetName( input.GetName()+" #"+(i+1) )

    // Optionally modify the roi
    myRoi.ROISetVolatile( 0 )
    myRoi.ROISetMoveable( 0 )
    myRoi.ROISetLabel( "cut #"+(i+1) )
}
