Image Cropper vTool#
By making an image smaller, you also reduce the size of the image that subsequent vTools work with. This may reduce processing time and may help to avoid incorrect results because irrelevant information is removed. You can specify the size of the resulting image manually. Alternatively, you can use the rectangle output from any vTool that outputs rectangles, e.g., the Rectangle Measurements Pro vTool, as input for the CropArea pin to define the resulting image.
信息
The Image Cropper changes the actual image size and therefore also changes the image's coordinate system. This means that you can't return to the original image. If you want to preserve the original image for later use, consider using the ROI Creator vTool. Using the ROI Creator, you can perform operations on just a portion of the original image without losing the original.
