how could I make a larger kernel for motion blur?

[HoiweCheng]

I read the code of linedictionary, but failed to figure out what it means? is there anything to support it?

LineDictionary defines the coordinates wrt the kernel matrix of the two points identifying each possible line, these are then used in LinearMotionBlur.LineKernel to "draw" the line on the kernel matrix, setting the relevant values to 1. The keys of the different dict values are the angles of the lines each set of point coordinates refers to

If you want to make a larger linear blur kernel, just follow this logic and add what you need to LineDictionary

@HoiweCheng Hope this help
