don't understand avisynth crop

Hello, I have captured my video8 movie and want to make it a svcd with dvd2svcd. This goes great but I want to crop also. I searched the forum but I can't seam to find out how the crop works. From the site it is also unclear. I want to crop at the left 6, at right 14, at top 0 and at the bottom 10 from the original movie 720x576. The site says this Crop(left,top,width,height). So I can only crop left and top. How does this work??? (I don't want to resize cause I do this with bicubicresize later.) greetz Vivaatloni

Crop(left,top,new width, new height) new width=(orig width)-(left crop)-(right crop) same with new height

ok cool. Thx for taking the time for explaining it.
