traxy -- Transform an X,Y position from input to output pixel position using the same conventions as drizzle traxy xin yin . xin = 400 [real] . ... The X dimension of the input image (this is used to determine the centre which is the origin of the transformations). (nyin = 800) [real] . ... So, if an object on an input image at a certain position is drizzled with a given set of parameters then the position of that object on the output can be predicted using traxy with the same parameter values. ...
