I have a movieclip with center registration. I am allowing the user to rotate and crop the  portion.if the rotation is 0, then i can able to crop the image. if image is rotate then i am not able to crop the particular portion. i am setting the translate value tx = width/2 and ty=height//2. i doubted the problem is in translate. thats the reason i am asking for the assiging of tx and ty.

if the image is rotated, what shape is used to crop the image and how are you cropping the image?

after the image is rotated, i am using graphics to get the x,y,wd,ht and using bitmap i am copying the portion

are you using the draw() method with a cliprectangle? 

if so, what's the problem?  if not, what specifically are you using to crop?
