Hi Brijesh
My scale parameter is basing on image absolute width and height.The width or height of image increase or decrease one percent once.Is there any 8 align with the frame width and height or something like that,as we found the image crop start x ,and start y always what we really want,and the scale center moved, not the orignal position ,then occurs image dithering.How to eliminate the image dithering then ?
best regards
xavier
