Hi all ,Hi ImageEn Team,

I have a picture from a camera that have a vignette. I have also a reference picture from the same camera but the picture is complete white and with the vignette.

I want correct the original picture.

Is there a simple way in ImageEn to do that?
Can anyone describe me the steps?

Thanks a lot
Joerg

Hi Joerg

Can you attach an example image.

Hi Joerg,

Without seeing an example it is not easy to come up with an answer, but I am guessing that this might work:

* Start by loading the images into two TIEBitmap
* Invert the white reference image
* Add it to the other image you want to correct.

I believe you could use TIEBitmap to do that, or you could use scanlines I guess.

Hope this helps

Hello Roy, Hello Nigel,

thanks a lot for your answer. In the attachment you will find the reference picture (Ref1.jpg) and the original picture (Pic1.jpg).

What have I to do, to correct the vignette?

Thanks for your answers
and best wishes from Germany
Joerg
