Hi,

Looks like you are essentially trying to do the following:

1) Crop the image.

2) Rotate the image.

3) Mark certain points on the image.

But the image1.jpg after the first 2 transformations does not match with image2.jpg.

Please let me know if doing the above 3 transformations was your query ?
