Cant create multiple images in a same java function using Jmagick

[sarita]

I am trying to create multiple images in a same function using Jmagick API . Every time I run my code , images which are getting created are different . I am getting some different colors or pattern or some other color patches on the image. Use case is that , I have to create multiple images in my function and then overlay it on a input image . Can I do it using any other method or in any effective way . I am attaching my code here .
