How to implement a similar of photoshop's "patch tool" function?

Question

I have to automatically remove a barcode in a T-Shirt image, like the attached file:

I know I can do it manually in photoshop using the function "patch tool" that replaces the cropped area by image in the surrounded area but I need to either implement a code for that or get an SDK in Delphi to support this process automatically by passing to the function the (X,Y) points of the edges of the barcode.

Does anyone have any ideas?
