Patch destination from the source

This option helps us to patch the destination part of the image with the copy of the source(or selected part of the image).

Use transparency while blending patch

This option when enabled uses a transparency factor while blending the patched part

Pattern

The next option helps us to patch the part of the image with a specific pattern.

Diffusion

\
* tells how quickly the patched portion adapts to the surrounding pixels. 
* The more the value, the better
* By default, it is set to 5 and has ranged from 1-7.

\
Content-Aware

Content-Aware Move Tool 

\
* can be used to select and move certain parts of an image
