After to other important part to creat a factory, is the WordToImage component, which is mainly created with three others components:
- A font generator
- A background generator
- A Text paster
This example is a bit more complex one; it takes the usual main three components, but also three deformations, to increase the power of captchas. All three are set to none, a component which create no deformation, see below, and Examples to have more examples of deformations.
