commit for feature developing invert-replace color of a pdf for stirl…

[Hashim0510]

Based on the discussion, I have developed the three varieties of functionality to replace text and background colors of a pdf and invert full colors of pdf.

I have created a replace-invert-color API to process the PDF. There are totally 3 options given for user. Please take a look at the image for understanding.

1. Default high contrast color ---> user will have a default list of standard colors for background and text as discussed before. Please take a look at the image for understanding.

2. Custom Color ---> user will have option to provide custom colors for text and background Please take a look at the image for understanding.

3. Full invert --->> user can be able to invert the full colors of pdf Please take a look at the image for understanding.

I did all corner case manual tests for all three options. I am attaching the pdf outputs with this.

Input PDF for all options: test_document_complex-2.pdf

output for high contrast option: high-contrast-color-output.pdf

output for custom color option: custom-color-replace-output.pdf

output for full inversion: full-invert-output.pdf
