[Enhancement] Printing summary texts on Checked OMR images

[Udayraj123]

This issue extends #156

• Currently printing score and answers_summary on the final image

Provide access to omr response in printing

We can also pass **omr_response in a new format string that can help us print custom_labels etc on the image.

Support custom colors

We can take custom colors and thickness for each summary text in a font object

Support for new lines in the texts

cv2 putText doesn't seem to support newlines by default
We can use this answer as a util: https://stackoverflow.com/a/73471951/6242649

Handling custom page_dimensions

using "page_dimensions" in evaluation.json will not work currently because all bubble positions are relative to template.pageDimensions
We can use a transformation matrix to map all the field bubbles to the resized page dimensions

Hey @Vishal35198, you can try out the repo's dev branch for this task. We can discuss a basic approach for it in this thread, then I'll assign it to you :)

Can you please give a brief overview of the problem cause i can't grasp it properly please let me know.

@Vishal35198 sure, you'll need to checkout the dev branch locally and after installations, check the output of bonus marking answer key sample -

python3 main.py -i samples/3-answer-key/bonus-marking 

In this sample folder we already have a evaluation.json file with current summary texts configured.

The output should look like this -

Now in the scope of this issue:

• Provide access to omr response in printing i.e. the configuration should support printing omr_response["roll"] or any other keys and values present in omr_response as part of summary texts
