Question
To enlarge an image one must fill in new rows and columns with color information based on the colors of neighboring positions in the original image I need help With developing in testing at the function named and large also comparing it with the solution at the end
Programming Exercise 7.11
Instructions
=
Hint. Copy each row of pixels in the
original image to one or more rows in
the new image
To copy a row, use two index
variables, one that starts on the left
of the row and one that starts on the
right. These two indexes converge to
the middle. This will allow you to copy
each pixel to one or more positions of
a row in the new image.)

below:

Instructions
To enlarge an image, one must fill in
new rows and columns with color
information based on the colors of
neighboring positions in the original
image.
• Develop and test a function
named enlarge.
This function should expect an
image and an integer factor as
arguments.
• The function should build and
return a new image that
represents the expansion of the
original image by the factor.
Hint: Copy each row of pixels in the
original image to one or more rows in
the new image
To copy a row, use two index
variables one that starts on the left
