PSET4: Scale factor between 0 and 1

Question

I am currently working on resize (more comfortable).

my code works with check50 for all scale factors greater than and equal to one (meaning to say it will get a perfect on resize less comfortable). However, factors between 0 and 1 somehow should affect the size of the file headers, specifically bf.bfSize.

Conceptually, how does the scale factor affect these BMP header sizes?

My code is here: https://pastebin.com/4BRrcBZS The most important part to focus on is the lines within the rows of '/'

Thanks in advance~

Not sure what problems you're seeing, but I have a pretty good theory about what's causing the problem.

float f = atol(argv[1]);

The atol() function converts a string into a long int, in other words, an integer! That means that anything less than 1 becomes 0.

Maybe you should consider atof() ? Of course, that's going to present new problems as the code doesn't know how to handle fractional scaling.
