I'm so close, but my program does not pass check50 because it doesn't resize a 1x1 BMP correctly when n is 1, 2, 3, 5 (i.e., when it needs padding).
When I use peek to compare with staff for 1x1 and n = 1, I see the problem is with biSizeImage
. Staff has that as 24. Mine is 36. I don't get it. How can the size be 24? Isn't it 3 (width) + 1 (padding) * 3 (abs of height) * 3 (triple size) = 36?
Seems like it could be a padding issue, but even staff.bmp
is 90 bytes. How could they get from 24 for image size + 54 for header info to add up to 90?
