CV page images (cv1.png … cv4.png)

These are the pages of soujanya-cv.pdf, shown on /cv/. Regenerate them whenever the CV changes, in two steps.

1. Render each page

pdftoppm -png -scale-to-x 1554 -scale-to-y -1 soujanya-cv.pdf /tmp/cv

1554px wide keeps the images at the size the page has always used. Add or remove cvN.png files if the CV gains or loses a page, and update the <img> list in _pages/cv.md to match.

2. Trim the vertical page margins

Each PDF page carries roughly 150-175px of white at the top and bottom. Left as-is, two of those margins stack between consecutive images and the page reads as a series of separated sheets rather than one continuous document. Trim them to a uniform 40px, keeping the full width so the text columns stay aligned across pages:

from PIL import Image
PAD = 40
for i in (1, 2, 3, 4):
    im = Image.open(f'/tmp/cv-{i}.png')
    g = im.convert('L'); w, h = im.size; px = g.load()
    ink = lambda y: any(px[x, y] < 245 for x in range(0, w, 3))
    top = 0
    while top < h and not ink(top): top += 1
    bot = h - 1
    while bot > top and not ink(bot): bot -= 1
    im.crop((0, max(0, top - PAD), w, min(h, bot + 1 + PAD))).save(f'images/cv{i}.png')

Only the height changes; every image stays 1554px wide.
