D.4. Bezier curves(50,90) (10,50)(50,50)(90,50)(50,10)Figure D.5: Two Bezier curves<strong>The</strong> Bezier curves are actually drawn as a linearized form using a series of rectangularblobs of ink. Left to itself, La<strong>TeX</strong> will attempt to pick the number of blobs to give thesmoothest looking curve, up to a maximum number. (Each blob takes up space in La<strong>TeX</strong>’sinternal memory, and it may run out of space if too many are used in one picture.) <strong>The</strong>maximum number of blobs per Bezier curve is set by the \qbeziermax command. Thiscan be adjusted with the \renewcommand command. For example:\renewcommand{\qbeziermax}{250}will set the maximum number of blobs to be 250.Another method of controlling the number of blobs is by the optional 〈num〉 argumentto the \qbezier command. If used, it must be a positive integer number which tells La<strong>TeX</strong>exactly how many blobs to use for the curve.427
