Strategies for SVG drawing

The versions of File:Chess board.svg show several different concepts, worth discussing.

• 1^st version, 2006-10-01 by Nevit (Sodipodi-Inkscape, 13 822 bytes)

barely resembles the appearance of a chess board. The board is a single path (requiring 12 245 bytes) with hundreds of cubic curves resulting in no straight lines. Instead of squares, round irregular structures are shown - but with a useless accuracy of seven decimal fractions.

• 2^nd version, 2009-11-23 by Tryphon (Inkscape 19 941 bytes)

is a chess board. The frame and the 64 rectangles are defined sequentially, with over-attributing for each one (typical of Inkscape svg files), not using any grouping strategies. The path definitions are accurate to one decimal place, but because of the Inkscape-typical transformations five digits are needed to correct the transformation aberration. Each one of the 64 squares need ~233 bytes for definition.

• 3^rd version, 2009-11-23 by AnonMoos (manual review, 3 740 bytes)

still has the 64 + 1 rectangles, but by clever grouping most of the repeated attributes are removed. This is a swift and effective method to reduce file size and redundancies. The transformation deviation needing the avoidable correction with five decimal digits is still in use.

 Info I was just trying to do a quick and easy simplification that would reduce the file size by over 500%, and not trying to rethink the file from scratch... AnonMoos (talk) 12:45, 31 December 2010 (UTC)

• 4^th version, 2010-01-22 by McSush (manual, 519 bytes)

Completely new drawn using more effective methods. With only eight path-drawn rectangles, four horizontal ones overlaid by four vertical ones using the fill-rule evenodd, all is done inside the outer frame rectangle. The coordinates are specified as integers, instead of transformations, and the viewBox is used.

Angoumois

• 5^th version, 2010-05-18 by Tryphon (2×manual, 730 bytes)

Another new concept. After defining four of the squares, they are cloned to a filling pattern for the outer frame. A similar solution can be seen in the vector file Flag of Angoumois, while LinkFA-star Aragon () is another example for filling patterns.

From this version forward, the white squares are actually filled with white; in prior versions they had been transparent.

• 6^th version, 2010-12-26 by Sarang (manual, 368 bytes)

is a revision of the 4th version from McSush. Alternate concepts resulted in larger files, e.g. the stroke-dasharray, used for November () and Checkermotoslogo (), was not the best choice.

 Info Coding as stroke-width="1" and fill="black" is default parameter value and therefore always redundant (except when overwriting another group attribute). Its removal makes a file size of 339 bytes. Sure it will be possible to find more reductions. -- 08:49, 31 December 2010 Sarang

• 7^th version, 2012-01-30 by Sarang (manual, 296 bytes)

revision of 6, removing default values and avoiding negative values

• 8^th version, 2021-04-28 by Cmglee (manual, 229 bytes, with linefeeds 233 bytes)

again a version with viewBox and dasharray, with Cmglee's genial idea to get the first fill with circle which needs only 16 bytes instead of 22 when coded as a path.
