<p>&ldquo;That&rsquo;s an interesting application of write mode 2,&rdquo; you may well say, &ldquo;but is it really useful?&rdquo; While the ability to convert chunky bitmaps into VGA bitmaps does have its uses, Listing 27.1 is primarily intended to illustrate the mechanics of write mode 2.</p>

<h4 id="Heading6">Drawing Color-Patterned Lines Using Write Mode 2</h4>
<p>A more serviceable use of write mode 2 is shown in the program presented in Listing 27.2. The program draws multicolored horizontal, vertical, and diagonal lines, basing the color patterns on passed color tables. Write mode 2 is ideal because in this application color can vary from one pixel to the next, and in write mode 2 all that&rsquo;s required to set pixel color is a change of the lower nibble of the byte written by the CPU. Set/reset could be used to achieve the same result, but an index/data pair of <b>OUT</b>s would be required to set the Set/Reset register to each new color. Similarly, the Map Mask register could be used in write mode 0 to set pixel color, but in this case not only would an index/data pair of <b>OUT</b>s be required but there would also be no guarantee that data already in display memory wouldn&rsquo;t interfere with the color of the pixel being drawn, since the Map Mask register allows only selected planes to be drawn to.</p>
